fastNLP

Build Status codecov Pypi Hex.pm Documentation Status

fastNLP是一款轻量级的自然语言处理(NLP)工具包,目标是快速实现NLP任务以及构建复杂模型。

fastNLP具有如下的特性:

  • 统一的Tabular式数据容器,简化数据预处理过程;
  • 内置多种数据集的Loader和Pipe,省去预处理代码;
  • 各种方便的NLP工具,例如Embedding加载(包括ELMo和BERT)、中间数据cache等;
  • 部分数据集与预训练模型的自动下载;
  • 提供多种神经网络组件以及复现模型(涵盖中文分词、命名实体识别、句法分析、文本分类、文本匹配、指代消解、摘要等任务);
  • Trainer提供多种内置Callback函数,方便实验记录、异常捕获等。

安装指南

fastNLP 依赖以下包:

  • numpy>=1.14.2
  • torch>=1.0.0
  • tqdm>=4.28.1
  • nltk>=3.4.1
  • requests
  • spacy
  • prettytable>=0.7.2

其中torch的安装可能与操作系统及 CUDA 的版本相关,请参见 PyTorch 官网 。 在依赖包安装完成后,您可以在命令行执行如下指令完成安装

pip install fastNLP
python -m spacy download en

内置组件

大部分用于的 NLP 任务神经网络都可以看做由词嵌入(embeddings)和两种模块:编码器(encoder)、解码器(decoder)组成。

以文本分类任务为例,下图展示了一个BiLSTM+Attention实现文本分类器的模型流程图:

fastNLP 在 embeddings 模块中内置了几种不同的embedding:静态embedding(GloVe、word2vec)、上下文相关embedding (ELMo、BERT)、字符embedding(基于CNN或者LSTM的CharEmbedding)

与此同时,fastNLP 在 modules 模块中内置了两种模块的诸多组件,可以帮助用户快速搭建自己所需的网络。 两种模块的功能和常见组件如下:

类型 功能 例子
encoder 将输入编码为具有具有表示能力的向量 Embedding, RNN, CNN, Transformer, ...
decoder 将具有某种表示意义的向量解码为需要的输出形式 MLP, CRF, ...

项目结构

fastNLP的大致工作流程如上图所示,而项目结构如下:
