Introduction

PaddleNLP aims to accelerate NLP applications through powerful model zoo, easy-to-use API and high performance distributed training. It's also the NLP best practice for PaddlePaddle 2.0 API system.

Features

• Rich and Powerful Model Zoo

  • Our Model Zoo covers mainstream NLP applications, including Lexical Analysis, Syntactic Parsing, Machine Translation, Text Classification, Text Generation, Text Matching, General Dialogue and Question Answering etc.

• Easy-to-use and End-to-End API

  • The API is fully integrated with PaddlePaddle high-level API system. It minimizes the number of user actions required for common use cases like data loading, text pre-processing, training and evaluation. which enables you to deal with text problems more productively.

• High Performance and Distributed Training

• We provide a highly optimized ditributed training implementation for BERT with Fleet API, bnd based the mixed precision training strategy based on PaddlePaddle 2.0, it can fully utilize GPU clusters for large-scale model pre-training.

Installation

Prerequisites

• python >= 3.6
• paddlepaddle >= 2.0.0

pip install paddlenlp>=2.0.0rc

Quick Start

Quick Dataset Loading

from paddlenlp.datasets import ChnSentiCorp

train_ds, test_ds = ChnSentiCorp.get_datasets(['train','test'])

Chinese Text Emebdding Loading

from paddlenlp.embeddings import TokenEmbedding

wordemb = TokenEmbedding("w2v.baidu_encyclopedia.target.word-word.dim300")
print(wordemb.cosine_sim("国王", "王后"))
>>> 0.63395125
wordemb.cosine_sim("艺术", "火车")
>>> 0.14792643

Rich Chinsese Pre-trained Models

from paddlenlp.transformers import ErnieModel, BertModel, RobertaModel, ElectraModel, GPT2ForPretraining

ernie = ErnieModel.from_pretrained('ernie-1.0')
bert = BertModel.from_pretrained('bert-wwm-chinese')
roberta = RobertaModel.from_pretrained('roberta-wwm-ext')
electra = ElectraModel.from_pretrained('chinese-electra-small')
gpt2 = GPT2ForPretraining.from_pretrained('gpt2-base-cn')
