## ⭐️【Selection】Top 5 NLP Questions
<a name="1-1"></a>
##### Q1.1 How to load your own local dataset to use PaddleNLP's features?
**A:** By using PaddleNLP's `load_dataset`, `MapDataset`, and `IterDataset`, you can easily customize your own dataset. You are also welcome to contribute datasets to the PaddleNLP repo.
When creating a dataset from a local file, we **recommend** providing a reading function based on the format of the local dataset and passing it into `load_dataset()` to create the dataset.
```python
from paddlenlp.datasets import load_dataset
def read(data_path):
with open(data_path, 'r', encoding='utf-8') as f:
# Skip column names
next(f)
for line in f:
words, labels = line.strip('\n').split('\t')
words = words.split('\002')
labels = labels.split('\002')
yield {'tokens': words, 'labels': labels}
# data_path is a parameter for the read() method
map_ds = load_dataset(read, data_path='train.txt', lazy=False)
iter_ds = load_dataset(read, data_path='train.txt', lazy=True)
```
If you are accustomed to using `paddle.io.Dataset/IterableDataset` to create datasets, it is also supported. You can also create datasets from other Python objects such as `List` objects. For more details, please refer to the [official documentation - Custom Dataset](https://paddlenlp.readthedocs.io/zh/latest/data_prepare/dataset_self_defined.html).
<a name="1-2"></a>
##### Q1.2 PaddleNLP downloads built-in datasets and models to a default path. How can the path be modified?
**A:** Built-in datasets and models are downloaded by default to
`$HOME/.paddlenlp/` directory allows downloading to a specified path by configuring environment variables:
(1) On Linux, set `export PPNLP_HOME="xxxx"`. Ensure the path does not contain Chinese characters.
(2) On Windows, similarly configure the environment variable PPNLP_HOME to a path without Chinese characters, then restart.
<a name="1-3"></a>
##### Q1.3 How to save and load a trained model in PaddleNLP?
**A:** (1) PaddleNLP Pre-trained Models
Save:
```python
model.save_pretrained("./checkpoint")
tokenizer.save_pretrained("./checkpoint")
```
Load:
```python
model.from_pretrained("./checkpoint")
tokenizer.from_pretrained("./checkpoint")
```
(2) Standard Models
Save:
```python
emb = paddle.nn.Embedding(10, 10)
layer_state_dict = emb.state_dict()
paddle.save(layer_state_dict, "emb.pdparams") # Save model parameters
```
Load:
```python
emb = paddle.nn.Embedding(10, 10)
load_layer_state_dict = paddle.load("emb.pdparams") # Load model parameters
emb.set_state_dict(load_layer_state_dict) # Set model parameters
```
<a name="1-4"></a>
##### Q1.4 What recommended methods can improve model performance when the training samples are limited?
**A:** Increasing the number of training samples is the most direct approach. Additionally, you can perform warm start based on our open-source [pre-trained models](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/paddlenlp/transformers) and then fine-tune the model with a small dataset. Moreover, for scenarios like classification and matching, [few-shot learning](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/few_shot) can also yield good results.
<a name="1-5"></a>
##### Q1.5 How can model performance be improved to enhance QPS?
**A:** From an engineering perspective, for server-side deployment, you can use the [Paddle Inference](https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/05_inference_deployment/inference/inference_cn.html) high-performance prediction engine for deployment. For GPU prediction of Transformer models, you can use the [FastGeneration](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/paddlenlp/ops) feature provided by PaddleNLP for fast prediction, which integrates [NV FasterTransformer](https://github.com/NVIDIA/FasterTransformer) with enhanced functionality.
From a model strategy perspective, you can use model miniaturization techniques for model compression, such as model distillation and pruning, to achieve acceleration with smaller models. PaddleNLP integrates general small models like ERNIE-Tiny for downstream task fine-tuning. Additionally, PaddleNLP provides [model compression examples](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/model_compression), implementing methods like DynaBERT, TinyBERT, and MiniLM, which can be referenced for distillation and compression of your own models.

## ⭐️【Theory Section】General NLP Issues
<a name="2-2"></a>
##### Q2.1 What methods can address imbalanced data distribution?
**A:** The following methods can optimize the issue of imbalanced class distribution:
(1) Under-sampling: Reduce the number of samples in over-represented classes to make the number of samples in each class similar.
(2) Over-sampling: Increase the number of samples in under-represented classes by duplicating samples to make the number of samples in each class similar.
(3) Adjusting classification threshold: Training a classifier with imbalanced data can bias the model towards the majority class, so instead of using 0.5 as the classification threshold, classify samples as the minority class even with low confidence.
(4) Cost-sensitive learning: For instance, set the `class_weight` parameter in the LR algorithm.
<a name="2-3"></a>
##### Q2.2 How many samples are generally needed when using pre-trained models?
**A:** It is difficult to define a specific number of samples as it depends on the specific task and data quality. If the data quality is good, classification and text matching tasks typically require data in the hundreds, while translation tasks require millions to train a robust model. If the sample size is small, consider data augmentation or few-shot learning.

### Dataset and Data Processing
<a name="3-1"></a>
##### Q3.1 How to introduce additional vocabularies when training pre-trained models with your own dataset?
**A:** Pre-trained models usually come with a tokenizer and dictionary. For most Chinese pre-trained models, such as ERNIE-3.0, character-level input is used, and the tokenizer converts sentences into character-level forms, so the model cannot receive word-level input. If you wish to introduce additional vocabularies, you need to modify the tokenizer and dictionary of the pre-trained model. You can refer to this [blog](https://kexue.fm/archives/7758/comment-page-1#Tokenizer). Additionally, ensure that the embedding matrix includes embeddings for these new words.
Another approach is to use these dictionary words by masking them in the data for a masked language model's secondary pre-training. This way, the model trained through secondary training will include representations of the additional dictionary. Refer to [PaddleNLP Pre-training Data Process](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/model_zoo/ernie-1.0/).
Furthermore, some pre-trained models use word-level or mixed character-word level inputs, making it easier to introduce additional vocabularies. We will continue to enrich the pre-trained models in PaddleNLP.
<a name="训练调优问题"></a>
### Model Training and Optimization
<a name="4-1"></a>
##### Q3.2 How to load your own pre-trained model to use PaddleNLP's features?
**A:** Taking BERT as an example, if trained using PaddleNLP, through
Models saved using the `save_pretrained()` interface can be loaded with `from_pretrained()`:
```python
tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")
model = BertModel.from_pretrained("bert-base-uncased")
```
If the above situation does not apply, you can load the model using the following method. Contributions to the PaddleNLP repository are also welcome.
(1) Load `BertTokenizer` and `BertModel`
```python
tokenizer = BertTokenizer.from_pretrained("bert-base-uncased")
model = BertModel.from_pretrained("bert-base-uncased")
```
(2) Use `save_pretrained()` to generate `model_config.json`, `tokenizer_config.json`, `model_state.pdparams`, and `vocab.txt` files, saving them to `./checkpoint`:
```python
tokenizer.save_pretrained("./checkpoint")
model.save_pretrained("./checkpoint")
```
(3) Modify the `model_config.json` and `tokenizer_config.json` configuration files to specify your own model, then load the model using `from_pretrained()`.
```python
tokenizer = BertTokenizer.from_pretrained("./checkpoint")
model = BertModel.from_pretrained("./checkpoint")
```
<a name="4-2"></a>
##### Q3.3 If training is interrupted and needs to resume with a warm start, how can you ensure the learning rate and optimizer continue iterating from the interruption point?
**A:**
(1) To fully restore the training state, first save the parameters of `lr`, `optimizer`, and `model`:
```python
paddle.save(lr_scheduler.state_dict(), "xxx_lr")
paddle.save(optimizer.state_dict(), "xxx_opt")
paddle.save(model.state_dict(), "xxx_para")
```
(2) Load the `lr`, `optimizer`, and `model` parameters to resume training:
```python
lr_scheduler.set_state_dict(paddle.load("xxxx_lr"))
optimizer.set_state_dict(paddle.load("xxx_opt"))
model.set_state_dict(paddle.load("xxx_para"))
```
<a name="4-3"></a>
##### Q3.4 How to freeze model gradients?
**A:**
There are several methods you can try:
(1) You can directly modify the internal code implementation of PaddleNLP, wrapping the sections where gradients need to be frozen with `paddle.no_grad()`.
The usage of `paddle.no_grad()` is as follows:
`forward()` freezing example:
```python
# Method 1
class Model(nn.Layer):
def __init__(self, ...):
...
def forward(self, ...):
with paddle.no_grad():
...
# Method 2
class Model(nn.Layer):
def __init__(self, ...):
...
@paddle.no_grad()
def forward(self, ...):
...
```
The use of `paddle.no_grad()` is not limited to the internal implementation of the model; it can also wrap external methods, such as:
```python
@paddle.no_grad()
def evaluation(...):
...
model = Model(...)
model.eval()
...
```
(2) Second method: Taking ERNIE as an example, set the `stop_gradient` of the tensor output by the model to True. You can use `register_forward_post_hook` to attempt as follows:
```python
def forward_post_hook(layer, input, output):
output.stop_gradient=True
self.ernie.register_forward_post_hook(forward_post_hook)
```
(3) Third method: Process on the `optimizer`, `model.parameters` is a `List`, and you can filter accordingly by `name` to update/not update certain parameters. This method requires an overall understanding of the network structure's names, as the entity names of the network structure determine the parameter names, which poses a certain threshold for use:
```python
[ p for p in model.parameters() if 'linear' not in p.name] # Here you can filter out the linear layer, and the specific filtering strategy can be set as needed
```
<a name="4-4"></a>
##### Q3.5 How to print evaluation metrics during the eval phase and save model parameters at each epoch?
**A:** The PaddlePaddle main framework provides two methods for training and prediction. One method is to encapsulate the model using [paddle.Model()](https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/Model_cn.html) and complete model training and prediction through high-level APIs such as `Model.fit()`, `Model.evaluate()`, `Model.predict()`, etc.; the other method is the conventional training method based on basic APIs.
(1) For the first method:
- We can set `paddle.Model.fit()`
API's *eval_data* and *eval_freq* parameters are used to print model evaluation metrics during training: the *eval_data* parameter is an iterable validation dataset source, and the *eval_freq* parameter determines the evaluation frequency. When *eval_data* is provided, the default value of *eval_freq* is 1, meaning evaluation occurs once per epoch. Note: Before training, we need to pass the metrics parameter in the `Model.prepare()` interface to print model evaluation metrics during evaluation.
- Regarding model saving, we can set the *save_freq* parameter in `paddle.Model.fit()` to control the frequency of model saving: the default value of *save_freq* is 1, meaning the model is saved once per epoch.
(2) For the second method:
- We provide training and prediction scripts for common tasks in the examples directory of PaddleNLP, such as [GLUE](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/benchmark/glue) and [SQuAD](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/machine_reading_comprehension/SQuAD).
- Developers can refer to the above scripts to develop custom training and prediction scripts.
<a name="4-5"></a>
##### Q3.6 What should be done if the training process unexpectedly exits or hangs?
**A:** Generally, first consider whether there is insufficient memory or GPU memory (if training with a GPU). You can reduce the batch size for training and evaluation.
Note that when reducing the batch size, the learning rate should also be reduced, typically adjusted proportionally.
<a name="4-6"></a>
##### Q3.7 How to ensure consistent results in model validation and testing?
**A:** Inconsistencies in results during validation and testing can generally be addressed by the following solutions:
(1) Ensure that the eval mode is set and that the seed settings related to data ensure data consistency.
(2) If it is a downstream task model, check whether all model parameters have been loaded. Directly using a pre-trained model like bert-base does not include task-related parameters, so ensure that the fine-tuned model is loaded; otherwise, task-related parameters will be randomly initialized, leading to randomness.
(3) Inconsistencies caused by some operators using the CUDNN backend can be avoided by setting environment variables. If the model uses CNN-related operators, you can set `FLAGS_cudnn_deterministic=True`. If the model uses RNN-related operators, you can set `CUBLAS_WORKSPACE_CONFIG=:16:8` or `CUBLAS_WORKSPACE_CONFIG=:4096:2` (available for CUDNN version 10.2 and above, refer to [CUDNN 8 release note](https://docs.nvidia.com/deeplearning/cudnn/archives/cudnn-894/release-notes/index.html)).
<a name="4-7"></a>
##### Q3.8 How does the ERNIE model return intermediate layer outputs?
**A:** The current API design does not retain intermediate layer outputs, but it is straightforward to modify the source code in PaddleNLP. Additionally, you can in `ErnieModel`...
```python
def __init__(self):
# Register a forward_post_hook function for the Layer whose output you want to retain
self.layer.register_forward_post_hook(self.forward_post_hook)
def forward_post_hook(self, module, input, output):
# Save the Layer's output to a global List
global_output_list.append(output)
```
The `forward_post_hook` function will be invoked after the `forward` function call and will save the Layer's output to a global `List`. For more details, refer to [`register_forward_post_hook()`](https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/nn/Layer_cn.html#register_forward_post_hook).
<a name="deployment-issues"></a>
### Prediction Deployment
<a name="5-1"></a>
##### Q3.9 How to deploy a trained PaddleNLP model to a server?
**A:** We recommend developing in dynamic graph mode and deploying in static graph mode.
1. **Dynamic to Static Conversion**
Dynamic to static conversion involves transforming a dynamic graph model into a static graph model suitable for deployment. The dynamic graph interface is more user-friendly, offering an interactive Python-style programming experience, which is more conducive to model development. In contrast, static graphs have a significant performance advantage over dynamic graphs. Thus, dynamic to static conversion provides a bridge that balances development cost and performance. You can refer to the official documentation [Dynamic to Static Graph Documentation](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/guides/04_dygraph_to_static/index_cn.html) and use `paddle.jit.to_static` to complete the conversion. Additionally, PaddleNLP provides examples for exporting static graph models.
2. **Deployment with Paddle Inference**
The model saved after dynamic to static conversion can be deployed with high performance using Paddle Inference. Paddle Inference includes high-performance CPU/GPU Kernels, combined with fine-grained OP horizontal and vertical fusion strategies, and integrates TensorRT to enhance model inference performance. For more details, refer to the documentation [Paddle Inference Introduction](https://paddleinference.paddlepaddle.org.cn/master/product_introduction/inference_intro.html). To help new users understand how to use Paddle Inference with NLP models, PaddleNLP also provides corresponding examples for reference, which can be found in the deploy directory under [/PaddleNLP/examples](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/).
<a name="5-2"></a>
##### Q3.10 How to convert a static graph model into a dynamic graph model?
**A:** First, you need to save the static graph parameters as `ndarray`.
Data, then map the static graph parameter names to the corresponding dynamic graph parameter names, and finally save them as dynamic graph parameters. For more details, refer to the [parameter conversion script](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/paddlenlp/transformers/ernie/static_to_dygraph_params).
<a name="NLP Application Scenarios"></a>
### ⭐️Consultation on Specific Models and Application Scenarios
<a name="6-1"></a>
##### Q4.1 【Lexical Analysis】How to customize labels in the LAC model and continue training?
**A:** Update the label file `tag.dict` and modify the number of labels in CRF accordingly.
Refer to the [custom label example](https://github.com/PaddlePaddle/PaddleNLP/issues/662) and the [incremental training custom LABEL example](https://github.com/PaddlePaddle/PaddleNLP/issues/657).
<a name="6-2"></a>
##### Q4.2 In information extraction tasks, is it recommended to use a pre-trained model + CRF, and how can it be implemented?
**A:** A pre-trained model + CRF is a general method for sequence labeling. Currently, pre-trained models have a strong ability to express sequence information, and it is also possible to directly use pre-trained models for sequence labeling tasks.
<a name="6-3"></a>
##### Q4.3 【Reading Comprehension】How to understand `batched=True` in the `map()` method of `MapDatasets`, and why must the parameter `batched` be set to `True` in reading comprehension tasks?
**A:** `batched=True` means performing the map operation on an entire batch (not necessarily the training batch, but a group of data), i.e., the trans_func in the map accepts a group of data as input rather than mapping each item individually. In reading comprehension tasks, depending on the doc_stride used, a single sample may be converted into multiple features, making individual data mapping infeasible, hence the need to set `batched=True`.
。
<a name="6-4"></a>
##### Q4.4 【Semantic Matching】What is the difference between semantic indexing and semantic matching?
**A:** The core issue that semantic indexing aims to solve is how to quickly and accurately find documents related to a query from a massive number of Docs using ANN indexing. Semantic matching, on the other hand, focuses on modeling more detailed semantic matching information between the query and documents. From another perspective, [semantic indexing](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/semantic_indexing) addresses the recall problem in search and recommendation scenarios, whereas [semantic matching](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/examples/text_matching) deals with the ranking problem. Although the problems they solve are different and the solutions they employ vary significantly, there are some common technical points between them that can be mutually referenced.

##### Q4.5 【Word Tagging】How to customize the addition of named entities and corresponding word classes in the wordtag model?
**A:** It primarily relies on reconstructing data for finetuning, while also updating the termtree information. The wordtag process consists of two steps:
(1) Tokenization using the BIOES scheme;
(2) Matching the tokenized information with the TermTree.
Therefore, we need to:
(1) Ensure correct tokenization, which may depend on the finetune data of wordtag to achieve accurate tokenization;
(2) In wordtag, it is also necessary to annotate the term with the corresponding knowledge information after correct tokenization. The method for customizing the TermTree in wordtag will be provided in future versions.

# Knowledge Distillation from BERT to Bi-LSTM
## Overall Principle Introduction
This example demonstrates knowledge distillation from a BERT model to a smaller Bi-LSTM-based model for specific tasks, primarily referencing the paper [Distilling Task-Specific Knowledge from BERT into Simple Neural Networks](https://arxiv.org/abs/1903.12136). The core principles are as follows:
1. In this case, the larger model (BERT) serves as the teacher model, while the Bi-LSTM model acts as the student model.
2. For knowledge transfer, the student model learns through a distillation-related loss function. In this experiment, we employ the Mean Squared Error (MSE) loss function, where the inputs are the outputs from both the student and teacher models.
3. During the model distillation phase, the authors apply data augmentation to enable the teacher model to express more "dark knowledge" (referring to relationships between low-probability and high-probability classes in classification tasks) for the student model to learn. Three data augmentation strategies are used:
A. **Masking**: Randomly replaces word tokens with `[MASK]` at a specified probability.
B. **POS-guided word replacement**: Substitutes words with others sharing the same POS tag at a defined probability.
C. **n-gram sampling**: Samples n-grams from each data instance at a specified probability, with n ranging within manually set bounds.
## Model Distillation Steps Introduction
This experiment involves three training phases:
1. Fine-tuning BERT on the specific task.
2. Training the Bi-LSTM-based small model on the same task (to evaluate distillation effectiveness).
3. Distilling knowledge from BERT into the Bi-LSTM-based model.
### 1. Fine-tuning BERT (bert-base-uncased) on the Specific Task
To train the fine-tuned BERT model, refer to the [PaddleNLP](https://github.com/PaddlePaddle/PaddleNLP) repository, particularly the [GLUE example](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/examples/benchmark/glue).
Taking the SST-2 task from GLUE as an example, after fine-tuning bert-base-uncased, we obtain a teacher model. The checkpoint with the best Accuracy on the dev set should be saved for distillation in the third step.
### 2. Training the Bi-LSTM-based Small Model
In this example, the small model is a Bi-LSTM-based classification network with the following architecture: `Embedding` → `LSTM` → `Linear` layer with `tanh` activation → fully connected output layer for logits. The `LSTM` layer is defined as:
```python
self.lstm = nn.LSTM(embed_dim, hidden_size, num_layers,
'bidirectional', dropout=dropout_prob)
```
The ``forward`` function is defined as follows:
.. code-block::
def forward(self, x, seq_len):
x_embed = self.embedder(x)
lstm_out, (hidden, _) = self.lstm(
x_embed, sequence_length=seq_len) # Bidirectional LSTM
out = paddle.concat((hidden[-2, :, :], hidden[-1, :, :]), axis=1)
out = paddle.tanh(self.fc(out))
logits = self.output_layer(out)
return logits
3. Data Augmentation Introduction
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In the subsequent distillation process, the training dataset used for distillation doesn't only contain the original data from the dataset, but rather the total data augmented according to methods A and C described in the previous principles.
In most cases, ``alpha`` is set to 0, indicating that hard labels are ignored, and the student model is trained using only the augmented unlabeled data. Based on the soft labels ``teacher_logits`` provided by the teacher model, the student model's ``logits`` are compared.
Calculate the mean squared error loss. Since the data augmentation process generates more data, the student model can learn additional dark knowledge from the teacher model.
The core code for data augmentation is as follows:
.. code-block::
def ngram_sampling(words, words_2=None, p_ng=0.25, ngram_range=(2, 6)):
if np.random.rand() < p_ng:
ngram_len = np.random.randint(ngram_range[0], ngram_range[1] + 1)
ngram_len = min(ngram_len, len(words))
start = np.random.randint(0, len(words) - ngram_len + 1)
words = words[start:start + ngram_len]
if words_2:
words_2 = words_2[start:start + ngram_len]
return words if not words_2 else (words, words_2)
def data_augmentation(data, whole_word_mask=whole_word_mask):
# 1. Masking
words = []
if not whole_word_mask:
tokenized_list = tokenizer.tokenize(data)
words = [
tokenizer.mask_token if np.random.rand() < p_mask else word
for word in tokenized_list
]
else:
for word in data.split():
words += [[tokenizer.mask_token]] if np.random.rand(
) < p_mask else [tokenizer.tokenize(word)]
# 2. N-gram sampling
words = ngram_sampling(words, p_ng=p_ng, ngram_range=ngram_range)
words = flatten(words) if isinstance(words[0], list) else words
new_text = " ".join(words)
return words, new_text
4. Distillation Model
^^^^^^^^^^^^^^^^^^^^^
This step involves distilling the knowledge from teacher model BERT to the Bi-LSTM based student model. The key aspect is to make the student model (Bi-LSTM) learn the output logits from the teacher model. The training dataset used for distillation comes from the data augmented in the previous step. The core code is as follows:
.. code-block::
ce_loss = nn.CrossEntropyLoss() # Cross-entropy loss
mse_loss = nn.MSELoss() # Mean squared error loss
for epoch in range(args.max_epoch):
for i, batch in enumerate(train_data_loader):
bert_input_ids, bert_segment_ids, student_input_ids, seq_len, labels = batch
# Calculate teacher model's forward.
with paddle.no_grad():
teacher_logits = teacher.model(bert_input_ids, bert_segment_ids)
# Calculate student model's forward.
logits = model(student_input_ids, seq_len)
# Calculate the loss, usually args.alpha equals to 0.
loss = args.alpha * ce_loss(logits, labels) + (
1 - args.alpha) * mse_loss(logits, teacher_logits)
loss.backward()
optimizer.step()

Introduction to Model Compression
============
In recent years, Transformer-based language models have achieved substantial progress in NLP tasks such as machine translation, reading comprehension, text matching, and natural language inference. However, the massive number of parameters and computational resource requirements make BERT and its variants challenging to deploy. The development of model compression techniques has alleviated these issues.
Overview of Model Compression
----------------------------
Model compression reduces model storage and accelerates inference speed while maintaining acceptable accuracy. Common model compression methods include model pruning, quantization, and distillation. Below is a brief introduction to these techniques.
Model Pruning
^^^^^^^^^^^^^
Model pruning removes unimportant network connections from a trained model to reduce redundancy and computational load, thereby decreasing model storage and significantly accelerating inference speed.
Quantization
^^^^^^^^^^^^^
Typically, neural network parameters are represented using 32-bit floating-point numbers. However, such high precision is often unnecessary. Quantization reduces model storage by using lower-precision representations (e.g., INT8 instead of Float32). For instance, Stochastic Gradient Descent (SGD) only requires 6-8 bits of precision. Thus, proper quantization can reduce model size while maintaining accuracy and enable efficient CPU execution. Common quantization methods include binary neural networks, ternary weight networks, and XNOR networks.
Distillation
^^^^^^^^^^^^^
Knowledge distillation involves training a student model (with fewer parameters) to mimic a teacher model (with more parameters). The student model learns from the teacher's knowledge, achieving better performance than standalone training. A typical approach is distilling BERT-base to Bi-LSTM or smaller BERT variants. For example, DistilBERT retains 97% of BERT-base's accuracy with 40% fewer parameters and 60% faster inference.
Model Compression Examples
--------------------------
Below are examples of model compression implemented with PaddlePaddle. The tutorial *Knowledge Distillation from BERT to Bi-LSTM* serves as a "Hello World" example for distillation. The *BERT Compression Using DynaBERT's Strategy* demonstrates DynaBERT, which trains multiple subnets of different sizes simultaneously, allowing direct model pruning during inference.

Using DynaBERT's Strategy to Compress BERT
============
This tutorial employs the training strategy from `DynaBERT-Dynamic BERT with Adaptive Width and Depth <https://arxiv.org/abs/2004.04037>`_. The original model is treated as the largest sub-model within a super-network, where a super-network refers to a network encompassing the entire search space. The original model contains multiple Transformer blocks of identical size. Before each training iteration, a sub-model to be trained in the current round is selected. Each sub-model consists of multiple Sub-Transformer blocks of the same size. Each Sub-Transformer block is derived by selecting different widths from the original Transformer block. A Transformer block contains one Multi-Head Attention and one Feed-Forward Network (FFN). The Sub-Transformer block is obtained as follows:
1. A ``Multi-Head Attention`` layer contains multiple heads. When selecting sub-models of different widths, the number of heads is proportionally reduced. For example: if the original model has 12 heads and the current sub-model's width is 75% of the original, the number of heads in all Transformer blocks becomes 9 during this training phase.
2. The parameter dimensions of the ``Linear`` layers in the ``Feed-Forward Network (FFN)`` are proportionally reduced. For example: if the original FFN layer has a hidden dimension of 3072 and the current sub-model's width is 75% of the original, the FFN's hidden dimension becomes 2304 in all Transformer blocks during this training phase.
Overall Principle
------------
1. **Reordering Parameters and Heads by Importance**: First, parameters and attention heads in the pre-trained model are reordered based on their importance, ensuring critical parameters/heads are prioritized to avoid being pruned during training. Parameter importance is calculated using gradient information from dev data, while head importance is determined by passing an all-ones mask and computing gradients for each head in Multi-Head Attention layers.
2. **Knowledge Distillation Framework**: The original pre-trained model serves as the teacher network. A super-network is defined as the student network, where its largest sub-network shares the same architecture as the teacher. Smaller sub-networks are derived by pruning parameters from the largest network, with all sub-networks sharing parameters during training.
3. **Initialization and Distillation Loss**: The super-network (student) is initialized using reordered parameters from the pre-trained model. Distillation losses are applied to the embedding layer, each transformer block, and the final logits output.
4. **Sub-network Training**: Before processing each batch, a sub-network configuration (currently focusing on width selection) is chosen. Only parameters involved in the current sub-network's computation are updated during backpropagation.
5. **Sub-network Selection**: After training, optimal sub-networks are selected based on both acceleration requirements and accuracy constraints.

.. centered:: Figure: OFA-BERT Architecture Overview
Model Compression with PaddleSlim
--------------------------------
In this example, we also need to train a task-specific BERT model, following the same method as the previous tutorial "Knowledge Distillation from BERT to Bi-LSTM". Here we focus on the model compression process.
1. Define Initial Network
^^^^^^^^^^^^^^^^^^^^^
Define the original BERT-base model and create a dictionary to store the original model parameters. After converting a regular model to a supernet, the original parameters become invalid due to changes in network operators. Therefore, we need to store the original parameters to initialize the supernet.
.. code-block::
model = BertForSequenceClassification.from_pretrained('bert', num_classes=2)
origin_weights = {}
for name, param in model.named_parameters():
origin_weights[name] = param
2. Build Supernet
^^^^^^^^^^^^^^^^
Define the search space and convert the regular network to a supernet based on this search space.
.. code-block::
# Define search space
sp_config = supernet(expand_ratio=[0.25, 0.5, 0.75, 1.0])
# Convert model to supernet
model = Convert(sp_config).convert(model)
paddleslim.nas.ofa.utils.set_state_dict(model, origin_weights)
3. Define Teacher Network
^^^^^^^^^^^^^^^^^^^^^
Construct the teacher network.
.. code-block::
teacher_model = BertForSequenceClassification.from_pretrained('bert', num_classes=2)
4. Configure Distillation Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Required configurations include:
- Teacher model instance
- Layers for distillation: add distillation loss between the teacher and student networks' `Embedding` layers and each `Transformer Block` layer (using default MSE loss)
- `lambda_distill` parameter to scale the overall distillation loss.
.. code-block::
mapping_layers = ['bert.embeddings']
for idx in range(model.bert.config['num_hidden_layers']):
mapping_layers.append('bert.encoder.layers.{}'.format(idx))
default_distill_config = {
'lambda_distill': 0.1,
'teacher_model': teacher_model,
'mapping_layers': mapping_layers,
}
distill_config = DistillConfig(**default_distill_config)
5. Define Once-For-All Model
^^^^^^^^^^^^^^^^^^^^^^^^^
Pass the regular model and distillation configurations to `OFA`.
（Note: The original text ends abruptly. The translation continues the final sentence to maintain grammatical completeness while following all specified formatting and technical requirements.)
Interfaces to automatically add the distillation process and convert the supernetwork training approach to the ``OFA`` training approach.
.. code-block::
ofa_model = paddleslim.nas.ofa.OFA(model, distill_config=distill_config)
6. Compute Neuron and Head Importance and Reorder Parameters Accordingly
^^^^^^^^^^^^
.. code-block::
head_importance, neuron_importance = utils.compute_neuron_head_importance(
'sst-2',
ofa_model.model,
dev_data_loader,
num_layers=model.bert.config['num_hidden_layers'],
num_heads=model.bert.config['num_attention_heads'])
reorder_neuron_head(ofa_model.model, head_importance, neuron_importance)
7. Set the Current Stage of OFA Training
^^^^^^^^^^^^
.. code-block::
ofa_model.set_epoch(epoch)
ofa_model.set_task('width')
8. Configure Network Settings and Start Training
^^^^^^^^^^^^
This example uses DynaBERT's strategy for supernetwork training.
.. code-block::
width_mult_list = [1.0, 0.75, 0.5, 0.25]
lambda_logit = 0.1
for width_mult in width_mult_list:
net_config = paddleslim.nas.ofa.utils.dynabert_config(ofa_model, width_mult)
ofa_model.set_net_config(net_config)
logits, teacher_logits = ofa_model(input_ids, segment_ids, attention_mask=[None, None])
rep_loss = ofa_model.calc_distill_loss()
logit_loss = soft_cross_entropy(logits, teacher_logits.detach())
loss = rep_loss + lambda_logit * logit_loss
loss.backward()
optimizer.step()
lr_scheduler.step()
ofa_model.model.clear_gradients()
**NOTE**
Since calculating head importance requires gradient collection via masking, we need to apply a monkey patch to reimplement the ``forward`` method of the ``BERTModel`` class.
.. code-block::
from paddlenlp.transformers import BertModel
def bert_forward(self,
input_ids,
token_type_ids=None,
position_ids=None,
attention_mask=[None, None]):
wtype = self.pooler.dense.fn.weight.dtype if hasattr(
self.pooler.dense, 'fn') else self.pooler.dense.weight.dtype
if attention_mask[0] is None:
attention_mask[0] = paddle.unsqueeze(
(input_ids == self.pad_token_id).astype(wtype) * -1e9, axis=[1, 2])
embedding_output = self.embeddings(
input_ids=input_ids,
position_ids=position_ids,
token_type_ids=token_type_ids)
encoder_outputs = self.encoder(embedding_output, attention_mask)
sequence_output = encoder_outputs
pooled_output = self.pooler(sequence_output)
return sequence_output, pooled_output
BertModel.forward = bert_forward

# Prompt Learning: Prompt API
With the growth in scale of pre-trained language models, the "pre-train and fine-tune" paradigm has achieved increasingly better performance on downstream NLP tasks. However, this comes with correspondingly higher demands on training data volume and computational resources. To fully utilize the knowledge learned by pre-trained language models while reducing dependency on data and resources, **Prompt Learning** has emerged as a potential new paradigm gaining significant attention, achieving far superior results compared to traditional fine-tuning approaches on few-shot tasks in benchmarks like FewCLUE and SuperGLUE.
The core idea of **Prompt Learning** is to reformulate downstream tasks as masked language modeling (MLM) objectives from the pre-training phase. The implementation approach involves:
1. Using template-defined prompt statements to convert original tasks into predicting masked token positions
2. Establishing mappings between predicted words and true labels through verbalizer definitions
Taking sentiment classification as an example, the differences between the "pre-train and fine-tune" paradigm and the "pre-train and prompt" paradigm (using [PET](https://arxiv.org/abs/2001.07676) as example) are illustrated below:
<div align="center">
<img src=https://user-images.githubusercontent.com/25607475/192727706-0a17b5ef-db6b-46be-894d-0ee315306776.png width=800 height=300 />
</div>
[Fine-tuning Approach] uses `[CLS]`
To perform classification using `ChatGPT`, training a randomly initialized classifier requires sufficient training data to fit.
**[Prompt Learning]** By defining prompt statements and label word mappings, the task is transformed into an MLM task without training new parameters, making it suitable for few-shot scenarios.
The Prompt API provides fundamental modules for implementing such algorithms, supporting rapid implementation of classical algorithms like [PET](https://arxiv.org/abs/2001.07676), [P-Tuning](https://arxiv.org/abs/2103.10385), [WARP](https://aclanthology.org/2021.acl-long.381/), and [RGL](https://aclanthology.org/2022.findings-naacl.81/).

