News

• [2021-06-04] ERNIE-Gram pretrained model has been released! Install v2.0.2 to try it.
• [2021-05-20] PaddleNLP 2.0 has been officially relealsed! 🎉 For more information please refer to Release Note.

Introduction

PaddleNLP 2.0 aims to accelerate NLP applications through powerful model zoo, easy-to-use API and high performance distributed training. We also provide NLP best practice based on PaddlePaddle 2.0 API system.

Feature

• Easy-to-Use and End-to-End API

  • The API is fully integrated with PaddlePaddle 2.0 high-level API system. It minimizes the number of user actions required for common use cases like data loading, text pre-processing, transformer model loading, training and deployment, which enables you to deal with text problems more productively.

• Rich Application Examples

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

• High Performance Distributed Training

  • We provide a highly optimized ditributed training implementation for BERT with Fleet API, and 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 >= 2.1

More information about PaddlePaddle installation please refer to PaddlePaddle Install

PIP Installation

pip install --upgrade paddlenlp -i https://pypi.org/simple

Quick Start

Quick Dataset Loading

from paddlenlp.datasets import load_dataset

train_ds, dev_ds, test_ds = load_dataset("chnsenticorp", splits=["train", "dev", "test"])

For more dataset API usage please refer to Dataset API.

Pre-trained Text Embedding Loading

from paddlenlp.embeddings import TokenEmbedding

wordemb = TokenEmbedding("fasttext.wiki-news.target.word-word.dim300.en")
wordemb.cosine_sim("king", "queen")
>>> 0.77053076
wordemb.cosine_sim("apple", "rail")
>>> 0.29207364

For more TokenEmbedding usage, please refer to Embedding API

Rich Chinese Pre-trained Models

from paddlenlp.transformers import *

ernie = ErnieModel.from_pretrained('ernie-1.0')
bert = BertModel.from_pretrained('bert-wwm-chinese')
albert = AlbertModel.from_pretrained('albert-chinese-tiny')
roberta = RobertaModel.from_pretrained('roberta-wwm-ext')
electra = ElectraModel.from_pretrained('chinese-electra-small')
gpt = GPTForPretraining.from_pretrained('gpt-cpm-large-cn')

For more pretrained model selection, please refer to Transformer API

Extract Feature Through Pre-trained Model

import paddle
from paddlenlp.transformers import ErnieTokenizer, ErnieModel

tokenizer = ErnieTokenizer.from_pretrained('ernie-1.0')
model = ErnieModel.from_pretrained('ernie-1.0')

text = tokenizer('自然语言处理')
pooled_output, sequence_output = model.forward(input_ids=paddle.to_tensor([text['input_ids']]))

More API Usage

• Transformer API
• Data API
• Dataset API
• Embedding API
• Metrics API

Please find more API Reference from our readthedocs.
