This codebase provides a Natrual Language Processing modeling toolkit written in
[TF2](https://www.tensorflow.org/guide/effective_tf2). It allows researchers and
developers to reproduce state-of-the-art model results and train custom models
to experiment new research ideas.

## Features

* Reusable and modularized modeling building blocks
* State-of-the-art reproducible
* Easy to customize and extend
* End-to-end training
* Distributed trainable on both GPUs and TPUs

## Major components

### Libraries

We provide modeling library to allow users to train custom models for new
research ideas. Detailed intructions can be found in READMEs in each folder.

*   [modeling/](modeling): modeling library that provides building blocks
    (e.g.,Layers, Networks, and Models) that can be assembled into
    transformer-based achitectures .
*   [data/](data): binaries and utils for input preprocessing, tokenization,
    etc.

### State-of-the-Art models and examples

We provide SoTA model implementations, pre-trained models, training and
evaluation examples, and command lines. Detail instructions can be found in the
READMEs for specific papers. Below are some papers implemented in the
repository and more NLP projects can be found in the
[`projects`](https://github.com/tensorflow/models/tree/master/official/projects)

### Common Training Driver

We provide a single common driver [train.py](train.py) to train above SoTA
models on popluar tasks. Please see [docs/train.md](docs/train.md) for
more details.


### Pre-trained models with checkpoints and TF-Hub

We provide a large collection of baselines and checkpoints for NLP pre-trained
models. Please see [docs/pretrained_models.md](docs/pretrained_models.md) for
more details.