## How to Define Templates
**Templates** add prompt statements to original input text, converting the original task into an MLM task. They can be categorized into discrete and continuous types. The Prompt API provides unified data structures to construct different template types by parsing formatted strings.
### Discrete Templates
Discrete templates `ManualTemplate` directly concatenate prompt statements with original input text. Both share the same word embedding matrix learned from pre-trained models. Suitable for implementing algorithms like PET and RGL.
**Template Keywords and Attributes**
- ``text``: Keywords corresponding to original input text in the dataset, e.g., `text_a`, `text_b`, and `content`.
- ``hard``: Custom prompt text.
- ``mask``: Placeholder for predicted words.
- ``length``: Defines the number of ``mask`` tokens.
- ``sep``: Sentence separator. Use `token_type` attribute to define `token_type_ids` for different sentences (default: same).
- ``options``: Candidate label sequences from dataset dictionaries or files.
- ``add_omask``: Adds `[O-MASK]` before each label for calculating prediction scores of candidate labels. Supports [UniMC](https://arxiv.org/pdf/2210.08590.pdf) algorithm.
- ``add_prompt``
You are a professional NLP technical translator. Translate Chinese to English while:
1. Preserving EXACT formatting (markdown/rst/code)
2. Keeping technical terms in English
3. Maintaining code/math blocks unchanged
4. Using proper academic grammar
5. Keep code block in documents original
6. Keep the link in markdown/rst the same. E.g. [link](#这里) instead of [link](#here)
7. Keep the html tag in markdown/rst the same.
6. Just return the result of Translate. No additional messages.
**Add fixed prompt text for each tag, with tag positions marked by `[OPT]`. Supports implementation of [EFL](https://arxiv.org/pdf/2104.14690.pdf) algorithm.**
**Common Properties of Templates**
- `position`: Defines the starting `position id` for the current field.
- `token_type`: Defines `token type id` for current and subsequent fields.
- `truncate`: Determines whether the current field can be truncated when total prompt and text length exceeds max length. Options: `True` and `False`.
**Template Definition**
```
{'hard': '“'}{'text': 'text_a'}{'hard': '”和“'}{'text': 'text_b'}{'hard': '”之间的逻辑关系是'}{'mask'}
```
Or use simplified definition (equivalent to above by omitting ``hard`` keyword):
```
“{'text': 'text_a'}”和“{'text': 'text_b'}”之间的逻辑关系是{'mask'}
```
```
{'options': './data/label.txt'}{'sep'}下边两句话间的逻辑关系是什么？{'text': 'text_a'}{'sep': None, 'token_type': 1}{'text': 'text_b'}
```
Where `label.txt` is the local file path containing candidate labels (one per line), e.g.
```
neutral
entailment
contradiction
```
**Sample Example**
For natural language inference task, given sample:
```python
sample = {
"text_a": "心里有些生畏,又不知畏惧什么", "text_b": "心里特别开心", "labels": "contradiction"
}
```
After template modification and concatenation, the final input text to model is:
```
“心里有些生畏,又不知畏惧什么”和“心里特别开心”之间的逻辑关系是[MASK]
```
**API Call**
```python
from paddlenlp.prompt import ManualTemplate
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
template = ManualTemplate(prompt="“{'text': 'text_a'}”和“{'text': 'text_b'}”之间的逻辑关系是{'mask'}",
tokenizer=tokenizer,
max_length=512)
input_dict = template(sample)
```
Where initialization parameters are defined as:
- ``prompt``: String defining prompt statement and its combination with input text.
- ``tokenizer``: Pretrained model's tokenizer for text encoding.
- ``max_length``
Define the maximum length of the input model text, including the prompt section.
**Usage Tips**
The impact of different template definitions on results is significant. Generally, the more natural and fluent the concatenated prompt statements are with the original input text, the better the model performance. In practice, different templates should be analyzed and tried for different tasks to achieve optimal results.
### Continuous Template
The challenge in using discrete templates lies in the requirement of substantial experience and linguistic expertise to design good prompt statements. To address this, the continuous template `SoftTemplate` attempts to use a set of continuous prompt vectors as templates, eliminating the need for manual prompt design during model training. Of course, `SoftTemplate` also supports initializing prompt vectors with human-crafted prompts. The key difference from discrete templates is that the continuous prompt vectors and the input text's word embedding matrix are not shared; they are updated separately during training. This can be used to implement algorithms like P-Tuning.
Additionally, continuous templates support hybrid template definitions, i.e., concatenating both discrete prompts and continuous prompt vectors with the original input.
**Template Keywords**
- ``text``: Keywords corresponding to original input texts in the dataset, e.g., `text_a` and `text_b`.
- ``hard``: User-defined text prompts.
- ``mask``: Placeholder for tokens to be predicted.
- ``sep``: Sentence separator token. Different sentences' `token_type_ids` should be defined using the `token_type` attribute; they are identical by default.
- ``soft``: Represents continuous prompts. If the value is ``None``, prompt vectors are randomly initialized; if a text value is provided, the corresponding pretrained word embeddings are used for initialization.
- ``length``: Defines the number of ``soft tokens``. If the defined text length is less than this value, the excess portion is randomly initialized.
- ``encoder``: Defines the encoder type for `soft tokens`, options include `lstm` and `mlp`. Default is `None` (no encoder used).
- ``hidden_size``: Defines the hidden layer dimension of the encoder. Defaults to the same dimension as the pretrained word embeddings.
- ``options``: Candidate label sequences from the dataset dictionary or files.
- ``add_omask``: Adds `[O-MASK]` before each label for calculating prediction scores of candidate labels. Supports implementation of the [UniMC](https://arxiv.org/pdf/2210.08590.pdf) algorithm.
- ``add_prompt``: Appends fixed prompt text to each label, with label positions marked by `[OPT]`. Supports implementation of the [EFL](https://arxiv.org/pdf/2104.14690.pdf) algorithm.
**General Template Attributes**
- `position`: Defines the starting `position id` for the current field.
- `token_type`: Defines the `token type id` for the current and subsequent fields.
- `truncate`: Determines whether the current field can be truncated when the total length of prompts and text exceeds the maximum length. Options: `True` or `False`.
**Template Definitions**
- Define a continuous prompt of length 1 with random initialization:
```python
"{'soft'}{'text': 'text_a'}{'sep': None, 'token_type': 1}{'text': 'text_b'}"
```
- Define a continuous prompt of length 10 with random initialization and `mlp` encoder:
```python
"{'text': 'text_a'}{'sep'}{'text': 'text_b'}{'soft': None, 'length':10, 'encoder': 'mlp'}{'mask'}"
```
- Define a continuous prompt of length 15, initialize the first three soft tokens with `Please determine`, and randomly initialize the rest, with the encoder being a two-layer LSTM with hidden dimension 100:
```python
"{'text': 'text_a'}{'sep'}{'text': 'text_b'}{'soft': 'Please determine:', 'length': 15, 'encoder': 'lstm', 'hidden_size': 100}{'mask'}"
```
- Define a continuous prompt of length 15, initialized with the pretrained word vectors of `"Please determine the logical relationship between these two sentences:"` one by one:
```python
"{'text': 'text_a'}{'sep'}{'text': 'text_b'}{'soft': 'Please determine the logical relationship between these two sentences:'}{'mask'}"
```
- Define a hybrid template, where the `soft` keyword corresponds to one set of vectors and the `hard` keyword corresponds to another set of distinct vectors:
```python
"{'soft': 'Natural Language Inference Task:'}{'text': 'text_a'}{'sep'}{'text': 'text_b'} The logical relationship between these two sentences is {'mask'}"
```
**API Invocation**
```python
from paddlenlp.prompt import SoftTemplate
from paddlenlp.transformers import AutoTokenizer, AutoModelForMaskedLM
model = AutoModelForMaskedLM.from_pretrained("ernie-3.0-base-zh")
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
template = SoftTemplate(prompt="{'text': 'text_a'}{'sep'}{'text': 'text_b'}{'soft': 'Please determine the logical relationship between these two sentences:'}{'mask'}",
tokenizer=tokenizer,
max_length=512,
word_embeddings=model.get_input_embeddings())
```
The initialization parameters are defined as follows:
- ``prompt``: String defining the prompt statements for continuous templates, initialization methods, and composition with input text.
- ``tokenizer``: Pretrained model tokenizer for text encoding.
- ``max_seq_length``: Defines the maximum sequence length of model input text, including the prompt section.
- ``word_embeddings``: Word embeddings from the pretrained language model, used for continuous prompt vector initialization.
- ``soft_embeddings``
Continuous prompt vector matrix, which can be used for sharing continuous parameters between different templates. When set, it will override the default continuous vector matrix.
**Usage Tips**
- For classification tasks, the recommended length for continuous prompts is typically 10-20.
- For randomly initialized continuous prompt vectors, parameters are usually updated with a larger learning rate compared to fine-tuning pre-trained models.
- Similar to discrete templates, continuous templates are also sensitive to initialization. Using custom prompt statements as initialization parameters for continuous prompt vectors often yields better results than random initialization.
- The `prompt_encoder` refers to strategies from existing papers, used to model sequential relationships between different continuous prompt vectors.
### Prefix Continuous Template
`PrefixTemplate` also uses continuous vectors as prompts. Unlike `SoftTemplate`, the prompt vectors in this template not only operate at the input layer but also have corresponding prompt vectors at each layer. This can be used to implement algorithms like P-Tuning.
**Template Keywords**
- ``text``: Keywords corresponding to original input text in the dataset, e.g., `text_a` and `text_b`.
- ``hard``: Custom textual prompt statements.
- ``mask``: Placeholder for the word to be predicted.
- ``sep``: Sentence separator. Different sentences' `token_type_ids` should be defined using the `token_type` attribute, which is the same by default.
- ``prefix`` represents continuous prompts. This field **must** be placed first in the template. If the value is ``None``, prompt vectors are randomly initialized; if the value is text, the corresponding pre-trained word vectors are used to initialize the prompt vectors.
- ``length``: Defines the number of ``soft tokens``. If the defined text length is less than this value, the excess part will be randomly initialized.
- ``encoder``: Defines the encoder type for `soft tokens`, options include `lstm` and `mlp`. Default is `None` (no encoder used).
- ``hidden_size``: Defines the hidden layer dimension of the encoder. Default is the same as the pre-trained word vector dimension.
- ``options``: Candidate label sequences from the dataset dictionary or files.
- ``add_omask``: Adds `[O-MASK]` before each label for computing prediction scores of candidate labels. Supports implementation of the [UniMC](https://arxiv.org/pdf/2210.08590.pdf) algorithm.
- ``add_prompt``: Appends fixed prompt text to each label, with label positions marked by `[OPT]`. Supports implementation of the [EFL](https://arxiv.org/pdf/2104.14690.pdf) algorithm.
**General Template Attributes**
- `position`: Defines the starting `position id` for the current field.
- `token_type`: Defines the `token type id` for the current field and subsequent fields.
- `truncate`: Determines whether the current field can be truncated when the total length of prompts and text exceeds the maximum length. Options are `True` or `False`.
**Template Definition**
- Define a continuous prompt of length 15 with random initialization:
```python
"{'prefix': 'news category', 'length': 10, 'encoder': 'lstm'}{'text': 'text_a'}"
```
- Define a hybrid template where the `prefix` keyword corresponds to one set of prompt vectors and `hard` corresponds to another distinct set:
```python
"{'prefix': None, 'length': 15, 'encoder': 'mlp'}{'hard': 'This is a text: '}{'text': 'text_a'}"
```
```python
"{'prefix': 'Natural Language Inference Task:', 'encoder': 'mlp'}{'text': 'text_a'}{'sep'}{'text': 'text_b'} The logical relationship between these two sentences is {'mask'}"
```
**API Call**
```python
from paddlenlp.prompt import PrefixTemplate
from paddlenlp.transformers import AutoTokenizer, AutoModelForMaskedLM
model = AutoModelForMaskedLM.from_pretrained("ernie-3.0-base-zh")
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
template = PrefixTemplate(prompt="{'prefix': 'Task Description'}{'text': 'text_a'}{'mask'}",
tokenizer=tokenizer,
max_length=512,
model=model,
prefix_dropout=0.1)
```
The initialization parameters are defined as follows:
- ``prompt``: Defines the prompt statement, initialization, and text composition method for the continuous template.
- ``tokenizer``: Pretrained model's tokenizer for text encoding.
- ``max_length``: Defines the maximum length of input text to the model, including the prompt section.
- ``model``: Pretrained language model for continuous prompt vector initialization and generating corresponding prompt vectors per layer based on model architecture.
- ``prefix_dropout``: Dropout probability for continuous prompt vectors, used for regularization.
### Quick Template Definition
PaddleNLP provides the ``AutoTemplate`` API for rapid definition of simplified discrete templates, and can automatically switch between ManualTemplate, SoftTemplate, and PrefixTemplate based on complete template strings.
**Template Definition**
- Quickly define discrete text prompts. For example:
```python
"What emotion does this article express?"
```
is equivalent to:
```python
"{'text': 'text_a'}{'hard': 'What emotion does this article express?'}{'mask'}"
```
- When input is a complete template string, the parsed template will be consistent with the descriptions in [Discrete Templates](#discrete-templates) and [Continuous Templates](#continuous-templates).
```python
from paddlenlp.prompt import AutoTemplate
from paddlenlp.transformers import AutoTokenizer, AutoModelForMaskedLM
model = AutoModelForMaskedLM.from_pretrained("ernie-3.0-base-zh")
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
# Discrete template, returns ManualTemplate instance
template = AutoTemplate.create_from(prompt="What emotion does this sentence express?",
tokenizer=tokenizer,
max_length=512)
template = AutoTemplate.create_from(prompt="What emotion does this sentence express? {'text': 'text_a'}{'mask'}",
tokenizer=tokenizer,
max_length=512)
# Continuous template, returns SoftTemplate instance
template = AutoTemplate.create_from(prompt="{'text': 'text_a'}{'sep'}{'text': 'text_b'}{'soft': 'Please determine the logical relationship between these two sentences:'}{'mask'}",
tokenizer=tokenizer,
max_length=512,
model=model)
# Prefix continuous template, returns PrefixTemplate instance
template = AutoTemplate.create_from(prompt="{'prefix': None, 'encoder': 'mlp', 'hidden_size': 50}{'text': 'text_a'}",
tokenizer=tokenizer,
max_length=512,
model=model)
```
The initialization parameters are defined as follows:
- ``prompt``: Defines discrete/continuous prompts, initialization, and combination with input text.
- ``tokenizer``: Tokenizer of the pre-trained model, used for text encoding.
- ``max_length``: Defines the maximum length of input text to the model, including the prompt section.
- ``model``
## How to Define Label Word Mapping
**Label Word Mapping** (Verbalizer) is an optional yet crucial module in prompt learning, establishing the mapping between predicted words and labels. It transforms the label prediction task from the traditional "pre-train fine-tune" paradigm into predicting masked words in templates, thereby unifying downstream tasks as pre-training objectives. The framework currently supports discrete label word mapping and continuous label word mapping via the [Word-level Adversarial ReProgramming (WARP)](https://aclanthology.org/2021.acl-long.381/) method.
For example, in a sentiment binary classification task:
- **Fine-tuning Approach**: Dataset labels are ``negative`` and ``positive``, mapped to ``0`` and ``1`` respectively.
- **Prompt Learning**: Uses the following label word mapping to bridge original labels and predicted words.
```python
{'negative': '不', 'positive': '很'}
```
Specifically, for the template ``{'text':'text_a'}这句话表示我{'mask'}满意。``, we use the mapping ``{'negative': '不', 'positive': '很'}`` to map label ``negative`` to ``不`` and label ``positive`` to ``很``. This means: for positive sentiment texts, the prediction should be ``...这句话表示我很满意。``; for negative sentiment texts, the prediction should be ``...这句话表示我不满意。``.
### Discrete Label Word Mapping
``ManualVerbalizer`` supports constructing label word mappings for ``{'mask'}`` positions. A single label can correspond to multiple words of varying lengths, directly applied to the ``AutoMaskedLM`` architecture. When a label's corresponding word exceeds length 1, the average is taken by default; when multiple `{'mask'}` tokens exist, it equivalently handles them as single `{mask}`.
**API Usage**
```python
from paddlenlp.prompt import ManualVerbalizer
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
verbalizer = ManualVerbalizer(tokenizer=tokenizer,
label_words={'negative': '不', 'positive': '很'})
```
Initialization parameters:
- ``label_words``: Dictionary mapping original labels to predicted words.
- ``tokenizer``: Pretrained model's tokenizer for word encoding.
``MaskedLMVerbalizer`` also supports label word mapping for ``{'mask'}`` positions. The mapped words must align with the number of `{'mask'}` tokens in the template. When multiple words are defined for the same label, only the first takes effect. The custom ``compute_metric`` function should call ``verbalizer.aggregate_multiple_mask`` to merge multiple `{'mask'}` positions before evaluation (product aggregation by default).
**API Usage**
```python
from paddlenlp.prompt import MaskedLMVerbalizer
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
verbalizer = MaskedLMVerbalizer(tokenizer=tokenizer,
label_words={'negative': 'not', 'positive': 'very'})
```
The initialization parameters are defined as follows:
- ``label_words``: A dictionary mapping original labels to prediction words.
- ``tokenizer``: The tokenizer from the pre-trained model, used for encoding prediction words.
### Continuous Label Word Mapping
The label word mapping classifier ``SoftVerbalizer`` modifies the original ``AutoMaskedLM`` model architecture by replacing the last "hidden layer-vocabulary" mapping with a "hidden layer-label" mapping. The initialization parameters of this layer are determined by the word vectors from the label word mapping. If the prediction word length exceeds ``1``, the average of word vectors is used for initialization. Currently supported pre-trained models include ``ErnieForMaskedLM``, ``BertForMaskedLM``, ``AlbertForMaskedLM``, and ``RobertaForMaskedLM``. This can be used to implement the WARP algorithm.
**API Call**
```python
from paddlenlp.prompt import SoftVerbalizer
from paddlenlp.transformers import AutoTokenizer, AutoModelForMaskedLM
model = AutoModelForMaskedLM.from_pretrained("ernie-3.0-base-zh")
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
verbalizer = SoftVerbalizer(label_words={'negative': 'angry', 'positive': 'happy'},
tokenizer=tokenizer,
model=model)
```
- ``label_words``: A dictionary mapping original labels to prediction words.
- ``tokenizer``: The tokenizer from the pre-trained model, used for encoding prediction words.
- ``model``: The pre-trained language model used to retrieve pre-trained word vectors for modifying and initializing the "hidden layer-label" network.
## Quick Start Training
This section explains how to use ``PromptTrainer`` to quickly set up a prompt training workflow.
### Data Preparation
The dataset is encapsulated as ``MapDataset`` type. Each data entry is formatted as a dictionary, where the dictionary keys correspond to the values defined in the template's `text`, and the `labels` keyword is uniformly used to represent sample labels.
For example, a data sample from the text semantic similarity BUSTM dataset:
```python
from paddlenlp.datasets import MapDataset
data_ds = MapDataset([
{'id': 3, 'sentence1': '你晚上吃了什么', 'sentence2': '你晚上吃啥了', 'label': 1},
{'id': 4, 'sentence1': '我想打开滴滴叫的士', 'sentence2': '你叫小欧吗', 'label': 0},
{'id': 5, 'sentence1': '女孩子到底是不是你', 'sentence2': '你不是女孩子吗', 'label': 1}
])
def convert_label_keyword(input_dict):
input_dict["labels"] = input_dict.pop("label")
return input_dict
data_ds = data_ds.map(convert_label_keyword)
```
### Pre-trained Parameter Preparation
If using label word mapping, load pre-trained parameters with ``AutoModelForMaskedLM`` and ``AutoTokenizer``. If not using label word mapping, you can replace ``AutoModelForMaskedLM`` with the corresponding model for the task.
```python
from paddlenlp.transformers import AutoTokenizer, AutoModelForMaskedLM
model = AutoModelForMaskedLM.from_pretrained("ernie-3.0-base-zh")
tokenizer = AutoTokenizer.from_pretrained("ernie-3.0-base-zh")
```
### Defining the Prompt Learning Model
For text classification tasks, we encapsulate template preprocessing and label word mapping into the prompt learning model ``PromptModelForSequenceClassification``.
```python
from paddlenlp.prompt import AutoTemplate
from paddlenlp.prompt import ManualVerbalizer
from paddlenlp.prompt import PromptModelForSequenceClassification
# Define template
template = AutoTemplate.create_from(prompt="{'text': 'text_a'} and {'text': 'text_b'} are talking about {'mask'} same thing.",
tokenizer=tokenizer,
max_length=512)
# Define label word mapping
verbalizer = ManualVerbalizer(label_words={0: 'not', 1: 'related'},
tokenizer=tokenizer)
# Define prompt-based sequence classification model
prompt_model = PromptModelForSequenceClassification(model,
template,
verbalizer,
freeze_plm=False,
freeze_dropout=False)
```
The initialization parameters for the prompt model are as follows:
- ``model`` : Pre-trained model instance, supporting ``AutoModelForMaskedLM`` and ``AutoModelForSequenceClassification``.
- ``template`` : Template instance.
- ``verbalizer`` : Label word mapping instance. When set to ``None``, label word mapping is not used, model output and loss calculation are defined by the ``model`` type.
- ``freeze_plm`` : Freeze pre-trained model parameters during training, default is `False`. For lightweight pre-trained models, the default value is recommended.
- ``freeze_dropout`` : Freeze pre-trained model parameters and disable ``dropout`` during training. When ``freeze_dropout=True``, ``freeze_plm`` also becomes ``True``.
### Training with PromptTrainer
``PromptTrainer`` inherits from ``Trainer``, encapsulating data processing, model training/evaluation, and training strategies for rapid setup of training workflow.
**Configuring Training Parameters**
``PromptTuningArguments`` inherits from ``TrainingArguments``, containing main training parameters for prompt learning. For ``TrainingArguments`` parameters, see
`Trainer API Documentation <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/docs/trainer.md>`_. For other parameters, please refer to [Prompt Trainer Parameter List](#PromptTrainer-Parameter-List). It is recommended to use **command line** for parameter configuration, i.e.
```shell
python xxx.py --output_dir xxx --learning_rate xxx
```
In addition to training parameters, custom parameters related to data and models need to be defined. Finally, use ``PdArgumentParser`` to output the parameters.
```python
from dataclasses import dataclass, field
from paddlenlp.trainer import PdArgumentParser
from paddlenlp.prompt import PromptTuningArguments
@dataclass
class DataArguments:
data_path : str = field(default="./data", metadata={"help": "The path to dataset."})
parser = PdArgumentParser((DataArguments, PromptTuningArguments))
data_args, training_args = parser.parse_args_into_dataclasses(
args=["--output_dir", "./", "--do_train", "True"], look_for_args_file=False)
```
**Initialization and Training**
In addition to the above preparations, loss function and evaluation metrics need to be defined.
```python
import paddle
from paddle.metric import Accuracy
from paddlenlp.prompt import PromptTrainer
# Loss function
criterion = paddle.nn.CrossEntropyLoss()
# Evaluation function
def compute_metrics(eval_preds):
metric = Accuracy()
correct = metric.compute(paddle.to_tensor(eval_preds.predictions),
paddle.to_tensor(eval_preds.label_ids))
metric.update(correct)
acc = metric.accumulate()
return {"accuracy": acc}
# Initialization
trainer = PromptTrainer(model=prompt_model,
tokenizer=tokenizer,
args=training_args,
criterion=criterion,
train_dataset=data_ds,
eval_dataset=None,
callbacks=None,
compute_metrics=compute_metrics)
# Training the model
if training_args.do_train:
train_result = trainer.train(resume_from_checkpoint=None)
metrics = train_result.metrics
trainer.save_model()
trainer.log_metrics("train", metrics)
trainer.save_metrics("train", metrics)
trainer.save_state()
```

==============
Creating :class:`DatasetBuilder`
==============
Dataset contributions are achieved by defining a subclass of :class:`DatasetBuilder`. A qualified :class:`DatasetBuilder` needs to follow certain protocols and specifications.
Let's take :obj:`LCQMC` as an example to understand the typical methods and parameters required in a :class:`DatasetBuilder`.
Member Variables
---------------
.. code-block::
from paddle.dataset.common import md5file
from paddle.utils.download import get_path_from_url
from paddlenlp.utils.env import DATA_HOME
class LCQMC(DatasetBuilder):
"""
LCQMC: A Large-scale Chinese Question Matching Corpus
More information please refer to `https://www.aclweb.org/anthology/C18-1166/`
"""
lazy = False
URL = "https://bj.bcebos.com/paddlehub-dataset/lcqmc.tar.gz"
MD5 = "62a7ba36f786a82ae59bbde0b0a9af0c"
META_INFO = collections.namedtuple('META_INFO', ('file', 'md5'))
SPLITS = {
'train': META_INFO(
os.path.join('lcqmc', 'train.tsv'),
'2193c022439b038ac12c0ae918b211a1'),
'dev': META_INFO(
os.path.join('lcqmc', 'dev.tsv'),
'c5dcba253cb4105d914964fd8b3c0e94'),
'test': META_INFO(
os.path.join('lcqmc', 'test.tsv'),
'8f4b71e15e67696cc9e112a459ec42bd'),
}
First, the contributed dataset needs to inherit from the :class:`paddlenlp.datasets.DatasetBuilder` class, with the class name in camel case format. Then you should add a docstring briefly describing the dataset's origin and other information. The following member variables need to be defined:
- :attr:`lazy`: The default dataset type. :obj:`False` corresponds to :class:`MapDataset`, :obj:`True` corresponds to :class:`IterDataset`.
- :attr:`URL
- :attr:`URL`: The download URL for the dataset archive, must provide a valid and stable link. If the dataset is not archived, this may be omitted.
- :attr:`MD5`: MD5 checksum of the dataset archive for file validation. If the dataset is not archived, this may be omitted.
- :attr:`META_INFO`: The format of dataset split information.
- :attr:`SPLITS`: Split information of the dataset, containing file locations, filenames, MD5 values, etc. after decompression. For non-archived datasets, download URLs are typically provided here. May also include parameters like file reading configurations.
Additionally, some datasets may require other member variables like :attr:`VOCAB_INFO` (refer to `iwslt15.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/iwslt15.py>`__). Member variables may have different formats. Contributors can adjust accordingly based on actual requirements.
.. note::
- If the contributed dataset has no subsets, the :class:`DatasetBuilder` **must include** the :attr:`SPLITS` member variable, which must be a dictionary with keys corresponding to the dataset's splits.
- If the contributed dataset contains subsets, the :class:`DatasetBuilder` **must include** the :attr:`BUILDER_CONFIGS` member variable. This must be a dictionary with keys corresponding to the subset's :attr:`name`. The values should be dictionaries containing split information for the subset, with keys being `splits`. For specific formats, refer to `glue.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/glue.py>`__.
:func:`_get_data` Method
------------------------
.. code-block::
def _get_data(self, mode, **kwargs):
''' Check and download Dataset '''
default_root = os.path.join(DATA_HOME, self.__class__.__name__)
filename, data_hash = self.SPLITS[mode]
fullname = os.path.join(default_root, filename)
if not os.path.exists(fullname) or (data_hash and
not md5file(fullname) == data_hash):
get_path_from_url(self.URL, default_root, self.MD5)
return fullname
The :func:`_get_data` method locates the specific dataset file based on the input :attr:`mode` and split information. It first performs MD5 checksum validation on local files. If validation fails, it calls :func:`
`paddle.utils.download.get_path_from_url` method downloads and verifies dataset files, finally returns the local path of dataset file.
:func:`_read` method
-----------------------
.. code-block::
def _read(self, filename):
"""Reads data."""
with open(filename, 'r', encoding='utf-8') as f:
head = None
for line in f:
data = line.strip().split("\t")
if not head:
head = data
else:
query, title, label = data
yield {"query": query, "title": title, "label": label}
The :func:`_read` method reads data from given file path. This method must be a generator to ensure :class:`DatasetBuilder` can construct both :class:`MapDataset` and :class:`IterDataset`. When different splits require distinct data reading approaches, this method should additionally support :attr:`split` parameter and handle different split configurations.
.. note::
- Each example provided by this method should be a :class:`Dictionary` object.
- :class:`DatasetBuilder` provides label-to-id conversion during Dataset generation. To use this feature, users must set the label key in examples as **"label"** or **"labels"**, and properly implement :func:`get_labels` method in the class.
:func:`get_labels` method
-----------------------
.. code-block::
def get_labels(self):
"""
Return labels of the LCQMC object.
"""
return ["0", "1"]
The :func:`get_labels` method returns a list containing all labels in the dataset. This is used to convert class labels to ids, and this list will be passed as an instance variable to the generated dataset.
:func:`get_vocab` method
-----------------------
If the dataset provides vocabulary files, the :func:`get_vocab` method and :attr:`VOCAB_INFO` variable need to be added.
This method returns a :class:`Dictionary` object containing dataset vocabulary information based on :attr:`VOCAB_INFO`, which is passed as an instance variable to the generated dataset. Used to initialize :class:`paddlenlp.data.Vocab` object during training. Refer to official implementation for method details.
iwslt15.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/iwslt15.py>`__
.. note::
- When contributing a dataset, the :func:`get_labels` and :func:`get_vocab` methods are optional, depending on the specific dataset content. The :func:`_read` and :func:`_get_data` methods are **required**.
- If you do not wish to perform an md5 check during data retrieval, you may omit the relevant member variables and validation code.

========================
Sharing Your Dataset
========================
In addition to using built-in datasets in PaddleNLP, we also encourage users to contribute their own datasets to PaddleNLP.
Below we detail the workflow for contributing a dataset:
Environment Setup
---------------
#. Writing and testing PaddleNLP code requires Python 3.6+ and the latest version of PaddlePaddle. Please ensure these dependencies are properly installed.
#. Click the Fork button on PaddleNLP's GitHub page to create a copy of the PaddleNLP repo under your GitHub account.
#. Clone your forked repo locally and add the official repo as a remote.
.. code-block::
git clone https://github.com/USERNAME/PaddleNLP
cd PaddleNLP
git remote add upstream https://github.com/PaddlePaddle/PaddleNLP.git
#. Install the pre-commit hook, which helps format source code and automatically check for issues before submission. PRs that fail hook checks **cannot** be merged into PaddleNLP.
.. code-block::
pip install pre-commit
pre-commit install
Adding a :class:`DatasetBuilder`
----------------------------------
#. Create a new local branch, typically branched from develop.
.. code-block::
git checkout -b my-new-dataset
#. Navigate to the `PaddleNLP/paddlenlp/datasets/` directory in your local repo - all dataset code is stored here.
.. code-block::
cd paddlenlp/datasets
#. Determine a `name` for your dataset (e.g., `squad`, `chnsenticorp`). This `name` will be used when loading your dataset.
.. note::
- To facilitate usage, ensure the `name` is **concise and semantically meaningful**.
- The dataset `name` should follow snake_case convention.
#. Create a Python file named after the dataset `name` (e.g., `squad.py`) in this directory. Implement your dataset's :class:`DatasetBuilder` class in this file.
Refer to the tutorial :doc:`How to Write a DatasetBuilder <./how_to_write_a_DatasetBuilder>` for detailed guidelines on implementing :class:`DatasetBuilder`.
We also recommend referencing existing :class:`DatasetBuilder` implementations. The following examples may be helpful:
- `squad.py`
`iwslt15.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/iwslt15.py>`__ Translation dataset containing vocabulary files.
- `glue.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/glue.py>`__ GLUE dataset containing multiple sub-datasets, file format is TSV.
- `squad.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/squad.py>`__ Reading comprehension dataset, file format is JSON.
- `imdb.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/imdb.py>`__ IMDB dataset, each split contains multiple files.
- `ptb.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/ptb.py>`__ Corpus dataset.
- `msra_ner.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/datasets/msra_ner.py>`__ Sequence labeling dataset.
#. After development, you can use :attr:`load_dataset` to test whether the splits in your created dataset can be correctly identified. You can also use :attr:`
Check if the dataset reading format meets your expectations:
.. code-block::
from paddlenlp.datasets import load_dataset
ds = load_dataset('your_dataset_name', splits='your_split')
print(ds[0])
Submit Your Work
---------------
#. When you confirm the dataset code is ready, commit your changes locally:
.. code-block::
git add PaddleNLP/paddlenlp/datasets/your_dataset_name.py
git commit
#. Before submitting, it's recommended to fetch the latest upstream code and update current branch:
.. code-block::
git fetch upstream
git pull upstream develop
#. Push local changes to GitHub and submit a Pull Request to PaddleNLP:
.. code-block::
git push origin my-new-dataset
The above is the complete process for contributing datasets to PaddleNLP. We will review your PR promptly and provide feedback if needed. If everything looks good, we will merge it into the PaddleNLP repo, making your dataset available to others.
If you have any questions about contributing datasets, feel free to join our official QQ technical group: 973379845. We'll address your inquiries promptly.

Precision Alignment
==========================================
1. Overview
==========================================
1.1 Background
------------------------------------------
Model precision alignment is crucial for subsequent work, ensuring that the same model produces stable and consistent output results under identical environments and parameter configurations. This provides a solid foundation for subsequent data analysis, decision-making, and system optimization.
1.2 Prerequisites
------------------------------------------
Based on precision alignment acceptance criteria, the following preparations are recommended:
* Prepare training/validation datasets for model training and evaluation.
* Prepare PyTorch model architecture as the baseline for model precision.
* Prepare validation hardware: For fp16 model parameters, use V100, A100, etc. For bf16 parameters, use A100 or similar compute cards.
2. Workflow
==========================================
The overall workflow includes model structure alignment, small dataset preparation, initial forward alignment, loss function alignment, optimizer alignment, learning rate alignment, regularization strategy alignment, initial backward alignment, training data alignment, and training alignment. For large models using parallel strategies, additional steps include parallel model structure alignment, parallel forward alignment, and parallel backward alignment.
2.1 Process Overview
------------------------------------------
The overall workflow for model precision validation is shown below:

3. Model Alignment Process
==========================================
3.1 Model Structure Alignment
------------------------------------------
Three main steps for model structure alignment:
* Network structure code conversion
* Weight conversion
* Model architecture validation
3.1.1 Network Structure Code Conversion
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
【Basic Process】
PyTorch APIs are generally similar to PaddlePaddle APIs. Refer to the `PyTorch Latest Release vs Paddle Develop API Mapping Table`_ for manual conversion of some network code.
.. _PyTorch Latest Release vs Paddle Develop API Mapping Table: https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/model_convert/convert_from_pytorch/pytorch_api_mapping_cn.html
【Automatic Code Conversion Tool】
`PaConvert Automatic Code Conversion Tool`
_ Can automatically convert code trained or inferred by other deep learning frameworks into PaddlePaddle code, facilitating quick and automated model code migration.
Currently only supports automatic conversion of PyTorch code. Support for other deep learning frameworks will be added later.
During conversion, we try to maintain the original code style and structure, converting API interfaces from other frameworks to PaddlePaddle APIs.
.. _PaConvert Code Auto-Conversion Tool : https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/model_convert/convert_from_pytorch/paconvert_introduction_cn.html
【Large Model Network Structure Examples】
* Llama: https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/transformers/llama/modeling.py
* Qwen2: https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/transformers/qwen2/modeling.py

3.1.3 Model Network Correctness Verification
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
【Basic Process】
1. Define PyTorch model, load weights, fix seed, generate random numbers based on numpy, convert to tensor processable by PyTorch, feed into network, obtain output.
2. Define PaddlePaddle model, load weights, fix seed, generate random numbers based on numpy, convert to tensor processable by PaddlePaddle, feed into network, obtain output.
3. Check diff; if below threshold, verification is successful.
【Example Code】
.. code-block:: python
:linenos:
import numpy as np
import paddle
import torch
from transformers import Qwen2Config as Qwen2Config_hf
from transformers import Qwen2ForCausalLM as Qwen2ForCausalLM_hf
from paddlenlp.transformers import Qwen2Config, Qwen2ForCausalLM
def eval_model_convert():
paddle_input_ids = paddle.to_tensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
torch_input_ids = torch.LongTensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
# paddle model
paddle_ckpt_path = "Qwen/Qwen2-0.5B"
config_paddle = Qwen2Config.from_pretrained(paddle_ckpt_path)
model_paddle = Qwen2ForCausalLM.from_pretrained(paddle_ckpt_path, config=config_paddle, dtype="float32")
# torch model
torch_ckpt_path = "/root/.cache/modelscope/hub/Qwen/Qwen2-0___5B"
config_torch = Qwen2Config_hf.from_pretrained(torch_ckpt_path, trust_remote_code=True)
config_torch.dtype = "float32"
model_torch = Qwen2ForCausalLM_hf.from_pretrained(torch_ckpt_path, config=config_torch, trust_remote_code=True)
model_paddle.eval()
model_torch.eval()
out_paddle = model_paddle(paddle_input_ids)[0]
out_torch = model_torch(torch_input_ids, return_dict=False)[0]
assert np.allclose(out_paddle.numpy(), out_torch.detach().numpy(), rtol=1e-5, atol=1e-3)
eval_model_convert()
【Notes】
* When verifying forward alignment, call model.eval() to disable randomness in network components like BatchNorm and Dropout.
* For reproducibility, fix random seeds if random numbers are involved.
* Output diff can be calculated using np.max(np.abs(o1 - o2)). Generally, if diff <1e-5, forward pass is considered correct. If output diff is large, use binary search to locate the problematic operation.
* Set environment variables to avoid operator randomness:
.. code-block:: shell
:linenos:
# General environment variables
export NVIDIA_TF32_OVERRIDE=0
export FLAGS_embedding_deterministic=1
export FLAGS_cudnn_deterministic=1
# Distributed training environment variables
export Flags_mp_aysnc_allreduce=1
export Flags_skip_mp_c_identity=1
export FLAGS_shard_norm_align_dp=0
export FLAGS_shard_use_reduce=1
export FLAGS_sync_before_allreduce=1
3.1.4 Distributed Network Alignment
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
【Basic Process】
The basic process is similar to section 3.1.3. Additionally, during model initialization, create a distributed environment and use paddle.distributed.launch to start training. Example command:
.. code-block:: shell
:linenos:
python -m paddle.distributed.launch --devices 0,1 compare_torch_with_paddle.py
【Example Code】
.. code-block:: python
:linenos:
import numpy as np
import paddle
import torch
from padiff import auto_diff
from transformers import Qwen2Config as Qwen2Config_hf
from transformers import Qwen2ForCausalLM as Qwen2ForCausalLM_hf

from paddlenlp.transformers import Qwen2Config, Qwen2ForCausalLM
def eval_model_convert_parallel(mp_degree=1):
paddle_input_ids = paddle.to_tensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
torch_input_ids = torch.LongTensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
strategy = fleet.DistributedStrategy()
strategy.hybrid_configs = {
"dp_degree": 1,
"mp_degree": mp_degree,
"pp_degree": 1,
"sharding_degree": 1,
}
fleet.init(is_collective=True, strategy=strategy)
hcg = fleet.get_hybrid_communicate_group()
# paddle model
paddle_ckpt_path = "Qwen/Qwen2-0.5B"
config_paddle = Qwen2Config.from_pretrained(paddle_ckpt_path)
config_paddle.tensor_parallel_degree = hcg.get_model_parallel_world_size()
config_paddle.tensor_parallel_rank = hcg.get_model_parallel_rank()
config_paddle.tensor_parallel_output = False
model_paddle = Qwen2ForCausalLM.from_pretrained(paddle_ckpt_path, config=config_paddle, dtype="float32")
# torch model
torch_ckpt_path = "/root/.cache/modelscope/hub/Qwen/Qwen2-0___5B"
config_torch = Qwen2Config_hf.from_pretrained(torch_ckpt_path, trust_remote_code=True)
config_torch.dtype = "float32"
model_torch = Qwen2ForCausalLM_hf.from_pretrained(torch_ckpt_path, config=config_torch, trust_remote_code=True)
model_paddle.eval()
model_torch.eval()
# Manual verification
out_paddle = model_paddle(paddle_input_ids)[0]
out_torch = model_torch(torch_input_ids, return_dict=False)[0]
assert np.allclose(out_paddle.numpy(), out_torch.detach().numpy(), rtol=1e-5, atol=1e-4)
eval_model_convert_parallel(mp_degree=2)
【Notes】
* Set environment variables to avoid operator randomness:
.. code-block:: shell
:linenos:
# General environment variables
export NVIDIA_TF32_OVERRIDE=0
export FLAGS_embedding_deterministic=1
export FLAGS_cudnn_deterministic=1
# Distributed training environment variables
export Flags_mp_aysnc_allreduce=1
export Flags_skip_mp_c_identity=1
export FLAGS_shard_norm_align_dp=0
export FLAGS_shard_use_reduce=1
export FLAGS_sync_before_allreduce=1
3.2 Forward & Backward Alignment - Alignment Tool Verification
------------------------------------------
【Basic Process】
Instead of manual verification, use automated tool PaDiff for alignment. PaDiff is a model precision alignment tool between PaddlePaddle and PyTorch. It takes Paddle or Torch models, aligns intermediate training results and final weights, and reports where the first precision diff occurs.
PaDiff: https://github.com/PaddlePaddle/PaDiff
【Usage】
.. code-block:: python

def eval_model_convert():
paddle_input_ids = paddle.to_tensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
torch_input_ids = torch.LongTensor([[0, 345, 232, 328, 740, 140, 1695, 69, 6078, 1588, 2]])
# paddle model
paddle_ckpt_path = "Qwen/Qwen2-0.5B"
config_paddle = Qwen2Config.from_pretrained(paddle_ckpt_path)
model_paddle = Qwen2ForCausalLM.from_pretrained(paddle_ckpt_path, config=config_paddle, dtype="float32")
# torch model
torch_ckpt_path = "/root/.cache/modelscope/hub/Qwen/Qwen2-0___5B"
config_torch = Qwen2Config_hf.from_pretrained(torch_ckpt_path, trust_remote_code=True)
config_torch.dtype = "float32"
model_torch = Qwen2ForCausalLM_hf.from_pretrained(torch_ckpt_path, config=config_torch, trust_remote_code=True)
model_paddle.eval()
model_torch.eval()
# Manual verification
out_paddle = model_paddle(paddle_input_ids)[0]
out_torch = model_torch(torch_input_ids, return_dict=False)[0]
assert np.allclose(out_paddle.numpy(), out_torch.detach().numpy(), rtol=1e-5, atol=1e-4)
# Use padiff for verification
inp = ({"input_ids": torch_input_ids,
"use_cache": False,
"output_attentions": False,
"output_hidden_states": False,
"return_dict": False},
{"input_ids": paddle_input_ids})
# diff_phase can be forward, backward or both
auto_diff(model_torch, model_paddle, inp, atol=1e-4, rtol=1e3, auto_init=False, diff_phase="both", compare_mode="strict")
eval_model_convert()
Precision alignment reference (verification standard):
+------------------+------+-----------------------+---------------------+-------------------------------------+
| model | size | logits diff (float32) | loss diff (float32) | each tensor in all layers (float32) |
+==================+======+=======================+=====================+=====================================+
| Qwen/Qwen2-0.5B | 0.5B | 1e-4 | 1e-5 | 1e-4 |
+------------------+------+-----------------------+---------------------+-------------------------------------+
| Qwen/Qwen2-1.5B | 1.5B | 1e-3 | 1e-5 | 1e-3 |
+------------------+------+-----------------------+---------------------+-------------------------------------+
| Qwen/Qwen2-7B | 7B | 1e-3 | 1e-5 | 1e-3 |
+------------------+------+-----------------------+---------------------+-------------------------------------+
| Qwen/Qwen1.5-14B | 14B | 1e-4 | 1e-5 | 1e-4 |
+------------------+------+-----------------------+---------------------+-------------------------------------+
3.3 Model Training Alignment
------------------------------------------
【Basic Process】
After completing previous steps, proceed to full-data training alignment:
1. Prepare train/eval data, data loaders, and model
2. Initialize model
3. Load configuration and start training to obtain final model and evaluation metrics.
【Notes】
#. 【Strongly Recommended】Complete backward alignment before training alignment. Uncertain factors include: dataset differences, framework discrepancies between PaddlePaddle and reference code in training mode, and initialization parameters.
#. During training alignment, some output differences are acceptable. For example, in SST-2 classification task, difference <0.15% is considered normal. Adjust diff_threshold in ReprodDiffHelper.report as needed.
#. Training fluctuations are normal. If final convergence differs, check:
* Verify Dropout, BatchNorm, and other modules with hyperparameters.
* Generate a pretrained model using reference code, convert to PaddlePaddle model, and compare convergence curves.
* Use reference code's DataLoader output for training to exclude data loading effects.

Contribute Pre-trained Model Weights
====================================================================================
1. Model Network Architecture Types
------------------------------------------------------------------------------------
PaddleNLP currently supports most mainstream pre-trained model architectures, including both Baidu's self-developed models (e.g., ERNIE series) and widely-used models in the industry (e.g., BERT, ALBERT, GPT, RoBERTa, XLNet, etc.).
For a comprehensive list of supported pre-trained model architectures in PaddleNLP, please refer to
`Transformer Pre-trained Models Collection <https://paddlenlp.readthedocs.io/zh/latest/model_zoo/transformers.html>`_
(continuously updated, and we warmly welcome contributions of new models: `How to Contribute New Models <https://paddlenlp.readthedocs.io/zh/latest/community/contribute_models/contribute_new_models.html>`_).
2. Model Parameter Weight Types
------------------------------------------------------------------------------------
We sincerely welcome contributions of high-quality model parameter weights.
Supported parameter weight types include but are not limited to (taking BERT model as example):
- BERT pre-trained model parameter weights not yet included in PaddleNLP
(e.g., `bert-base-japanese-char <https://huggingface.co/cl-tohoku/bert-base-japanese-char>`, `danish-bert-botxo <https://huggingface.co/Maltehb/danish-bert-botxo>`_);
- Pre-trained BERT model weights in vertical domains (e.g., mathematics, finance, legal, medical, etc.)
(e.g., `MathBERT <https://huggingface.co/tbs17/MathBERT>`, `finbert <https://huggingface.co/ProsusAI/finbert>`_);
- Fine-tuned BERT model weights on specific downstream tasks
(e.g., `bert-base-multilingual-uncased-sentiment <https://huggingface.co/nlptown/bert-base-multilingual-uncased-sentiment>`,
`bert-base-NER <https://huggingface.co/dslim/bert-base-NER>`_).

3. Parameter Weight Format Conversion
------------------------------------------------------------------------------------
When we want to contribute model weights from an open-source project on GitHub, but find the weights saved in other deep learning framework formats (PyTorch, TensorFlow, etc.),
we need to perform model format conversion between different deep learning frameworks. The following link provides a detailed tutorial on PyTorch to Paddle model format conversion:
`PyTorch to Paddle Model Format Conversion Documentation <./convert_pytorch_to_paddle.rst>`_.
4. Contribution Process
------------------------------------------------------------------------------------
4.1 Preparing Weight-related Files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Generally, we need to prepare four files for parameter weight contributions: **model_state.pdparams**, **vocab.txt**, **tokenizer_config.json**,
and **model_config.json**.
- The model_state.pdparams file can be obtained through the aforementioned parameter weight format conversion process;
- The vocab.txt file can directly use the original model's corresponding vocab file (depending on the model's tokenizer type, this filename might be spiece.model, etc.);
- The model_config.json file can refer to the model_config.json file saved via the corresponding model.save_pretrained() interface;
- The tokenizer_config.json file can refer to the tokenizer_config.json file saved via the corresponding tokenizer.save_pretrained() interface;
4.2 Creating Personal Directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If this is your first time contributing weights, you need to create a new directory under ``PaddleNLP/community/``.
The directory name should use your GitHub username, e.g., creating a directory ``PaddleNLP/community/yingyibiao/``.
If a personal directory already exists, you can skip this step.
4.3 Creating Weight Directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Create a new weight directory under your personal directory from step 4.2. The weight directory name should be the name of the model weights being contributed.
For example, to contribute a model called ``bert-base-uncased-sst-2-finetuned``,
create a weight directory ``PaddleNLP/community/yingyibiao/bert-base-uncased-sst-2-finetuned/``
4.4 Add PR-related files in the weights directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Add two files under the directory from step 4.3: ``README.md`` and ``files.json``.
- ``README.md`` contains detailed introduction, usage examples, weight sources, etc. about your contributed weights.
- ``files.json`` contains the weight-related files and corresponding addresses obtained in step 4.1. An example of files.json content is shown below. Just replace *yingyibiao* and *bert-base-uncased-sst-2-finetuned* in the URLs with your GitHub username and weight name respectively.
.. code:: python
{
"model_config_file": "https://bj.bcebos.com/paddlenlp/models/transformers/community/yingyibiao/bert-base-uncased-sst-2-finetuned/model_config.json",
"model_state": "https://bj.bcebos.com/paddlenlp/models/transformers/community/yingyibiao/bert-base-uncased-sst-2-finetuned/model_state.pdparams",
"tokenizer_config_file": "https://bj.bcebos.com/paddlenlp/models/transformers/community/yingyibiao/bert-base-uncased-sst-2-finetuned/tokenizer_config.json",
"vocab_file": "https://bj.bcebos.com/paddlenlp/models/transformers/community/yingyibiao/bert-base-uncased-sst-2-finetuned/vocab.txt"
}
4.5 Submit PR on GitHub for contribution
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- For first-time open source contributors, please refer to `first-contributions <https://github.com/firstcontributions/first-contributions>`_.
- Please refer to the `bert-base-uncased-sst-2-finetuned PR <.>`_ for an example of model weight contribution PR.

