Earlier this year, we released a TensorFlow implementation of a state-of-the-art image classification model known as Inception-V3. This code allowed users to train the model on the ImageNet classification dataset via synchronized gradient descent, using either a single local machine or a cluster of machines. The Inception-V3 model was built on an experimental TensorFlow library called TF-Slim, a lightweight package for defining, training and evaluating models in TensorFlow. The TF-Slim library provides common abstractions which enable users to define models quickly and concisely, while keeping the model architecture transparent and its hyperparameters explicit.

Since that release, TF-Slim has grown substantially, with many types of layers, loss functions, and evaluation metrics added, along with handy routines for training and evaluating models. These routines take care of all the details you need to worry about when working at scale, such as reading data in parallel, deploying models on multiple machines, and more. Additionally, we have created the TF-Slim Image Models library, which provides definitions and training scripts for many widely used image classification models, using standard datasets. TF-Slim and its components are already widely used within Google, and many of these improvements have already been integrated into tf.contrib.slim.

Today, we are proud to share the latest release of TF-Slim with the TF community. Some highlights of this release include:
Want to get started using TF-Slim? See the README for details. Interested in working with image classification models? See these instructions or this Jupyter notebook.

The release of the TF-Slim library and the pre-trained model zoo has been the result of widespread collaboration within Google Research. In particular we want to highlight the vital contributions of the following researchers:
  • TF-Slim: Sergio Guadarrama, Nathan Silberman.
  • Model Definitions and Checkpoints: Christian Szegedy, Sergey Ioffe, Vincent Vanhoucke, Jon Shlens, Zbigniew Wojna, Vivek Rathod, George Papandreou, Alex Alemi
  • Systems Infrastructure: Jon Shlens, Matthieu Devin, Martin Wicke
  • Jupyter notebook: Nathan Silberman, Kevin Murphy
