models README

Welcome to the Model Garden for TensorFlow

The TensorFlow Model Garden is a repository with a number of different implementations of state-of-the-art (SOTA) models and modeling solutions for TensorFlow users. We aim to demonstrate the best practices for modeling so that TensorFlow users can take full advantage of TensorFlow for their research and product development.

To improve the transparency and reproducibility of our models, training logs on TensorBoard.dev are also provided for models to the extent possible though not all models are suitable.

Directory	Description
official	• A collection of example implementations for SOTA models using the latest TensorFlow 2's high-level APIs • Officially maintained, supported, and kept up to date with the latest TensorFlow 2 APIs by TensorFlow • Reasonably optimized for fast performance while still being easy to read For more details on the capabilities, check the guide on the Model-garden
research	• A collection of research model implementations in TensorFlow 1 or 2 by researchers • Maintained and supported by researchers
community	• A curated list of the GitHub repositories with machine learning models and implementations powered by TensorFlow 2
orbit	• A flexible and lightweight library that users can easily use or fork when writing customized training loop code in TensorFlow 2.x. It seamlessly integrates with `tf.distribute` and supports running on different device types (CPU, GPU, and TPU).

Installation

To install the current release of tensorflow-models, please follow any one of the methods described below.

Method 1: Install the TensorFlow Model Garden pip package

tf-models-official is the stable Model Garden package. Please check out the releases to see what are available modules.

pip3 will install all models and dependencies automatically.

pip3 install tf-models-official

Please check out our examples:

basic library import
nlp model building to learn how to use a PIP package.

Note that tf-models-official may not include the latest changes in the master branch of this github repo. To include latest changes, you may install tf-models-nightly, which is the nightly Model Garden package created daily automatically.

pip3 install tf-models-nightly

Method 2: Clone the source

Clone the GitHub repository:

git clone https://github.com/tensorflow/models.git

Add the top-level /models folder to the Python path.

export PYTHONPATH=$PYTHONPATH:/path/to/models

If you are using in a Windows environment, you may need to use the following command with PowerShell:

$env:PYTHONPATH += ":\path\to\models"

If you are using a Colab notebook, please set the Python path with os.environ.

import os
os.environ['PYTHONPATH'] += ":/path/to/models"

Install other dependencies

pip3 install --user -r models/official/requirements.txt

Finally, if you are using nlp packages, please also install tensorflow-text-nightly:

pip3 install tensorflow-text-nightly