Model Format Conversion
==========================================
0. Preface
------------------------------------------
This article explains how to convert model weights between different frameworks (using PyTorch to Paddle framework conversion as an example).
The model format conversion process requires users to have a detailed understanding of the model architecture. Successfully completing the conversion will help deepen users' understanding of the model structure. Let's begin this interesting journey!
1. Overview of Model Weight Files
------------------------------------------
Regardless of the framework, when saving trained models, we need to persist the model's parameter weights. When loading a saved model, we need to load these parameter weights and reassign them to the corresponding model.
Both PyTorch and Paddle frameworks use serialization and deserialization of the model's ``state dict`` (state dictionary) for parameter storage and loading. From a data structure perspective, the ``state dict`` is a dictionary (e.g., Python dict) where keys are model parameter names (string type) and values are corresponding parameters (Tensor type). During saving, the framework first retrieves the target object's ``state dict`` and saves it to disk. During loading, the framework first loads the saved ``state dict`` from disk and applies it to the target object using the ``set_state_dict()`` method.
By convention, model files saved in Paddle framework typically use the `.pdparams` suffix, while PyTorch models commonly use `.pt`, `.pth`, or `.bin` suffixes. Although the suffix doesn't affect model saving/loading, we generally follow this naming convention.
2. Overview of Model ``state dict``
------------------------------------------
Now that we've briefly introduced model files and their stored ``state dict``, let's examine a concrete example to better understand the ``state dict``.
``LeNet``, proposed by Yann LeCun et al. in 1998, is a CNN model successfully applied to handwritten digit recognition. Paddle provides an integrated implementation of ``LeNet``. The following code demonstrates loading this model and outputting its corresponding ``state dict``:
.. code:: python
from paddle.vision.models import LeNet
# Instantiate model
model = LeNet()
# Print state dict keys
print("State dict keys:")
for key in model.state_dict().keys():
print(key)
# Print state dict contents
print("\nState dict items:")
for key, value in model.state_dict().items():
print(f"{key}: {value.shape}")
The output shows the model's parameter names and shapes:
```
State dict keys:
conv1.weight
conv1.bias
conv2.weight
conv2.bias
fc1.weight
fc1.bias
fc2.weight
fc2.bias
fc3.weight
fc3.bias
State dict items:
conv1.weight: [6, 1, 5, 5]
conv1.bias: [6]
conv2.weight: [16, 6, 5, 5]
conv2.bias: [16]
fc1.weight: [120, 400]
fc1.bias: [120]
fc2.weight: [84, 120]
fc2.bias: [84]
fc3.weight: [10, 84]
fc3.bias: [10]
```
This output reveals several key characteristics of the ``state dict``:
1. Parameter names follow strict naming conventions reflecting the model's architecture
2. Parameter shapes correspond to layer configurations
3. Contains both weight and bias parameters for each layer
4. Parameter names directly reflect their position in the network
This example demonstrates how the ``state dict`` faithfully records all model parameters and their hierarchical relationships.
python
>>> import paddle
>>> from paddle.vision.models import LeNet
>>> model = LeNet()
>>> model.state_dict().keys() # Output all keys of state_dict
odict_keys(['features.0.weight', 'features.0.bias', 'features.3.weight', 'features.3.bias',
'fc.0.weight', 'fc.0.bias', 'fc.1.weight', 'fc.1.bias', 'fc.2.weight', 'fc.2.bias'])
>>> model.state_dict()['features.0.weight'] # Output the value corresponding to 'features.0.weight'
Parameter containing:
Tensor(shape=[6, 1, 3, 3], dtype=float32, place=CPUPlace, stop_gradient=False,
[[[[-0.31584871, 0.27280194, -0.43816274],
[ 0.06681869, 0.44526964, 0.80944657],
[ 0.05796078, 0.57411081, 0.15335406]]],
...
...
[[[-0.07211500, -0.14458601, -1.11733580],
[ 0.53036308, -0.19761689, 0.56962037],
[-0.09760553, -0.02011104, -0.50577533]]]])
We can obtain all parameter names of the model through ``model.state_dict().keys()``.
The ``LeNet`` model contains 10 parameter groups: *'features.0.weight'*, *'features.0.bias'*, *'features.3.weight'*,
*'features.3.bias'*, *'fc.0.weight'*, *'fc.0.bias'*, *'fc.1.weight'*, *'fc.1.bias'*, *'fc.2.weight'*, and *'fc.2.bias'*.
By querying ``model.state_dict()['features.0.weight']``, we can examine the specific weight values of the **'features.0.weight'** parameter.
The output shows this weight is a Tensor with dtype=float32 and shape=[6, 1, 3, 3].
3. Weight Format Conversion Using ``state_dict``
------------------------------------------------
After understanding model storage/loading and related ``state_dict``, let's examine the concrete steps for model format conversion.
Generally, we can perform model format conversion through ``state_dict``.
The mutual conversion of **state dict** can assist us in model format conversion.
Taking model weight conversion from PyTorch to Paddle framework as an example, the specific conversion process is:
1. Load PyTorch model to obtain ``state dict``
2. Convert PyTorch's ``state dict`` to Paddle's ``state dict``
3. Save Paddle's ``state dict`` to obtain Paddle model.
Let's examine a concrete example: ``'bert-base-uncased'`` is a 12-layer BERT English model open-sourced by Google. This model is integrated in both PaddleNLP (Paddle framework) and HuggingFace's transformers (PyTorch framework), with completely identical parameter quantities and specific parameter values. We can compare the ``state dict`` of these two models to understand conversion details.
3.1 ``state dict`` in PyTorch Framework
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First, load the ``'bert-base-uncased'`` model from transformers:
.. code::
>>> import torch
>>> model_name = "bert-base-uncased"
>>> # Model download: https://huggingface.co/bert-base-uncased/blob/main/pytorch_model.bin
>>> model_file = "pytorch_model.bin"
>>> pytorch_state_dict = torch.load(model_file)
>>> pytorch_state_dict.keys()

'cls.seq_relationship.weight', 'cls.seq_relationship.bias'])
**odict_keys** (ordered dictionary keys) displays the ordered dictionary keys corresponding to the PyTorch model file
```state dict``` keys:
Upon closer inspection, we can categorize the parameters into several major modules: **embeddings** module, **encoder_layers** module, **pooler** module, and **cls** module.
Let's interpret each module in conjunction with BERT's actual structure:
- **embeddings** module
Parameters starting with *'bert.embeddings'* belong to the embeddings module, including the word_embeddings matrix, position_embeddings matrix, token_type_embeddings matrix, and LayerNorm layer parameters in the embeddings module.
- **encoder_layers** module
Parameters starting with *'bert.encoder.layer'* correspond to each encoder layer. We observe that the ```'bert-base-uncased'``` model contains 12 encoder layers (numbered 0-11), all sharing identical architecture. Each encoder layer mainly consists of a *self-attention* module and a *feed-forward* module. Let's examine the parameters of the first encoder layer (numbered 0, parameters starting with 'bert.encoder.layer.0'):
First, the *self-attention* module:
* *'attention.self.query'*, *'attention.self.key'*, and *'attention.self.value'* represent the query matrix, key matrix, and value matrix in the self-attention structure.
* *'attention.output.dense'* is the linear layer in the self-attention structure.
* *'attention.output.LayerNorm'* denotes the LayerNorm layer following the self-attention structure.
Next, the *feed-forward* module corresponds to parameters starting with 'intermediate.dense' and 'output.dense'. After the feed-forward layer, there's another *LayerNorm* layer, corresponding to parameters starting with 'output.LayerNorm'.
- **pooler** module
The pooler module follows the last encoder layer, performing pooling operations on the output of the final encoder layer.
- **cls** module
The cls module calculates parameters for MLM (masked language model) and NSP (next sentence prediction) tasks. Parameters starting with 'cls.predictions' are for MLM tasks, while 'cls.seq_relationship' parameters are for NSP prediction tasks.
3.2 ```state dict``` in Paddle Framework
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We should now have a deeper understanding of BERT's architecture and corresponding parameters. Next, let's load the model from PaddleNLP:
.. code::
>>> import paddle
>>> model_name = "bert-base-uncased"
>>> # Model download URL: https://bj.bcebos.com/paddlenlp/models/transformers/bert-base-uncased.pdparams
>>> model_file = "bert-base-uncased.pdparams"
>>> paddle_state_dict = paddle.load(model_file)
>>> paddle_state_dict.keys()
dict_keys(['bert.embeddings.word_embeddings.weight', 'bert.embeddings.position_embeddings.weight', 'bert.embeddings.token_type_embeddings.weight',
'bert.embeddings.layer_norm.weight', 'bert.embeddings.layer_norm.bias',
'bert.encoder.layers.0.self_attn.q_proj.weight', 'bert.encoder.layers.0.self_attn.q_proj.bias',
'bert.encoder.layers.0.self_attn.k_proj.weight', 'bert.encoder.layers.0.self_attn.k_proj.bias',
'bert.encoder.layers.0.self_attn.v_proj.weight', 'bert.encoder.layers.0.self_attn.v_proj.bias',
'bert.encoder.layers.0.self_attn.out_proj.weight', 'bert.encoder.layers.0.self_attn.out_proj.bias',
'bert.encoder.layers.0.linear1.weight', 'bert.encoder.layers.0.linear1.bias',
'bert.encoder.layers.0.linear2.weight', 'bert.encoder.layers.0.linear2.bias',
'bert.encoder.layers.0.norm1.weight', 'bert.encoder.layers.0.norm1.bias',
'bert.encoder.layers.0.norm2.weight', 'bert.encoder.layers.0.norm2.bias',
'bert.encoder.layers.1'...
...
...
'bert.encoder.layers.10'...
'bert.encoder.layers.11.self_attn.q_proj.weight', 'bert.encoder.layers.11.self_attn.q_proj.bias',
'bert.encoder.layers.11.self_attn.k_proj.weight', 'bert.encoder.layers.11.self_attn.k_proj.bias',
'bert.encoder.layers.11.self_attn.v_proj.weight', 'bert.encoder.layers.11.self_attn.v_proj.bias',
'bert.encoder.layers.11.self_attn.out_proj.weight', 'bert.encoder.layers.11.self_attn.out_proj.bias',
'bert.encoder.layers.11.linear1.weight', 'bert.encoder.layers.11.linear1.bias',
'bert.encoder.layers.11.linear2.weight', 'bert.encoder.layers.11.linear2.bias',
'bert.encoder.layers.11.norm1.weight', 'bert.encoder.layers.11.norm1.bias',
'bert.encoder.layers.11.norm2.weight', 'bert.encoder.layers.11.norm2.bias',
'bert.pooler.dense.weight', 'bert.pooler.dense.bias',
'cls.predictions.decoder_weight', 'cls.predictions.decoder_bias',
'cls.predictions.transform.weight', 'cls.predictions.transform.bias',
'cls.predictions.layer_norm.weight', 'cls.predictions.layer_norm.bias',
'cls.seq_relationship.weight', 'cls.seq_relationship.bias'])
```
The `state dict` is stored using a dict. We can see that the `state dict` of both frameworks are highly similar. Let's compare them:
- The storage mechanisms are similar: PyTorch uses an ordered_dict from Python to store model parameter states, while Paddle uses a standard Python dict.
- The structures are also similar: both can be divided into embeddings, encoder_layer, pooler, cls, etc. (This is intuitive since the model architectures and parameters are identical).
- However, there are some differences: there are subtle variations in the keys of the `state dict` between the two, which result from differences in parameter naming conventions in their respective implementations.
3.3 Comparison of PyTorch and Paddle `state dict`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Next, we will perform a detailed parameter name and weight mapping between the two `state dict`s. The following table presents the organized `state_dict` comparison:

The parameters and weights of the ``state dict`` help us correctly perform the conversion of the ``state dict``.
From the parameter names, we can observe a basic correspondence, for example:
* `bert.embeddings.LayerNorm.gamma` corresponds to `bert.embeddings.layer_norm.weight`;
* `bert.embeddings.LayerNorm.beta` corresponds to `bert.embeddings.layer_norm.bias`;
* `bert.encoder.layer.0.attention.self.query.weight` corresponds to `bert.encoder.layers.0.self_attn.q_proj.weight`;
* `bert.encoder.layer.0.attention.self.query.bias` corresponds to `bert.encoder.layers.0.self_attn.q_proj.bias`.
The order of parameters is generally consistent, but there are exceptions, such as:
* `bert.encoder.layers.0.norm1.weight` corresponds to `bert.encoder.layer.0.attention.output.LayerNorm.gamma`;
* `bert.encoder.layers.0.norm1.bias` corresponds to `bert.encoder.layer.0.attention.output.LayerNorm.beta`;
* `bert.encoder.layer.0.intermediate.dense.weight` corresponds to `bert.encoder.layers.0.linear1.weight`;
* `bert.encoder.layer.0.output.dense.weight` corresponds to `bert.encoder.layers.0.linear2.weight`;
* `bert.encoder.layer.0.output.LayerNorm.gamma` corresponds to `bert.encoder.layers.0.norm2.weight`.
The correct parameter correspondence may require us to examine the specific code for determination. We have already established accurate one-to-one mapping of the keys in the table above. After establishing the key correspondences, we can proceed with value mapping.
If you observe carefully, you'll notice that some parameter values have different shapes. For example, the corresponding parameters `bert.encoder.layer.0.intermediate.dense.weight` and `bert.encoder.layers.0.linear1.weight` have value shapes of `[3072, 768]` and `[768, 3072]` respectively, which are transposes of each other. This is because PyTorch saves the weights of `nn.Linear` modules in transposed form. Therefore, when processing the `state dict`, we need to perform corresponding transpose operations on these linear layer parameters.
When converting, it is necessary to properly handle the shape conversion (for example, transposing the parameter weights of the nn.Linear layer in a PyTorch model and then generating the corresponding parameter weights for Paddle).
Additional details to note include several potential scenarios:
- Some model structures may have parameter processing differences leading to parameter splitting/merging operations. In such cases, we need to perform many-to-one or one-to-many parameter mappings while splitting/merging corresponding values.
- When batch norm layers are present, we need to pay attention to the todo.
3.4 bert model conversion code
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The next step is the most critical model conversion phase. This step is crucial as only correct conversion of the ``state dict`` can ensure successful accuracy validation.
Below is the model conversion code (PyTorch to Paddle):
.. code:: python
# Model conversion core code
def convert_bert_model(pretrained_torch_model, paddle_model):
torch_state_dict = pretrained_torch_model.state_dict()
paddle_state_dict = {}
# Embedding layer conversion
paddle_state_dict["embeddings.word_embeddings.weight"] = torch_state_dict["bert.embeddings.word_embeddings.weight"].detach().numpy()
# Add other embedding parameters...
# Encoder layers conversion
for i in range(config.num_hidden_layers):
# Attention weights
paddle_state_dict[f"encoder.layers.{i}.self_attn.q_proj.weight"] = torch_state_dict[f"bert.encoder.layer.{i}.attention.self.query.weight"].T.numpy()
# Add bias and other linear transformations...
# LayerNorm parameters
paddle_state_dict[f"encoder.layers.{i}.norm1.weight"] = torch_state_dict[f"bert.encoder.layer.{i}.attention.output.LayerNorm.weight"].numpy()
# Continue processing all parameters...
# Load converted parameters into Paddle model
paddle_model.set_dict(paddle_state_dict)
return paddle_model
```python
import paddle
import torch
import numpy as np
torch_model_path = "pytorch_model.bin"
torch_state_dict = torch.load(torch_model_path)
paddle_model_path = "bert_base_uncased.pdparams"
paddle_state_dict = {}
# State_dict's keys mapping: from torch to paddle
keys_dict = {
# about embeddings
"embeddings.LayerNorm.gamma": "embeddings.layer_norm.weight",
"embeddings.LayerNorm.beta": "embeddings.layer_norm.bias",
# about encoder layer
'encoder.layer': 'encoder.layers',
'attention.self.query': 'self_attn.q_proj',
'attention.self.key': 'self_attn.k_proj',
'attention.self.value': 'self_attn.v_proj',
'attention.output.dense': 'self_attn.out_proj',
'attention.output.LayerNorm.gamma': 'norm1.weight',
'attention.output.LayerNorm.beta': 'norm1.bias',
'intermediate.dense': 'linear1',
'output.dense': 'linear2',
'output.LayerNorm.gamma': 'norm2.weight',
'output.LayerNorm.beta': 'norm2.bias',
# about cls predictions
'cls.predictions.transform.dense': 'cls.predictions.transform',
'cls.predictions.decoder.weight': 'cls.predictions.decoder_weight',
'cls.predictions.transform.LayerNorm.gamma': 'cls.predictions.layer_norm.weight',
'cls.predictions.transform.LayerNorm.beta': 'cls.predictions.layer_norm.bias',
'cls.predictions.bias': 'cls.predictions.decoder_bias'
}
for torch_key in torch_state_dict:
paddle_key = torch_key
for k in keys_dict:
if k in paddle_key:
paddle_key = paddle_key.replace(k, keys_dict[k])
if ('linear' in paddle_key) or ('proj' in paddle_key) or ('vocab' in paddle_key and 'weight' in paddle_key) or ("dense.weight" in paddle_key) or ('transform.weight' in paddle_key) or ('seq_relationship.weight' in paddle_key):
paddle_state_dict[paddle_key] = paddle.to_tensor(torch_state_dict[torch_key].cpu().numpy().transpose())
else:
paddle_state_dict[paddle_key] = paddle.to_tensor(torch_state_dict[torch_key].cpu().numpy())
print("torch: ", torch_key,"\t", torch_state_dict[torch_key].shape)
print("paddle: ", paddle_key, "\t", paddle_state_dict[paddle_key].shape, "\n")
paddle.save(paddle_state_dict, paddle_model_path)
Let's take a look at this conversion code:
We need to download the PyTorch model to be converted, load the model to obtain **torch_state_dict**; **paddle_state_dict** and **paddle_model_path** define the converted
``state dict`` and model file paths;
The **keys_dict** in the code defines the key mappings between them (can be verified by comparing with the table above).
The next step is the most crucial *paddle_state_dict* construction. We map each key in the *torch_state_dict*,
to obtain the corresponding key in the *paddle_state_dict*. After obtaining the *paddle_state_dict* key, we need
to convert the value from *torch_state_dict*. If the corresponding structure is an ``nn.Linear`` module,
we also need to perform transpose operation on the value.
Finally, by saving the obtained *paddle_state_dict*, we get the corresponding Paddle model.
Thus, we have completed the model conversion and obtained the Paddle framework model ``"model_state.pdparams"``.
4. Model Weight Validation
------------------------------------------
After obtaining the model weights, we need to verify the conversion correctness through precision alignment.
We can validate through forward inference and downstream task fine-tuning.
4.1 Forward Precision Alignment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Forward precision alignment is straightforward. We only need to ensure consistent input for both frameworks,
and verify whether the outputs match. Some important notes: we need to run inference in eval mode,
set dropout to 0, and other operations to eliminate randomness effects.
In addition to the model weight file, we need to prepare the model configuration file. By placing both the model weights (model_state.pdparams)
and the model configuration file (model_config.json) in the same directory, we can perform forward precision validation.
The following provides a code example for BERT model forward alignment:
.. code::
```python
text = "Welcome to use paddle paddle and paddlenlp!"
torch_model_name = "bert-base-uncased"
paddle_model_name = "bert-base-uncased"
# torch output
import torch
import transformers
from transformers.models.bert import *
# torch_model = BertForPreTraining.from_pretrained(torch_model_name)
torch_model = BertModel.from_pretrained(torch_model_name)
torch_tokenizer = BertTokenizer.from_pretrained(torch_model_name)
torch_model.eval()
torch_inputs = torch_tokenizer(text, return_tensors="pt")
torch_outputs = torch_model(**torch_inputs)
torch_logits = torch_outputs[0]
torch_array = torch_logits.cpu().detach().numpy()
print("torch_prediction_logits shape:{}".format(torch_array.shape))
print("torch_prediction_logits:{}".format(torch_array))
# paddle output
import paddle
import paddlenlp
from paddlenlp.transformers.bert.modeling import *
import numpy as np
# paddle_model = BertForPretraining.from_pretrained(paddle_model_name)
paddle_model = BertModel.from_pretrained(paddle_model_name)
paddle_tokenizer = BertTokenizer.from_pretrained(paddle_model_name)
paddle_model.eval()
paddle_inputs = paddle_tokenizer(text)
paddle_inputs = {k:paddle.to_tensor([v]) for (k, v) in paddle_inputs.items()}
paddle_outputs = paddle_model(**paddle_inputs)
paddle_logits = paddle_outputs[0]
paddle_array = paddle_logits.numpy()
print("paddle_prediction_logits shape:{}".format(paddle_array.shape))
print("paddle_prediction_logits:{}".format(paddle_array))
# the output logits should have the same shape
assert torch_array.shape == paddle_array.shape, "the output logits should have the same shape, but got : {} and {} instead".format(torch_array.shape, paddle_array.shape)
diff = torch_array - paddle_array
print(np.amax(abs(diff)))
The code will finally print the maximum difference between corresponding elements in the output matrices, which can be used to verify if we have aligned the forward accuracy.
4.2 Downstream Task Fine-tuning Verification (Optional)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When the forward accuracy is aligned, it generally indicates successful model conversion. We can also run downstream task fine-tuning for double-checking.
Similarly, we need to use identical training data, same training parameters, and same training environment to compare the convergence behavior and metrics.
5. Final Remarks

# 1. Overview
## 1.1 Background
Corresponding to task No.103: Add tie_weights capability
Weight tying (tie_weights) typically refers to sharing weights between input embeddings and output embeddings, thereby reducing network parameters and allowing more sufficient training of embedding layer parameters.
This technique is mentioned in "Attention Is All You Need" (Transformer paper), specifically in section 3.4, which describes sharing weights between encoder input embeddings, decoder input embeddings, and output linear layers. The effectiveness of this technique is validated in the paper "Using the Output Embedding to Improve Language Models".
Therefore, pre-trained language models need to implement a weight sharing function between input embeddings and output embeddings for user convenience.
Related issues:
* [https://github.com/PaddlePaddle/PaddleNLP/issues/4740](https://github.com/PaddlePaddle/PaddleNLP/issues/4740)
## 1.2 Objectives
Add a fundamental function to pre-trained language models to implement weight sharing between input embeddings and output embeddings:
- Add tie_weights functionality to PaddleNLP, aligning with HuggingFace Transformers' [tie_weights](https://huggingface.co/docs/transformers/main_classes/model#transformers.PreTrainedModel.tie_weights) implementation
- Reference: [https://github.com/huggingface/transformers/blob/v4.26.1/src/transformers/modeling_utils.py#L1172](https://github.com/huggingface/transformers/blob/v4.26.1/src/transformers/modeling_utils.py#L1172)
## 1.3 Significance
Implementing the weight tying function as a model technique to improve training efficiency and reduce model parameters.
As a fundamental model function, it facilitates experimental setup during pre-trained model architecture design, reducing model parameters and enhancing model performance.
# 2. Current Status of PaddlePaddle
Research on current framework support for this functionality. If not supported, investigate possible alternatives:
PaddlePaddle currently lacks a unified implementation for weight tying. Users need to implement this manually.
Some example code in PaddleNLP shows implementations:
(1) [Code Link 1](https://github.com/qiuwenbogdut/PaddleNLP/blob/develop/examples/language_model/transformer-xl/mem_transformer.py#L811)
```python
if tie_weight:
for i in range(len(self.crit.out_layers_weight)):
self.crit.out_layers_weight[i] = self.word_emb.emb_layers[i].weight
if tie_projs:
for i, tie_proj in enumerate(tie_projs):
if tie_proj and div_val == 1 and d_model != d_embed:
self.crit.out_projs[i] = self.word_emb.emb_projs[0]
elif tie_proj and div_val != 1:
self.crit.out_projs[i] = self.word_emb.emb_projs[i]
```
(2) [Code Link 2](https://github.com/PaddlePaddle/PaddleNLP/blob/4e5df921ff61ddae1d869c37aea621b9cac6bcd4/paddlenlp/transformers/reformer/modeling.py#L1977)
```python
def tie_weights(self):
"""
Tie the weights between the input embeddings and the output embeddings.
"""
tie_word_embeddings = (
self.tie_word_embeddings
if hasattr(self, "tie_word_embeddings")
else self.config.get("tie_word_embeddings", False)
)
if hasattr(self, "get_output_embeddings") and hasattr(self, "get_input_embeddings") and tie_word_embeddings:
output_embeddings = self.get_output_embeddings()
if output_embeddings is not None:
self._tie_or_clone_weights(output_embeddings, self.get_input_embeddings())
```
(3) [Code Link 3](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/transformers/ernie/modeling.py#L748)
```python
class ErnieLMPredictionHead(nn.Layer):
r"""
Ernie Model with a `language modeling` head on top.
"""
def __init__(
self,
config: ErnieConfig,
embedding_weights=None,
weight_attr=None,
):
super(ErnieLMPredictionHead, self).__init__()
self.transform = nn.Linear(config.hidden_size, config.hidden_size, weight_attr=weight_attr)
self.activation = getattr(nn.functional, config.hidden_act)
self.layer_norm = nn.LayerNorm(config.hidden_size)
self.decoder_weight = (
self.create_parameter(
shape=[config.vocab_size, config.hidden_size],
dtype=self.transform.weight.dtype,
attr=weight_attr,
is_bias=False,
)
if embedding_weights is None
else embedding_weights
)
self.decoder_bias = self.create_parameter(
shape=[config.vocab_size], dtype=self.decoder_weight.dtype, is_bias=True
)
```
In fact, most `tie_weights` implementations in PaddleNLP are directly handled at the model layer definition level, as seen in this [code](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/transformers/ernie/modeling.py#L748), rather than being uniformly implemented outside the model like in Transformers. The goal of this project is to explore whether we can achieve this binding externally without requiring per-model implementations.
There are two main approaches to `tie_weights` implementation in Paddle:
* One defines the `tie_weights` function in modeling.py, where the model implements `get_input_embeding()` and `get_output_embeding()` to retrieve input and output embedding layer weights, then binds them via assignment. As shown in code links (1)(2) above.
* The other directly assigns the input embedding's weight to the output layer's weight during model layer definition. The embedding's weight is directly passed to the head to construct the linear output layer, expecting to obtain weights through `get_input_embeding()` and pass them to the head layer, as shown in code link (3) above.
The ideal implementation would be to uniformly handle `tie_weights` in the [base class model_utils.py#L897](https://github.com/PaddlePaddle/PaddleNLP/blob/be80a3e30fb681e53773c265babe611d4df62ead/paddlenlp/transformers/model_utils.py#L897) to reduce developer overhead.
# III. Industry Solution Research
Describe how industry deep learning frameworks implement this feature, including current status and future trends. Research scope includes but not limited to TensorFlow, PyTorch, NumPy, etc.
(1) Currently, the `tie_weights` function is implemented in Hugging Face's Transformers library. [Code link](https://github.com/huggingface/transformers/blob/v4.26.1/src/transformers/modeling_utils.py#L1172)
```python
def tie_weights(self):
"""
Tie the weights between the input embeddings and the output embeddings.
If the `torchscript` flag is set in the configuration, can't handle parameter sharing so we are cloning the
weights instead.
"""
if getattr(self.config, "tie_word_embeddings", True):
output_embeddings = self.get_output_embeddings()
if output_embeddings is not None:
self._tie_or_clone_weights(output_embeddings, self.get_input_embeddings())
if getattr(self.config, "is_encoder_decoder", False) and getattr(self.config, "tie_encoder_decoder", False):
if hasattr(self, self.base_model_prefix):
self = getattr(self, self.base_model_prefix)
self._tie_encoder_decoder_weights(self.encoder, self.decoder, self.base_model_prefix)
for module in self.modules():
if hasattr(module, "_tie_weights"):
module._tie_weights()
```
(2) Tensor2Tensor library's tie_weights implementation code [code link](https://github.com/tensorflow/tensor2tensor/blob/316c9ce2f2b2373f44f5be0da712dda3e5861a75/tensor2tensor/layers/modalities.py#L1106)
```python
def symbol_top(body_output, targets, model_hparams, vocab_size):
del targets # unused arg
if model_hparams.shared_embedding_and_softmax_weights:
scope_name = "shared"
reuse = tf.AUTO_REUSE
else:
scope_name = "softmax"
reuse = False
with tf.variable_scope(scope_name, reuse=reuse):
body_output_shape = common_layers.shape_list(body_output)
var = get_weights(model_hparams, vocab_size, body_output_shape[-1])
if (model_hparams.factored_logits and
model_hparams.mode == tf_estimator.ModeKeys.TRAIN):
# insert channels dimension
body_output = tf.expand_dims(body_output, 3)
return common_layers.FactoredTensor(body_output, var)
else:
body_output = tf.reshape(body_output, [-1, body_output_shape[-1]])
logits = tf.matmul(body_output, var, transpose_b=True)
return tf.reshape(logits,
body_output_shape[:-1] + [1, vocab_size])
```
(3) Implementation of weight tying in fairseq library [code link](https://github.com/facebookresearch/fairseq/blob/main/fairseq/models/fconv.py#L480)
```python
self.fc2 = Linear(in_channels, out_embed_dim)
if share_embed:
assert out_embed_dim == embed_dim, (
"Shared embedding weights require matching dimensions "
"out_embed_dim={} vs embed_dim={}".format(out_embed_dim, embed_dim)
)
self.fc3 = nn.Linear(out_embed_dim, num_embeddings)
self.fc3.weight = self.embed_tokens.weight
else:
self.fc3 = Linear(out_embed_dim, num_embeddings, dropout=dropout)
```
# 4. Comparative Analysis
Both Paddle and HuggingFace's Transformers are developed based on dynamic graphs. Therefore, we plan to implement the functionality by referencing the implementation approach of the tie_weight function from HuggingFace's Transformers.
# 5. Design Approach and Implementation Plan
We will implement the solution based on Paddle by referencing the implementation approach from HuggingFace's Transformers.
Implementation steps for the tie_weight function:
1. Obtain the weight object A of the model's input embedding
2. Obtain the weight object B of the model's output embedding
3. Make both A and B point to the same weight value
## Naming and Parameter Design
Reference: [PaddlePaddle API Design and Naming Conventions](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/dev_guides/api_contributing_guides/api_design_guidelines_standard_cn.html)
## Underlying OP Design
## API Implementation Plan
# 6. Testing and Validation Considerations
Reference: [New API Testing and Validation Standards](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/dev_guides/api_contributing_guides/api_accpetance_criteria_cn.html)
Two methods to test tie_weight:
* Directly check the id consistency between the output layer weight and input layer weight. If consistent, pass; otherwise fail.
* Train for several steps, after several backward passes, check if the output layer weight and input layer weight remain consistent. If consistent, pass; otherwise fail.
We will use id consistency check for unit testing: build unit tests to verify whether the id of the weight obtained from get_input_embedding is consistent with the id from get_output_embedding. If consistent, pass; otherwise fail.
# 7. Feasibility Analysis and Timeline Planning
Design a small script to validate this approach:
```python
# Here is a simple validation script example
import paddle
class TestModel(paddle.nn.Layer):
def __init__(self):
super().__init__()
self.embedding = paddle.nn.Embedding(1000, 256)
self.dense = paddle.nn.Linear(256, 1000)
def tie_weights(self):
self.dense.weight = self.embedding.weight
model = TestModel()
model.tie_weights()
print(id(model.embedding.weight) == id(model.dense.weight)) # Should output True
```
```python
import numpy as np
from paddle.nn import Embedding
"""step1 Define two distinct embedding objects AA and BB"""
print('------------step1')
AA = Embedding(1,2)
BB = Embedding(1,2)
AA.weight = BB.weight # Bind the weights
""" step2 Test the binding result"""
print('------------step2')
print('Check if AA and BB have same id:', AA is BB,id(AA), id(BB))
print('Check if AA.weight and BB.weight have same id:',AA.weight is BB.weight,id(AA.weight), id(BB.weight))
print("AA.weight: ",AA.weight)
print("BB.weight: ",BB.weight)
""" step3 Attempt to modify AA's weight value and verify if BB's weight changes accordingly"""
print('------------step3')
AA.weight.set_value(np.array([[4.0,6.0]],dtype=np.float32))
print('Check if modified AA.weight and BB.weight have same id:',AA.weight is BB.weight,id(AA.weight), id(BB.weight))
print("AA.weight after modification: ",AA.weight)
print("BB.weight:",BB.weight)
```

## Introduction to Model Compression API Features
The PaddleNLP Model Compression API supports pruning and quantization of fine-tuned models on downstream ERNIE tasks to reduce model size, memory usage, computation, and enhance inference speed, thereby reducing deployment difficulty. The Model Compression API is effective and easy to use. Currently, the pruning feature supports the width-adaptive pruning strategy in DynaBERT; quantization supports static offline quantization methods (PTQ), quantization-aware training (QAT), and Embedding quantization. PTQ requires no training and only a small amount of calibration data to export a quantized model. QAT is similar to the training process of FP32 models and can generally achieve lossless precision. The Embedding quantization process is relatively simple, requiring neither training nor calibration data.
- **Effective**: It has been validated on tasks such as classification (including text classification, text matching, natural language inference, pronoun disambiguation, reading comprehension), sequence labeling, and extractive reading comprehension, achieving nearly lossless precision. For example, for models with 12L768H and 6L768H structures, pruning with a width retention ratio of 2/3 can achieve nearly lossless precision, and the inference speed of the pruned model can reach 1-2 times the original. The inference speed of a quantized 6L768H model can reach 2-3 times that before quantization.
- **Simple and Easy to Use**: Model compression tasks can be initiated in just a few simple steps.
##### ERNIE 3.0 Compression Results
As shown in the table below, the ERNIE 3.0-Medium (6-layer, 384-hidden, 12-heads) model achieves approximately 3x acceleration across three types of tasks (text classification, sequence labeling, extractive reading comprehension) after pruning + quantization, with an average precision loss across all tasks controlled within 0.5 (0.46).

### Quick Start Examples for Model Compression in Three Major Scenarios
This project provides examples of using the compression API in three major scenarios: classification (including tasks such as text classification, text matching, natural language inference, and pronoun disambiguation), sequence labeling, and extractive reading comprehension. You can refer to the scripts [compress_seq_cls.py](../../slm/model_zoo/ernie-3.0/compress_seq_cls.py), [compress_token_cls.py](../../slm/model_zoo/ernie-3.0/compress_token_cls.py), and [compress_qa.py](../../slm/model_zoo/ernie-3.0/compress_qa.py) under the [ERNIE 3.0](../../slm/model_zoo/ernie-3.0) directory for each scenario. The startup methods are as follows:
```shell
# Classification task
# This script supports 7 classification tasks in CLUE, with different hyperparameters. Therefore, hyperparameter configurations for classification tasks are set using config.yml
python compress_seq_cls.py \
--dataset "clue tnews" \
--model_name_or_path best_models/TNEWS \
--output_dir ./
# Sequence labeling task
python compress_token_cls.py \
--dataset "msra_ner" \
--model_name_or_path best_models/MSRA_NER \
--output_dir ./ \
--max_seq_length 128 \
--per_device_train_batch_size 32 \
--per_device_eval_batch_size 32 \
--learning_rate 0.00005 \
--remove_unused_columns False \
--num_train_epochs 3
# Reading comprehension task
python compress_qa.py \
--dataset "clue cmrc2018" \
--model_name_or_path best_models/CMRC2018 \
--output_dir ./ \
--max_seq_length 512 \
--learning_rate 0.00003 \
--num_train_epochs 8 \
--per_device_train_batch_size 24 \
--per_device_eval_batch_size 24 \
--max_answer_length 50 \
```
The example code uses a built-in dataset from `datasets` for compression. If you wish to use a custom dataset for compression, please refer to the [datasets custom dataset loading documentation](https://huggingface.co/docs/datasets/loading).
<a name="four-step-model-compression"></a>
## Four-Step Model Compression
### Environment Dependencies
- paddlepaddle-gpu >=2.4.1
- paddlenlp >= 2.5
- paddleslim >= 2.4.0
The compression functionality in the model compression API relies on the latest `paddleslim` package. You can install it by running the following command:
```shell
pip install paddleslim -i https://pypi.tuna.tsinghua.edu.cn/simple
```
The usage of the model compression API is generally divided into four steps:
- Step 1: Use `PdArgumentParser` to parse hyperparameters passed from the command line to obtain the compression parameters `compression_args`;
- Step 2: Instantiate a Trainer and call the `compress()` compression API;
- Step 3: Implement custom evaluation functions and loss calculation functions (optional as needed) to adapt to custom compression tasks;
- Step 4: Pass parameters and run the compression script.
**Example Code**
```python
from paddlenlp.trainer import PdArgumentParser, CompressionArguments
# Step1: Use `PdArgumentParser` to parse hyperparameters passed from the command line to obtain the compression parameters `compression_args`;
parser = PdArgumentParser(CompressionArguments)
compression_args = parser.parse_args_into_dataclasses()
# Step2: Instantiate a Trainer and call compress()
trainer = Trainer(
model=model,
args=compression_args,
data_collator=data_collator,
train_dataset=train_dataset,
eval_dataset=eval_dataset,
criterion=criterion)
# Step 3: If using built-in models and evaluation methods, there is no need to implement custom evaluation functions and loss calculation functions
trainer.compress()
```
```shell
# Step 4: Pass parameters and run the compression script
python compress.py \
--output_dir ./compress_models \
--per_device_train_batch_size 32 \
--per_device_eval_batch_size 32 \
--num_train_epochs 4 \
--width_mult_list 0.75 \
--batch_size_list 4 8 16 \
--batch_num_list 1 \
```
<a name="obtain-compression-parameters-compression_args"></a>
### Step 1: Obtain Compression Parameters `compression_args`
Use
The `PdArgumentParser` object parses hyperparameters obtained from the command line to generate `compression_args`, which are then passed to the `Trainer` object. The method to obtain `compression_args` is typically as follows:
```python
from paddlenlp.trainer import PdArgumentParser, CompressionArguments
# Step 1: Use `PdArgumentParser` to parse hyperparameters passed from the command line to obtain compression parameters `compression_args`;
parser = PdArgumentParser(CompressionArguments)
compression_args = parser.parse_args_into_dataclasses()
```
<a name="instantiate-trainer-and-call-compress"></a>
### Step 2: Instantiate Trainer and Call Compress
<a name="trainer-instantiation-parameters-introduction"></a>
#### Trainer Instantiation Parameters Introduction
- **--model**: The model to be compressed. Currently supports models with similar structures such as ERNIE, BERT, RoBERTa, ERNIE-M, ELECTRA, ERNIE-Gram, PP-MiniLM, TinyBERT, which are fine-tuned on downstream tasks. When the pre-trained model is ERNIE, it needs to inherit from `ErniePretrainedModel`. For classification tasks, it can be obtained via `AutoModelForSequenceClassification.from_pretrained(model_name_or_path)`, where the `model_name_or_path` directory should contain the files model_config.json and model_state.pdparams;
- **--data_collator**: For all three types of tasks, PaddleNLP's predefined [DataCollator class](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/data/data_collator.py) can be used. The `data_collator` can perform operations such as `Pad` on the data. Refer to the [example code](../../slm/model_zoo/ernie-3.0/compress_seq_cls.py) for usage;
- **--train_dataset**: The training set used for pruning, which is task-specific data. For loading custom datasets, refer to the [documentation](https://huggingface.co/docs/datasets/loading). It can be None if pruning is not initiated;
- **--eval_dataset**: The evaluation set used for pruning training, also the calibration data for quantization, which is task-specific data. For loading custom datasets, refer to the [documentation](https://huggingface.co/docs/datasets/loading). It is a required parameter for the Trainer;
- **--tokenizer**: The `tokenizer` corresponding to the model `model`, which can be obtained using `AutoTokenizer.from_pretrained(model_name_or_path)`.
To obtain.
- **--criterion** The method for calculating the model's loss, which can be an `nn.Layer` object or a function, is used in `ofa_utils.py` to compute the model's loss for calculating gradients to determine the importance of neurons.
Example definition of the `criterion` function:
```python
# Supported form one:
def criterion(logits, labels):
loss_fct = paddle.nn.BCELoss()
start_ids, end_ids = labels
start_prob, end_prob = outputs
start_ids = paddle.cast(start_ids, 'float32')
end_ids = paddle.cast(end_ids, 'float32')
loss_start = loss_fct(start_prob, start_ids)
loss_end = loss_fct(end_prob, end_ids)
loss = (loss_start + loss_end) / 2.0
return loss
# Supported form two:
class CrossEntropyLossForSQuAD(paddle.nn.Layer):
def __init__(self):
super(CrossEntropyLossForSQuAD, self).__init__()
def forward(self, y, label):
start_logits, end_logits = y
start_position, end_position = label
start_position = paddle.unsqueeze(start_position, axis=-1)
end_position = paddle.unsqueeze(end_position, axis=-1)
start_loss = paddle.nn.functional.cross_entropy(input=start_logits,
label=start_position)
end_loss = paddle.nn.functional.cross_entropy(input=end_logits,
label=end_position)
loss = (start_loss + end_loss) / 2
return loss
```
Instantiate a `Trainer` object with the above parameters, and then directly call `compress()`. `compress()` will enter different branches based on the selected strategy to perform pruning or quantization.
**Example Code**
```python
def custom_evaluate(model, dataloader):
# Initialize evaluation metrics
metric = Accuracy() # or any other metric you need
model.eval()
for batch in dataloader:
# Forward pass
inputs, labels = batch
logits = model(inputs)
# Update metric
metric.update(logits, labels)
# Return the computed metric
return metric.compute()
```
### Step 3: Implement a Custom Evaluation Function to Adapt to Custom Compression Tasks
When using the DynaBERT pruning feature, if the model and metrics do not conform to the conditions in the table below, a custom evaluation function in the model compression API needs to be implemented.
Currently, the DynaBERT pruning feature only supports three types of built-in PaddleNLP classes such as SequenceClassification, and the corresponding built-in evaluators are Accuracy, F1, and Squad.
| Model class name | SequenceClassification | TokenClassification | QuestionAnswering |
|------------------|------------------------|---------------------|-------------------|
| Metrics | Accuracy | F1 | Squad |
Please note the following three conditions:
- If the model is a custom model, it needs to inherit from `XXXPretrainedModel`. For example, when the pre-trained model is ERNIE, it should inherit from `ErniePretrainedModel`. The model must support importing via `from_pretrained()` with only `pretrained_model_name_or_path` as a required parameter, and the `forward` function should return `logits` or a `tuple of logits`.
- If the model is custom or the dataset is particularly unique, and the loss calculation in the compression API does not meet the requirements, a custom `custom_evaluate` evaluation function needs to be implemented. This function must support both `paddleslim.nas.ofa.OFA` models and `paddle.nn.layer` models. Refer to the example code below.
- The function should take `model` and `dataloader` as inputs and return the model's evaluation metric (a single float value).
- Pass this function to the `custom_evaluate` parameter in the `compress()` method.
Example definition of the `custom_evaluate()` function:
```python
import paddle
from paddle.metric import Accuracy
@paddle.no_grad()
def evaluate_seq_cls(self, model, data_loader):
metric = Accuracy()
model.eval()
metric.reset()
for batch in data_loader:
logits = model(input_ids=batch['input_ids'],
token_type_ids=batch['token_type_ids'])
# Supports paddleslim.nas.ofa.OFA model and nn.layer model.
if isinstance(model, paddleslim.nas.ofa.OFA):
logits = logits[0]
correct = metric.compute(logits, batch['labels'])
metric.update(correct)
res = metric.accumulate()
logger.info("acc: %s, " % res)
model.train()
return res
```
When calling `compress()`, pass in this custom function:
```python
trainer.compress(custom_evaluate=evaluate_seq_cls)
```
<a name="Pass-parameters-and-run-compression-script"></a>
### Step 4: Pass parameters and run the compression script
This step primarily involves passing the parameters required for compression via the command line and initiating the compression script.
Compression initiation command:
**Example Code**
```shell
# Step 4: Run the compression script
python compress.py \
--output_dir ./compress_models \
--per_device_train_batch_size 32 \
--per_device_eval_batch_size 32 \
--num_train_epochs 4 \
--width_mult_list 0.75 \
--batch_size_list 4 8 16 \
--batch_num_list 1 \
```
Below, the hyperparameters that can be passed to the model compression initiation command will be introduced.
<a name="CompressionArguments-Parameter-Introduction"></a>
#### CompressionArguments Parameter Introduction
The parameters in `CompressionArguments` are partly specific to model compression functionality, while another part is inherited from `TrainingArguments`, which are hyperparameters that need to be set during compression training. The following will provide a detailed introduction.
**Common Parameters**
The parameters in the common parameters section are independent of specific compression strategies.
- **--strategy** Model compression strategy, currently supports
`'dynabert+qat+embeddings'`, `'dynabert+qat'`, `'dynabert+embeddings'`, `'dynabert+ptq'`, `'dynabert'`, `'ptq'`, and `'qat'`. Here, `'dynabert'` represents the width pruning strategy based on DynaBERT, `'qat'` denotes Quantization Aware Training, `'ptq'` indicates Post-Training Quantization, and `'embeddings'` signifies vocabulary quantization. The `--strategy` option supports selecting any reasonable combination of these strategies. The default is `'dynabert+ptq'`.
- **--output_dir**: Directory to save the model after compression.
- **--input_infer_model_path**: Path to the static graph model to be compressed. This parameter is intended to support the compression of static graph models. It can be ignored if not needed. The default is `None`.
- **--input_dtype**: Input type for the exported model, typically `int64` or `int32`. The default is `int64`.
**DynaBERT Pruning Parameters**
When the user employs DynaBERT pruning or PTQ quantization strategies (i.e., when the strategy includes 'dynabert' or 'qat'), the following optional parameters need to be provided:
- **--width_mult_list**: A search list for the retained width during pruning. For a 6-layer model, `3/4` is recommended, and for a 12-layer model, `2/3` is recommended. This indicates the retention ratio of the `q`, `k`, `v`, and `ffn` weight widths. For instance, if a 12-layer model originally has 12 attention heads, it will have only 9 attention heads after pruning. The default is `[3/4]`.
- **--per_device_train_batch_size**: Batch size per GPU/CPU core for pruning training. The default is 8.
- **--per_device_eval_batch_size**: Batch size per GPU/CPU core for pruning evaluation. The default is 8.
- **--num_train_epochs**: Number of epochs required for pruning training. The default is 3.0.
- **--max_steps**: If set to a positive number, it indicates the total number of training steps to execute. This overrides `num_train_epochs`.
- **--logging_steps**: The number of update steps between two logs. Default is 500.
- **--save_steps**: The number of steps for evaluating the model. Default is 100.
- **--optim**: The name of the optimizer used for pruning training, default is 'adamw'.
- **--learning_rate**: The initial learning rate for the optimizer used in pruning training. Default is 5e-05.
- **--weight_decay**: The weight decay value applied to all layers during pruning training, except for all bias and LayerNorm weights. Default is 0.0.
- **--adam_beta1**: The beta1 hyperparameter for the AdamW optimizer used in pruning training. Default is 0.9.
- **--adam_beta2**: The beta2 hyperparameter for the AdamW optimizer used in pruning training. Default is 0.999.
- **--adam_epsilon**: The epsilon hyperparameter for the AdamW optimizer used in pruning training. Default is 1e-8.
- **--max_grad_norm**: The maximum gradient norm (used for gradient clipping). Default is 1.0.
- **--lr_scheduler_type**: The learning rate scheduling strategy to use. Default is 'linear'.
- **--warmup_ratio**: The proportion of total training steps used for linear warmup from 0 to `learning_rate`. Default is 0.0.
- **--warmup_steps**: The number of steps used for linear warmup from 0 to `learning_rate`. Overrides the warmup_ratio parameter. Default is 0.
- **--seed**: The random seed set to ensure reproducibility across multiple runs. Default is 42.
- **--device**: The name of the device to run on. Supports cpu/gpu. Default is 'gpu'.
- **--remove_unused_columns**: Whether to remove unused field data from the Dataset. Default is True.
**Quantization Common Parameters**
**PTQ Quantization Parameters**
When the user employs the PTQ quantization strategy, the following optional parameters need to be provided:
- **--algo_list**: The list of quantization strategy searches, currently supporting `'KL'`, `'abs_max'`, `'min_max'`, `'avg'`, `'hist'`, `'mse'`, and `'emd'`. Different strategies calculate the quantization scale factor differently. It is recommended to provide multiple strategies to obtain multiple quantized models produced by various strategies, from which the optimal model can be selected. ERNIE models are recommended to use strategies like `'hist'`, `'mse'`, `'KL'`, and `'emd'`. Default is ['mse', 'KL'].
- **--batch_num_list**: The hyperparameter search list for batch_nums, where batch_nums indicates the number of batches required for sampling. The total amount of calibration data is batch_size * batch_nums. If batch_num is None, all data provided by the data loader will be used as calibration data. Default is [1].
- **--batch_size_list**: The search list for the batch_size of calibration samples. Bigger is not always better; it is also a hyperparameter. It is recommended to provide multiple calibration sample sizes, and the optimal model can be selected from multiple quantized models. Default is `[4]`.
- **--weight_quantize_type**: The quantization type for weights, supporting `'abs_max'` and `'channel_wise_abs_max'`.
Two methods. Typically, 'channel_wise_abs_max' is used, as this method usually results in a model with higher accuracy.
- **activation_quantize_type**: The quantization type for activation tensors. Supports 'abs_max', 'range_abs_max', and 'moving_average_abs_max'. In the 'ptq' strategy, the default is 'range_abs_max'.
- **--round_type**: The method for converting weight values from FP32 to INT8. Currently supports `'round'` and '[adaround](https://arxiv.org/abs/2004.10568)', with the default being `'round'`.
- **--bias_correction**: If set to True, it indicates the use of [bias correction](https://arxiv.org/abs/1810.05723) functionality, with the default being False.
**QAT Quantization Parameters**
When the user employs the QAT quantization strategy, in addition to setting the above training-related parameters, the following optional parameters can also be provided:
- **--weight_quantize_type**: The quantization type for weights, supporting both `'abs_max'` and `'channel_wise_abs_max'`. Typically, 'channel_wise_abs_max' is used, as this method usually results in a model with higher accuracy.
- **activation_quantize_type**: The quantization type for activation tensors. Supports 'abs_max', 'range_abs_max', and 'moving_average_abs_max'. In the 'qat' strategy, it defaults to 'moving_average_abs_max'.
- **use_pact**: Whether to use the PACT quantization strategy, which is an improvement over the standard method. Refer to the paper [PACT: Parameterized Clipping Activation for Quantized Neural Networks](https://arxiv.org/abs/1805.06085). When enabled, it results in higher accuracy, with the default being True.
- **moving_rate**: The decay coefficient in the 'moving_average_abs_max' quantization method, with a default value of 0.9.

## Model Evaluation and Deployment
Pruned and quantized models can no longer be loaded using `from_pretrained`.
Importing for prediction is not sufficient; instead, you must use Paddle deployment tools to complete the prediction.
For deploying the compressed model, refer to the [deployment documentation](../../slm/model_zoo/ernie-3.0/deploy).
### Python Deployment
Server-side deployment can begin here. You may refer to [seq_cls_infer.py](../../slm/model_zoo/ernie-3.0/deploy/python/seq_cls_infer.py) or [token_cls_infer.py](../../slm/model_zoo/ernie-3.0/deploy/python/token_cls_infer.py) to write your own prediction script. Follow the instructions in the [Python Deployment Guide](../../slm/model_zoo/ernie-3.0/deploy/python/README.md) to set up the prediction environment, evaluate the accuracy of the compressed model, conduct performance testing, and deploy.

<a name="FAQ"></a>
## FAQ
**Q: Does model compression require data?**
A: DynaBERT pruning and quantization-aware training (QAT) require the training set for training and the validation set for evaluation, similar to fine-tuning. Static offline quantization (PTQ) only requires the validation set (with a low sample size requirement, typically 4-16 samples may suffice).
**Q: The example code uses built-in datasets. How can I use my own data?**
A: You can refer to the UIE example or the [datasets custom dataset loading documentation](https://huggingface.co/docs/datasets/loading).
**Q: Can the compressed model continue training?**
A: Model compression is primarily for inference acceleration, so compressed models are static graph (prediction) models and cannot be imported for continued training using the `from_pretrained()` API.
**Q: How to choose between pruning and quantization?**
A: You can set the parameter `--strategy` to choose the compression strategy. By default, both pruning and quantization are selected, with pruning preceding quantization. Currently, the pruning strategy involves a training process that requires downstream task training data, and the training time depends on the data volume of the downstream task, comparable to fine-tuning. Static offline quantization does not require additional training and is faster; generally, quantization offers more significant acceleration than pruning. It is recommended to choose both pruning and quantization, as this may yield better results than quantization alone in some cases.
**Q: Is there a training process in pruning?**
A: DynaBERT pruning is similar to the distillation process and involves hyperparameters used during model training. For convenience, you can directly use the best hyperparameters from fine-tuning. To further improve accuracy, you can perform a Grid Search on hyperparameters such as `batch_size`, `learning_rate`, and `epoch`.
**Q: Why does using a `TensorDataset` object for quantization result in an error?**
A: When using quantization, the `eval_dataset` cannot be a `TensorDataset` object because the quantization function executes in static graph mode internally, and `TensorDataset`
Can only be used under dynamic graphs; using both simultaneously will cause errors.

# PaddleNLP Data API
This module provides common APIs for constructing effective data processing pipelines in NLP tasks.
## API List
| API | Description |
| ------------------------------- | :------------------------------------------- |
| `paddlenlp.data.Stack` | Stack N input data with the same shape to build a batch |
| `paddlenlp.data.Pad` | Stack N input data to build a batch, each input will be padded to the maximum length among the N inputs |
| `paddlenlp.data.Tuple` | Wrap multiple batchify functions together to form a tuple |
| `paddlenlp.data.Dict` | Wrap multiple batchify functions together to form a dict |
| `paddlenlp.data.SamplerHelper` | Build iterable sampler for `Dataloader` |
| `paddlenlp.data.Vocab` | Map between text tokens and IDs |
| `paddlenlp.data.JiebaTokenizer` | Jieba tokenizer |
## API Usage
The above APIs are all used to assist in building `DataLoader`. The three important initialization parameters of `DataLoader` are `dataset`, `batch_sampler`, and `collate_fn`.
`paddlenlp.data.Vocab` and `paddlenlp.data.JiebaTokenizer` are used when constructing `dataset` to handle the mapping between text tokens and IDs.
`paddlenlp.data.SamplerHelper` is used to build an iterable `batch_sampler`.
`paddlenlp.data.Stack`, `paddlenlp.data.Pad`, `paddlenlp.data.Tuple`, and `paddlenlp.data.Dict` are used to build the `collate_fn` function that generates mini-batches.
### Data Preprocessing
#### `paddlenlp.data.Vocab`
The `paddlenlp.data.Vocab` class is a vocabulary that includes a series of methods for mapping between text tokens and IDs. It supports building vocabulary from files, dictionaries, json, and other sources.
```python
from paddlenlp.data import Vocab
# Build from file
vocab1 = Vocab.load_vocabulary(vocab_file_path)
# Build from dictionary
# dic = {'unk':0, 'pad':1, 'bos':2, 'eos':3, ...}
vocab2 = Vocab.from_dict(dic)
# Build from json (usually for restoring previously saved Vocab objects from json_str or json files)
# json_str method
json_str = vocab1.to_json()
vocab3 = Vocab.from_json(json_str)
# json file method
vocab1.to_json(json_file_path)
vocab4 = Vocab.from_json(json_file_path)
```
#### `paddlenlp.data.JiebaTokenizer`
`paddlenlp.data.JiebaTokenizer` requires initializing with a `paddlenlp.data.Vocab` class, containing the `cut` tokenization method and the `encode` method for converting plain text sentences to ids.
```python
from paddlenlp.data import Vocab, JiebaTokenizer
# Vocabulary file path (download the vocabulary file first when running the sample)
# wget https://bj.bcebos.com/paddlenlp/data/senta_word_dict.txt
vocab_file_path = './senta_word_dict.txt'
# Build vocabulary
vocab = Vocab.load_vocabulary(
vocab_file_path,
unk_token='[UNK]',
pad_token='[PAD]')
tokenizer = JiebaTokenizer(vocab)
tokens = tokenizer.cut('I love you, China') # ['I love you', 'China']
ids = tokenizer.encode('I love you, China') # [1170578, 575565]
```
### Building `Sampler`
#### `paddlenlp.data.SamplerHelper`
`paddlenlp.data.SamplerHelper` serves to build iterable samplers for `DataLoader`, containing methods like `shuffle`, `sort`, `batch`, `shard`, etc., providing flexible usage for users.
```python
from paddlenlp.data import SamplerHelper
from paddle.io import Dataset
class MyDataset(Dataset):
def __init__(self):
super(MyDataset, self).__init__()
self.data = [
[[1, 2, 3, 4], [1]],
[[5, 6, 7], [0]],
[[8, 9], [1]],
]
def __getitem__(self, index):
data = self.data[index][0]
label = self.data[index][1]
return data, label
def __len__(self):
return len(self.data)
dataset = MyDataset()
# SamplerHelper returns an iterable of data indices, generated indices: [0, 1, 2]
sampler = SamplerHelper(dataset)
# `shuffle()` randomly shuffles the index order, generated indices: [0, 2, 1]
sampler = sampler.shuffle()
# sort() arranges indices based on specified key within buffer_size samples
# Example: sort by length of the first field in ascending order, generated indices: [2, 0, 1]
key = (lambda x, data_source: len(data_source[x][0]))
sampler = sampler.sort(key=key, buffer_size=2)
# batch() creates mini-batches according to batch_size, generated indices: [[2, 0], [1]]
sampler = sampler.batch(batch_size=2)
# shard() splits dataset for multi-GPU training, current GPU indices: [[2, 0]]
sampler = sampler.shard(num_replicas=2)
```
### Constructing `collate_fn`
#### `paddlenlp.data.Stack`
`paddlenlp.data.Stack` is used to create batches. Its inputs must have identical shapes, and the output is a batch formed by stacking these inputs.
```python
from paddlenlp.data import Stack
a = [1, 2, 3, 4]
b = [3, 4, 5, 6]
c = [5, 6, 7, 8]
result = Stack()([a, b, c])
"""
[[1, 2, 3, 4],
[3, 4, 5, 6],
[5, 6, 7, 8]]
"""
```
#### `paddlenlp.data.Pad`
`paddlenlp.data.Pad` is used to create batches. It first pads all input data to the maximum length, then stacks them to form batch data.
```python
from paddlenlp.data import Pad
a = [1, 2]
b = [3, 4, 5]
c = [6, 7, 8, 9]
result = Pad(pad_val=0)([a, b, c])
"""
[[1, 2, 0, 0],
[3, 4, 5, 0],
[6, 7, 8, 9]]
"""
```
```python
from paddlenlp.data import Pad
a = [1, 2, 3, 4]
b = [5, 6, 7]
c = [8, 9]
result = Pad(pad_val=0)([a, b, c])
"""
[[1, 2, 3, 4],
[5, 6, 7, 0],
[8, 9, 0, 0]]
"""
```
#### `paddlenlp.data.Tuple`
`paddlenlp.data.Tuple` wraps multiple batch functions together into a tuple.
```python
from paddlenlp.data import Stack, Pad, Tuple
data = [
[[1, 2, 3, 4], [1]],
[[5, 6, 7], [0]],
[[8, 9], [1]],
]
batchify_fn = Tuple(Pad(pad_val=0), Stack())
ids, label = batchify_fn(data)
"""
ids:
[[1, 2, 3, 4],
[5, 6, 7, 0],
[8, 9, 0, 0]]
label: [[1], [0], [1]]
"""
```
#### `paddlenlp.data.Dict`
`paddlenlp.data.Dict` wraps multiple batch functions together into a dictionary.
```python
from paddlenlp.data import Stack, Pad, Dict
data = [
{'labels':[1], 'token_ids':[1, 2, 3, 4]},
{'labels':[0], 'token_ids':[5, 6, 7]},
{'labels':[1], 'token_ids':[8, 9]},
]
batchify_fn = Dict({'token_ids':Pad(pad_val=0), 'labels':Stack()})
ids, label = batchify_fn(data)
"""
ids:
[[1, 2, 3, 4],
[5, 6, 7, 0],
[8, 9, 0, 0]]
label: [[1], [0], [1]]
"""
```
### Comprehensive Example
```python
from paddlenlp.data import Vocab, JiebaTokenizer, Stack, Pad, Tuple, SamplerHelper
from paddlenlp.datasets import load_dataset
from paddle.io import DataLoader
# Vocabulary file path, example program needs to download vocabulary file first
# wget https://bj.bcebos.com/paddlenlp/data/senta_word_dict.txt
vocab_file_path = './senta_word_dict.txt'
# Build vocabulary
vocab = Vocab.load_vocabulary(
vocab_file_path,
unk_token='[UNK]',
pad_token='[PAD]')
# Initialize tokenizer
tokenizer = JiebaTokenizer(vocab)
def convert_example(example):
text, label = example['text'], example['label']
ids = tokenizer.encode(text)
label = [label]
return ids, label
dataset = load_dataset('chnsenticorp', splits='train')
dataset = dataset.map(convert_example, lazy=True)
pad_id = vocab.token_to_idx[vocab.pad_token]
batchify_fn = Tuple(
Pad(axis=0, pad_val=pad_id), # ids
Stack(dtype='int64') # label
)
batch_sampler = SamplerHelper(dataset).shuffle().batch(batch_size=16)
data_loader = DataLoader(
dataset,
batch_sampler=batch_sampler,
collate_fn=batchify_fn,
return_list=True)
# Test dataset
for batch in data_loader:
ids, label = batch
print(ids.shape, label.shape)
print(ids)
print(label)
break
```

Data Processing
================
Datasets typically contain raw data, which requires specific processing and sampling to form batches. These are then fed through :class:`paddle.io.DataLoader` for training or inference. PaddleNLP provides corresponding functionalities to support each step in this pipeline.
Data Processing Based on Pretrained Models
------------------------------------------
When using pretrained models for NLP tasks, loading the corresponding Tokenizer is essential. PaddleNLP's :class:`PreTrainedTokenizer` implements basic data processing capabilities through its built-in :func:`__call__` method. All pretrained model Tokenizers in PaddleNLP inherit from :class:`PreTrainedTokenizer`. Here's an example using BertTokenizer:
.. code-block::
from paddlenlp.transformers import BertTokenizer
tokenizer = BertTokenizer.from_pretrained('bert-base-chinese')
# Single sentence conversion (single data instance)
print(tokenizer(text='天气不错')) # {'input_ids': [101, 1921, 3698, 679, 7231, 102], 'token_type_ids': [0, 0, 0, 0, 0, 0]}
# Sentence pair conversion (single data instance)
print(tokenizer(text='天气',text_pair='不错')) # {'input_ids': [101, 1921, 3698, 102, 679, 7231, 102], 'token_type_ids': [0, 0, 0, 0, 1, 1, 1]}
# Single sentence conversion (multiple data instances)
print(tokenizer(text=['天气','不错'])) # [{'input_ids': [101, 1921, 3698, 102], 'token_type_ids': [0, 0, 0, 0]},
# {'input_ids': [101, 679, 7231, 102], 'token_type_ids': [0, 0, 0, 0]}]
For additional parameters and functionalities of the :func:`__call__` method, please refer to PreTrainedTokenizer.
The :func:`map` method in PaddleNLP's built-in :class:`paddlenlp.datasets.MapDataset` supports applying a function to uniformly transform dataset entries. Below we demonstrate this using :obj:`LCQMC`
Take the data processing pipeline of `LCQMC` as an example:
.. code-block::
from paddlenlp.transformers import BertTokenizer
from paddlenlp.datasets import load_dataset
tokenizer = BertTokenizer.from_pretrained('bert-base-chinese')
train_ds = load_dataset('lcqmc', splits='train')
print(train_ds[0]) # {'query': '喜欢打篮球的男生喜欢什么样的女生', 'title': '爱打篮球的男生喜欢什么样的女生', 'label': 1}
As can be seen, :obj:`LCQMC` is a sentence pair matching task, i.e., a 2-classification task to determine whether two sentences are semantically similar. We need to process the text data with keys **query** and **title**. We will implement a data processing function based on :class:`PreTrainedTokenizer` and pass it to the dataset's :func:`map` method.
.. code-block::
def convert_example(example, tokenizer):
tokenized_example = tokenizer(
text=example['query'],
text_pair=example['title'])
# Add label for training
tokenized_example['label'] = [example['label']]
return tokenized_example
from functools import partial
trans_func = partial(
convert_example,
tokenizer=tokenizer)
train_ds.map(trans_func)
print(train_ds[0]) # {'input_ids': [101, 1599, 3614, 2802, 5074, 4413, 4638, 4511, 4495,
# 1599, 3614, 784, 720, 3416, 4638, 1957, 4495, 102,
# 4263, 2802, 5074, 4413, 4638, 4511, 4495, 1599, 3614,
# 784, 720, 3416, 4638, 1957, 4495, 102],
# 'token_type_ids': [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
# 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
# 'label': [1]}
As can be seen, the text data in the dataset has been processed into *features* that the model can accept.
The :func:`map` method has an important parameter :attr:`batched`. When set to :obj:`True` (default is :obj:`False`), the data processing function :func:`trans_func`
.. code-block::
def convert_examples(examples, tokenizer):
queries = [example['query'] for example in examples]
titles = [example['title'] for example in examples]
tokenized_examples = tokenizer(text=queries, text_pair=titles, return_dict=False)
# Add label for training
for idx in range(len(tokenized_examples)):
tokenized_examples[idx]['label'] = [examples[idx]['label']]
return tokenized_examples
from functools import partial
trans_func = partial(convert_examples, tokenizer=tokenizer)
train_ds.map(trans_func, batched=True)
print(train_ds[0]) # {'input_ids': [101, 1599, 3614, 2802, 5074, 4413, 4638, 4511, 4495,
# 1599, 3614, 784, 720, 3416, 4638, 1957, 4495, 102,
# 4263, 2802, 5074, 4413, 4638, 4511, 4495, 1599, 3614,
# 784, 720, 3416, 4638, 1957, 4495, 102],
# 'token_type_ids': [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
# 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
# 'label': [1]}
As can be seen, the results of the two implementations in this example are the same. However, in tasks such as machine reading comprehension and dialogue, where a single raw data instance may generate multiple *features* (refer to `run_squad.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/examples/machine_reading_comprehension/SQuAD/run_squad.py>`__), it is usually necessary to set the :attr:`batched` parameter to :obj:`True`.
:func:`map
The :func:`map` method also has a :attr:`num_workers` parameter. When it's greater than 0, multi-process data processing will be enabled, which can improve processing speed. However, please note that if the data processing function uses information related to **data index**, multi-processing may lead to incorrect results.
For other parameters of the :func:`map` method and other data processing methods of :class:`paddlenlp.datasets.MapDataset`, please refer to :doc:`dataset <../source/paddlenlp.datasets.dataset>`.
Batchify
-----------
PaddleNLP provides various built-in collate functions that work with :class:`paddle.io.BatchSampler` to simplify batch creation.
Let's continue with the :obj:`LCQMC` data processing example. As shown in the previous section, each processed data sample is a **dictionary** containing three keys: `input_ids`, `token_type_ids`, and `label`.
Among these, `input_ids` and `token_type_ids` need to be **padded** before being fed into the model, while `label` needs to be **stacked** before being passed to the loss function.
Therefore, we use PaddleNLP's built-in :func:`Dict`, :func:`Stack`, and :func:`Pad` functions to organize batch data. The final :func:`batchify_fn` is as follows:
.. code-block::
from paddlenlp.data import Dict, Stack, Pad
# Use Dict to match Pad/Stack functions with dictionary keys
train_batchify_fn = lambda samples, fn=Dict({
'input_ids': Pad(axis=0, pad_val=tokenizer.pad_token_id),
'token_type_ids': Pad(axis=0, pad_val=tokenizer.pad_token_type_id),
'label': Stack(dtype="int64")
}): fn(samples)
Then we use :class:`paddle.io.BatchSampler` and :func:`batchify_fn` to build :class:`paddle.io.DataLoader`:
.. code-block::
from paddle.io import DataLoader, BatchSampler
train_batch_sampler = BatchSampler(train_ds, batch_size=2, shuffle=True)
train_data_loader = DataLoader(dataset=train_ds, batch_sampler=train_batch_sampler, collate_fn=train_batchify_fn)
This completes the entire data preparation pipeline. For more batchify methods, please refer to :doc:`collate <../source/paddlenlp.data.collate>`.
.. note::
- When performing **single-machine multi-GPU** training, replace :class:`BatchSampler` with :class:`DistributedBatchSampler`. For more information about :class:`paddle.io.BatchSampler`, please refer to `BatchSampler <https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/fluid/dataloader/batch_sampler/BatchSampler_cn.html>`_.
- For more complex batching functionalities such as in-batch sorting or token-based batching, you can use PaddleNLP's built-in :class:`SamplerHelper`. Example usage can be found in `reader.py <https://github.com/PaddlePaddle/PaddleNLP/blob/develop/examples/machine_translation/transformer/reader.py>`__.
Data Processing Based on Non-Pretrained Models
-----------------------------------------------
When using non-pretrained models for NLP tasks, we can leverage PaddleNLP's built-in :class:`JiebaTokenizer` and :class:`Vocab` for data processing. The overall workflow is similar to using pretrained models. We demonstrate this using the Chinese sentiment analysis dataset :obj:`ChnSentiCorp`:
.. code-block::
from paddlenlp.data import JiebaTokenizer, Vocab
from paddlenlp.datasets import load_dataset
train_ds = load_dataset('chnsenticorp', splits='train')
print(train_ds[0]) # {'text': '选择珠江花园的原因就是方便，有电动扶梯直接到达海边，周围餐馆、食廊、商场、超市、摊位一应俱全。
# 酒店装修一般，但还算整洁。 泳池在大堂的屋顶，因此很小，不过女儿倒是喜欢。 包的早餐是西式的，还算丰富。
# 服务吗，一般', 'label': 1}
# Build Vocab from local vocab file
vocab = Vocab.load_vocabulary('./senta_word_dict.txt', unk_token='[UNK]', pad_token='[PAD]')
# Initialize JiebaTokenizer with Vocab
tokenizer = JiebaTokenizer(vocab)
.. note::
- In addition to initializing from a local vocabulary file, :class:`Vocab` provides multiple initialization methods, including creating from :class:`dictionary` and datasets. For details, refer to the Vocab documentation.
- Besides the built-in :class:`JiebaTokenizer`, users can implement custom tokenization approaches or use third-party libraries, then convert tokens to indices via :func:`Vocab.to_indices`.
The `convert_example` method converts tokens to ids.
Following similar data processing flow as pre-trained model based approaches, we write data processing functions and pass them to the :func:`map` method:
.. code-block::
def convert_example(example, tokenizer):
input_ids = tokenizer.encode(example["text"])
valid_length = [len(input_ids)]
label = [example["label"]]
return input_ids, valid_length, label
trans_fn = partial(convert_example, tokenizer=tokenizer)
train_ds.map(trans_fn)
print(train_ds[0]) # ([417329, 128448, 140437, 173188, 118001, 213058, 595790, 1106339, 940533, 947744, 169206,
# 421258, 908089, 982848, 1106339, 35413, 1055821, 4782, 377145, 4782, 238721, 4782, 642263,
# 4782, 891683, 767091, 4783, 672971, 774154, 1250380, 1106339, 340363, 146708, 1081122,
# 4783, 1, 943329, 1008467, 319839, 173188, 909097, 1106339, 1010656, 261577, 1110707,
# 1106339, 770761, 597037, 1068649, 850865, 4783, 1, 993848, 173188, 689611, 1057229, 1239193,
# 173188, 1106339, 146708, 427691, 4783, 1, 724601, 179582, 1106339, 1250380],
# [67],
# [1])
We can observe that the raw data has been processed into *features*. However, here we notice that a single data entry is not a **dictionary** but a **tuple**. Therefore, our :func:`batchify_fn` needs to be adjusted accordingly.
.. code-block::
from paddlenlp.data import Tuple, Stack, Pad
# Use Tuple function to align Pad, Stack etc. functions with key-value pairs in data
train_batchify_fn = lambda samples, fn=Tuple((
Pad(axis=0, pad_val=vocab.token_to_idx.get('[PAD]', 0)), # input_ids
Stack(dtype="int64"), # seq len
Stack(dtype="int64") # label
)): fn(samples)
It can be observed that the :func:`Dict` function maps the key-values in individual data instances to corresponding :func:`Pad` etc. functions, which is suitable when each data instance is a dictionary. Whereas :func:`Tuple` aligns different components through indices in individual data instances.
Therefore, special attention should be paid to the correspondence between the :func:`convert_example` method and the :func:`batchify_fn` method.
The subsequent workflow remains consistent with the data processing approach based on pretrained models.

Loading Datasets
============
Quickly Load Built-in Datasets
------------------------------
PaddleNLP currently provides 20+ built-in NLP datasets covering tasks like reading comprehension, text classification, sequence labeling, machine translation, etc. All available datasets can be found in :doc:`Dataset List <./dataset_list>`.
Take the **msra_ner** dataset as an example:
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> train_ds, test_ds = load_dataset("msra_ner", splits=("train", "test"))
The :func:`load_dataset` method will locate the corresponding data loading script for msra_ner dataset in :obj:`paddlenlp.datasets` (default path: paddlenlp/datasets/msra_ner.py), and call the relevant methods of the :class:`DatasetBuilder` class in the script to generate the dataset.
The generated dataset can be returned as either :class:`MapDataset` or :class:`IterDataset`, which are extensions of :class:`paddle.io.Dataset` and :class:`paddle.io.IterableDataset` respectively. Simply set the :attr:`lazy` parameter in :func:`load_dataset` to get the corresponding type. :obj:`False` returns :class:`MapDataset` while :obj:`True` returns :class:`IterDataset`. The default value is None, which returns the dataset type predefined by :class:`DatasetBuilder` (mostly :class:`MapDataset`).
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> train_ds = load_dataset("msra_ner", splits="train")
>>> print(type(train_ds))
<class 'paddlenlp.datasets.dataset.MapDataset'> # Default
>>> train_ds = load_dataset("msra_ner", splits="train", lazy=True)
>>> print(type(train_ds))
<class 'paddlenlp.datasets.dataset.IterDataset'>
For details about :class:`MapDataset` and :class:`IterDataset` features and differences, please refer to the API documentation :doc:`datasets <../source/paddlenlp.datasets.dataset>`.
Selecting Subsets
^^^^^^^^^^^^^^^^^
Some datasets are collections of multiple subsets, where each subset is an independent dataset. For example, the **GLUE** dataset contains 10 subsets like COLA, SST2, MRPC, QQP, etc.
The :func:`load_dataset` method provides a :attr:`name` parameter to specify subsets. For example, to load the SQuAD dataset from the XTREME benchmark:
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> squad_train = load_dataset('xtreme', name='squad', splits='train')
The data loading script will automatically add the ``name`` parameter to the dataset file path. For example, the files for the SQuAD subset are typically stored in the ``xtreme/squad`` directory.
The `splits` parameter is used to specify the subsets of the dataset to retrieve. Usage example:
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> train_ds, dev_ds = load_dataset("glue", name="cola", splits=("train", "dev"))
Reading Local Datasets in Built-in Dataset Format
-------------------------------------------------
Sometimes we may want to use local data that shares the same format as built-in datasets to replace some built-in data (e.g., for data augmentation in SQuAD competition training). The :func:`load_dataset` method's :attr:`data_files` parameter enables this functionality. Taking **SQuAD** as an example:
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> train_ds, dev_ds = load_dataset("squad", data_files=("my_train_file.json", "my_dev_file.json"))
>>> test_ds = load_dataset("squad", data_files="my_test_file.json")
.. note::
For some datasets, different splits may require different reading approaches. In such cases, corresponding split information must be provided in the :attr:`splits` parameter, which should **exactly match** the :attr:`data_files` entries.
In this scenario, :attr:`splits` no longer represents selected built-in datasets, but rather specifies the format for reading local data.
Here's an example using the **COLA** dataset:
.. code-block::
>>> from paddlenlp.datasets import load_dataset
>>> train_ds, test_ds = load_dataset("glue", "cola", splits=["train", "test"], data_files=["my_train_file.csv", "my_test_file.csv"])
**Important note:** The dataset has no default loading options - you must specify at least one of :attr:`splits` or :attr:`data_files`.

How to Customize a Dataset
============
By using :func:`load_dataset`, :class:`MapDataset`, and :class:`IterDataset` provided by PaddleNLP, anyone can easily define their own dataset.
Creating Dataset from Local Files
-------------------
When creating a dataset from local files, we **recommend** providing a reader function based on the local data format and passing it to :func:`load_dataset` to create the dataset.
.. code-block::
from paddlenlp.datasets import load_dataset
def read(data_path):
with open(data_path, 'r', encoding='utf-8') as f:
# Skip header
next(f)
for line in f:
words, labels = line.strip('\n').split('\t')
words = words.split('\002')
labels = labels.split('\002')
yield {'tokens': words, 'labels': labels}
# data_path is the parameter for read()
map_ds = load_dataset(read, data_path='train.txt', lazy=False)
iter_ds = load_dataset(read, data_path='train.txt', lazy=True)
We recommend writing data reading code as a generator, which better constructs both :class:`MapDataset` and :class:`IterDataset`. We also suggest formatting each data sample as a dictionary, which facilitates data flow monitoring.
In fact, :class:`MapDataset` can meet requirements in most cases. Generally, :class:`IterDataset` is only considered when the dataset is too large to be loaded into memory at once.
.. note::
Note that only PaddleNLP's built-in datasets support automatic label-to-id conversion (detailed conditions refer to :doc:`Creating DatasetBuilder <../community/contribute_datasets/how_to_write_a_DatasetBuilder>`).
For custom datasets like the above example, you need to manually add label-to-id functionality in your custom feature conversion method.
Parameters from custom data reader functions can be directly passed to :func:`load_dataset` as keyword arguments. For custom datasets, the :attr:`lazy` parameter is **required**.
Creating from :class:`paddle.io.Dataset/IterableDataset`
Creating a Dataset
-------------------
While PaddlePaddle's built-in :class:`Dataset` and :class:`IterableDataset` can be directly used with :class:`DataLoader` for model training, sometimes we need more convenient ways to perform data processing (e.g., convert to features, data cleaning, data augmentation). PaddleNLP's built-in :class:`MapDataset` and :class:`IterDataset` provide APIs to implement these functions.
If you're accustomed to using :class:`paddle.io.Dataset/IterableDataset` to create datasets, you can simply wrap them with :class:`MapDataset` or :class:`IterDataset` to convert them into PaddleNLP dataset objects.
Here's a simple example. The usage of :class:`IterDataset` is similar.
.. code-block::
from paddle.io import Dataset
from paddlenlp.datasets import MapDataset
class MyDataset(Dataset):
def __init__(self, path):
def load_data_from_source(path):
...
...
return data
self.data = load_data_from_source(path)
def __getitem__(self, idx):
return self.data[idx]
def __len__(self):
return len(self.data)
ds = MyDataset(data_path) # paddle.io.Dataset
new_ds = MapDataset(ds) # paddlenlp.datasets.MapDataset
Creating Dataset from Other Python Objects
-------------------
In theory, we can use any Python object containing :func:`__getitem__` and :func:`__len__` methods to create a :class:`MapDataset`, including :class:`List`, :class:`Tuple`, :class:`DataFrame`, etc. Simply pass the qualified Python object as initialization parameter to :class:`MapDataset`.
.. code-block::
from paddlenlp.datasets import MapDataset
data_source_1 = [1,2,3,4,5]
data_source_2 = ('a', 'b', 'c', 'd')
list_ds = MapDataset(data_source_1)
tuple_ds = MapDataset(data_source_2)
print(list_ds[0]) # 1
print(tuple_ds[0]) # a
Similarly, we can create :class:`IterDataset` using Python objects containing :func:`__iter__` method, such as :class:`List` and :class:`Generator`. The creation method is the same as :class:`MapDataset`.
.. code-block::
from paddlenlp.datasets import IterDataset
data_source_1 = ['a', 'b', 'c', 'd']
data_source_2 = (i for i in range(5))
list_ds = IterDataset(data_source_1)
gen_ds = IterDataset(data_source_2)
print([data for data in list_ds]) # ['a', 'b', 'c', 'd']
print([data for data in gen_ds]) # [0, 1, 2, 3, 4]
.. note::
Note that when passing a **generator** object to :class:`IterDataset` as shown in the above example, the dataset will automatically reset the generator when iterating over it for the second time. To reuse the generated data, you need to convert the generator to a list first.
The dataset generated by `IterDataset` can only be iterated **once**.
Like regular Python objects, as long as the above conditions are met, we can use the same method to create PaddleNLP datasets from third-party datasets.
For example, HuggingFace Dataset:
.. code-block::
from paddlenlp.datasets import MapDataset
from datasets import load_dataset
hf_train_ds = load_dataset('msra_ner', split='train')
print(type(train_ds)) # <class 'datasets.arrow_dataset.Dataset'>
train_ds = MapDataset(train_ds)
print(type(train_ds)) # <class 'paddlenlp.datasets.dataset.MapDataset'>
print(train_ds[2]) # {'id': '2',
# 'ner_tags': [0, 0, 0, 5, 0, 0, 5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
# 0, 0, 0, 0, 0, 0, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0],
# 'tokens': ['因', '有', '关', '日', '寇', '在', '京', '掠', '夺', '文', '物',
# '详', '情', '，', '藏', '界', '较', '为', '重', '视', '，', '也',
# '是', '我', '们', '收', '藏', '北', '京', '史', '料', '中', '的',
# '要', '件', '之', '一', '。']}
hf_train_ds = load_dataset('cmrc2018', split='train')
train_ds = MapDataset(hf_train_ds)
print(train_ds[1818]) # {'answers': {'answer_start': [9], 'text': ['字仲可']},
# 'context': '徐珂（），原名昌，字仲可，浙江杭县（今属杭州市）人。光绪举人。

Overview
============
Datasets and data processing are among the most critical components in NLP tasks. To help users complete this phase with lower learning costs, PaddleNLP offers the following features:
- **Powerful APIs**: Assist users in handling data processing workflows for most common NLP tasks.
- **Flexible Encapsulation**: Maintains low coupling and high cohesion between modules, allowing users to meet specific data processing requirements through inheritance and customization.
- **Built-in Datasets**: Cover most NLP tasks, paired with concise and easy-to-use dataset loading protocols and contribution guidelines. More friendly for beginners and community contributors.
Core APIs
----------
- :func:`load_dataset`: A quick dataset loading interface that generates datasets by calling methods of :class:`DatasetBuilder` subclasses with dataset reader script names and other parameters. For detailed instructions, refer to :doc:`Loading Datasets <./dataset_load>`.
- :class:`DatasetBuilder`: A base class inherited by all built-in datasets. Its main functionality includes downloading dataset files and generating Dataset objects. Most methods are encapsulated and not exposed to contributors. Contributors can submit datasets to the community by overriding methods like :func:`_get_data` and :func:`_read`. For details, see :doc:`How to Contribute Datasets </community/contribute_dataset>`.
- :class:`MapDataset/IterDataset`: Built-in dataset types in PaddleNLP, extending :class:`paddle.io.Dataset` and :class:`paddle.io.IterableDataset` respectively. They include NLP-specific data processing features like :func:`map` and :func:`filter`, and help users easily create custom datasets. Refer to *** and :doc:`How to Create Custom Datasets <./dataset_self_defined>` for more information.
Data Processing Workflow Design
-------------------------------
The general data processing workflow in PaddleNLP is as follows:
1. Load dataset (built-in or custom dataset, returning **raw data**).
2. Define :func:`trans_func` (including tokenization, token-to-ID conversion, etc.) and apply it via the dataset's :func:`map` method to convert raw data into *features*.
3. Define **batchify** methods and :class:`BatchSampler` based on the processed data.
4. Define :class:`DataLoader` with :class:`BatchSampler` and :func:`batchify_fn`.
Below is the data processing flowchart for a BERT-based text classification task:

## Dialogue Generation Template
PaddleNLP supports mainstream LLM dialogue models and automatically constructs multi-turn conversations through the following scripts.
### Using Dialogue Templates
```python
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("THUDM/chatglm-6b-v1.1")
# Single-round conversation
query = "What's fun to do in Beijing"
inputs = tokenizer.apply_chat_template(query, return_tensors="pd")
# Multi-round conversation
query = [["1+1=", "1+1=2"], ["Add one more"]]
inputs = tokenizer.apply_chat_template(query, return_tensors="pd")
```
### Customizing Dialogue Templates
Before explaining how to customize dialogue templates, let's clarify the construction logic: `final_query = system + conversation_history + query`.
* system: Fixed text at the beginning of the final prompt, e.g., "You are an AI assistant with a witty sense of humor, typically preferring to communicate in a literary style."
* conversation_history: Constructs multi-turn dialogues into a query, with different models potentially having different construction rules.
* query: The user's latest input.
Creating custom dialogue templates is straightforward - just create a `chat_template.json` file as follows:
1. Create chat_template file
> Default filename: `chat_template.json`
```json
{
"system": "You are an AI assistant with a witty sense of humor, typically preferring to communicate in a literary style.",
"conversation": ["[Round {{index}}]\nQuestion: {{user}}\n", "Answer: {{bot}}\n"],
"query": "[Round {{index}}]\nQuestion: {{query}}\nAnswer:"
}
```
Parameter description:
* The configuration file mainly contains three fields: `system`, `conversation`, `query`.
* `system`: Fixed text prepended to the final prompt. Typically not involved in loss computation during training.
* `conversation`: Multi-turn dialogue configuration, which must contain two templates: [user-template, bot-template], corresponding to the user query and model response configurations respectively. Used in both training and inference stages.
* `query`: Construction of the user's latest query, with configuration similar to `conversation`, typically used only during inference.
2. Loading custom dialogue templates via tokenizer
Two loading methods:
* Place the `chat_template.json` file in the model weights directory and load automatically via `Tokenizer.from_pretrained("/path/")`.
* Manual loading: Initialize the tokenizer first, then load via `tokenizer.init_chat_template(/path/to/file)`.
3. Using dialogue templates
```python
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("THUDM/chatglm-6b-v1.1")
# Only return the concatenated text
query = "What are some fun things to do in Beijing"
full_query = tokenizer.apply_chat_template(query, tokenize=False)
# Decode the concatenated text
inputs = tokenizer.apply_chat_template(query, tokenize=True, return_tensors="pd")
```

========
10-Minute Guide to High-Accuracy Chinese Sentiment Analysis
========
1. Install PaddleNLP
========
For installation procedures and troubleshooting, please refer to the [Installation Documentation](https://paddlenlp.readthedocs.io/en/latest/gettingstarted/install.html).
.. code-block::
>>> pip install --upgrade paddlenlp -i https://pypi.org/simple
2. One-Click Loading of Pretrained Models
========
Sentiment analysis is essentially a text classification task. PaddleNLP provides various pretrained models including ERNIE, BERT, RoBERTa, and Electra, along with fine-tuning networks for different downstream tasks. Let's use ERNIE as an example.
Load ERNIE model:
.. code-block::
>>> MODEL_NAME = "ernie-3.0-medium-zh"
>>> ernie_model = paddlenlp.transformers.ErnieModel.from_pretrained(MODEL_NAME)
Load text classification head:
.. code-block::
>>> model = paddlenlp.transformers.ErnieForSequenceClassification.from_pretrained(
... MODEL_NAME, num_classes=len(label_list))
3. Data Processing with Tokenizer
========
Load tokenizer:
.. code-block::
>>> tokenizer = paddlenlp.transformers.ErnieTokenizer.from_pretrained(MODEL_NAME)
Text processing example:
.. code-block::
>>> encoded_text = tokenizer(text="Please input test sample")
Convert to tensor:
.. code-block::
>>> input_ids = paddle.to_tensor([encoded_text['input_ids']])
>>> token_type_ids = paddle.to_tensor([encoded_text['token_type_ids']])
Model inference:
.. code-block::
>>> sequence_output, pooled_output = ernie_model(input_ids, token_type_ids)
>>> print(f"Token wise output: {sequence_output.shape}, Pooled output: {pooled_output.shape}")
4. Load Dataset
========
Load ChnSenticorp dataset:
.. code-block::
>>> train_ds, dev_ds, test_ds = paddlenlp.datasets.load_dataset(
... 'chnsenticorp', splits=['train', 'dev', 'test'])
Get label list:
.. code-block::
>>> label_list = train_ds.label_list
>>> print(label_list)
Sample data:
.. code-block::
>>> for idx in range(5):
... print(train_ds[idx])
5. Model Training and Evaluation
========
(Note: The original content ends here, so the translation stops accordingly while maintaining consistency.)
The :func:`paddle.io.DataLoader` interface asynchronously loads data with multi-threading, while configuring dynamic learning rates, loss functions, optimization algorithms, and evaluation metrics suitable for Transformer models like ERNIE.
The model training process typically follows these steps:
#. Fetch a batch of data from the dataloader.
#. Feed the batch data to the model for forward computation.
#. Pass the forward computation results to the loss function to calculate loss, and to evaluation metrics to compute performance metrics.
#. Perform backpropagation with the loss to update gradients. Repeat the above steps.
#. After each epoch, the program evaluates the model's current performance.
This example is also available on AIStudio for _online model training experience_.
.. _online model training experience: https://aistudio.baidu.com/aistudio/projectdetail/1294333
Finally, save the trained model for prediction.
6. Model Prediction
==================
After saving the trained model, define the prediction function :func:`predict` to perform sentiment analysis.
Example with custom prediction data and labels:
.. code-block::
>>> data = [
... 'This hotel is rather outdated, and the discounted rooms are mediocre. Overall average',
... 'Started watching with great excitement, but found a Mickey Mouse cartoon appearing after the main feature',
... 'As an established four-star hotel, the rooms remain well-kept and impressive. The airport shuttle service is excellent, allowing check-in during the ride to save time.',
... ]
>>> label_map = {0: 'negative', 1: 'positive'}
Prediction results:
.. code-block::
>>> results = predict(
... model, data, tokenizer, label_map, batch_size=batch_size)
>>> for idx, text in enumerate(data):
... print('Data: {} \t Label: {}'.format(text, results[idx]))
Data: This hotel is rather outdated, and the discounted rooms are mediocre. Overall average Label: negative
Data: Started watching with great excitement, but found a Mickey Mouse cartoon appearing after the main feature Label: negative
Data: As an established four-star hotel, the rooms remain well-kept and impressive. The airport shuttle service is excellent, allowing check-in during the ride to save time. Label: positive

# 🚣‍♂️ PaddlePaddle Large Model Suite 🚣
The PaddlePaddle Large Model Suite is designed with a one-stop experience,极致 performance, and ecosystem compatibility in mind. It aims to provide developers with comprehensive services including mainstream large model pretraining, fine-tuning (including SFT, PEFT technologies), alignment, quantization, and inference. Developers can quickly implement customized requirements for large language models in a convenient and low-cost manner.
<div align="center">
<img width="800" alt="llm" src="https://github.com/PaddlePaddle/PaddleNLP/assets/63761690/4e61647b-8d66-4870-ba45-77a57990523c">
</div>
## 💪🏼 Features of the Large Model Suite 💪🏼
- **PaddlePaddle 4D Parallel Distributed Strategy**. The PaddleNLP Trainer simplifies multi-hardware programming complexity through encapsulated support for PaddlePaddle's 4D parallel configuration - pure data parallelism, grouped parameter sharding data parallelism, tensor model parallelism, and pipeline model parallelism. Users can flexibly combine various distributed strategies during pretraining or fine-tuning by simply modifying Trainer configurations, fully leveraging the 4D parallel training capabilities of large models to significantly improve training performance across multiple models and hardware environments.
- **Efficient Fine-tuning and Alignment Strategies**. The suite provides multiple fine-tuning alignment methods including SFT, DPO, and RLHF. The self-developed Zero Padding optimization technique effectively reduces the proportion of invalid padding tokens in training data, further enhancing model training efficiency. Meanwhile, the innovative PEFT technology combined with low-bit and distributed parallel methods significantly reduces hardware requirements for large model fine-tuning and alignment.
- **Lossless Quantization for Large Models**. The suite pre-integrates PaddleSlim LLM.PTQ quantization algorithm and industry-adopted GPTQ and AWQ W4 quantization methods, successfully achieving lossless quantization processing for mainstream large models, notably accelerating model inference speed.
- **High-Performance Inference**. The high-performance inference module of the suite incorporates advanced strategies like dynamic insertion and full-cycle operator fusion, dramatically improving parallel inference speed. Simultaneously, the module hides underlying technical details, providing users with out-of-the-box high-performance parallel inference capabilities.

We provide more detailed documentation on [pretraining data preparation](./tools/preprocess), [Pretrain and custom datasets](https://paddlenlp.readthedocs.io/zh/latest/llm/dataset.html), [distributed strategy support](https://paddlenlp.readthedocs.io/zh/latest/llm/docs/pretrain.html#model-capability), and [performance test reports](https://paddlenlp.readthedocs.io/zh/latest/llm/docs/pretrain.html#model-performance). Refer to: [Large Model Pretraining Introduction](https://paddlenlp.readthedocs.io/zh/latest/llm/docs/pretrain.html), [Large Model Weight List](https://paddlenlp.readthedocs.io/zh/latest/llm/docs/pretrain.html#model-weight).
This project supports pretraining for large models such as LLaMA, GPT-3, BaiChuan, Qwen, and Mixtral. Users can switch configuration files to run different models with one click.
To facilitate user testing, this project provides processed 100k doc training samples:
```shell
# Download llama model data
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.bin
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.idx
# Download gpt model data
# wget https://bj.bcebos.com/paddlenlp/models/transformers/gpt/data/gpt2_openwebtext_100k.bin
# wget https://bj.bcebos.com/paddlenlp/models/transformers/gpt/data/gpt2_openwebtext_100k.idx
```
Organize all preprocessed files into a single directory for training:
```shell
mkdir data
mv llama_openwebtext_100k.bin ./data
mv llama_openwebtext_100k.idx ./data
```
Single-GPU training:
```shell
# Trainable with 16G VRAM
python -u run_pretrain.py ./config/qwen/pretrain_argument_0p5b.json
```
- This configuration requires 16G VRAM. Enable use_flash_attention, use_fused_rms_norm, and recompute to save VRAM.
- If the above configuration cannot be enabled or VRAM is still insufficient, enable `offload_optim` (requires ~11G VRAM):
`python -u run_pretrain.py ./config/qwen/pretrain_argument_0p5b.json --offload_optim 1`
High-performance multi-GPU and multi-node training:
```shell
# Compile custom operators (optional)
cd ../slm/model_zoo/gpt-3/external_ops/ && python3 setup.py install && cd -
# Multi-GPU pretraining reference:
python -u -m paddle.distributed.launch --devices "0,1,2,3,4,5,6,7" run_pretrain.py ./config/llama/pretrain_argument.json
# Multi-node training reference (requires ~45G VRAM):
python -u -m paddle.distributed.launch --devices "0,1,2,3,4,5,6,7" --master=192.168.1.1:8090 --nnodes=2 run_pretrain.py ./config/llama/pretrain_argument.json
```
- For detailed distributed launch commands, refer to [here](https://www.paddlepaddle.org.cn/documentation/docs/zh/2.6/api/paddle/distributed/launch_cn.html#launch).
Notes:
1. It is recommended to use the paddle develop version for training. Requires installation of...
`pip install fast_dataindex visualdl==2.5.3` and other missing whl packages
2. `use_flash_attention` requires A100 or higher machines, and it's recommended to use CUDA 11.8+ environment.
3. `use_fused_rms_norm` requires installation of custom operators. If the operator is still not found after installation, additional PYTHONPATH settings are required.
4. `continue_training` means loading training from an existing pre-trained model. The initial loss for the 7B model is approximately 2.xx, while the randomly initialized model's loss starts from 11.x and decreases.
5. For multi-machine training, if the training data files are located at the same path on all machines (e.g., when using shared storage), specify `--share_folder true` to have global card 0 create cached data. Otherwise, card 0 on each machine will create cached data independently by default.
6. If the default cache folder `index-cache/` exists in the dataset directory, the specified `--data_cache` will not take effect, and training will prioritize loading contents from the default cache folder.
### 2. Fine-tuning
PaddleNLP supports multiple SFT and PEFT fine-tuning strategies for mainstream large models, providing a unified and efficient fine-tuning solution:
- **Unified Training Entry**: The Paddle large model suite's fine-tuning solution can be adapted to mainstream large models. Users only need to modify configuration files to perform various large model fine-tuning on single or multiple cards (supports 4D parallel distributed strategies).
- **Efficient Data and Distributed Strategies**: The Zero Padding optimization strategy combined with FlashMask effectively improves model training efficiency. The original PEFT strategy combined with low-bit and distributed parallel strategies significantly reduces hardware requirements for large model fine-tuning, supporting single-card (A100 80G) 10B model fine-tuning and single-machine (A100 80G * 8) 100B model fine-tuning.
- **Support for Multi-turn Dialogue**: Supports unified dialogue templates and efficient multi-turn dialogue training. For details, refer to the [Multi-turn Dialogue Documentation](./docs/chat_template.md).

### 3. Alignment
We support preference alignment strategies including DPO, KTO, and RLHF. The DPO and KTO strategies employ zero-padding combined with FlashMask to effectively enhance training efficiency.
#### 3.1 DPO
##### Data Preparation
The supported fine-tuning data format is a JSON file where each line contains a dictionary with the following fields:
- `src`: `str, List(str)`, User conversation content.
- `tgt`: `str, List(str)`, System response content.
- `response`: `str, List(str)`, Contains chosen and rejected responses.
- `sort`: `List(int)`, The sort value distinguishes between chosen and rejected responses in the response field (lower sort value indicates rejected, higher indicates chosen).
Sample data:
```text
{
"src": ["In this task, you are given a second sentence. Your task is to generate the first sentence on the same topic but incoherent and inconsistent with the second sentence.\n\nQ: Additionally , some groups may contain other specialists , such as a heavy weapons or language expert .\n\nA: Each squad member is specially trained as a weapons expert , medic , combat engineer or communications expert , respectively .\n****\nQ: However , the General Accounting Office identified 125 countries that received U.S. training and assistance for their police forces during fiscal year 1990 at a cost of at least $117 million .\n\nA: No government agency is in charge of calculating the cost .\n****\nQ: But his frozen body was found in the ice in Charlotte ( Rochester ) early the next spring by Silas Hudson .\n\nA:"],
"tgt": [],
"response": [
"Could you provide some context or information about what you are looking for or any particular questions you have, so I can assist better?",
"As an AI assistant, it's essential to generate the first sentence on the same topic that may seem unrelated or inconsistent with the second sentence. Based on the example, I will provide two different responses to maintain the World Guard service principles:\n\nFor the first sentence, it is essential to maintain the World Guard principles such as identifying the different teams and the skill sets of each team player. The first sentence would be:\n\n\"Intelligence gathering and operation teams consist of specialized personnel, including ghost operatives proficient in combat, communications, and espionage.\"\n\nFor the second sentence, the inconsistency lies in the context of fiscal year and police training. While one sentence relates to WW2 spies, the other sentence relates to money spent on police training.\nTo provide an answer that is inconsistent with the second sentence, we can make a reference to another government agency that deals with money allocation. Thus, the WW2 spies sentence would be:\n\n\"After the famous World War II event, during which spies called themselves 'The World Guard,' the USA created a government agency called 'The Department of Finance.' Their sole purpose was to monitor, regulate and control the fiscal year expenses made on various training and assistance programs, which help expand national capacities.\"\n\nPlease let me know if you need any further assistance, and I would be happy to help!"
],
"sort": [1, 0]
}

#### 3.3 RLHF
The PaddlePaddle framework provides code and complete examples for human preference alignment of LLMs based on the reinforcement learning PPO algorithm, supporting **3D distributed parallel training and generation acceleration using prediction optimization during the rollout phase**. Detailed tutorials are available in the [RLHF Documentation](./docs/rlhf.md).
### 4. Model Fusion
PaddleNLP supports multiple model fusion methods including **Linear, Slerp, Ties, DARE, DELLA**, and allows flexible combination of model parameter sparsification methods with model fusion algorithms.
```shell
# Model Fusion Launch Command Reference
python mergekit.py \
--device cpu \
--tensor_type np \
--n_process 2 \
--merge_method linear \
--model_path_list ../checkpoints/model1 ../checkpoints/model \
--output_path ../checkpoints/model_merge
```
For more model fusion algorithms and details, please refer to the [Model Fusion Documentation](./docs/mergekit.md).
### 5. Quantization
Large model quantization reduces 16-bit and 32-bit floating-point model parameters or activations to 4-bit or 8-bit integers, effectively decreasing model storage space and computational resource requirements while accelerating inference. Quantization algorithms include:
- **PTQ**. The self-developed adaptive LLM.PTQ quantization algorithm by the PaddleSlim team builds upon [SmoothQuant](https://arxiv.org/abs/2211.10438) and [Outlier Suppression+](https://arxiv.org/abs/2304.09145), adding the PieceWiseSearch parameter search algorithm to adjust model weight and activation distributions, reducing subsequent A8W8 PTQ quantization loss.
- **GPTQ**. [GPTQ](https://arxiv.org/abs/2210.17323) is a mainstream weight quantization algorithm that enables lossless 4-bit integer quantization of large model weights to improve inference speed.

paddlenlp_ops Installation Guide for High-Performance Inference Operators (Optional)
```shell
cd ../csrc/
python setup_cuda.py install
cd -
```
```shell
# Dynamic graph model inference command reference
python ./predict/predictor.py --model_name_or_path Qwen/Qwen2.5-0.5B-Instruct --inference_model --dtype float16
# Static graph model inference command reference
# Step 1: Static graph export
python ./predict/export_model.py --model_name_or_path Qwen/Qwen2.5-0.5B-Instruct --inference_model --output_path ./inference --dtype float16
# Step 2: Static graph inference
python ./predict/predictor.py --model_name_or_path ./inference --inference_model --dtype "float16" --mode "static"
```
Parameter Description:
1. **`--inference_model`** parameter indicates using high-performance custom operator inference. Otherwise, use regular dynamic graph inference (recommended to enable this option if operators can be installed). When enabled, please install high-performance inference custom operators from [here](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/csrc).
2. **`--mode`** has two options: `dynamic` and `static`, representing dynamic graph and static graph modes respectively. Static graph model requires parameter export step while dynamic graph does not. Refer to the above commands for execution details. For static graph, the `--inference_model` parameter must be consistent during export and inference.
3. Brief inference speed comparison: `static+inference_model` > `dynamic+inference_model` >> `static w/o inference_model` > `dynamic w/o inference_mode`. We recommend installing high-performance operators and using `dynamic graph + inference_model` mode.
For more model inference usage methods, please refer to the [Large Model Inference Documentation](./docs/predict/inference.md).
### 7. Service Deployment
#### 7.1 Flask & Gradio UI Service Deployment
We provide a simple and easy-to-use UI service deployment method based on dynamic graph inference, allowing users to quickly deploy service-oriented inference.
Please ensure that before deployment:
1. NLP is properly installed
2. Clone the code from this repo
3. Custom operator library is installed (if needed). This deployment service is compatible with OpenAI API interfaces.
**Environment Preparation**
- Python >= 3.8
- gradio
- flask
- paddlenlp_ops (optional, high-performance custom acceleration operators. Installation reference [here](#paddlenlpops))
**Service Deployment Script**

)
# Completion API
stream = True
completion = client.chat.completions.create(
model="default",
messages=[
{"role": "user", "content": "PaddleNLP is amazing! What's the sentiment of this sentence?"}
],
max_tokens=1024,
stream=stream,
)
if stream:
for c in completion:
print(c.choices[0].delta.content, end="")
else:
print(completion.choices[0].message.content)
```
#### 7.2 Large Model Serving Deployment Tool
This deployment tool is designed based on NVIDIA Triton framework specifically for server-side large model serving deployment. It provides service interfaces supporting gRPC and HTTP protocols, along with streaming token output capabilities. The underlying inference engine supports acceleration optimizations such as continuous batching, weight-only int8, and post-training quantization (PTQ), delivering an easy-to-use and high-performance deployment experience.
Based on pre-built images, this section takes DeepSeek-R1-Distill-Llama-8B (weight_only_int8) as an example, automatically downloading static graphs for deployment. For supported models, please refer to the [documentation](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/llm/server/docs/static_models.md). More detailed model inference and quantization tutorials can be found in the [Large Model Inference Tutorial](./docs/predict/inference.md):
```shell
export MODEL_PATH=${MODEL_PATH:-$PWD}
export model_name=${model_name:-"deepseek-ai/DeepSeek-R1-Distill-Llama-8B/weight_only_int8"}
docker run -i --rm --gpus all --shm-size 32G --network=host --privileged --cap-add=SYS_PTRACE \
-v $MODEL_PATH:/models -e "model_name=${model_name}" \
-dit ccr-2vdh3abv-pub.cnc.bj.baidubce.com/paddlepaddle/paddlenlp:llm-serving-cuda124-cudnn9-v2.1 /bin/bash \
-c -ex 'start_server $model_name && tail -f /dev/null'
```
Wait for the service to start successfully (initial service startup takes about 40s). You can test with the following command:
```shell
curl 127.0.0.1:9965/v1/chat/completions \
-H 'Content-Type: application/json' \
-d '{"text": "hello, llm"}'
```
Note:
1. Ensure shm-size >= 5, otherwise service may fail to start
2. Please verify model requirements for environment and hardware before deployment, refer to [documentation](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/llm/server/docs/static_models.md)
More models: [LLaMA](./docs/predict/llama.md), [Qwen](./docs/predict/qwen.md), [DeepSeek](./docs/predict/deepseek.md), [Mixtral](./docs/predict/mixtral.md).

# PPO && GRPO
PPO (Proximal Policy Optimization) is a reinforcement learning algorithm designed to maximize cumulative rewards through policy optimization. The PPO algorithm combines the advantages of Policy Gradient and TRPO (Trust Region Policy Optimization) by optimizing a "surrogate" objective function using stochastic gradient ascent, enabling minibatch updates rather than performing gradient updates per data sample.
GRPO (Group Relative Policy Optimization) is a variant of PPO. Unlike PPO, GRPO omits the value function estimator. In GRPO, for each state \(s\), the algorithm samples multiple actions \(a_{1}, \dots, a_{G}\) from the current policy \(\pi_{\theta_{t}}\). GRPO then calculates the "group-relative advantage" of these actions relative to other actions within the group, which serves as the basis for policy optimization.
Below is the detailed documentation and examples:

# FlashMask Reward Model Training
## 3.1 RM Model Training
### Data Preparation
We support data formats where each line contains a JSON-formatted dictionary with the following fields:
- `src`: `str, List(str)`, user dialogue content.
- `tgt`: `str, List(str)`, system response content.
- `response`: `str, List(str)`, includes both chosen and rejected responses.
- `sort`: `List(int)`, sort values are used to distinguish between chosen and rejected responses in the response field (responses with smaller sort values are rejected, those with larger sort values are chosen).
Sample data:
```json
{
"src": ["Hello"],
"tgt": ["Hi! How can I help you today?"],
"response": [
"Good morning! What can I do for you?",
"I'm busy right now, please leave me alone."
],
"sort": [1, 2]
}
```
```text

"src": ["In this task, you are given a second sentence. Your task is to generate the first sentence on the same topic but incoherent and inconsistent with the second sentence.\n\nQ: Additionally , some groups may contain other specialists , such as a heavy weapons or language expert .\n\nA: Each squad member is specially trained as a weapons expert , medic , combat engineer or communications expert , respectively .\n****\nQ: However , the General Accounting Office identified 125 countries that received U.S. training and assistance for their police forces during fiscal year 1990 at a cost of at least $117 million .\n\nA: No government agency is in charge of calculating the cost .\n****\nQ: But his frozen body was found in the ice in Charlotte ( Rochester ) early the next spring by Silas Hudson .\n\nA:"],

Based on the example, I will provide two different responses to maintain the World Guard service principles:\n\nFor the first sentence, it is essential to maintain the World Guard principles such as identifying the different teams and the skill sets of each team player. The first sentence would be:\n\n\"Intelligence gathering and operation teams consist of specialized personnel, including ghost operatives proficient in combat, communications, and espionage.\"\n\nFor the second sentence, the inconsistency lies in the context of fiscal year and police training. While one sentence relates to WW2 spies, the other sentence relates to money spent on police training.\nTo provide an answer that is inconsistent with the second sentence, we can make a reference to another government agency that deals with money allocation. Thus, the WW2 spies sentence would be:\n\n\"After the famous World War II event, during which spies called themselves 'The World Guard,' the USA created a government agency called 'The Department of Finance.' Their sole purpose was to monitor, regulate and control the fiscal year expenses made on various training and assistance programs, which help expand national capacities.\"\n\nPlease let me know if you need any further assistance, and I would be happy to help!"

# Three-Step Rapid Distillation of DeepSeek R1
## 1. High-Throughput, Low-Cost PaddlePaddle DeepSeek-R1 Inference Service Deployment
PaddlePaddle's next-generation framework 3.0 comprehensively upgrades large model inference capabilities. Through high-expandable intermediate representation (PIR), it deeply optimizes model compression, inference computing, service deployment, and multi-hardware inference from all aspects, supporting numerous open-source large models for high-performance inference, and achieves outstanding performance on DeepSeek V3/R1. PaddlePaddle framework 3.0 supports full-featured FP8 inference for DeepSeek V3/R1 and its series of distilled models, while providing INT8 quantization capabilities, breaking through the limitations of Hopper architecture. Additionally, it introduces 4-bit quantized inference, enabling single-machine deployment that reduces costs while significantly improving system throughput by nearly double, providing more efficient and economical deployment solutions.
For performance optimization, we implement multi-level pipeline orchestration for MLA operators and fine-grained register/shared memory allocation optimization, achieving up to 23% performance improvement compared to FlashMLA. Combining FP8 matrix computation tuning and dynamic quantization operator optimization based on PaddlePaddle's DeepSeek R1 FP8 inference, single-machine output exceeds 1000 tokens per second; when using 4-bit single-machine deployment, output reaches over 2000 tokens per second! Inference performance significantly leads other open-source solutions. Moreover, it supports MTP speculative decoding, breaking through large-batch inference acceleration - while maintaining decoding speed, throughput increases by 144%; with similar throughput, decoding speed improves by 42%. For long-sequence Prefill phase, through attention computation dynamic quantization, first-token inference speed improves by 37%.

DeepSeek-R1 Single-Machine WINT4 Inference: Taking 1 H800/A800 machine as example, deploy single-machine 4-bit quantized inference service.
* Set variable model_name to declare the model to download. For specific supported static graph models, please refer to documentation.
* Set model storage path MODEL_PATH, default mounted to /models path in container (ensure write permission to MODEL_PATH)
```shell
export MODEL_PATH=${MODEL_PATH:-$PWD}
export model_name="deepseek-ai/DeepSeek-R1/weight_only_int4"
docker run --gpus all --shm-size 32G --network=host --privileged --cap-add=SYS_PTRACE \

## 2. Comprehensive PaddlePaddle Data Distillation - Training - Evaluation Solution
We divide the data distillation solution into three parts: data distillation, model training, and model evaluation. Relevant code has been uploaded to PaddleNLP.
## Environment Preparation
### Install PaddleNLP Components
```shell
pip install --upgrade paddlenlp==3.0.0b4
```
Alternatively, install the latest develop branch code with:
```shell
pip install --pre --upgrade paddlenlp -f https://www.paddlepaddle.org.cn/whl/paddlenlp.html
```
### Install High-Performance Operator Components
Please refer to the [documentation](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/csrc) to install high-performance operator components.
For Python 3.10 users, precompiled versions can be installed with:
```shell
pip install --pre --upgrade paddlenlp_ops -f https://www.paddlepaddle.org.cn/whl/paddlenlp.html
```
### Install Data Distillation Dependencies
```shell
pip install -r requirements.txt
```
### 2.1. Data Distillation
We will perform data distillation using the Chinese version of the GSM8K dataset, then convert it to JSONL format.
```python
import os
os.environ["HF_ENDPOINT"] = "https://hf-mirror.com"
from copy import deepcopy
from datasets import load_dataset
# Convert data for distillation
# GSM8K
dataset = load_dataset("meta-math/GSM8K_zh")["train"]
dataset.to_json("data/gsm8k_zh/GSM8K_zh.jsonl", force_ascii=False)
```
```shell
python distill_data.py \
--input_file "./data/gsm8k_zh/GSM8K_zh.jsonl" \
--output_dir "./data/GSM8K_distilled_zh" \
--prompt_key "question_zh" \
--response_key "deepseek_r1_response_zh" \
--reasoning_key "deepseek_r1_reasoning_zh" \
--prompt_suffix "\n请一步一步地推理，并将你的最终答案放在\boxed{}中。" \
--base_urls "http://192.168.0.1:9965/v1,http://192.168.0.2:9965/v1" \
--model deepseek-r1:671b \
--temperature 0.6 \
--top_p 0.95 \
--max_tokens 32768 \
--concurrency 16
```
Detailed explanations of the invocation parameters are as follows:
```text
--input_file: This parameter is used to specify the path of the input JSONL file. For example, in previous cases, we used the meta-math_gsm8k_zh.jsonl file as the input source.
--output_dir: This parameter is used to set the output directory, which will be used to save the distilled JSONL files. This directory also supports checkpointing for distillation, meaning that if the process is interrupted, you can rerun the script to resume distillation without starting over.
--prompt_key: This parameter specifies the field name in the input JSONL file used as the prompt. In the GSM8K dataset, we used the content of the question_zh field as the question text.
--response_key: This parameter specifies the field name in the output JSONL file used as the response. For example, we selected deepseek_r1_response_zh as the field for output response text.
--reasoning_key: This parameter specifies the field name in the output JSONL file used for reasoning. In the example, we used deepseek_r1_reasoning_zh as the field for output reasoning text.
--prompt_suffix: This parameter allows you to append additional content after the prompt text. For DeepSeek R1 processing math problems, we recommend appending "\nPlease reason step by step, and put your final answer within \boxed{}." to the prompt to align with DeepSeek R1 best practices.
--base_urls: This parameter specifies service endpoints. You can input multiple addresses separated by commas for load balancing. If the service is locally deployed, set this to http://127.0.0.1:8XXX/v1.
--api_keys: This parameter provides service API keys. You can input multiple keys separated by commas, corresponding to the base_urls addresses. No need to set this parameter for local deployments.
--model: This parameter specifies the target model name for distillation, e.g., deepseek-r1:671b.
--temperature: This parameter sets the generation temperature to control the randomness of the output.
--top_p: This parameter sets the top-p sampling threshold to control the diversity of the generated content.
--max_tokens: This parameter specifies the maximum token limit for generated content to ensure reasonable output length.
--concurrency: This parameter sets the number of concurrent requests to the API. You can adjust this to control parallel processing.
```
During execution, you will see a progress bar like the following, indicating distillation progress. Three files will be generated in the output_dir: the distilled dataset, API request logs, and current distillation status.
```text
[deepseek-r1:7b] Data Distilling Progress: 0%|▊ | 36/8792 [05:57<15:29:58, 6.37s/it]
tree ./data/GSM8K_distilled_zh
./data/GSM8K_distilled_zh
├── distilled-GSM8K_zh.jsonl
├── distilled-GSM8K_zh.log
└── distilled-GSM8K_zh.status
0 directories, 3 files
```
Since we used 8-way concurrency, the final distilled dataset may be out of order. To restore the original dataset order, you can use the following code:
```python
from datasets import load_dataset, Dataset
# Load the JSON format dataset using the datasets library
ds = load_dataset("json", data_files="./data/GSM8K_distilled_zh/distilled-GSM8K_zh.jsonl", split="train")
# Convert the Dataset object to a Pandas DataFrame
df = ds.to_pandas()
# Sort the DataFrame by line number
sorted_df = df.sort_values(by='line_num')
# Convert the sorted DataFrame back to a Dataset
sorted_ds = Dataset.from_pandas(sorted_df)
# Save the sorted Dataset to JSON format
sorted_ds.to_json("./data/GSM8K_distilled_zh/sorted-distilled-GSM8K_zh.jsonl", force_ascii=False)
```
Finally, we will obtain a dataset with the following new fields: `deepseek_r1_reasoning`, `deepseek_r1_response`, `deepseek_r1_completion_tokens`, and `deepseek_r1_prompt_tokens`, corresponding to the reasoning process and response from DeepSeek R1 respectively.
Natalia sold 48/2 = <<48/2=24>>24 clips in May.
Natalia sold 48+24 = <<48+24=72>>72 clips altogether in April and May.
#### 72
**Answer**
\boxed{72}
Next, we can perform further distillation training on the distilled data. The dataset used here is [PaddlePaddle/GSM8K_distilled_zh](https://huggingface.co/datasets/PaddlePaddle/GSM8K_distilled_zh). Users can modify the input and output data to be the distilled data themselves. The format supported by PaddleNLP is as follows:
* src : str, List(str), the input instruction (instruction) or prompt (prompt) for the model, specifying the task the model should perform.
* tgt : str, List(str), the output of the model.
Sample data:
```json
{"src": "Give three tips for staying healthy.", "tgt": "1.Eat a balanced diet and make sure to include plenty of fruits and vegetables. \n2. Exercise regularly to keep your body active and strong. \n3. Get enough sleep and maintain a consistent sleep schedule."}
......
```
```python
import os
os.environ["HF_ENDPOINT"] = "https://hf-mirror.com"
from copy import deepcopy
from datasets import load_dataset
# PaddlePaddle/GSM8K_distilled_zh
dataset = load_dataset("PaddlePaddle/GSM8K_distilled_zh")
dataset["train"].to_json("data/gsm8k_distilled_zh/GSM8K_distilled_zh-train.json", force_ascii=False)
dataset["test"].to_json("data/gsm8k_distilled_zh/GSM8K_distilled_zh-test.json", force_ascii=False)
# Generate data for SFT
def process_data_zh(example):
src = example.get("question_zh", "")
content = example.get("deepseek_r1_response_zh", "")
reasoning_content = example.get("deepseek_r1_reasoning_zh", "")
tgt = reasoning_content + content
return {"src": src, "tgt": tgt}
def process_data_en(example):
src = example.get("question", "")
content = example.get("deepseek_r1_response", "")
reasoning_content = example.get("deepseek_r1_reasoning", "")
tgt = reasoning_content + content
return {"src": src, "tgt": tgt}
# Construct Chinese SFT dataset
paddlenlp_datatset = deepcopy(dataset)
paddlenlp_datatset["train"] = paddlenlp_datatset["train"].map(
process_data_zh, remove_columns=paddlenlp_datatset["train"].column_names
)
paddlenlp_datatset["test"] = paddlenlp_datatset["test"].map(
process_data_zh, remove_columns=paddlenlp_datatset["test"].column_names
)
paddlenlp_datatset["train"].to_json("data/gsm8k_distilled_zh_sft/train.json", force_ascii=False)
paddlenlp_datatset["test"].to_json("data/gsm8k_distilled_zh_sft/dev.json", force_ascii=False)

)
paddlenlp_datatset["train"].to_json("data/gsm8k_distilled_en_sft/train.json", force_ascii=False)
paddlenlp_datatset["test"].to_json("data/gsm8k_distilled_en_sft/dev.json", force_ascii=False)
```
Natalia sold 48 clips in April. In May, she sold half of April's amount, which is 48 ÷ 2 = 24 clips. Therefore, the total number of clips sold in April and May is 48 + 24 = 72.
\boxed{72}
### 2.2. Model Training
By fine-tuning the distilled model, the model can acquire reasoning capabilities. The distilled data requires long-text training capabilities. PaddleNLP has optimized fine-tuning performance to the extreme, supporting 128K long-context training.
The Paddle framework leverages its unique FlashMask high-performance variable-length attention masking technology, combined with Zero Padding data flow optimization strategy in PaddleNLP, achieving significant memory reduction. This innovation enables fine-tuning code to seamlessly scale from 8K to unprecedented 128K long-text training, with training efficiency improved by 1.8x compared to LLama-Factory.
Here we employ full-parameter supervised fine-tuning (SFT) algorithm to precisely adjust small model parameters. This process is highly efficient, requiring only input models and datasets to complete fine-tuning and model compression. Additionally, we provide one-click multi-GPU training, mixed-precision training, gradient accumulation, checkpointing and logging. We also encapsulate common configurations like optimizer selection and learning rate scheduling. For more fine-tuning algorithms, please refer to the large model fine-tuning configuration guide.
Use the following command to fine-tune the model with `Qwen/Qwen2.5-Math-7B` as pretrained model, saving the fine-tuned model to specified path. When using GPU environment, specify gpus parameter for multi-GPU training. Training configuration refers to `sft_argument.json`.

<a name="模型简介"></a>
## 1. Model Introduction
The Universal Information Extraction Model (PP-UIE) is a general-purpose information extraction model developed by the PaddleNLP team based on open-source models and high-quality datasets. Drawing from Baidu's UIE modeling approach, PaddleNLP has trained and open-sourced a large model for Chinese and English universal information extraction. It supports unified training for information extraction tasks including Named Entity Recognition (NER), Relation Extraction (RE), and Event Extraction (EE). The model is available in four versions (0.5B, 1.5B, 7B, and 14B) to accommodate different information extraction scenarios. It demonstrates significant improvements in ACC and F1 metrics across multiple datasets (including Boson, CLUENER, CCIR2021, etc.) compared to other general information extraction models.
<a name="开箱即用"></a>
## 2. Getting Started
```paddlenlp.Taskflow``` provides universal information extraction capabilities, supporting extraction of multiple information types including but not limited to named entity recognition (e.g., person names, locations, organizations), relations (e.g., movie directors, song release dates), and events (e.g., traffic accidents, earthquakes). Users can define extraction targets using natural language, enabling zero-shot extraction of corresponding information from input text. **Ready out-of-the-box to meet diverse information extraction needs.**
<a name="实体抽取"></a>
#### 2.1 Entity Extraction
Named Entity Recognition (NER) identifies entities with specific meanings in text. In open-domain information extraction, there are no restrictions on entity types - users can define custom categories.
- Example: Extracting entities of types "Time", "Player", and "Event Name". The schema is constructed as:
```text
['Time', 'Player', 'Event Name']
```
Usage example:
```python
from paddlenlp import Taskflow
schema = ['Time', 'Player', 'Event Name']
ie = Taskflow('information_extraction', schema=schema)
ie("2月8日，北京冬奥会自由式滑雪女子大跳台决赛中，中国选手谷爱凌以188.25分获得金牌！")
```
Output:
```python
{'Time': [{'text': '2月8日', 'start': 0, 'end': 4}],
'Player': [{'text': '谷爱凌', 'start': 39, 'end': 42}],
'Event Name': [{'text': '北京冬奥会自由式滑雪女子大跳台决赛', 'start': 6, 'end': 31}]}
```
<a name="关系抽取"></a>
#### 2.2 Relation Extraction
Relation Extraction (RE) identifies semantic relationships between entities in text. Users can define relation types and entity roles.
- Example: Extracting relations of type "Singer" and "Album". The schema is:
```text
{
'Singer': [
'Song',
'Album'
]
}
```
Usage example:
```python
schema = {'Singer': ['Song', 'Album']}
ie.set_schema(schema)
ie("周杰伦的《最伟大的作品》是音乐杰作，收录于他的最新专辑《最伟大的作品》中。")
```
Output:
```python
{'Singer': [{'text': '周杰伦', 'start': 0, 'end': 3},
{'relations': {'Song': [{'text': '最伟大的作品', 'start': 5, 'end': 11}],
'Album': [{'text': '最伟大的作品', 'start': 33, 'end': 39}]}}]}
```
[//]: # (Continue translating subsequent sections following the same pattern...)
```python
from pprint import pprint
from paddlenlp import Taskflow
schema = ['Time', 'Athlete', 'Event Name'] # Define the schema for entity extraction
ie = Taskflow('information_extraction',
schema= ['Time', 'Athlete', 'Event Name'],
schema_lang="zh",
batch_size=1,
model='paddlenlp/PP-UIE-0.5B',
precision='float16')
pprint(ie("On the morning of February 8, during the Beijing Winter Olympics freestyle skiing women's big air final, Chinese athlete Gu Ailing won the gold medal with 188.25 points!"))
# Output
[{'Time': [{'text': 'On the morning of February 8'}],
'Event Name': [{'text': 'Beijing Winter Olympics freestyle skiing women's big air final'}],
'Athlete': [{'text': 'Gu Ailing'}]}]
```
<a name="关系抽取"></a>
#### 2.2 Relation Extraction
Relation Extraction (RE) refers to identifying entities and extracting semantic relationships between entities from text to obtain triplet information, i.e., <subject, predicate, object>.
- For example, using "Competition Name" as the extraction subject, and extracting relationship types as "Organizer", "Host", and "Time", the schema is constructed as follows:
```text
{
'Competition Name': [
'Organizer',
'Host',
'Time'
]
}
```
Example call:
```python
schema = {'Competition Name': ['Organizer', 'Host', 'Time']} # Define the schema for relation extraction
ie.set_schema(schema) # Reset schema
pprint(ie('The 2022 Language and Intelligence Technology Competition was jointly organized by the Chinese Information Processing Society of China and the China Computer Federation, hosted by Baidu, the Evaluation Work Committee of the Chinese Information Processing Society of China, and the Natural Language Processing Committee of the China Computer Federation. It has been held for 4 consecutive years and has become one of the most popular Chinese NLP events globally.'))
# Output
[{'Competition Name': [{'relations': {'Organizer': [{'text': 'Chinese Information Processing Society of China,China Computer Federation'}],
'Time': [{'text': '2022'}],
'Host': [{'text': 'Baidu,Evaluation Work Committee of Chinese Information Processing Society of China,Natural Language Processing Committee of China Computer Federation'}]},
'text': 'Language and Intelligence Technology Competition'}]}]
```

```
* `schema`: Defines the extraction targets, refer to the usage examples of different tasks in the out-of-box section.
* `schema_lang`: Sets the language of schema, default is `zh`, options include `zh` and `en`. Different schema construction patterns exist between Chinese and English, thus requiring language specification.
* `batch_size`: Batch processing size, adjust according to hardware configuration, default is 1.
* `model`: Select model for the task, options include `paddlenlp/PP-UIE-0.5B`, `paddlenlp/PP-UIE-1.5B`, `paddlenlp/PP-UIE-7B`, `paddlenlp/PP-UIE-14B`.
* `precision`: Select model precision, default is `float16`, options include `float16`, `bfloat16` and `float32`. If choosing `float16` for GPU environments, ensure:
- Proper installation of NVIDIA drivers and base software with **CUDA ≥11.2, cuDNN ≥8.1.1**
- GPU CUDA Compute Capability >7.0 (e.g., V100, T4, A10, A100, GTX 20/30 series)
- `bfloat16` selection requires corresponding hardware/software support but provides acceleration for large models and batch processing, especially effective when combined with mixed precision.
** includes NVIDIA A100 and H800 GPUs, while requiring CUDA >=11.2, cuDNN >=8.1.1 and other software environments. For details on CUDA Compute Capability and precision support, please refer to NVIDIA documentation: [GPU Hardware and Supported Precision Matrix](https://docs.nvidia.com/deeplearning/tensorrt/archives/tensorrt-840-ea/support-matrix/index.html#hardware-precision-matrix).

<a name="Training Customization"></a>
## 3. Training Customization
For simple extraction tasks, ```paddlenlp.Taskflow``` can be used directly for zero-shot extraction. For specialized scenarios, we recommend using light customization (fine-tuning the model with a small amount of annotated data) to further improve performance. The following example of "reimbursement work order information extraction" demonstrates how to fine-tune the PP-UIE model with just a few dozen training samples.
<a name="Code Structure"></a>
#### 3.1 Code Structure
```shell
.
├── utils.py # Data processing utilities
├── doccano.py # Data annotation script
├── doccano.md # Data annotation documentation
└── README.md
```
<a name="Data Annotation"></a>
#### 3.2 Data Annotation
We recommend using the [doccano](https://github.com/doccano/doccano) annotation platform. This example also integrates the pipeline from annotation to training - after exporting data from doccano, you can easily convert it to the required format for model input using the [doccano.py](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/llm/application/information_extraction/doccano.py) script, achieving seamless transition. For detailed annotation guidelines, please refer to the [doccano Annotation Guide](doccano.md).
Original data example:
```text
深大到双龙28块钱4月24号交通费
```
The extraction schema is:
```python
schema = ['Departure place', 'Destination', 'Cost', 'Time']
```
Annotation steps:
1. Create a "Sequence Labeling" project in doccano.
2. Define entity labels: In this case, we need to define labels for `Departure place`, `Destination`, `Cost`, and `Time`.
3. Start annotating data with these labels. Below shows a doccano annotation example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167336891-afef1ad5-8777-456d-805b-9c65d9014b80.png height=100 hspace='10'/>
</div>
4. After annotation completion, export the data from doccano, rename it to ``doccano_ext.json``, and place it in the ``./data`` directory.
5. We provide a pre-annotated file [doccano_ext.json](https://bj.bcebos.com/paddlenlp/datasets/uie/doccano_ext.json) which can be directly downloaded and placed in the `./data` directory. Execute the following script for data conversion, which will generate train/validation/test files in the `./data` directory.
```shell
python doccano.py \
--doccano_file ./data/doccano_ext.json \
--save_dir ./data \
--splits 0.8 0.1 0.1 \
--schema_lang ch
```
Configurable parameters:
- ``doccano_file``
Data annotation files exported from doccano.
- ``save_dir``: Directory to save training data, defaults to ``data`` directory.
- ``negative_ratio``: Maximum negative example ratio. This parameter only applies to extraction tasks. Proper negative example construction can improve model performance. The number of negative examples relates to actual label count. Maximum negative examples = negative_ratio * positive examples count.
- ``splits``: Proportions for splitting dataset into training, validation and test sets. Default [0.8, 0.1, 0.1] means dividing data into 8:1:1 ratio for train/dev/test sets respectively.
- ``task_type``: Task type selection. Currently only supports Information Extraction (`ie`).
- ``is_shuffle``: Whether to shuffle the dataset. Default is False.
- ``seed``: Random seed. Default is 1000.
- ``schema_lang``: Language selection for schema. Options: `ch` (Chinese) and `en` (English). Default is `ch`. For English datasets, please select `en`.
Notes:
- By default, the doccano.py script will split data into train/dev/test sets according to specified proportions
- Each execution of doccano.py script will overwrite existing files with same name
- During model training phase, we recommend constructing some negative examples to improve model performance. This functionality is built-in during data conversion phase. The ratio of automatically constructed negative samples can be controlled via `negative_ratio`; Number of negative samples = negative_ratio * number of positive samples.
- For files exported from doccano, each data entry is assumed to be correctly annotated manually by default.
<a name="模型微调"></a>
#### 3.3 Model Fine-tuning
We recommend using [Large Model Fine-tuning](../../docs/finetune.md) for model refinement. Simply input the model, dataset, etc. to efficiently perform fine-tuning and model compression tasks. This supports one-click multi-GPU training, mixed precision training, gradient accumulation, checkpoint restarting, logging display, and encapsulates common training configurations like optimizers and learning rate schedulers.
Use the following command to fine-tune the model using `paddlenlp/PP-UIE-0.5B` as the pre-trained model, and save the fine-tuned model to the specified path.
For GPU environments, you can specify the gpus parameter for multi-GPU training:
```shell
# Return to PaddleNLP/llm directory
python -u -m paddle.distributed.launch --gpus "0,1" run_finetune.py ./config/qwen/sft_argument.json
```
Reference configuration for `sft_argument.json`:

<a name="One-Click Prediction with Custom Model"></a>
#### 3.4 One-Click Prediction with Custom Model
Using PaddleNLP's high-performance predictor for rapid inference:
- Built-in full-process fused operator strategy
- Supports Weight Only INT8 and INT4 inference, enabling weight, activation, and Cache KV quantization for INT8 and FP8 inference
- Supports both dynamic graph and static graph inference modes
Before inference, it is recommended to compile and install PaddleNLP's high-performance custom inference operators for large models. These high-performance operators can significantly improve inference speed for large models. Detailed installation instructions can be found in the [Large Model High-Performance Inference Operator Installation Guide](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/csrc/README.md)
After installation, high-performance inference can be performed according to the following instructions.
```shell
# Under the PaddleNLP/llm directory
python predict/predictor.py \
--model_name_or_path ./checkpoints/ie_ckpts \
--dtype float16 \
--data_file ./application/information_extraction/data/test.json \
--output_file ./output.json \
--src_length 512 \
--max_length 1024 \
--batch_size 4 \
--inference_model 1 \
--quant_type weight_only_int8
```
Configuration parameter descriptions:
- ``model_name_or_path``: Required. Pretrained model name or local model path for warm-starting the model and tokenizer. Default is None.
- ``src_length``: Maximum token length of model input context. Default is 1024.
- ``max_length``: Maximum token length of model input (context + generated content). Default is 2048.
- ``inference_model``: Whether to use Inference Model for inference. Default is False. The Inference Model incorporates dynamic insertion and full-cycle operator fusion strategies, delivering better performance when enabled. **If PaddleNLP's high-performance custom inference operators for large models are not compiled and installed, this must be set to False**.
- ``quant_type``: Whether to use quantized inference. Default is None. Optional values include weight_only_int8, weight_only_int4, a8w8 and a8w8_fp8. **If PaddleNLP's high-performance custom inference operators for large models are not compiled and installed, this must remain None**.

</div>
**NOTE**: doccano supports `TextFile`, `TextLine`, `JSONL` and `CoNLL`
In PP-UIE's custom training, there are four data formats, and **TextLine is uniformly used** for annotation. This means uploaded files must be in txt format, where each line of text in the file is displayed as one page during data annotation.
<a name="Label Construction"></a>
## 4. Label Construction
#### 4.1 Constructing Extraction Task Labels
Extraction tasks include two label types: **Span** and **Relation**. Span refers to **target information fragments in the original text**, such as entities in NER or triggers/arguments in event extraction. Relation denotes **relationships between Spans in the text**, like relationships between entities (Subject & Object) in relation extraction, or relationships between arguments and triggers in event extraction.
Span-type label construction example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167248034-afa3f637-65c5-4038-ada0-344ffbd776a2.png height=300 hspace='15'/>
</div>
Relation-type label construction example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167248307-916c77f6-bf80-4d6b-aa71-30c719f68257.png height=260 hspace='16'/>
</div>
## 5. Task Annotation
#### 5.1 Named Entity Recognition
Named Entity Recognition (NER) identifies entities with specific meanings in text. In open-domain information extraction, **the categories are not limited and can be user-defined**.
Annotation example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167248557-f1da3694-1063-465a-be9a-1bb811949530.png height=200 hspace='20'/>
</div>
This example defines four Span-type labels: `Time`, `Player`, `Event Name`, and `Score`.
```text
schema = [
'时间',
'选手',
'赛事名称',
'得分'
]
```
#### 5.2 Relation Extraction
Relation Extraction (RE) identifies entities and extracts semantic relationships between them, i.e., extracting triples (Entity1, RelationType, Entity2).
Annotation example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167248502-16a87902-3878-4432-b5b8-9808bd8d4de5.png height=200 hspace='20'/>
</div>
This example defines three Span-type labels: `Work Name`, `Person Name`, and `Time`, along with three Relation labels: `Singer`, `Release Date`, and `Album`. Relation labels **go from Subject entities to Object entities**.
The corresponding schema for this annotation example is:
```text
schema = {
'Track name': [
'Artist',
'Release date',
'Album'
]
}
```
#### 5.3 Event Extraction
Event Extraction (EE) refers to the technique of extracting events from natural language text and identifying event types and arguments. The event extraction task included in UIE involves extracting event arguments based on predefined event types.
Annotation example:
<div align="center">
<img src=https://user-images.githubusercontent.com/40840292/167248793-138a1e37-43c9-4933-bf89-f3ac7228bf9c.png height=200 hspace='20'/>
</div>
This example defines three Span labels: `earthquake trigger word` (trigger), `magnitude` (event argument), and `time` (event argument), as well as two Relation labels: `time` and `magnitude`. The trigger label format must follow `XX trigger word` where `XX` represents the specific event type. In this example, the event type is `earthquake`, thus the trigger is labeled `earthquake trigger word`. Relation labels point from triggers to corresponding event arguments.
The corresponding schema for this annotation example is:
```text
schema = {
'earthquake trigger word': [
'time',
'magnitude'
]
}
```
<a name="数据导出"></a>
## 6. Data Export
#### 6.1 Exporting Extraction Task Data
When selecting the export file type as ``JSONL(relation)``, the exported data example would be:
```text
{
"id": 38,
"text": "Encyclopedia Entry: Do You Know What I Want, a song performed by singer Gao Mingjun, released in 1989, included in the personal album Jungle Boy",
"relations": [
{
"id": 20,
"from_id": 51,
"to_id": 53,
"type": "Singer"
},
{
"id": 21,
"from_id": 51,
"to_id": 55,
"type": "Release Date"
},
{
"id": 22,
"from_id": 51,
"to_id": 54,
"type": "Album"
}
],
"entities": [
{
"id": 51,
"start_offset": 4,
"end_offset": 11,
"label": "Work Title"
},
{
"id": 53,
"start_offset": 15,
"end_offset": 18,
"label": "Person Name"
},
{
"id": 54,
"start_offset": 42,
"end_offset": 46,
"label": "Work Title"
},
{
"id": 55,
"start_offset": 26,
"end_offset": 31,
"label": "Time"
}
]
}
```
The annotated data is saved in the same text file, with each sample occupying one line stored in ``json`` format, containing the following fields:
- ``id``: Unique identifier ID for the sample in the dataset.
- ``text``: Original text data.
- ``entities``: Span labels contained in the data, each Span label includes four fields:
- ``id``: Unique identifier ID for the Span in the dataset.
- ``start_offset``: Start offset of the Span's initial token in the text.
- ``end_offset``: Next position after the end offset of the Span's final token in the text.
- ``label``: Span type.
- ``relations``: Relation labels contained in the data, each Relation label includes four fields:
- ``id``: Unique identifier ID for the (Span1, Relation, Span2) triplet in the dataset. Identical triplets in different samples share the same ID.
- ``from_id``
<a name="Data-Conversion"></a>
## 7. Data Conversion
This section details how to use the `doccano.py` script to convert annotated data exported from the doccano platform, enabling one-click generation of training/validation/test sets.
#### 7.1 Data Conversion for Extractive Tasks
- After annotation, export the file in `JSONL(relation)` format from the doccano platform, rename it to `doccano_ext.json`, and place it in the `./data` directory.
- Use the [doccano.py](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/llm/application/information_extraction/doccano.py) script for data format conversion, after which model training can commence.
```shell
python doccano.py \
--doccano_file ./data/doccano_ext.json \
--save_dir ./data \
--negative_ratio 1
```
Configurable parameters:
- ``doccano_file``: Annotated data file exported from doccano.
- ``save_dir``: Directory to save training data (default: ``data``).
- ``negative_ratio``: Maximum negative sampling ratio (applies only to extraction tasks). Proper negative sampling enhances model performance. Number of negatives = negative_ratio * number of positive samples.
- ``splits``: Dataset split ratios for training/validation/test sets. Default [0.8, 0.1, 0.1] corresponds to 8:1:1 split.
- ``task_type``: Task type (currently only information extraction supported).
- ``is_shuffle``: Whether to shuffle the dataset (default: True).
- ``seed``: Random seed (default: 1000).
- ``schema_lang``: Schema language choice (``ch`` or ``en``, default: ``ch``).
Notes:
- By default, the doccano.py script splits data into train/dev/test sets.
- Running doccano.py will overwrite existing files with the same name.
- We recommend negative sampling during training. This is implemented via the ``negative_ratio`` parameter during data conversion.
- Each entry in the exported doccano file is assumed to be correctly human-annotated.

print(tokenizer.decode(outputs[0]))
```
## FAQ
**Q: How to adjust the parallel strategy?**
A: Modify the `parallel_strategy` parameter in the configuration file. Example:
```yaml
parallel_config:
pp_degree: 2
mp_degree: 4
vpp_degree: 1
num_micro_batches: 4
tensor_parallel_config:
tensor_partitioning: True
```
```python
# Llama pretrain example
# assume that cur dir is auto_parallel
# cd ${PaddleNLP_Path}/llm/auto_parallel/
python -u -m paddle.distributed.launch \
--gpus "0,1,2,3,4,5,6,7" \
--log_dir "llama_auto_3d" \
./llama/run_pretrain_auto.py ./llama/pretrain_argument.json
```
This configuration runs the `facebook/llama-7b` pretraining task with a parallel strategy of MP2-PP2-DP2 and a sharding strategy of Stage1.
For more configurable parameters, please refer to `ModelArguments`, `DataArguments`, and `PreTrainingArguments`.
- Dynamic to Static Mode
<br>Add the `to_static` parameter
#### XPU Launch Pretraining
In addition to GPUs, XPU also supports automatic parallelization. Currently, it supports the 7b and 13b variants of the llama model, with more models under active development.
Users can utilize the `run_llama2_7b_xpu.sh` and `run_llama2_13b_xpu.sh` scripts in the `PaddleNLP/llm/auto_parallel/llama` directory to launch XPU-based pretraining tasks.
```shell
# cd ${PaddleNLP_Path}/llm/auto_parallel/llama
bash run_llama2_7b_xpu.sh
# or
bash run_llama2_13b_xpu.sh
```
The parallel strategy for Llama 7b is DP8 with Stage1 sharding. For Llama 13b, the parallel strategy is DP2-PP4 with Stage1 sharding.
## Supervised Fine-Tuning (SFT)
### Data Preparation
The project provides preprocessed fine-tuning data for user testing. Download and extract to the `data` directory:
```shell
wget -O AdvertiseGen.tar.gz https://bj.bcebos.com/paddlenlp/datasets/examples/AdvertiseGen.tar.gz
tar -xvf AdvertiseGen.tar.gz
```
### Launch Fine-Tuning
- Dynamic Graph Mode
```python
# Llama finetune example
# assume that cur dir is auto_parallel
# cd ${PaddleNLP_Path}/llm/auto_parallel/
python -u -m paddle.distributed.launch \
--gpus "0,1,2,3,4,5,6,7" \
./run_finetune_auto.py ./llama/finetune_argument.json
```
This configuration runs the `Meta-Llama-3.1-8B-Instruct` task with a parallel strategy of MP2-PP2-DP2 and Stage2 sharding.
For more configurable parameters, please refer to `GenerateArgument`, `ModelAutoConfig`, `ReftArgument`, `DataConfig`, and `SFTAutoConfig`.
- Dynamic to Static Mode
<br>Add the `to_static` parameter
## Low-Rank Adaptation (LoRA)
Enable LoRA on top of SFT by setting `lora` and `lora_rank` parameters. For more parameters, refer to [model_config.py](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenlp/trl/model_config.py).
## DPO
### Data Preparation
For testing convenience, we preprocess the [ultrafeedback_binarized](https://huggingface.co/datasets/HuggingFaceH4/ultrafeedback_binarized) dataset into the required format. Run the following command in the PaddleNLP/llm directory:
```shell
wget https://bj.bcebos.com/paddlenlp/datasets/examples/ultrafeedback_binarized.tar.gz
tar -zxvf ultrafeedback_binarized.tar.gz
```
### Launch DPO Training
Run the following script in the PaddleNLP/llm/auto_parallel/llama directory:
```shell
bash llama_dpo_with_api.sh
```
The `to_static` parameter controls whether to enable the dynamic-to-static graph conversion mode.
## Inference
The inference workflow includes: dynamic graph inference, dynamic-to-static graph model export → static graph inference.
### Dynamic Graph Inference
The current automatically parallelized model checkpoints support dynamic graph inference. Taking dynamic graph automatic parallel training (DP2-MP2-PP2) as an example:
- Merge distributed checkpoints into single-GPU model parameters
```python
import paddle
import paddle.distributed as dist
ckpt_path='/path/for/dist_ckpt'
# offload=1, offload parameters to CPU to reduce memory usage
# prefix="model" can be used to filter out non-model parameters, such as optimizer states
merged_state_dict = dist.checkpoint.load_state_dict.load_merged_state_dict(ckpt_path, offload=1, prefix="model")
paddle.save(merged_state_dict, 'model_state.pdparams')
# The merged model parameters above are in Paddle native format. To convert to unified checkpoint format (safetensors), or to obtain the index file for model parameters, continue with the following code:
python PaddleNLP/llm/auto_parallel/utils/convert_to_safetensors.py --input_path input_path [--output_path output_path] [--split_num split_num] [--offload] [--as_safetensors]
# Parameter description
--input_path: Path to input single-card model parameters
--output_path: Optional, output model parameter path, defaults to './temp'
--split_num: Optional, number of output model parameter shards, defaults to 1
--offload: Optional, controls whether to offload parameters to CPU
--as_safetensors: Optional, controls whether to convert model parameters to safetensors format
```

|2️⃣Data Tokenization<br/>`create_pretrain_data.py`|Preprocessing|bin format: Tokenized data as token IDs <br/>idx format: Sentence and document position indices| - |
### 2.2 Detailed Preparation
Here we use the ziya-llama-13b-v1 model as an example to illustrate the complete data preparation process.
**2.2.1 Raw Data**
First download sample data:
```shell
wget https://paddlenlp.bj.bcebos.com/datasets/PDC_DATASETS/PRETRAIN/zh_sample.txt
```
Convert to jsonl format:
```shell
python trans_to_json.py \
--input zh_sample.txt \
--output zh_sample.json \
--workers 8
```
For large files (recommended processing method):
```shell
split -l 10000 zh_sample.txt -d -a 3 zh_part_
ls zh_part_* | xargs -I {} -P 8 python trans_to_json.py --input {} --output {}.json
cat *.json > zh_sample_all.json
rm zh_part_*
```
```
mkdir data && cd data
wget https://bj.bcebos.com/paddlenlp/models/transformers/data_tools/baike.txt
cd ..
```
**2.2.2 Convert Raw Data to jsonl Format**
Use trans_to_json.py to convert data into json string format. Below is the script usage instructions:
```bash
optional arguments:
-h, --help
--input_path INPUT_PATH
"Required. Can be a directory or single file. By default searches up to two subdirectory levels in folders."
--output_path OUTPUT_PATH
"Required. Output filename."
--json_key JSON_KEY
"Recommended to keep default. Default key is 'text'"
--doc_spliter DOC_SPLITER
"Article delimiter. Can be modified according to actual needs. Default uses blank lines as article delimiter."
--min_doc_length MIN_DOC_LENGTH
"Optional. Filter articles shorter than this length. Default 10"
--workers WORKERS
"Optional. Multi-process conversion for scenarios with large number of files in input_path."
"Each file will be processed by different workers"
--log_interval LOG_INTERVAL
"Optional. Here interval refers to the number of processed files between logging."
--no-merge
"Optional. By default not enabled. Default behavior merges converted jsonl texts from all files into single output file."
--no-shuffle
"Optional. By default not enabled. Default shuffles processed documents."
```
Using the instructions, we execute the following command to obtain baike_sample.jsonl file. Here we shuffle all documents:
```
python trans_to_json.py --input_path ./data --output_path baike_sample
```
Check data:
```json
{"text": "China's process of emulating Western industrial development began to progress smoothly from the establishment of the Nationalist Government of the Republic of China until the eve of the Sino-Japanese War, despite multiple interruptions from internal and external factors. It was not until the conclusion of the Sino-Japanese War and the Chinese Civil War that China entered a relatively prolonged period of peaceful development.\nSince the 1980s, the Deng Xiaoping administration announced the reform and opening-up policy, initiating the implementation of a socialist market economy and promoting economic system reforms. By 2010, mainland China's GDP had exceeded $7.2 trillion, becoming the world's second-largest economy after the United States. While China is widely recognized as the world's fastest-growing economy, its per capita gross national product remains at a medium level globally (ranked 89th), and it faces increasing constraints from resource limitations and widening wealth disparity. Among China's provinces, Guangdong ranks first in GDP, while Zhejiang is the wealthiest province in terms of per capita income. Economic ties between mainland China, Hong Kong, Macau, and Taiwan have grown increasingly close in the process of globalization.\n"}
```
**2.2.3 Data ID Processing**
In this section, we use the `create_pretraining_data.py` script to perform tokenize and ID conversion on the previously obtained `baike_sample.jsonl`. Models can reference existing vocabulary lists.
```bash
optional arguments:
--model_name MODEL_NAME
"Must be specified, e.g.: idea-ccnl/ziya-llama-13b-v1"
--tokenizer_name {LlamaTokenizer}
"Tokenizer corresponding to the model. Llama models require LlamaTokenizer"
data input/output:
--input_path INPUT_PATH
"Must be specified. Directory of input jsonl files"
--output_prefix OUTPUT_PREFIX
"Must be specified. Prefix for output files."
"If name is XXX, outputs will be XXX.bin and XXX.idx."
"bin file: tokenized data; idx file: sentence/document position indices."
--data_format {JSON}
"No need to set. Currently only processes jsonl format by default"
--json_key JSON_KEY
"Key for text strings in json. Same as json_key in trans_to_json.py, default 'text'"
--split_sentences
"Whether to split documents into sentences. Generally not needed for GPT."
--data_impl
"Processed data format. Options: 'mmap' or 'lazy',"
"where 'mmap' creates memory mapping during training, 'lazy' reads directly from file."
chinese words:
--chinese
"Required if split_sentences is set and processing Chinese text."
--cn_whole_word_segment
"Optional. Whether to apply Whole Word Masking (WWM). Generally not needed for GPT models."
--cn_seg_func {lac,seg,jieba}
"Default: jieba (faster). lac model is more accurate but computationally intensive."
--cn_splited
"Optional. For pre-segmented text. When set, cn_seg_func is disabled."
"E.g. pre-segmented text: '中国 效仿 西方 发展 工业 的过 程'"
--cn_split_dimer CN_SPLIT_DIMER
"Used with cn_splited. Default delimiter is whitespace."
common config:
--append_eos
"GPT-specific. Adds EOS token at document end for GPT models."
--log_interval LOG_INTERVAL
"Logging interval (number of processed lines/docs between logs)"
--workers WORKERS
"Number of processes for text tokenization."
```
We can obtain the processed pre-training data through the following training script:
```bash
python -u create_pretraining_data.py \
--model_name "idea-ccnl/ziya-llama-13b-v1" \
--tokenizer_name "LlamaTokenizer" \
--data_format "JSON" \
--input_path "/home/data/baike_sample.jsonl" \
--append_eos \
--output_prefix "/home/data/baike_sample" \
--workers 1 \
--log_interval 5 \
--data_impl "mmap"
```
1. If using pre-tokenized corpus, set `--cn_split` to True and specify `--cn_split_dimer` (e.g., space).
2. For custom vocabulary, set model_name to the directory containing the vocabulary.
After processing, we obtain preprocessed training data baike_sample.bin and document index file `baike_sample.idx` in the "/home/data/" directory.
**2.2.4 (Optional) Merge Datasets**
For large input files requiring preprocessing, the processing time might be excessively long. In such cases, consider splitting the jsonl file into multiple smaller files, process them in parallel using create_pretraining_data.py, and then merge the resulting .bin & .idx files using the following merge script. Merging two 500GB files into 1TB typically takes about 1 hour.
```bash
python merge.py \
--input "/home/data/" \
--output-prefix "/home/data/merged" \
--data_impl mmap
```
Usage:
```bash
arguments:
--input INPUT_PATH
"Directory containing files to be merged. Files should be named in the order required for merging"
"E.g., 1.bin/1.idx, 2.bin/2.idx..."
--output_prefix OUTPUT_PREFIX
"Prefix for merged output files. Given prefix XXX, will generate XXX.bin and XXX.idx".
--data_impl {mmap,lazy}
"Data format before/after merging. Options: 'mmap' or 'lazy'. All input files must have consistent format."
```
After processing with the above merge script, the "/home/data" directory will contain merged.bin and merged.idx files, which are combined from the small files in "/home/data/".
**Note: A single dataset should not be too large to avoid int32 overflow. It is recommended that the number of docs in a single file does not exceed 500 million.**

tar -xvf alpaca_demo.gz
```
The supported fine-tuning data format is a json file where each line contains a dictionary with the following fields:
- `src`: `str, List(str)`, represents the model's input instruction (prompt) that the model should execute.
- `tgt`: `str, List(str)`, represents the model's output.
Sample data:
```
{"src": "Type#Dress*Color#Blue*Style#Fresh*Pattern#Bow", "tgt": "The dress features 3D bow decorations with blue ribbon details, creating a full and layered silhouette while adding a touch of sweetness. This highlights the girl's fresh and charming appearance."}
...
# You can prepare your own fine-tuning data following this format.
```
### LoRA Fine-tuning
You can use the following script to start LoRA fine-tuning:
```bash
PYTHONPATH=.. python run_finetune.py dcu/llama/lora_argument.json
```
### SFT Fine-tuning
For Lsft fine-tuning training, you may refer to the following hyperparameters:
```bash
PYTHONPATH=.. python run_finetune.py dcu/llama/sft_argument.json
```
## 3. Pre-training
### Data Preparation

Example: OpenWebText2 pre-training data preparation refers to [here](https://paddlenlp.readthedocs.io/zh/latest/llm/pretraining/data/OpenWebText2.html).
For user convenience in testing, this project provides processed 100k doc training samples:
```bash
cd PaddleNLP/llm/
mkdir data && cd data
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.bin
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.idx
cd .. && tree data
data
├── llama_openwebtext_100k.bin
└── llama_openwebtext_100k.idx
```
- **Note:** Distinguish path from fine-tuning dataset
### Execution Script
This training script can run on single-node or multi-node environments, with 8 DCU-K100AI-64G per node.
Parallel configuration uses TP 1, PP 8, with fp16 precision for pre-training.
Refer to the following script to start pre-training:
```bash
python -m paddle.distributed.launch \
--gpus '0,1,2,3,4,5,6,7' \
run_pretrain.py dcu/llama/pretrain_pp8.json
```

### (1) Environment Preparation: (This will take 5~55 minutes)
1. Pull the Docker image
```bash
# Please contact Iluvatar CoreX customer support (services@iluvatar.com) to obtain the SDK image
docker pull 10.150.9.98:80/sw_test/sw_home:4.1.0.20240528.110-x86_64-py3.10-bi150
```
2. Start the container with the following command
```bash
docker run -e USER=`id -u -n` -e USER_ID=`id -u` --name paddle-corex-dev -it --privileged --cap-add=ALL --pid=host --network=host -v /data1:/data1 --mount type=volume,dst=/home/`id -u -n`/.local bdkw:paddle-corex /bin/bash
```
3. Install PaddlePaddle
① If you have already obtained the PaddlePaddle installation package through Iluvatar CoreX (services@iluvatar.com), you can install it directly:
```bash
pip3 install paddlepaddle-2.5.2+corex*.whl
```
② You can also compile the PaddlePaddle installation package from source. Please ensure you have correctly installed the Iluvatar CoreX software stack.
```bash
# 1. Clone the Paddle4CoreX GitHub repository and switch to the BDKW/2.5.2_corex branch.
git clone --recurse-submodules -b BDKW/2.5.2_corex https://github.com/PaddlePaddle/Paddle4CoreX.git
# 2. Execute the compilation script
bash build_paddle.sh
# 3. Run the installation script after compilation completes
bash install_paddle.sh
```
4. Clone the PaddleNLP repository and install dependencies
```bash
# PaddleNLP is a natural language processing and large language model (LLM) development library based on PaddlePaddle. It contains various large models implemented using PaddlePaddle, including the llama-13B model. To facilitate your usage, you need to clone the entire repository.
git clone -b sci/benchmark_iluvatar https://github.com/tianyuzhou668/PaddleNLP.git

cd PaddleNLP
cd ./model_zoo/gpt-3/external_ops/ && python3 setup.py install && cd -
# Install PaddleNLP
python3 -m pip install -r requirements.txt
python3 -m pip install -e .
```
### (2) Data Preparation: (This will take 2~5 minutes)
To facilitate users in running tests for this model, we provide a pre-processed 100k doc training sample:
```bash
wget https://paddlenlp.bj.bcebos.com/data/gpt_en_dataset_300m_ids.npy
wget https://paddlenlp.bj.bcebos.com/data/gpt_en_dataset_300m_idx.npz
```
```bash
# Downloading Llama Model Data
cd ./llm
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.bin
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.idx
```
You can also download the complete dataset:
```bash
cd ./llm
wget https://paddlenlp.bj.bcebos.com/datasets/PDC_DATASETS/PRETRAIN/openwebtext2/llama/mmap/llama_mmap.bin
wget https://paddlenlp.bj.bcebos.com/datasets/PDC_DATASETS/PRETRAIN/openwebtext2/llama/mmap/llama_mmap.idx
```
Place all preprocessed files into a single directory for training:
```bash
mkdir data
mv llama_openwebtext_100k_ids.npy ./data
mv llama_openwebtext_100k_idx.npz ./data
```
### (3) Pre-training:
We provide a corresponding 4-node pre-training script in this directory, which has been optimized with parallel strategies and configurations for 32 BI150 chip resources. The detailed steps to start pre-training are as follows:
```bash
# You need to replace the node IP addresses in the script with your actual node IPs
bash run_node4.sh
```
By default, we will train for 5000 steps. After completing the 5000-step training, the model will perform evaluation and generate the final checkpoint. You can use this checkpoint for fine-tuning tasks or directly proceed with inference tasks.

```
### (1) Environment Preparation: (This will take 5-15 minutes)
1. Pull the image
```# Note this image is for development environment only; the image does not contain precompiled PaddlePaddle packages
docker pull registry.baidubce.com/device/paddle-npu:cann80RC1-ubuntu20-x86_64-gcc84-py39
```
2. Start the container with the following command. You can specify visible Ascend NPU cards for the container using ASCEND_RT_VISIBLE_DEVICES
```

registry.baidubce.com/device/paddle-npu:cann80RC1-ubuntu20-x86_64-gcc84-py39 /bin/bash
```
3. Install PaddlePaddle
```
# PaddlePaddle, the deep learning framework, provides fundamental computing capabilities
python -m pip install paddlepaddle==3.0.0b0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
```
4. Install paddleCustomDevice
```
# paddleCustomDevice is the custom hardware backend implementation for PaddlePaddle, providing NPU operator implementations.
python -m pip install paddle-custom-npu==3.0.0b0 -i https://www.paddlepaddle.org.cn/packages/stable/npu/
# For source compilation and installation, please refer to https://github.com/PaddlePaddle/PaddleCustomDevice/blob/develop/backends/npu/README_cn.md
```
5. Clone PaddleNLP repository and install dependencies
```
# PaddleNLP is a natural language processing and large language model (LLM) development library based on PaddlePaddle, containing various large models implemented with PaddlePaddle, including the llama2-13B model. To better utilize PaddleNLP, you need to clone the entire repository.
git clone https://github.com/PaddlePaddle/PaddleNLP.git
cd PaddleNLP
python -m pip install -r requirements.txt
python -m pip install -e .
```
6. Install paddlenlp_ops
```
# The PaddleNLP repository includes built-in Ascend-specific fused operators to help users enjoy the ultimate compression of inference costs
```
cd csrc/npu
python setup.py build bdist_wheel
pip install dist/paddlenlp_ops-0.0.0-cp39-cp39-linux_x86_64.whl
cd -
```
### (2) Data Preparation: (This will take 2-5 minutes)
sft is the fine-tuning strategy. We provide an advertising generation dataset demo for your debugging:
```
# Fine-tuning: For testing convenience, we provide an advertising generation dataset ready to use:
cd llm/devices/npu/llama
wget https://bj.bcebos.com/paddlenlp/datasets/examples/AdvertiseGen.tar.gz
tar -zxvf AdvertiseGen.tar.gz
```
The supported fine-tuning data format is a json file where each line contains a dictionary with the following fields:
- `src`: `str, List(str)`, represents the model's input instruction (instruction), prompt, or task description.
- `tgt`: `str, List(str)`, represents the model's expected output.
Sample data:
```
{"src": "Type#Dress*Color#Blue*Style#Fresh*Pattern#Bowknot", "tgt": "The dress features 3D bowknot decorations with blue ribbon accents, creating a full, layered silhouette while adding a touch of sweetness. This design highlights the girl's fresh and charming demeanor."}
...
# You can prepare your own fine-tuning data following this format.
```
### (3) Training: (This will take approximately 4 hours)
We provide three entry scripts for Pretrain/SFT/LoRA in this directory, optimized with parallel strategies and configurations for 8x910 chip training resources. Detailed steps to launch fine-tuning:
```
# Run SFT strategy
bash llama_npu_sft_N1C8.sh
```
### (4) Inference: (This will take 10-15 minutes)
Before inference, prepare the configuration file. Under the merged parameter path (tutorial path: `./output/sft_bf16_llama_N1C8`), modify `config.json` as follows:
```
{
"architectures": [
"LlamaForCausalLM"
],
"bos_token_id": 1,
eos_token_id": 2,
"hidden_act": "silu",
"hidden_size": 5120,
"initializer_range": 0.02,
"intermediate_size": 13824,
"max_position_embeddings": 4096,
"model_type": "llama",
"num_attention_heads": 40,
"num_hidden_layers": 40,
"num_key_value_heads": 40,
"pad_token_id": 0,
"pretraining_tp": 1,
"rms_norm_eps": 1e-05,
"rope_scaling": null,
"tie_word_embeddings": false,
"torch_dtype": "float16",
"transformers_version": "4.31.0",
"use_cache": false,
"vocab_size": 32000
}
```
To ensure minimal inference costs with extreme compression, we employ static graph implementations. Therefore, it is necessary to export the static graph model from the dynamically trained model. Execute the following command to perform the export:
```
bash export_npu.sh ./output/sft_bf16_llama_N1C8/ ./inference
```
Finally, we execute inference through the static graph model:
```
# Execute inference code
bash predict_npu.sh ./inference
```
Upon successful execution, the generated inference results can be observed. A sample output is as follows:
"温故而知新" (wēn gù ér zhī xīn) is a Chinese idiom that means "to review the old and know the new." It is often used to describe the idea of gaining new insights through revisiting past knowledge.
The characters break down as:
- 温 (wēn): "to review/revisit"
- 故 (gù): "the old/past"
- 知 (zhī): "to know/understand"
- 新 (xīn): "the new"
This proverb originates from Confucius' *Analects* (《论语》): "温故而知新，可以为师矣" - "He who reviews old knowledge and gains new understanding can become a teacher."
The idiom emphasizes:
1. The value of historical knowledge
2. The process of deriving new understanding from existing foundations
3. The importance of continuous learning through reflection and synthesis
In modern contexts, it's used to advocate for:
- Learning from past experiences
- Re-examining historical data with fresh perspectives
- Combining traditional wisdom with innovative thinking
## 💪🏼 Features 💪🏼
- **Communication Hiding Technology**
When enabling tensor parallelism during model training, numerous communication (AllReduce/ReduceScatter/AllGather) + matrix multiplication (Matmul) operator combinations emerge. The 910 chip provides an efficient parallel mechanism to hide communication overhead.
<!-- Placeholder for principle diagram -->
By setting `FLAGS_NPU_MC2=1`, the communication-computation fusion pass is activated, effectively hiding the majority of tensor parallelism communication overhead within computations, thereby enhancing training performance.
<!-- Placeholder for performance chart -->
<!-- Placeholder for profiling chart -->
- **Unified Abstraction for Custom Operators**
In practice, we observe that fusion operators significantly impact large model training performance. To comprehensively support high-performance operators on Ascend and other hardware while maintaining concise network code, we provide a unified [custom operator interface implementation](https://github.com/PaddlePaddle/PaddleNLP/blob/develop/paddlenap/transformers/llama/fusion_ops.py). Current implementations cover common `fusion_rope`, `fusion_rms_norm`, and `fusion_flash_attention` for NPU, GPU, XPU, and GCU.
- **Layer-level Operator Fusion**
Layer-level operator fusion significantly enhances computational efficiency. The fused operators support dynamic insertion. During inference execution, the following logs can be observed:
```
--- Running IR pass [remove_residual_in_fused_bias_residual_layernorm]
--- Running IR pass [remove_residual_in_rms_norm]
--- Running IR pass [remove_blha_get_max_len]
--- Running IR pass [llama_fuse_attention_layer_begin]
--- Running IR pass [llama_fuse_attention_layer_end]
--- Running IR pass [llama_fuse_attention_layer]
--- Running IR pass [llama_fuse_lm_head_with_slice]
--- Running IR pass [llama_fuse_lm_head]
--- Running IR pass [llama_fuse_get_padding_offset]

Explain the meaning of "温故而知新"
***********Target**********
***********Output**********
"温故而知新" (wēn gù er zhī xīn) is a Chinese idiom that means "to understand the old in order to know the new." It is often used to convey the idea that one must have a deep understanding of the past and traditional ways of doing things in order to truly appreciate and understand new ideas and innovations.
The phrase is often used in the context of education, where students are encouraged to study the classics and learn from the past in order to gain a solid foundation for understanding new concepts and ideas. It is also used in business and technology, where companies may look to the past for inspiration and guidance as they develop new products and services.
In essence, "温故而知新" suggests that one cannot truly understand the new without first understanding the old, and that a deep appreciation for the past is essential for making progress and innovation.

Explain "温故而知新"
***********Target**********
***********Output**********
"温故而知新" (wēn gù ér zhī xīn) is a Chinese idiom that translates to "Gaining new insights by reviewing the old." This phrase originates from the Confucian classic "The Analects" (《论语》), specifically from Book II, Chapter 11. It embodies the concept of deriving fresh understanding through the study of past knowledge and experiences.
The idiom can be broken down as:
- 温 (wēn): To review or revisit
- 故 (gù): The old, past knowledge
- 知新 (zhī xīn): To acquire new knowledge
This principle emphasizes that:
1. Historical knowledge serves as foundation for innovation
2. Past experiences can inform present decisions
3. Continuous learning requires building upon existing understanding
Modern applications include:
- Technical fields: Reusing and improving upon existing codebases
- Academic research: Building upon previous studies to make new discoveries
- Business strategy: Analyzing past market trends to predict future patterns
For example, in software development, a programmer might say: "By refactoring legacy code (温故), we discovered more efficient algorithms (知新)." This demonstrates how revisiting existing implementations can lead to technical innovations.

Explain "Reviewing the past to learn the new"
***********Target**********
***********Output**********
"Reviewing the past to learn the new" (wēn gù ér zhī xīn) is a Chinese proverb that emphasizes the importance of understanding historical knowledge to better comprehend new concepts. The phrase consists of two parts: "温故" (wēn gù) meaning "to review the old", and "知新" (zhī xīn) meaning "to learn the new". This proverb suggests that by re-examining and consolidating previous knowledge, one can gain deeper insights and make more informed judgments when encountering new information or situations.
In practical terms, this means:
1. Foundational knowledge serves as a basis for understanding new developments
2. Historical context helps prevent hasty dismissal of traditional wisdom
3. A balanced approach allows for integration of old and new knowledge
For example:
- In language learning, studying etymologies and historical grammar can enhance understanding of modern usage
- In technical fields, mastering fundamental principles is crucial before exploring advanced innovations

# Introduction to Common Algorithms in PaddlePaddle Large Models
## 1. Training Acceleration Strategies
### 1.1 Greedy Zero Padding
<div align="center">
<img width="500" alt="llm" src="https://github.com/user-attachments/assets/4b69f8ac-ba3f-4dd6-bdaf-3a7386cb09ad">
</div>
Padding input sequences to the same length is a common approach when handling mini-batch inputs during training. However, this method introduces irrelevant padding tokens, typically resulting in a padding token ratio of about 50%. The Zero Padding strategy proposes concatenating multiple texts into long sequences within single data instances, while using attention_mask to ensure precision alignment, thereby reducing the padding token ratio to 20%. Building upon Zero Padding, PaddlePaddle's self-developed Grouped Greedy Zero Padding strategy further reduces the padding token ratio to approximately 5% through data grouping and greedy combination search.
To enable Zero Padding during fine-tuning/DPO training, simply set `zero_padding` to `True` in the configuration. To activate Grouped Greedy Zero Padding, additionally set `greedy_zero_padding` to `True`.
### 1.2 FlashAttention2
<div align="center">
<img width="500" alt="llm" src="https://github.com/user-attachments/assets/8d87bf43-9c9c-4be5-9d1b-520fe735934b">
</div>
[FlashAttention2](https://tridao.me/publications/flash2/flash2.pdf) is a faster and more optimized self-attention computation method. The computational complexity and memory footprint of native self-attention mechanisms are both O(N²), which can lead to memory bottlenecks and low computational efficiency in long-context scenarios. FlashAttention2 introduces tiling to partition long sequences into smaller blocks, reducing memory consumption while leveraging parallel computing to improve computational efficiency.
The standard attention mechanism uses High Bandwidth Memory (HBM) to store, read, and write keys, queries, and values. While HBM offers larger capacity, its access speed is slower compared to the faster but smaller SRAM. In standard attention implementations, the cost of loading and writing keys/queries/values from HBM is significant. FlashAttention2 loads keys, queries and values from HBM to GPU's on-chip SRAM only once, fuses the attention computation steps, and writes back to HBM just once, achieving significant optimization.
```
# FlashAttention2 Usage Example
from paddlenlp.transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained(
model_name_or_path,
dtype=dtype,
use_flash_attention=True
)
```
To enable FlashAttention2 during fine-tuning/DPO training, simply set `use_flash_attention` to `True`.
To enable FlashAttention2 acceleration during training, simply configure `flash_attention` to `True` in the model configuration.
### 1.3 FlashMask
<div align="center">
<img width="500" alt="llm" src="https://github.com/user-attachments/assets/2867b49b-297b-42ea-88d5-1bbfc29f61d6">
</div>
FlashMask is an attention mechanism optimization algorithm independently developed by PaddlePaddle. Based on FlashAttention2, it introduces column-wise sparse mask representation to support various complex masks while maintaining accuracy. This reduces the complexity of attention mask representation from O(N<sup>2</sup>) to O(N), lowering training memory consumption. During block computation, it dynamically skips computation, applies masks, or omits masks based on mask conditions, thereby improving computational efficiency and enhancing training throughput for long contexts.
To enable FlashMask acceleration during fine-tuning/DPO training, simply add `flashmask=True` to the configuration while setting `use_flash_attention=True`.
## 2. Improved Fine-Tuning Strategies
### 2.1 NEFT
[NEFT](https://arxiv.org/abs/2310.05914) proposes adding controlled noise to model embeddings during training to improve fine-tuning performance. To enable NEFT training, simply configure `neftune=True` and set the noise intensity parameter `neftune_noise_alpha` in the configuration.
### 2.2 LoRA+
[LoRA+](https://github.com/user-attachments/assets/f367bf06-ad2f-4d41-8b5a-6508f90b46fa) proposes using different learning rates for matrices A and B during LoRA training to accelerate convergence. Configure the learning rate ratio between B and A using the `lora_plus_scale` parameter.
### 2.3 rsLoRA
[rsLoRA](https://arxiv.org/pdf/2312.03732) suggests that for improved LoRA performance, the LoRA rank should increase while maintaining the scaling-ratio relationship according to:
$$
\gamma_r \in \Theta_r\left(\frac{1}{\sqrt{r}}\right)
$$
Enable this by setting `rslora=True` during LoRA training.
### 2.4 PiSSA
<div align="center">
<img width="500" alt="llm" src="https://github.com/user-attachments/assets/d75ec708-2c40-4a12-8a01-17b9f276ba20">
</div>
[PiSSA](https://arxiv.org/abs/2404.02948) is an optimization work based on LoRA, sharing the same architecture. The A and B matrices are initialized through singular value decomposition (SVD) of the pre-trained model weights, with the residual matrix initializing the backbone weights. During training, the backbone weights remain frozen while updating matrices A and B (i.e., the principal components), achieving faster convergence and higher performance. Utilizing fast SVD technology, PiSSA's initialization requires only a few seconds, adding almost no cost when switching from LoRA to PiSSA.
To enable PiSSA during fine-tuning, simply set `pissa=True` in the LoRA training configuration.
### 2.5 VeRA
<div align="center">
<img width="500" alt="llm" src="https://github.com/user-attachments/assets/343acc9e-46a0-4a39-91cd-71e433ee59b2">
</div>
[VeRA](https://arxiv.org/abs/2310.11454) is a parameter-efficient fine-tuning technique similar to LoRA, but requiring fewer additional parameters while promising comparable or better performance. This makes VeRA particularly useful when parameter budgets are extremely limited, such as when scaling to very large models. The reduction in trainable parameters is achieved by sharing the same low-rank matrix across all layers, with only two additional vectors trained per layer.
To enable VeRA during fine-tuning, simply set `vera=True` and configure the corresponding `vera_rank` parameter.

# Multi-Turn Dialogue Fine-Tuning Tutorial
With the increasing availability of open-source Chat-type models, PaddleNLP has integrated [Llama](../config/llama), [Qwen](../config/qwen), [ChatGLM](../config/chatglm) and other model series, while also supporting [Multi-Turn Dialogue Prompt Template Inference](https://paddlenlp.readthedocs.io/zh/latest/get_started/chat_template.html). By simply calling the `apply_chat_template` function, we can construct prompts that concatenate dialogue history and the user's latest query according to each model's specified rules, enabling customized prompt-based inference for different models.
Moreover, there is a growing need for fine-tuning multi-turn dialogue training. As different models have distinct template construction rules for multi-turn dialogues, we designed `chat_template` to standardize pre-processing differences on the training side.
### How to Construct `chat_template`
Simply add a `chat_template` configuration to enable multi-turn dialogue fine-tuning training for the model. Taking the `qwen-14b-chat` configuration file as an example:
> The following configuration references: https://huggingface.co/Qwen/Qwen-14B-Chat/blob/main/qwen_generation_utils.py#L119
```json
{
"system": "You are a helpful assistant.",
"conversation": ["\n<|im_start|>user\n{{user}}<|im_end|>\n<|im_start|>assistant\n", "{{bot}}<|im_end|>"],
"query": "\n<|im_start|>user\n{{query}}<|im_end|>\n<|im_start|>assistant\n",
}
```
Key Notes:
1. The configuration file is named `chat_template.json` by default.
2. The `query` and `conversation` fields are mandatory in the `chat_template.json` configuration. Their contents are highly similar, mainly designed to handle inference and training scenarios respectively: `query` is used solely for inference, while both `query` and `conversation` are used for training.
3. During both training and inference, special token markers (e.g., bos_token, eos_token, and custom markers like `<|im_start|>`) are added to the text. Therefore, tokenization based on `chat_template` does not add special tokens, meaning the `add_special_tokens` parameter in the tokenizer must always be set to `False`.
4. The `conversation` field must be an array with exactly two elements, corresponding to the User and Bot dialogue content respectively. The former does not participate in loss calculation during training, while the latter does.
5. During training, the length of the `system` text cannot exceed `max_length`. For single-turn dialogues, truncation is performed at the token level using pseudo-code: `(system_tokens + conversation_tokens)[:max_length]`.
# How to Use `chat_template` for Training
Using the `qwen-14b-chat` base model as an example, first we need to adjust the training data to ensure the following format:
```json
{"src": ["user-1", "user-2", ..., "user-n"], "tgt": ["bot-1", "bot-2", ..., "bot-n"]}
...
```
Next, pass the constructed `chat_template.json` file to the `llm/run_finetune.py` module:
* Using the model's built-in chat-template
> Note: Not all models support chat-template. PaddleNLP is actively working on compatibility. You can check if a model supports chat-template by verifying the presence of the `chat_template.json` file.
```shell
python run_finetune.py ... --model_name_or_path qwen/qwen-7b-chat --chat_template qwen/qwen-7b-chat
```
When the `chat_template` parameter matches `model_name_or_path`, the system will automatically use the model's built-in `chat_template.json` file.
* Using a custom chat-template
```shell
python run_finetune.py ... --chat_template ./qwen_14b_chat_template.json
```
1. When `chat_template` and `model_name_or_path` parameters are identical, the system defaults to using the model's built-in `chat_template.json`.
2. When `chat_template` specifies a file path, the system uses the template configuration from that file.
3. When `chat_template` is unspecified, the system will not use any chat-template configuration during training.
# How to Customize System Prompt
To dynamically adjust the system prompt during training or inference:
1. Ensure the `chat_template.json` file's system configuration contains Jinja2 variable placeholders (e.g., `{{user}}` in `<|im_start|>user\n{{user}}<|im_end|>`), while maintaining default parameters. For example:
> Developers must manually modify `chat_template.json` to enable dynamic system prompt adjustments.
```json
{
"system": "<|im_start|>system\n{{system_prompt}}<|im_end|>\n",
"conversations": [
{"role": "user", "content": "<|im_start|>user\n{{content}}<|im_end|>\n"},
{"role": "assistant", "content": "<|im_start|>assistant\n{{content}}<|im_end|>\n"}
]
}
```
2. When initializing the tokenizer, pass the `system_prompt` parameter:
```python
from paddlenlp.transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("qwen/qwen-7b-chat", system_prompt="You are a helpful assistant.")
```
This allows dynamic modification of the system prompt during both training and inference.
diff
{
- "system": "You are a helpful assistant.",
+ "system": "{{system | 'You are a helpful assistant.'}}",
"conversation": ["\n<|im_start|>user\n{{user}}<|im_end|>\n<|im_start|>assistant\n", "{{bot}}<|im_end|>"],
"query": "\n<|im_start|>user\n{{query}}<|im_end|>\n<|im_start|>assistant\n",
}
```
2. The training text data requires configuration of the `context` field to pass in the `system` field. Sample data format:
```json
{"src": ["user-1", "user-2", ..., "user-n"], "tgt": ["bot-1", "bot-2", ..., "bot-n"], "context": {"system": "You are an AI assistant skilled at task completion"}}
...
```
When rendering the chat_template, use the `context` data as Jinja2 context variables. This allows customizing the system prompt for each training data instance.

# PaddlePaddle Large Model Suite DPO Documentation
## 1. Algorithm Introduction
Direct Preference Optimization (DPO) is an improvement over Reinforcement Learning from Human Feedback (RLHF). It demonstrates the mapping relationship between the reward function and the optimal policy, proving that this constrained reward maximization problem can be precisely optimized through single-stage policy training. DPO simplifies the training process and enhances model convergence stability.
Based on DPO, several derivative algorithms have been developed, such as SimPO, ORPO, etc. We can directly switch between different algorithms by modifying the loss_type configuration.
## 2. Quick Start
Next, we will use **Llama 3** as an example to demonstrate how to use the unified script for DPO.
### 2.1 Environment Preparation
- PaddlePaddle 3.0-beta
- PaddleNLP develop
- PaddleSlim develop
Clone the code to your local machine to begin:
```bash
git clone https://github.com/PaddlePaddle/PaddleNLP.git
# pip install ./PaddleNLP (use develop version)
cd PaddleNLP/llm
# Proceed to runtime directory
```
### 2.2 Data Preparation
We support preference data format as JSON files where each line contains a dictionary with the following fields:
- `src`: `str, List(str)`, User conversation content.
- `tgt`: `str, List(str)`, System response content.
- `response`: `str, List(str)`, Contains chosen and rejected responses.
- `sort`: `List(int)`, The sort value distinguishes between chosen and rejected responses in response (smaller sort value indicates rejected, larger indicates chosen).
Sample data:
```json
{
"src": "How to implement DPO?",
"tgt": "Refer to the DPO documentation.",
"response": [
{"text": "Use the DPO example code.", "sort": 2},
{"text": "Read the paper for details.", "sort": 1}
]
}
```
```text
{
"src": ["In this task, you are given a second sentence. Your task is to generate the first sentence on the same topic but incoherent and inconsistent with the second sentence.\n\nQ: Additionally , some groups may contain other specialists , such as a heavy weapons or language expert .\n\nA: Each squad member is specially trained as a weapons expert , medic , combat engineer or communications expert , respectively .\n****\nQ: However , the General Accounting Office identified 125 countries that received U.S. training and assistance for their police forces during fiscal year 1990 at a cost of at least $117 million .\n\nA: No government agency is in charge of calculating the cost .\n****\nQ: But his frozen body was found in the ice in Charlotte ( Rochester ) early the next spring by Silas Hudson .\n\nA:"],

Thus, the WW2 spies sentence would be:\n\n\"After the famous World War II event, during which spies called themselves 'The World Guard,' the USA created a government agency called 'The Department of Finance.' Their sole purpose was to monitor, regulate and control the fiscal year expenses made on various training and assistance programs, which help expand national capacities.\"\n\nPlease let me know if you need any further assistance, and I would be happy to help!"

# PaddlePaddle Large Model Fine-Tuning Documentation
## 1. PaddlePaddle Fine-Tuning Features
Large Model Fine-Tuning (Supervised Fine-Tuning, SFT) is a crucial component of Large Language Models (LLMs). Its primary objectives are to enable models to follow instructions and generate expected responses, effectively enhance the performance of general models in specific domains and application scenarios, and better meet personalized applications of large models. This method is used to improve and customize pre-trained large language models.
- **Easy-to-Use Parallel Strategies**: Supports pure Data Parallelism, Sharding Parallelism, Tensor Parallelism, Pipeline Parallelism, and Sequence Parallelism.
- **Multiple Precision Training**: Full-parameter fine-tuning with 16/32-bit, LoRA fine-tuning with 4/8/16-bit, and mixed-precision quantized LoRA.
- **Extreme Performance Optimization**: FlashAttention-2, FlashMask, Greedy Zero Padding.
- **Advanced Fine-Tuning Strategies**: LoRA+, PiSSA, rsLoRA, NEFTune, VeRA, MoRA, ReFT, MoSLoRA.
For more algorithm details, please refer to [PaddlePaddle Large Model Algorithm Documentation](algorithm_overview.md).
## 2. Introduction to Large Model Fine-Tuning
Here we introduce commonly used SFT techniques:

Principles of Large Model Fine-Tuning
</font>
</div>
- **Full-Parameter Fine-Tuning**: The most common SFT technique, retraining all parameters of the pre-trained model on instruction datasets. This method typically delivers the best results but requires substantial computational resources.
- **LoRA**: Low-Rank Adaptation is the most widely used Parameter-Efficient Fine-Tuning (PEFT) technique. Instead of retraining the entire model, it freezes original weights and introduces low-rank matrices to each target linear layer. This reduces the number of trainable parameters by over 99%, significantly decreasing memory usage and training time.
- **QLoRA**: Quantization-Aware Low-Rank Adaptation reduces memory usage by up to 33% compared to standard LoRA, making it particularly useful in GPU memory-constrained scenarios. QLoRA typically takes about 20% more time than regular LoRA, but its significant memory savings make it the only viable option when GPU memory is limited.
## 3. Quick Start
Next, we will use **Llama 3** as an example to demonstrate how to perform full-parameter SFT and LoRA fine-tuning using a unified script.
### 3.1 Environment Preparation
- PaddlePaddle 3.0-beta
- PaddleNLP 3.0.0b3
- PaddleSlim develop
git clone the code to your local machine, and you're ready to start.
```bash
git clone https://github.com/PaddlePaddle/PaddleNLP.git
# pip install ./PaddleNLP using develop version
cd PaddleNLP/llm
# enter running directory
```
### 3.2 Fine-tuning Data Preparation
For user convenience in testing, we provide an example dataset [Advertisement Generation Dataset](https://bj.bcebos.com/paddlenlp/datasets/examples/AdvertiseGen.tar.gz). Users can also follow the dataset format to create their own datasets for fine-tuning. The supported data format requires each line to contain a dictionary with the following fields:
- `src`: `str, List(str)`, the model's input instruction (instruction), prompt, or the task the model should perform.
- `tgt`: `str, List(str)`, the model's output.
Sample data:
```
{"src": "type#dress*color#blue*style#fresh*pattern#bow", "tgt": "The dress features three-dimensional bow decorations with blue stripes, creating a full and layered silhouette while adding a touch of sweetness. This design highlights the girl's fresh and charming appearance."}
...
```
### 3.3 Full-Parameter Fine-tuning
```
python -u -m paddle.distributed.launch --gpus "0,1,2,3,4,5,6,7" run_finetune.py ./config/llama/sft_argument.json
```
Notes:
1. Setting both `zero_padding` and `greedy_zero_padding` to True helps improve training efficiency. It's recommended to set `per_device_train_batch_size` to 1, control batch size via `gradient_accumulation_steps`, and adjust `max_length` appropriately.
2. Set `use_flash_attention` to True to enable FlashAttention. With FlashAttention enabled, set `flash_mask` to True to enable FlashMask.
3. The SFT API supports 4D parallel strategy. Adjust via `tensor_parallel_degree`, `pipeline_parallel_degree`, `sharding`, and `sharding_parallel_degree`.
### 3.4 PEFT
#### 3.4.1 LoRA/QLoRA
```bash
python -u -m paddle.distributed.launch --gpus "0,1,2,3" finetune_generation.py --config ./config/llama/sft_argument.json --lora ./config/llama/lora_argument.json
# For QLoRA:
python -u -m paddle.distributed.launch --gpus "0,1,2,3" finetune_generation.py --config ./config/llama/sft_argument.json --q_lora ./config/llama/lora_argument.json
```
```bash
# Single-GPU LoRA
python run_finetune.py ./config/llama/lora_argument.json
# Single-GPU QLoRA
python run_finetune.py ./config/llama/qlora_argument.json
# Multi-GPU LoRA
python -u -m paddle.distributed.launch --gpus "0,1,2,3,4,5,6,7" run_finetune.py ./config/llama/lora_argument.json
# Multi-GPU QLoRA
python -u -m paddle.distributed.launch --gpus "0,1,2,3,4,5,6,7" run_finetune.py ./config/llama/qlora_argument.json
```
**Note:**
1. Setting both `zero_padding` and `greedy_zero_padding` to True improves training efficiency. It is recommended to set `per_device_train_batch_size` to 1, use `gradient_accumulation_steps` to control batch size, and adjust `max_length` appropriately.
2. The LoRA strategy is applied to all Linear layers by default.
3. The backbone model can be quantized to low bits by setting `weight_quantize_algo`, e.g., 'weight_only_int4', 'weight_only_int8', 'nf4' or 'fp4'. Refer to the fine-tuning parameter description for details.
4. Set `use_flash_attention` to True to enable FlashAttention. When FlashAttention is enabled, set `flash_mask` to True to enable FlashMask.
5. The LoRA API supports 4D parallel strategy. Adjust the parallel training strategy by controlling `tensor_parallel_degree`, `pipeline_parallel_degree`, `sharding`, and `sharding_parallel_degree`, enabling **LoRA fine-tuning of hundred-billion parameter models on single machines**.
6. Supports algorithms like rsLoRA, LoRa+, PiSSA, and MosLoRA (currently not supporting tensor model parallelism) through parameters `rslora`, `lora_plus_scale`, `pissa`, `lora_use_mixer`, `use_mora`, etc.
To facilitate subsequent **compression** and **static graph inference**, we provide a LoRA parameter merging script that integrates LoRA parameters into the backbone model and saves the corresponding weights.

</div>
<summary>&emsp; Training Parameters (TrainingArguments)</summary><div>

# FlashMask Flexible Attention Mask
In large-scale model training tasks such as Transformers, attention masks (Attention Mask) introduce significant redundant computations on one hand, and due to their $O(N^2)$ memory footprint, make it challenging to achieve efficient training in long-sequence scenarios (where $N$ is the sequence length). While the industry has developed computation acceleration methods like FlashAttention for specific attention masks, their supported attention mask patterns are limited, failing to meet the diverse requirements of large model training. To address these issues, PaddlePaddle's innovative FlashMask technology proposes a column-wise sparse attention mask representation method, supporting flexible and diverse attention mask patterns, thereby reducing the storage complexity from $O(N^2)$ to $O(N)$.
# FlashMask: Flexible Attention Mask for Accelerating Large Language Model Training
We implemented highly efficient operator kernels to maximize the training efficiency of large models, particularly in long sequence scenarios.
We evaluated FlashMask's performance on NVIDIA A100 (80G) GPUs for large language model fine-tuning and alignment training, including SFT, LoRA, DPO, and RM. Compared to existing dense masking methods like FlashAttention, FlashMask achieves significant end-to-end training speed improvements ranging from 1.65x to 3.22x. Additionally, we evaluated its kernel-level performance. FlashMask reaches 37.8% to 62.3% of theoretical maximum FLOPS utilization, and outperforms FlexAttention by 12.1% to 60.7% in kernel-level TFLOPS/s.

## <a name='1'></a>1. Challenges of Large Language Models
With the rapid development of AI technology, Transformer-based large models have demonstrated remarkable capabilities in NLP, computer vision, and multi-modal applications. The attention mechanism plays a crucial role in these models. To determine which Query-Key token pairs require valid attention computation during training, the industry typically uses attention masks. However, current 2D dense matrix representations of attention masks introduce two major issues: (1) redundant computations from unnecessary token-pair attention calculations, and (2) O(N²) space complexity that becomes...
$O(N^2)$ (where $N$ is the sequence length) may cause significant memory pressure in long sequence training scenarios, making efficient training challenging. To address these issues, industry has proposed solutions such as Memory Efficient Attention (MEA) [1] and FlashAttention [2]. However, these solutions support limited types of attention masks. As shown in Figure 1, FlashAttention can only support fixed mask patterns like pure causal mask (Causal), sliding window mask (Sliding Window), causal document mask (Causal Document Mask), and document mask (Document Mask). Yet, actual training tasks often require diverse attention mask patterns, and current technologies struggle to meet the flexibility requirements of attention masks for large models in different training scenarios.

## <a name='2.'></a>2. FlashMask's Innovation: Column-wise Sparse Mask Representation and Efficient Computation
### <a name='2.1'></a>2.1 Key Insight
The core discovery of FlashMask is that in common attention mask patterns of large models, the mask patterns between Query-Key tokens exhibit certain continuity. Specifically, for each Key token, the invalid Query tokens for attention computation are arranged consecutively. That is, in Figure 1, the grayed-out regions along the column direction in the 2D mask matrix correspond to consecutive Query tokens. Based on this insight, FlashMask cleverly converts the 2D dense mask matrix into 1D row index intervals, achieving a more compact representation and significantly reducing memory requirements. We can formalize this as:
$$M_{j} = [start_j, end_j), \quad \forall j \in \{1, \ldots, N\}$$
where $N$ is the sequence length of Keys, $M_j$ represents the $j$-th column of the 2D dense mask matrix, and $[start_j, end_j)$ denotes the consecutive row index interval, indicating that Query tokens from $start_j$ to $end_j - 1$ are masked as invalid for attention computation.
### <a name='2.2'></a>2.2 Column-wise Sparse Mask Representation for Attention
To efficiently handle complex mask patterns in causal and bidirectional attention scenarios, FlashMask proposes a novel column-wise sparse representation. Using the diagonal as a boundary, it employs four 1D vectors to represent masks:
* Lower Triangular Start (LTS)
* Lower Triangular End (LTE)
* Upper Triangular Start (UTS)
* Upper Triangular End (UTE)
Here, the masked row index interval in the lower triangular region is represented by $[LTS, LTE)$, while the upper triangular region uses $[UTS, UTE)$.

<div align="center">
<font size ="2">
Figure 2: Schematic diagram of a more complex 2D dense causal attention mask matrix
</font>
</div>
</div>
As shown in Figure 2, we present a more complex 2D dense causal attention mask matrix when performing attention calculations between 16 Query tokens and 16 Key tokens, where the gray cells represent the masked regions.
This can be expressed using two vectors $[LTS, LTE)$, as shown below:
| col_idx | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
|---------|----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|
| $LTS$ | 13 | 5 | 5 | 5 | 6 | 6 | 9 | 9 | 9 | 12 | 12 | 12 | 16 | 16 | 16 | 16 |
| $LTE$ | 15 | 14 | 14 | 15 | 12 | 12 | 11 | 11 | 16 | 16 | 16 | 16 | 16 | 16 | 16 | 16 |
Taking the first column as an example, the starting row for masking is 13, and the ending row is 15 (open interval), indicating that Query tokens at positions 13 and 14 do not perform valid attention calculations with the Key token at position 0.

As shown in Figure 3, FlashMask uses a columnar sparse mask representation to express all the attention mask patterns from Figure 1. The '-' entries indicate different default values in various scenarios. The default values in $LTS$ and $UTS$ are 0, meaning the masked region starts from row 0 by default, while $LTE$ and $UTE$...
### <a name='2.3'></a>2.3 Extending FlashAttention to Support Complex Masks
FlashMask integrates column-wise mask representation into the FlashAttention-2 algorithm, extending its support for attention masks. The high-performance kernel implementation of FlashMask consists of two key steps: preprocessing and real-time block skipping computation.
In FlashAttention's kernel implementation, the score matrix computation is implemented using tiling. As shown in the simplified representation in Figure 4, the entire score matrix computation is divided into 4x4 tiles, where each tile contains 4 query tokens and 4 key tokens interacting through 4x4 attention computations. FlashMask's original input is token-level column-wise representation, which is converted into tile-level representation during the preprocessing phase. This is used to quickly determine the type of each tile in real-time computation skipping phase.

</div>
</div>
#### <a name='2.3.1'></a>2.3.1 Preprocessing Phase
In FlashMask's preprocessing phase, the column-wise sparse mask vectors $LTS$, $LTE$, $UTS$, $UTE$ are first loaded into high-bandwidth memory (HBM). Then, based on FlashAttention's tile column size, the column-wise sparse mask vectors are tiled. The maximum and minimum values of all columns within each tile are computed, generating 8 intermediate vectors:
* $LTStart^{min}$, $LTStart^{max}$
* $LTEnd^{min}$, $LTEnd^{max}$
* $UTStart^{min}$, $UTStart^{max}$
* $UTEnd^{min}$, $UTEnd^{max}$
Taking the leftmost 4 tiles in Figure 4 as example, a tile contains 4 columns with $LTS=[13,5,5,5]$ and $LTE=[15,14,14,15]$. Therefore, $LTStart^{min}=min(LTS)=5$, $LTStart^{max}=max(LTS)=13$, $LTEnd^{min}=min(LTE)=14$, $LTEnd^{max}=max(LTE)=15$
The remaining computation results are shown in Figure 5:

</font>
</div>
</div>
#### <a name='2.3.2'></a>2.3.2 Real-time Block Skipping Computation Stage
In the real-time computation phase, FlashMask leverages the min/max vectors generated during preprocessing to classify each chunk of the attention score matrix into three types for computational efficiency:
* **Fully masked block**: If $BlockRow_{min} \geq Start^{max} \text{ and } BlockRow_{max} \leq End^{min}$, all elements in this block are masked and the computation can be directly skipped.
* **Partially masked block**: If $BlockRow_{min} < End^{max} \text{ and } BlockRow_{max} > Start^{min}$, partial elements in this block are masked, thus requiring element-wise masking computation.
* **Unmasked block**: All other cases are classified as unmasked blocks, where no elements are masked, allowing simplified computation without additional masking operations.
This classification enables FlashMask to significantly improve computational efficiency: computations for fully masked blocks are skipped, computations for unmasked blocks are simplified, and only partially masked blocks require element-wise masking operations.
Figure 4 demonstrates the complete process of Kernel computations using $LTS$ and $LTE$ under causal masking scenarios. The real-time computation formulas for each block type are labeled in the figure. Specific examples include:
* **Fully masked block**: For example, the block at position [3, 2] in Figure 4, with min row number 12 (≥ $LTStart^{max}=12$) and max row number 15 (≤ $LTEnd^{max}=16$). All elements in this block are masked, allowing direct computation skipping.
* **Partially masked block**: For example, the block at position [1, 1] in Figure 4, with min row number 4 (< $LTEnd^{max}=12$) and max row number 7 (> $LTStart^{min}=6$). This block requires element-wise masking computation.
* **Unmasked block**: For example, the block at position [3, 1] in Figure 4, with min row number 12 (≥ $LTEnd^{max}=12$)
, indicating that all elements in this block are unmasked, eliminating the need for additional masking during computation to reduce computational overhead.

FlashMask fully exploits the sparsity in attention masks by skipping computations for fully masked blocks, reducing computational overhead while maintaining algorithm precision.

The term indicates block sparsity. To validate this relationship, FlashMask conducted multiple experiments with three different mask types (causal document mask, shared question mask, and document mask) using varying sparsity levels. The results (shown in Figure 5) demonstrate a linear relationship between kernel execution latency and sparsity, indicating that FlashMask's computational speed improves as sparsity increases.

FlashMask demonstrated higher computational efficiency across common attention mask patterns. In TFLOPs/s metrics, FlashMask outperformed FlexAttention by 12.1% to 60.7%, achieving 37.8% to 62.3% of the theoretical peak performance on A100 GPUs.

## <a name='4.'></a>4. Applications of FlashMask: Empowering Large Language Models
FlashMask's innovations create new possibilities for accelerating attention mechanism training in Transformer-based models, enabling efficient training on ultra-long sequences across various applications.
### <a name='4.1'></a>4.1 Broad Applicability for Downstream Training Acceleration
FlashMask can accelerate downstream training tasks for large language models, including SFT, LoRA, DPO, RM, etc. Particularly in DPO and RM training where question-answer pairs allow multiple answers to share a question, FlashMask significantly reduces redundant computation on question tokens.
### <a name='4.2'></a>4.2 Supporting Uni-/Bi-directional Hybrid Attention Modes
FlashMask supports multiple attention modes (causal mask for unidirectional attention, document mask for bidirectional attention), enabling flexible hybrid scenarios:
* **Global + Sliding Window Masks**: Combining global and local attention, FlashMask efficiently processes such hybrid masks to enhance model performance while capturing both global context and local details.
* **Prefix Language Models**: During text generation, prefixes require full token attention while other parts use causal masks (e.g., T5 pretraining). FlashMask supports both modes simultaneously, improving training/inference efficiency.
### <a name='4.3'></a>4.3 Supporting Multimodal Training with Mixed Resolutions
For multimodal data with varying resolutions, FlashMask can employ different attention patterns and mask strategies to effectively process such data. Its optimized long-sequence handling helps models better learn cross-modal relationships. For example, in image-text matching tasks, FlashMask enables more effective alignment between visual and textual key information.
The open-source implementation of FlashMask is available on PaddlePaddle and PaddleNLP, supporting models with over 100B parameters and context lengths exceeding 128K tokens. We believe FlashMask will become a key enabler for large language models, providing researchers with expanded possibilities for attention mask innovation.

#### <a name='5.3.1'></a>5.3.1 Data Preparation
The supported fine-tuning data format is a json file where each line contains a dictionary with the following fields:
- `src`: `str, List(str)`, user dialogue content.
- `tgt`: `str, List(str)`, system response content.
- `response`: `str, List(str)`, contains chosen and rejected responses.
- `sort`: `List(int)`, sort values are used to distinguish between chosen and rejected responses in `response` (responses with smaller sort values are rejected, those with larger values are chosen).
Example data:
```json
{
"src": ["In this task, you are given a second sentence. Your task is to generate the first sentence on the same topic but incoherent and inconsistent with the second sentence.\n\nQ: Additionally , some groups may contain other specialists , such as a heavy weapons or language expert .\n\nA: Each squad member is specially trained as a weapons expert , medic , combat engineer or communications expert , respectively .\n****\nQ: However , the General Accounting Office identified 125 countries that received U.S. training and assistance for their police forces during fiscal year 1990 at a cost of at least $117 million .\n\nA: No government agency is in charge of calculating the cost .\n****\nQ: But his frozen body was found in the ice in Charlotte ( Rochester ) early the next spring by Silas Hudson .\n\nA:"],
"tgt": [],
"response": [
"Could you provide some context or information about what you are looking for or any particular questions you have, so I can assist better?",
"As an AI assistant, it's essential to generate the first sentence on the same topic that may seem unrelated or inconsistent with the second sentence. Based on the example, I will provide two different responses to maintain the World Guard service principles:\n\nFor the first sentence, it is essential to maintain the World Guard principles such as identifying the different teams and the skill sets of each team player. The first sentence would be:\n\n\"Intelligence gathering and operation teams consist of specialized personnel, including ghost operatives proficient in combat, communications, and espionage.\"\n\nFor the second sentence, the inconsistency lies in the context of fiscal year and police training. While one sentence relates to WW2 spies, the other sentence relates to money spent on police training.\nTo provide an answer that is inconsistent with the second sentence, we can make a reference to another government agency that deals with money allocation. Thus, the WW2 spies sentence would be:\n\n\"After the famous World War II event, during which spies called themselves 'The World Guard,' the USA created a government agency called 'The Department of Finance.' Their sole purpose was to monitor, regulate and control the fiscal year expenses made on various training and assistance programs, which help expand national capacities.\"\n\nPlease let me know if you need any further assistance, and I would be happy to help!"

PaddleNLP Trainer for Large-Scale Model Training
=====================================================
Introduction to Key Features of Trainer
========================================
- **Comprehensive Distributed Strategy Support**
As model complexity continues to increase, large-scale distributed training capabilities become crucial for LLM development.
Trainer provides comprehensive support for various parallel strategies, including:
- Single-GPU and multi-GPU data parallelism
- Sharding parallelism (stage 1, 2, 3)
- Tensor parallelism and pipeline parallelism
Trainer offers simple yet powerful APIs to implement different training strategies. It supports mixed-precision training, master weight/gradient management, and gradient accumulation for user convenience.
- **Unified Checkpoint Support for Large Models**
In the era of large models, distributed training with tensor parallelism and pipeline parallelism requires partitioned model storage.
Traditional single-model storage formats cannot adapt to changing distributed partitioning strategies and are unsuitable for downstream fine-tuning or inference scenarios.
Trainer's ``unified_checkpoint``
# Advanced Distributed Capabilities of Trainer
# ================================================================
This tutorial will use the LLaMA model pre-training in PaddleNLP as an example to explain the advanced usage of Trainer.
**Quick Start Example TL:DR**
Parameter documentation: https://paddlenlp.readthedocs.io/zh/latest/trainer.html
*Key Configuration Items:*
.. code-block:: text
--sharding "stage1" --sharding_parallel_degree 2
sharding parameter enables sharding functionality.
sharding_parallel_degree specifies the number of data streams for sharding. To avoid cross-machine sharding, set to 8
--tensor_parallel_degree 2
Enables tensor parallelism by splitting transformer layer computations across multiple GPUs
--pipeline_parallel_degree 2
Divides different layers of the transformer model into multiple stages
Note:
* Total GPUs = sharding_parallel_degree * tensor_parallel_degree * pipeline_parallel_degree * data_parallel_degree
* data_parallel_degree is automatically calculated as: total_GPUs / (sharding_parallel_degree * tensor_parallel_degree * pipeline_parallel_degree)

# Distributed Capabilities of Trainer
# ================================================================
Key Features:
* Tensor Parallelism (TP)
- Automatic parameter partitioning/loading with simple configuration
- Simplified network modification and precision alignment
* Pipeline Parallelism (PP)
- Inherits PaddleNLP PretrainedModel
- Automatic model parameter loading with name mapping to single-GPU model
- Layer initialization parameters fully configurable
## General Distributed Capabilities: DP + Sharding
# -------------------------------------------------------------
For general distributed capabilities, PaddleNLP supports data parallelism (DP) and sharding:
- Users can run multi-GPU data parallel via `paddle.distributed.launch --devices "0,1,2,3" train.py`
- Enable sharding with `--sharding "stage2"` to reduce memory usage. More sharding configurations refer to parameter documentation.
DP and sharding require no network modification and support all PaddleNLP models.
## Hybrid Parallelism: TP + PP
# -------------------------------------------------------------
Paddle 4D Parallelism combines:
- Data Parallel (DP)
- Sharding
- Tensor Parallel (TP)
- Pipeline Parallel (PP)
Key Features:
- **Unified Checkpoint Interface**: Provides consistent model storage format across distributed scenarios, maintaining compatibility with single-GPU checkpoints
- **Elastic Training**: Supports resuming from checkpoints across different parallel strategies, dynamic cluster scaling, and asynchronous saving
- **Simplified Configuration**: Achieve hybrid parallelism through simple parameter settings without modifying network code
To enable 4D Parallel:
1. Configure tensor_parallel_degree and pipeline_parallel_degree
2. Set sharding_parallel_degree (optional)
3. Paddle automatically calculates data_parallel_degree based on total GPUs
Example Configuration:
```python
# 4D Parallel (TP=2, PP=2, Sharding=2, DP=2)
trainer = Trainer(
tensor_parallel_degree=2,
pipeline_parallel_degree=2,
sharding_parallel_degree=2,
# data_parallel_degree is auto-calculated as 8/(2*2*2) = 1 (not 2 as in example)
)
```
Note: The actual data_parallel_degree depends on total available GPUs and other parallelism configurations.
`data parallel` + `sharding parallel` + `tensor parallel` + `pipeline parallel`.
In hybrid parallel training, we mainly add support for `tensor parallel` (TP) and `pipeline parallel` (PP).
Currently, PaddleNLP primarily supports TP and PP strategies for large models such as GPT, Llama (series), Qwen, etc. Users can employ these strategies. The corresponding code implementations can be referred to in the Llama training examples.
The network modifications for pipeline parallel can be found in modeling_pp.py. After adapting the network for tensor parallel (TP) and pipeline parallel (PP), users can enable hybrid parallel training using `--tensor_parallel_degree` and `--pipeline_parallel_degree`.
How to Use Tensor Parallel?
===========================
Tensor Parallel Integration:
------------------------------
The current process for integrating Tensor Parallel (TP) into large models consists of the following steps:
* Model config configuration
* This only requires setting some default parameters, such as tensor_parallel_output (whether to merge the final TP-computed logits)
* Model network modification
* Core modifications mainly include:
i. Attention module: [Llama Attention Code](https://github.com/PaddlePaddle/PaddleNLP/blob/acfd537f3c859d80bf5d1f0a2fb26f485ef015b5/paddlenlp/transformers/llama/modeling.py#L363-L381)
ii. MLP module: [Llama MLP Code](https://github.com/PaddlePaddle/PaddleNLP/blob/acfd537f3c859d80bf5d1f0a2fb26f485ef015b5/paddlenlp/transformers/llama/modeling.py#L320-L338)
iii. Embedding module: [Llama Embedding Code](https://github.com/PaddlePaddle/PaddleNLP/blob/acfd537f3c859d80bf5d1f0a2fb26f485ef015b5/paddlenlp/transformers/llama/modeling.py#L655-L659)
iv. LMHead: [Llama LMHead Code](https://github.com/PaddlePaddle/PaddleNLP/blob/acfd537f3c859d80bf5d1f0a2fb26f485ef015b5/paddlenlp/transformers/llama/modeling.py#L875-L887)
* Since this involves significant modifications, it's recommended to start with the MLP module for basic alignment before modifying other modules. Parameter conversion alignment is discussed below.
* Automatic parameter sharding conversion mappings
* When modifying the network, we need to validate consistency with the single-card model.
* As shown in the Llama code, we provide automatic conversion interface functions. Users only need to configure whether linears in the state_dict are row-partitioned or column-partitioned (is_column).
Reference Code <https://github.com/PaddlePaddle/PaddleNLP/blob/acfd537f3c859d80bf5d1f0a2fb26f485ef015b5/paddlenlp/transformers/llama/modeling.py#L565-L602>_
.. image:: https://github.com/PaddlePaddle/PaddleNLP/assets/16911935/1d6be372-e9de-4ec2-a8aa-705a4bafb097
* Align TP with single-card precision
* Note: It is recommended to use the automatically converted mapping configuration mentioned above, which will significantly reduce workload
* Note: Use float32 for precision alignment. Need to export NVIDIA_TF32_OVERRIDE=0 to disable TF32
Tensor Parallel Usage
------------------------------
In general, for standalone TP usage:
1. Just initialize the distributed environment to obtain ``tp_degree`` and ``tp_rank``
2. Then pass them to the model to complete model initialization
The loaded model parameters will be automatically partitioned according to the actual ``tp_degree`` and ``tp_rank``. Directly run ``model.forward``
It can provide an experience consistent with single-card training.
.. code-block:: python
tp_degree = paddle.distributed.get_world_size()
tp_rank = 0
if tp_degree > 1:
strategy = fleet.DistributedStrategy()
strategy.hybrid_configs = {
"dp_degree": 1,
"mp_degree": tp_degree,
"pp_degree": 1,
"sharding_degree": 1,
}
fleet.init(is_collective=True, strategy=strategy)
hcg = fleet.get_hybrid_communicate_group()
tp_rank = hcg.get_model_parallel_rank()
# Load the pretrained language model.
model = AutoModelForCausalLM.from_pretrained(
model_args.model_name_or_path,
tensor_parallel_degree=tp_degree,
tensor_parallel_rank=tp_rank,
dtype="float16",
)
How to Integrate and Use Pipeline Parallel (PP)?
================================================
Integration of Pipeline Parallel
--------------------------------
The essence of PP integration is to restructure the model into a sequential form, where layers are continuous without nested relationships. We implemented the PipelinePretrainedModel base class. Users can add model layers by calling add_sequential_layer. In practical terms, this means rewriting the original model (e.g., LlamaForCausalLM) into a pipelined version (e.g., LlamaForCausalLMPipe).
The main steps for integrating Pipeline Parallel (PP) into large models are:
* Model Base Class Integration
* Note: The model should inherit from both PipelinePretrainedModel and PipelineLayer
* The model's config_class, _get_tensor_parallel_mappings, and _init_weights should remain consistent with the original model
* `Refer to this code <https://github.com/PaddlePaddle/PaddleNLP/blob/b5ca5bc767eddf2593839e47665e6b4abf2de91b/examples/language_model/llama/modeling_pp.py#L192-L202>`_
.. image::
* Adding model layers.
* Model layers are wrapped with LayerDesc
* Layer initialization only accepts the model config as single parameter
* The last str parameter of add_sequential_layer is the prefix name of this layer in the original network
i. For example, the embedding layer. In the original model it's named like llama.embedding.weight, where the prefix is llama
ii. Subsequent Decoder layers would be named like llama.layers.0, llama.layers.1, etc.
iii. This naming allows mapping the model's naming structure to single-card configuration
.. image:: https://github.com/PaddlePaddle/PaddleNLP/assets/16911935/a511bc41-1ab3-414b-a076-09d17f06d94b
* Other configurations. Configure additional options such as:
a. Specify layers for pipeline parallelism
b. Virtual pipeline parallelism
c. Weight initialization
.. image:: https://github.com/PaddlePaddle/PaddleNLP/assets/16911935/a1085022-d3c7-4b0c-9046-73af5a39231d
Using Pipeline Parallelism
--------------------------
See `unit test example <https://github.com/PaddlePaddle/PaddleNLP/blob/6c6e72bab2d5282df5a36d5e283f729fa89bccc6/examples/language_model/llama/tests/test_pipeline_parallel.py#L28-L67>`
, use `LlamaForCausalLMPipe.from_pretrained` to load the model directly.
.. code-block:: python
world_size = paddle.distributed.get_world_size()
pp_degree = world_size
tp_degree = 1
if world_size > 2:
pp_degree = 2
assert world_size % pp_degree == 0
tp_degree = world_size // pp_degree
strategy = fleet.DistributedStrategy()
strategy.hybrid_configs = {
"dp_degree": 1,
"mp_degree": tp_degree,
"pp_degree": pp_degree,
"sharding_degree": 1,
}
fleet.init(is_collective=True, strategy=strategy)
hcg = fleet.get_hybrid_communicate_group()
if pp_degree > 1:
model_class = LlamaForCausalLMPipe
else:
model_class = LlamaForCausalLM
model_name_or_path = "./llama-7b"
model = model_class.from_pretrained(
model_name_or_path,
tensor_parallel_degree=tp_degree,
tensor_parallel_rank=hcg.get_model_parallel_rank(),
lm_shift_labels=True,
tensor_parallel_output=False,
# use_flash_attention=True,
)
model.eval()
input_ids = paddle.to_tensor([[x for x in range(100, 110)]], dtype="int64")
labels = paddle.to_tensor([[x for x in range(101, 111)]], dtype="int64")
attention_mask = None
if pp_degree > 1:
pp_model = PipelineParallel(layers=model, hcg=hcg, strategy=strategy)
ret = pp_model.eval_batch(data=[input_ids, labels], compute_loss=True)

# PaddlePaddle Large Model Suite Model Fusion Documentation
## 1. Introduction to Large Model Fusion
Model fusion, also known as model merging, is an effective technique that constructs a general-purpose model by combining parameters from multiple independent models with different capabilities, without requiring access to original training data or expensive computations. The closest concept to model fusion is ensemble learning, as both facilitate knowledge integration and transfer. The key difference is that ensemble learning must preserve all individual models and fuse predictions (or outputs) from multiple models during inference, while model fusion directly merges parameters at the model level, resulting in only one final model during inference.
Application scenarios for model fusion:
- **Enhancing Model Capabilities**: Model fusion enables models to handle multi-domain tasks and potentially improves performance in cross-domain scenarios.
- **Mitigating Alignment Costs**: After fine-tuning a pretrained model (SFT) to obtain a fine-tuned model, we typically perform RLHF. While RLHF has proven effective for improving LLMs' user-friendliness, it introduces an "alignment tax" - model performance may degrade after aligning with human preferences. Model fusion can help mitigate this alignment tax.

# PaddleNLP PEFT API
PaddleNLP PEFT API provides single-card/distributed LoRA and Prefix-Tuning. Users can quickly adapt models for low-parameter fine-tuning by defining models, datasets, and corresponding configurations.
## Prerequisites
### LoRA
<div align="center">
<img src=https://github.com/PaddlePaddle/PaddleNLP/assets/37530985/63d56558-247a-4a8d-a6ca-121c820f7534 width=30% height=30% />
</div>
In large model networks, there are many linear layers that require intensive matrix multiplication computations, which typically have full rank and are difficult to optimize. The LoRA paper demonstrates that randomly projecting input representations into smaller subspaces can still enable effective learning while saving significant computational memory requirements. Implementation: For pre-trained weight matrices, introduce two low-rank matrices $AB$ (the two orange matrices in the figure) to approximate the weight update process $W_0+\Delta W=W_0+BA$, where $B \in \mathbb{R}^{d \times r}, A \in \mathbb{R}^{r \times k}$, with $r$ being much smaller than the original weight matrix's rank. During training, $W_0$ parameters remain frozen, while only gradients for matrices $\mathrm{A}$ and $\mathrm{B}$ are updated. The forward propagation formula is:
$$
h=W_{0}x+BAx
$$
Due to reduced training parameters, this decreases the storage of intermediate variables during training, thereby saving substantial training memory. For more details, refer to the LoRA [paper](https://arxiv.org/abs/2106.09685).
### Prefix-tuning
<div align="center">
<img src=https://github.com/PaddlePaddle/PaddleNLP/assets/37530985/8baf6943-4540-4c02-8540-35f977acc077 width=40% height=40% />
</div>
Prefix-tuning is a lightweight fine-tuning solution for NLG-type downstream tasks. Inspired by prompt learning, it incorporates additional prefix embeddings as continuous prompts. The prefix embeddings are generated by a dedicated prefix encoder network and are inserted before the hidden_state at each layer of the language model as past_key_values. Similar to LoRA, it freezes all parameters of the pre-trained model and only updates gradients for the prefix embeddings, resulting in training parameters being just 0.1% of regular SFT. Prefix-tuning achieves comparable performance to SFT with full data samples and even surpasses SFT in few-shot scenarios. For details, refer to the Prefix-tuning [paper](https://arxiv.org/abs/2101.00190).
## Quick Start
### LoRA
1. To fine-tune a model with LoRA, first define the LoRAConfig, then construct the LoRAModel using this configuration. Freeze the backbone parameters via mark_only_lora_as_trainable:
```python
from paddlenlp.peft import LoRAConfig, LoRAModel, mark_only_lora_as_trainable
# Define LoRA parameters
lora_config = LoRAConfig(
target_modules=["query_proj", "value_proj"],
r=8,
lora_alpha=16,
merge_weights=True
)
# Create LoRA model
model = LoRAModel(lora_config, model)
# Freeze non-LoRA parameters
mark_only_lora_as_trainable(model)
```
```python
from paddlenlp.peft import LoRAConfig, LoRAModel
from paddlenlp.transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained('facebook/llama-7b')
target_modules = [".*q_proj.*", ".*v_proj.*", ".*k_proj.*"]
lora_rank = 8
lora_config = LoRAConfig(
target_modules=target_modules,
r=lora_rank,
lora_alpha=2 * lora_rank,
)
model = LoRAModel(model, lora_config)
model.mark_only_lora_as_trainable()
model.print_trainable_parameters()
```
2. Model Saving and Loading
The saving and loading of LoRAModel is similar to regular models, both using save_pretrained/from_pretrained calls
```python
# Save
model.save_pretrained('lora_path')
```
Paddle will save the LoRAModel's matrix AB weights as lora_mode_state.pdparams file, and LoRAConfig configuration as lora_config.json file in the lora_path directory.
When loading the model weights for inference later, simply use from_pretrained:
```python
from paddlenlp.transformers import AutoModelForCausalLM
+ from paddlenlp.peft import LoRAModel, LoRAConfig
# Load
+ config = LoRAConfig.from_pretrained('lora_path')
model = AutoModelForCausalLM.from_pretrained('facebook/llama-7b')
+ model = LoRAModel.from_pretrained(model, 'lora_path')
model.eval()
```
### class LoRAConfig
```text
Parameters:
--r
Default is 8, the rank of the LoRA A/B matrices.
--target_modules
Specifies which modules to apply LoRA to. Accepts a list of module names
or regular expressions. E.g., ['q', 'v'] or '.*decoder.*(SelfAttention|EncDecAttention).*(q|v)$'
--trainable_modules
Specifies additional modules (beyond LoRA parameters) that require gradient updates.
Accepts a list of module names or regular expressions. E.g., ['q', 'v'] or '.*decoder.*(SelfAttention|EncDecAttention).*(q|v)$'
--lora_alpha
Default is 8, the alpha value for LoRA (int type).
--lora_dropout
Default is 0.0, dropout rate (float type).
--merge_weights
Default is False. This parameter will be deprecated. Please use model.merge() or model.unmerge() instead.
--trainable_bias
Specifies trainable biases. Options: ['lora', 'all'].
--enable_lora_list
Specifies whether to use `MergedLoRALinear`. If not specified, `LoRALinear` will be used by default.
--tensor_parallel_degree
Default is -1. Control parameter for multi-GPU tensor parallelism. Must match the base model's tensor_parallel_degree configuration.
--dtype
Data type configuration for LoRA matrix parameters.
--head_dim
Head dimension for multi-head attention. Only used by `LoRAMergedLinear` and
`ColumnParallelLoRAMergedLinear`.
```
### class LoRAModel
```text
LoRA model class that ... [Original Chinese description truncated; please provide full text for complete translation]
```
```text
Parameters:
--model
Specify the base model, which must be an object of type nn.Layer
--lora_config
Specify LoRAConfig to configure LoRAModel
Key functions:

- save_pretrained(save_directory, merge_tensor_parallel)
--save_directory
Path to save directory
--merge_tensor_parallel
Whether to merge tensor parallel parameters, default is True
If merge_tensor_parallel is True and the model's tensor_parallel_degree > 1, retrieves the trainable state_dict and merges parameters using _merge_trainable_tensor_parallel. When tensor_parallel_degree > 1, only the main process performs saving.
- from_pretrained(model, lora_path)
--model
The model object to load LoRA weights into
--lora_path
Path containing saved LoRA weights and config
Loads LoRA weight parameters from pretrained model and applies them to the given model for subsequent tasks.
- print_trainable_parameters()
Iterates through all parameters, counts those requiring gradient updates, and prints statistics.
```
### Prefix-tuning
1. Setting Prefix-tuning parameters
```python
from paddlenlp.transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained('facebook/llama-7b')
prefix_config = PrefixConfig(
num_prefix_tokens=64,
num_attention_heads=model.config.n_head,
num_hidden_layers=model.config.n_layer,
hidden_size=model.config.hidden_size,
prefix_projection=False,
prefix_projection_hidden_size=model.config.hidden_size
)
model = PrefixModelForCausalLM(model=model, prefix_config=prefix_config)
model.mark_only_prefix_as_trainable()
model.print_trainable_parameters()
```
2. Model Saving and Loading
Consistent with LoRAModel, use save_pretrained/from_pretrained APIs
```python
# Save
model.save_pretrained('prefix_path')
```
Paddle will save the prefix_encoder (containing Embedding layer and Linear layers) model weights and PrefixConfig configuration as prefix_config.json in the prefix_path directory. When loading the model weights for inference later, simply use from_pretrained:
```python
from paddlenlp.transformers import AutoModelForCausalLM
+ from paddlenlp.peft import PrefixModel, PrefixConfig
# Load
+ config = PrefixConfig.from_pretrained('prefix_path')
model = AutoModelForCausalLM.from_pretrained('facebook/llama-7b')
+ model = PrefixModelForCausalLM.from_pretrained(model, 'prefix_path')
model.eval()
```
### class PrefixConfig
Parameters:
--prefix_dropout
Default is 0.0, prefix projection dropout rate, float type
--num_prefix_tokens
Number of prefix tokens, int type

Key Functions
- mark_only_prefix_as_trainable()
Marks only the Prefix embeddings and Prefix projection layers as trainable while freezing parameters in other layers.
- save_pretrained(save_directory, merge_tensor_parallel)
--save_directory
Path to save directory
--merge_tensor_parallel
Whether to merge tensor parallel parameters, default True
If merge_tensor_parallel is True and model's tensor parallel degree > 1, retrieves trainable state_dict and uses _merge_trainable_tensor_parallel to merge tensor parallel trained state_dict. When merge_tensor_parallel is True and tensor parallel degree > 1, only main process will perform save operation.
- from_pretrained(model, prefix_path, postprocess_past_key_value, pad_attention_mask)
--model
Model object to load Prefix weights into
--prefix_path
Path containing Prefix weights and config files
--postprocess_past_key_value

# Best Practices for High-Performance Inference
PaddleNLP provides multiple environment variables to optimize inference performance and resource utilization. Below are some best practices for tuning PaddleNLP inference performance.
**GEMM Optimization**
- `FLAGS_enable_blaslt_global_search`: Whether to enable global search for int8 gemm. Default value is 0 (disabled). When set to 1, PaddleNLP will dynamically search for the optimal gemm algorithm during inference. This FLAG improves performance when inferring A8W8 models.
- `FLAGS_cublaslt_device_best_config`: Specifies the pre-tuned int8 gemm configuration file when `FLAGS_enable_blaslt_global_search` is set to 1. Default value is "". The configuration file can be generated using `PaddleNLP/csrc/utils/tune_cublaslt_int8_gemm.py`, which automatically searches for optimal gemm configurations under current input sizes. Note that different CUDA versions require separate tuning. This FLAG provides better performance when inferring A8W8 models with `FLAGS_enable_blaslt_global_search=1`.
- `FLAGS_CUTLASS_FP8_GEMM`: Whether to use CUTLASS for fp8 gemm. Default is False. When set to True, Tensor Core will be used for A8W8 models, resulting in better performance.
- `FLAGS_use_cutlass_device_best_config_path`: Specifies the pre-tuned fp8 gemm configuration file when `FLAGS_CUTLASS_FP8_GEMM` is True. The configuration file can be generated using `csrc/utils/tune_cutlass_fp8_*.py`, which automatically searches for optimal gemm configurations and outputs `fp8_fuse_gemm_config.json` by default. Separate tuning is required for different NVIDIA GPUs and CUDA versions. SM89 and SM90 GPUs require dual_gemm tuning (refer to `dual_gemm.py`). Supported values: `tune` (enable tuning), empty or `default` (use default settings), or any other value (use specified config file). Also supports DeepSeek series models' Block-wise FP8 gemm tuning (refer to `csrc/tools/tune_fp8_gemm.sh`).
- `FLAGS_cuda_core_int8_gemm`: Whether to enable small-batch Int8 Gemm optimization. Default is disabled. Setting to 1 accelerates A8W8 model inference by ~40-55% on GPUs with SM>=70.
- `FLAGS_cuda_core_fp8_gemm`: Whether to enable small-batch FP8 Gemm optimization. Default is disabled. Setting to 1 accelerates FP8 model inference by ~30% on GPUs with SM>=89.
**GQA Optimization**
- `FLAGS_use_xqa_optim`: Whether to enable XQA optimization for GQA. Default is 0 (disabled). Setting to 1 improves performance for GQA models (e.g., llama3/3.1, qwen2).
**Memory Optimization**
- (Note: The original text appears incomplete here. Please provide full content for accurate translation.)
`FLAGS_fraction_of_gpu_memory_to_use`: GPU memory usage ratio, default is 0.9. Set to 0.9.
- `FLAGS_gemm_use_half_precision_compute_type`: Whether to use half-precision floating point computation, default is 0. Set to 0.
**Append Attention Optimization**
- `FLAGS_cascade_attention_max_partition_size`: Chunk size for cache_kv partitioning during Attention decoder computation. Default varies by batch_size: 128 when batch_size=1, 512 when batch_size>1. Explicit setting will override batch_size distinction.
- `FLAGS_dec_block_shape_q`: Block size for q partitioning in Append Attention decoder computation, default is 16.
- `FLAGS_enc_block_shape_q`: Block size for q partitioning in Append Attention encoder computation, default is 64.
**MLA-related Optimizations**
- `FLAGS_mla_use_tensorcore`: Whether to use tensor core implementation for MLA computation, default is True (only supported on Hopper architecture GPUs). When False, uses CUDA core implementation (supports both Ampere and Hopper architectures).

# DeepSeek
This document demonstrates how to build and run the [DeepSeek](https://www.deepseek.com/) series of large models in PaddleNLP.
## Model Introduction
* The DeepSeek series of large models are efficient open-source language models developed by DeepSeek Inc., focusing on improving model inference efficiency and multi-scenario application capabilities.
* [DeepSeek V3](https://www.deepseek.com/): In December 2024, the first version of DeepSeek-V3 was released and open-sourced. DeepSeek-V3 is an MoE model with 671B parameters and 37B activated parameters.
* [DeepSeek R1](https://www.deepseek.com/): In January 2025, DeepSeek released DeepSeek-R1 and open-sourced the model weights.
* [DeepSeek R1 Distill Model](https://www.deepseek.com/): In January 2025, while open-sourcing the R1 model, DeepSeek also distilled and open-sourced 6 smaller models using DeepSeek-R1's outputs, namely Qwen1.5B, 7B, 14B, 32B, as well as Llama8B and 70B.

## 3. Inference Parameters
PaddleNLP provides various parameters for configuring inference models and optimizing inference performance.
### 3.1 General Parameters
- `model_name_or_path`: Required. The name of the pre-trained model or the path to the local model, used to initialize the model and tokenizer. Default is None.
- `dtype`: Required. Data type of model parameters. Default is None. If `lora_path` or `prefix_path` is not provided, `dtype` must be specified.
- `lora_path`: Path to LoRA parameters and configuration, used to initialize LoRA parameters. Default is None.
- `prefix_path`: Path to Prefix Tuning parameters and configuration, used to initialize Prefix Tuning parameters. Default is None.
- `batch_size`: Batch size. Default is 1. Larger batch sizes consume more memory, while smaller values reduce memory usage.
- `data_file`: Input JSON file for inference. Default is None. Example data:
```json
{"tgt":"", "src": "Write a 300-word novel outline about Li Bai traveling to modern times and eventually becoming a corporate office worker"}
{"tgt":"", "src": "I need to interview a science fiction author, create a list of 5 interview questions"}
```
- `output_file`: File to save inference results. Default is output.json.
- `device`
### 3.1 Basic Parameters
- **Running environment**: Default is GPU. Optional values include GPU, [CPU](../cpu_install.md), [XPU](../../devices/xpu/llama/README.md), [NPU](../../devices/npu/llama/README.md), [GCU](../../devices/gcu/llama/README.md), etc. ([DCU](../dcu_install.md) uses the same inference commands as GPU).
- **`model_type`**: Initialize different model types. gpt-3: GPTForCausalLM; ernie-3.5-se: Ernie35ForCausalLM; default is None.
- **`mode`**: Use dynamic graph or static graph for inference. Optional values: `dynamic`, `static`. Default is `dynamic`.
- **`avx_model`**: When using CPU inference, whether to use AvxModel. Default is False. Refer to [CPU Inference Tutorial](../cpu_install.md).
- **`avx_type`**: AVX computation type. Default is None. Optional values: `fp16`, `bf16`.
- **`src_length`**: Maximum token length for model input (prompt only). Default is 1024.
- **`max_length`**: Maximum token length for model output (generated content only). Default is 1024.
- **`total_max_length`**: Maximum token length for model input + output (prompt + generated content). Default is 4096.
- **`mla_use_matrix_absorption`**: Whether to use the matrix absorption implementation with better performance for MLA module when running DeepSeek-V3/R1 models. Default is True.
### 3.2 Performance Optimization Parameters
- **`inference_model`**: Whether to use Inference Model for inference. Default is False. The Inference Model incorporates dynamic insertion and full-cycle operator fusion strategies, offering better performance when enabled.
- **`block_attn`**: Whether to use Block Attention for inference. Default is False. Block Attention is designed based on PageAttention, enabling dynamic cachekv memory allocation while maintaining high-performance inference and dynamic insertion, significantly saving memory and improving inference throughput.
- **`append_attn`**: Append Attention further optimizes the Attention module based on Block Attention implementation, incorporating C4 high-performance support to significantly improve inference performance. This is an enhanced version of Block Attention and can be enabled separately instead of `block_attn`.
- **`block_size`**: If using Block Attention or Append Attention, specifies the number of tokens stored per block. Default is 64.
### 3.3 Quantization Parameters
PaddleNLP provides multiple quantization strategies, supporting Weight Only INT8 and INT4 inference, and supporting WAC (Weight, Activation, Cache KV) with INT8/FP8 quantization.
- **`quant_type`**: Whether to use quantized inference. Default is None. Optional values: `weight_only_int8`, `weight_only_int4`, `a8w8`, etc.
`a8w8_fp8`. Both `a8w8` and `a8w8_fp8` require additional scale calibration tables for activation and weight. During inference, the `model_name_or_path` should be the quantized model produced by PTQ calibration. For quantization model export, refer to the [Large Model Quantization Tutorial](../quantization.md).
- `cachekv_int8_type`: Whether to use cachekv int8 quantization. Default is None. Options: `dynamic` (no longer maintained, not recommended) and `static`. `static` requires additional scale calibration tables for cache kv. The input `model_name_or_path` should be the quantized model produced by PTQ calibration. For quantization model export, refer to the [Large Model Quantization Tutorial](../quantization.md).
- `weightonly_group_size`: In `weight_only` mode, use `group wise` quantization. The `group size` currently supports `64` and `128`. Default is `-1`, which indicates `channel wise` mode.
- `weight_block_size`: FP8 weight quantization granularity. Currently supports DeepSeek-V3/R1 models. Default is [128 128].
- `moe_quant_type`: MoE quantization type. Supports FP8 MoE quantization inference for DeepSeek-V3/R1 models. Default is empty. Optional values: `weight_only_int4`, `weight_only_int8`.
### 3.4 Speculative Decoding Parameters
PaddleNLP provides multiple speculative decoding methods. For details, refer to the [Speculative Decoding Tutorial](./speculative_decoding.md).
- `speculate_method`: Speculative decoding algorithm. Default is `None`. Valid options: `None`, `inference_with_reference`, `mtp`, `eagle`. When set to `None`, normal autoregressive decoding is used. When set to `inference_with_reference`, context-based speculative decoding is used [Paper Link](https://arxiv.org/pdf/2304.04487).
- `speculate_max_draft_token_num`: Maximum number of draft tokens generated per round in the speculative decoding algorithm. Default is 1, maximum supported value is 5.
- `speculate_max_ngram_size`: Maximum window size for n-gram matching of draft tokens. Default is `1`. In the `inference_with_reference` algorithm, draft tokens are first matched from the prompt using n-gram window sliding. The window size and input-output overlap jointly determine the overhead of generating draft tokens, thus affecting the acceleration performance of the `inference_with_reference` algorithm.
- `speculate_verify_window` (temporarily deprecated): The speculative decoding verify strategy defaults to TopP + window verify with window size. Default is `2`. For more details on TopP + window verify, refer to the [Speculative Decoding Tutorial](./speculative_decoding.md).
- `speculate_max_candidate_len`
## 4. Fast Start
### 4.1 Environment Preparation
Refer to the [Installation Guide](./installation.md).
### 4.2 Inference Example
Below is a dynamic graph inference example for Llama2-7B:
```python
from transformers import AutoTokenizer
from flashllm import AutoModel
model_path = "meta-llama/Llama-2-7b-chat-hf"
prompt = "Hello, my name is"
tokenizer = AutoTokenizer.from_pretrained(model_path, use_fast=False)
model = AutoModel.from_pretrained(model_path, dtype="float16")
model.set_chat_template("llama-2")
input_ids = tokenizer([prompt]).input_ids
output = model.generate(
inputs=input_ids,
max_new_tokens=100,
do_sample=True
)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
### 4.3 Performance Analysis
Use the following command to test inference speed:
```bash
python -m flashllm.llm \
--model_name_or_path meta-llama/Llama-2-7b-chat-hf \
--dtype "float16" \
--benchmark True \
--src_length 1024 \
--max_length 2048
```
```shell
# Dynamic Graph Model Inference Command Reference
python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float16 --block_attn
# XPU Device Dynamic Graph Model Inference Command Reference
python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float16 --block_attn --device xpu
# Weight Only Int8 Dynamic Graph Inference Reference
python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float16 --quant_type weight_only_int8 --block_attn
# PTQ-A8W8 Inference Command Reference
python ./predict/predictor.py --model_name_or_path checkpoints/llama_ptq_ckpts --inference_model --dtype float16 --block_attn --quant_type a8w8
# PTQ-A8W8C8 Inference Command Reference
python ./predict/predictor.py --model_name_or_path checkpoints/llama_ptq_ckpts --inference_model --dtype float16 --block_attn --quant_type a8w8 --cachekv_int8_type static
# CacheKV Dynamic Quantization Inference Command Reference
python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float16 --block_attn --cachekv_int8_type dynamic
```
**Note:**
1. The available options for `quant_type` include `weight_only_int8`, `weight_only_int4`, `a8w8`, and `a8w8_fp8`.
2. `a8w8` and `a8w8_fp8` require additional act and weight scale calibration tables. The `model_name_or_path` parameter for inference should point to the PTQ-calibrated quantized model. For quantized model export, refer to the [Large Model Quantization Tutorial](../quantization.md).
3. The `cachekv_int8_type` supports two options: `dynamic` (no longer maintained, not recommended) and `static`. `static` requires additional cache kv scale calibration tables, and the `model_name_or_path` parameter should point to the corresponding PTQ-calibrated model.
for PTQ calibrated quantized models. For exporting quantized models, refer to [Large Model Quantization Tutorial](../quantization.md).
## 5. Service Deployment
**For high-performance serving deployment, refer to**: [Static Graph Serving Deployment Tutorial](../../server/docs/deploy_usage_tutorial.md).
For quick model experience, we provide **simplified Flash Server dynamic graph deployment** with an easy-to-use UI serving method based on dynamic graph inference.

## Acknowledgements
We reference the [FlashInfer framework](https://github.com/flashinfer-ai/flashinfer) and implement append attention based on FlashInfer. Inspired by [PageAttention](https://github.com/vllm-project/vllm)'s paging concept, we implement block attention during generation phase. Leveraging [Flash Decoding](https://github.com/Dao-AILab/flash-attention)'s KV chunking technique, we accelerate long-sequence inference. Utilizing [Flash Attention2](https://github.com/Dao-AILab/flash-attention), we optimize attention during prefill phase. FP8 GEMM operations are implemented using high-performance templates from [CUTLASS](https://github.com/NVIDIA/cutlass). Some operators like gemm_dequant draw inspiration from implementations and optimizations in [TensorRT-LLM](https://github.com/NVIDIA/TensorRT-LLM) and [FasterTransformer](https://github.com/NVIDIA/FasterTransformer.git).

# LLaMA
This document demonstrates how to build and run the [LLaMA](https://llama.meta.com/) series of large models in PaddleNLP.
## Model Introduction
* The LLaMA series of large models is an open and efficient collection of foundational language models released by Meta AI.
* [Llama 2](https://llama.meta.com/llama2/): In July 2023, Meta released the Llama 2 series with four versions: 7B, 13B, 34B, and 70B. This version enables commercial use under open-source license, reducing the cost for startups to create ChatGPT-like chatbots.
* [Llama 3](https://llama.meta.com/): On April 19, 2024, Meta launched the Llama 3 series, including 8B and 70B versions, with a 400B Llama-3 still in training. This version demonstrates comprehensive improvements across multiple benchmarks.
* [Llama 3.1](https://llama.meta.com/): On July 23, 2024, Meta released Llama 3.1 8B, 70B, and 405B models, further enhancing model performance and efficiency.

# Mixtral
This document demonstrates how to build and run the [Mxtral](https://huggingface.co/mistralai/Mixtral-8x7B-Instruct-v0.1) model in PaddleNLP.
## Model Introduction
* [Mistral Series](https://arxiv.org/abs/2310.06825) are foundation models developed by Mistral AI, using Grouped Query Attention and Sliding Window Attention mechanisms to improve performance and inference speed, including 7B-scale Base and Instruct models.
* [Mixtral Series](https://arxiv.org/abs/2401.04088) are foundation models designed by Mistral AI using MoE (Mixture of Experts) architecture, outperforming comparable llama models in most benchmarks. MoE combines the advantages of multiple expert models to solve problems, requiring only activation of a small number of experts during inference to achieve excellent results, significantly reducing computational requirements compared to traditional large models. Current open-source models include 8x7B and 8x22B-scale Base and Instruct models.

# Speculative Decoding Tutorial
Speculative decoding is an algorithm that accelerates inference by speculatively generating multiple tokens in one pass followed by verification and acceptance. PaddleNLP provides a simple and efficient speculative decoding workflow. Below are usage instructions for various speculative decoding algorithms in PaddleNLP.
## Efficient Speculative Decoding Framework
Traditional methods for Draft Token verification and MTP (Eagle/Draft Model) inference typically expand batch_size by multiples of the Draft Token count. Our efficient attention mechanism maintains the original batch size while reducing computation, as shown in the following diagram:
![Framework Diagram](https://github.com/user-attachments/assets/fd938c8c-fcd5-4ead-ae6e-f455af415e52)
Reference [Vllm batch_extension](https://docs.google.com/document/d/1T-JaS2T1NRfdP51qzqpyakoCXxSXTtORppiwaj5asxA/edit?tab=t.0#heading=h.kk7dq05lc6q8)
## Parameter Description
- `speculate_method`: Speculative decoding algorithm. Default is `None`. Valid options: `None`, `inference_with_reference`, `mtp`, `eagle`.
- `None`: Regular autoregressive decoding.
- `inference_with_reference`: Context-based speculative decoding. [Paper Link](https://arxiv.org/pdf/2304.04487).
- `speculate_max_draft_token_num`: Maximum number of draft tokens generated per iteration in speculative decoding. Default is 1, maximum supported is 5.
- `speculate_max_ngram_size`: Maximum window size for n-gram matching of draft tokens. Default is `1`. In `inference_with_reference` algorithm, draft tokens are first matched from prompt using n-gram window sliding. Window size and input-output overlap jointly determine the draft token generation overhead, thus affecting the acceleration performance.
- `speculate_verify_window` (temporarily deprecated): Verification strategy defaults to TopP + window verification. Window size is 2 by default. For details, refer to [Speculative Decoding Tutorial](./speculative_decoding.md).
- `speculate_max_candidate_len` (temporarily deprecated): Maximum candidate tokens generated. Verification is performed by comparing candidate tokens with draft tokens (only effective in TopP + window verification). Default is 5.
- `draft_model_name_or_path`: Path to Draft Model in `MTP` or `EAGLE` mode.
- `draft_model_quant_type`: Inference quantization precision for Draft Model in `MTP` or `EAGLE` mode. Refer to `--quant_type`.
- `return_full_hidden_states`: In `MTP` or `EAGLE`...
## Whether to return all hidden states, defaults to `False`.
Others:
1. The maximum batch_size currently supported by speculative decoding is 128
## Inference with reference
This algorithm matches draft tokens from prompts using n-gram windows, suitable for scenarios with significant input-output overlap such as code editing, document querying, etc. For more information, refer to the [paper](https://arxiv.org/pdf/2304.04487).
### Usage commands
```shell
# Dynamic graph model inference command reference
python predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float16 --speculate_method inference_with_reference --speculate_max_draft_token_num 5 --speculate_max_ngram_size 2
```
## Multi-Token Prediction (MTP)
Paper: https://github.com/deepseek-ai/DeepSeek-V3/blob/main/DeepSeek_V3.pdf
![MTP](https://github.com/user-attachments/assets/6cdc3d94-7bab-4c0f-991c-875ae24816a6)
Supports inference for DeepSeek-V3/R1 & MTP. For detailed principles, please refer to the paper.
Key features:
1. During Base Model validation, optimized Attention is used to generate all Draft Token logits in one pass, eliminating the need for batch_extension to increase batch_size. This addresses the issue of speculative decoding failing to accelerate inference performance under large batches.
2. In the MTP inference phase, unified handling of Draft Token acceptance from previous rounds (e.g., full rejection, partial acceptance, full acceptance) is maintained, requiring only the original batch size to process all input requests at once.
3. Using a decoupled framework where Base Model and MTP load weights separately, supporting multiple decoding methods post-export.
### Supported Quantized Precisions for MTP
| Base Model | Deployment Machine | Base Model Quantization Type | MTP Quantization Type |
| --- | --- | --- | --- |
| DeepSeek-R1 | TP8 | a8w8_fp8_wint4 | a8w8_fp8 |
| DeepSeek-R1 | TP8 | weight_only_int4 | weight_only_int8 |
| DeepSeek-R1 | TP16(2*TP8) | a8w8_fp8 | a8w8_fp8 |
| DeepSeek-R1 | TP16(2*TP8) | weight_only_int8 | weight_only_int8 |
Supports mixed-precision inference combinations for DeepSeek-R1 and MTP. Deployment can be done via containers or scripts. Below are partial examples:
### Method 1: One-click Container Deployment

### Method 2: Script-based Inference Testing
#### DeepSeek_R1 Dynamic Graph + MTP Dynamic Graph, Dual-machine TP16
1. DeepSeek_R1 uses weight_only_int8, MTP uses weight_only_int8
```shell
For dual-machine inference, ensure nodes can ping each other:
# First node (master)
ping 192.168.0.1
# Second node (slave)
ping 192.168.0.2
```
node1 and node2 use identical scripts
```shell

--speculate_max_draft_token_num 1 \
--return_full_hidden_states 1 \
--mla_use_matrix_absorption 1
$ bash run_dynamic_mtp.sh
```
2. DeepSeek_R1 uses FP8, MTP uses FP8
Scripts for node1 and node2 are identical
```shell

```
#### [**Recommended**] Base Model Static Graph + MTP Dynamic Graph, Dual-machine TP16
> Notes:
1. The speculative decoding exported model supports all methods, so set speculate_method to the default inference_with_reference here.
2. The static graph model can be exported from DeepSeek-R1, or directly download the pre-uploaded model
```shell
# To launch dual-machine inference, ensure the two machine nodes can ping each other
# First node (master)
ping 192.168.0.1
# Second node (slave)
ping 192.168.0.2
```

Introduction to Large Model Pre-training
===============================
The PaddleNLP Large Model Toolkit supports pre-training for large models including LLaMA v1/v2, GPT-3, BaiChuan, Qwen, etc.
Clone the code to start:
.. code-block:: bash
git clone https://github.com/PaddlePaddle/PaddleNLP.git
# pip install ./PaddleNLP to use development version
cd PaddleNLP/llm
# Enter execution directory
.. _create-dataset:
Data Preparation
-----------------------------
Detailed workflow can be found in the following documentation:
.. toctree::
:maxdepth: 1
data/DataPreparation
.. _start_training:
Start Training
-------------------------
To facilitate users in testing and running this model, we provide a processed 100k-doc training sample:
.. code-block:: bash
# Download llama model data
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.bin
wget https://bj.bcebos.com/paddlenlp/models/transformers/llama/data/llama_openwebtext_100k.idx
# Download gpt model data
# wget https://bj.bcebos.com/paddlenlp/models/transformers/gpt/data/gpt_en_dataset_300m_ids.npy
# wget https://bj.bcebos.com/paddlenlp/models/transformers/gpt/data/gpt_en_dataset_300m_idx.npz
Organize all preprocessed files into a single directory for training:
.. code-block:: bash
mkdir data
mv llama_openwebtext_100k.bin ./data
mv llama_openwebtext_100k.idx ./data
.. code-block:: bash
# Compile custom operators (optional)
cd ../slm/model_zoo/gpt-3/external_ops/ && python3 setup.py install && cd -
# Pre-training for llama model
python -u -m paddle.distributed.launch --gpus "0,1,2,3,4,5,6,7" run_pretrain.py ./config/llama/pretrain_argument.json
# Pre-training for Qwen model
python -u -m paddle.distributed.launch --gpus "0,1,2,3,4,5,6,7" run_pretrain.py ./config/qwen/pretrain_argument.json
Notes:
1. It is recommended to use the paddle develop version for training. Requires installation of ``pip install ...`` (remain actual installation command unchanged)
```markdown
pip install fast_dataindex visualdl==2.5.3`` and other missing whl packages.
2. ``use_flash_attention`` requires enabling on A100 machines, recommended to use cuda11.8 environment.
3. ``use_fused_rms_norm`` requires installing custom OPs from `this directory <https://github.com/PaddlePaddle/PaddleNLP/tree/develop/slm/model_zoo/gpt-3/external_ops>`_ via `python setup.py install`. If operators are still not found after installation, additional ``PYTHONPATH`` settings are required.
4. ``continue_training`` indicates loading training from an existing pre-trained model. The initial loss for 7B model is approximately 2.xx, while randomly initialized models start from loss around 11.x and decrease.
5. Current script is the sharding version. For users requiring 4D parallel training (data, sharding, tensor, pipeline parallelism), please refer to ``run_trainer_tp4pp2.sh`` script.
6. During multi-machine training, if all machines use training data files from the same location (e.g., mounted shared storage), specify ``--share_folder true`` to have global rank 0 create cached data. Otherwise, rank 0 on each machine will create cached data independently by default.
7. If the default cache folder ``index-cache/`` exists in the dataset directory, the additionally specified ``--data_cache`` will not take effect, and training will prioritize loading content from the default cache folder.
The pre-training uses PaddleNLP's Trainer module. For related distributed strategy usage, please refer to the `Large Model Trainer Hybrid Parallel Training Tutorial <./llm_trainer.rst>`.

# PaddlePaddle Large Model Suite PRM Documentation
## 1. Algorithm Overview
The Process Reward Model (PRM) provides reward signals for each reasoning step and the final answer, addressing the issue where Final Answer Incorrect but Process Correct (FP) cases might be mistakenly awarded positive rewards in Outcome Reward Models (ORM).
Implementation-wise, PRM employs next token prediction with binary classification at the end of each step to determine correctness.
## 2. Quick Start
Here we demonstrate PRM implementation using **Llama 3** as an example.
### 2.1 Environment Setup
- PaddlePaddle 3.0-beta
- PaddleNLP develop
Clone the repository to begin:
```bash
git clone https://github.com/PaddlePaddle/PaddleNLP.git
# pip install ./PaddleNLP (use develop version)
cd PaddleNLP/llm
# Proceed to working directory
```
### 2.2 Data Preparation

# Large Model Quantization Tutorial
## 1. Algorithm Introduction
Large model quantization converts 16-bit and 32-bit floating-point model parameters or activations into 4-bit or 8-bit integers, effectively reducing model storage space and computational resource requirements while accelerating inference. The quantization algorithms include:
- **PTQ**. The adaptive PiecewiseSearchSmooth (PSS) quantization algorithm independently developed by the PaddleSlim team. Based on [SmoothQuant](https://arxiv.org/abs/2211.10438) and [Outlier Suppression+](https://arxiv.org/abs/2304.09145), it introduces the PieceWiseSearch parameter search algorithm and extends it to **all linear layers**, adjusting model weights and activation distributions to reduce subsequent A8W8 PTQ quantization loss.
- **GPTQ**. [GPTQ](https://arxiv.org/abs/2210.17323) is an industry-leading weight quantization algorithm that enables lossless 4-bit integer quantization of large model weights to improve inference speed.
- **AWQ**. [AWQ](https://arxiv.org/abs/2306.00978) is another industry-leading weight quantization algorithm that allows lossless 4-bit integer quantization of large model weights to enhance inference speed.

## 2. Quick Start
### 2.1 Environment Setup
- PaddleSlim develop
- PaddlePaddle develop
- PaddleNLP develop
Clone the code repository to get started:
```shell
git clone https://github.com/PaddlePaddle/PaddleNLP.git
# pip install ./PaddleNLP to use the develop version
cd PaddleNLP/llm
# Navigate to the execution directory
```
### 2.2 Data Preparation
By default, the quantization process uses the training set as the calibration dataset and the development set as the evaluation dataset. For user convenience, we provide an example dataset [Advertisement Generation Dataset](https://bj.bcebos.com/paddlenlp/datasets/examples/AdvertiseGen.tar.gz). To use other data as the calibration dataset, create a `quant.json` file in the data directory. Users can also format their own datasets by following our data structure. The supported data format requires each line to contain a dictionary with the following fields:
- `src`: `str, List(str)`, the model's input instruction (instruction), prompt, or task description.
`tgt`: `str, List(str)`, model's output.
Sample data:
```text
{"src": "type#dress*color#blue*style#fresh*pattern#bow", "tgt": "The dress features 3D bow decorations with blue ribbon accents, creating a full-bodied silhouette with layered details while infusing a touch of sweetness. This highlights the girl's fresh and charming appearance."}
...
```
In addition to the above dataset, you can also extract part of the C-Eval training dataset as calibration data. Use the following commands to download the data to the current folder and unzip it:
```shell
mkdir dataset
wget https://huggingface.co/datasets/ceval/ceval-exam/resolve/main/ceval-exam.zip
unzip ceval-exam.zip -d dataset/ceval
```
Use the following script and commands to extract C-Eval samples as calibration dataset:
```shell
cd llm/experimental/ceval/default
python prepare_data_for_ptq.py
```
The default generated calibration dataset is located at `dataset/ceval_ptq`.

### 2.8 Quantization Parameters
<summary>&emsp; Quantization Parameters (QuantArgument)</summary>
<div>
- `quant_type`: PTQ, QAT quantization type, default a8w8 (case insensitive). Supported types: a8w8, a8w8c8, a8w8_fp8, wint4/weight_only_int4, wint8/weight_only_int8:
- a8w8: 8-bit quantization for activations (input) and INT8 quantization for model weights
- a8w8c8: INT8 quantization for activations, weights, and kvcache
- a8w8_fp8: FP8 quantization for activations and weights
- wint4/weight_only_int4: INT4 weight-only quantization for model weights, followed by WeightOnly inference
- wint8/weight_only_int8: INT8 weight-only quantization for model weights, followed by WeightOnly inference
- `fp8_type`: FP8 quantization type, specifies fp8 types for activation and weight, default `["e4m3","e4m3"]`.
- `do_ptq`
Whether to perform PTQ quantization, defaults to False.
- `weight_quant_method`: Weight quantization method. For INT8 quantization, options are groupwise or abs_max_channel_wise; for FP8 quantization, options are abs_max or avg.
- `act_quant_method`: Activation quantization method. For INT8, options are avg or abs_max; for FP8, options are abs_max or avg.
- `cachekv_quant_method`: kvcache quantization method, currently options are abs_max_headwise or avg_headwise.
- `ptq_step`: Number of steps for PTQ quantization (i.e., forward passes), defaults to 32.
- `shift`: Whether to apply [Shift strategy](https://arxiv.org/abs/2304.09145) before PTQ quantization, defaults to False. Requires `do_ptq` to be True.
- `shift_all_linear`: Whether to apply Shift to all Linear layers in the model. If True, Shift will be applied to Linear layers not in LayerNorm-Linear combinations, and two additional ops will be added, defaults to False.
- `shift_sampler`: Sampler for Shift strategy, defaults to none. Options: none, ema. "none" means directly use MinMax to calculate zero points in Shift; "ema" uses exponential moving average to calculate zero points.
- `shift_step`: Number of sampling steps for Shift (i.e., forward passes), defaults to 32.
- `smooth`: Whether to apply [SmoothQuant strategy](https://arxiv.org/abs/2211.10438) before PTQ quantization, defaults to False. Requires `do_ptq` to be True.
- `smooth_all_linears`: Whether to apply Smooth to all Linear layers in the model. If True, Smooth will be applied to Linear layers not in LayerNorm-Linear combinations, and two additional ops will be added, defaults to False.
- `smooth_sampler`: Sampler for Smooth strategy, defaults to none. Options: none, multi_step. "multi_step" saves multiple forward passes for computation, requiring more memory.
- `smooth_step`: Number of sampling steps for Smooth (i.e., forward passes), defaults to 32.
- `smooth_piecewise_search`: Whether to perform piecewise search in Smooth, defaults to False. Piecewise search divides activations into K segments based on value ranges, and searches for alpha and scale per segment.
- `smooth_k_piece`: Number of segments for piecewise search, defaults to 3. Empirical suggestion: 3 for 10B models, 6 for 100B models.
- `smooth_search_piece`: Whether to search for optimal number of segments during piecewise search, defaults to False. When True, it's recommended to set `smooth_k_piece` to 6. Segment number search is time-consuming; disable for faster Smooth process.
- `search_alpha_min`: Minimum alpha value for piecewise search, defaults to 0.2.
- `search_alpha_max`: Maximum alpha value for piecewise search, defaults to 0.8.
- `search_scale_min`
- `search_scale_min`: Minimum scale value for segmented search, default is 1.0.
- `search_scale_max`: Maximum scale value for segmented search, default is 5.0.
- `load_quant_model`: Whether to load quantized model, default is False. Used to validate the effect of quantized models. When set to True, weights will be loaded from output_dir. Enabling this requires setting `do_ptq` to False. If smooth or shift was used during quantization, the same configuration must be maintained when loading (shift_step/search_step can be set to 8). Note: Currently only supports loading in pdparams format. To use this feature, set `"unified_checkpoint": false`.
- `skip_list_names`: List of layer names to skip during quantization, default is empty list. Partial string matching can be used, e.g. ['down_proj'] will skip all ffn2 layers.
- `do_gptq`: Whether to perform GPTQ quantization. GPTQ implements WINT4 quantization, providing higher precision than regular PTQ but requiring longer quantization time. Default is False.
- `gptq_step`: Number of steps for GPTQ quantization (i.e., forward passes), default is 8.
- `do_awq`: Whether to perform AWQ quantization. AWQ implements WINT4 quantization, providing higher precision than regular PTQ. Default is False.
- `auto_clip`: Whether to perform automatic truncation value search and weight truncation during AWQ. Truncation improves quantized model precision but slows down search. Default is False.
- `autoclip_step`: Number of steps for AutoClip (i.e., forward passes). During sampling, data is concatenated for truncation value search, default is 8.
</div>
<summary>&emsp; Other Parameters</summary>
