Mastering TensorFlow 1.x

Overview of this book

TensorFlow is the most popular numerical computation library built from the ground up for distributed, cloud, and mobile environments. TensorFlow represents the data as tensors and the computation as graphs. This book is a comprehensive guide that lets you explore the advanced features of TensorFlow 1.x. Gain insight into TensorFlow Core, Keras, TF Estimators, TFLearn, TF Slim, Pretty Tensor, and Sonnet. Leverage the power of TensorFlow and Keras to build deep learning models, using concepts such as transfer learning, generative adversarial networks, and deep reinforcement learning. Throughout the book, you will obtain hands-on experience with varied datasets, such as MNIST, CIFAR-10, PTB, text8, and COCO-Images. You will learn the advanced features of TensorFlow1.x, such as distributed TensorFlow with TF Clusters, deploy production models with TensorFlow Serving, and build and deploy TensorFlow models for mobile and embedded devices on Android and iOS platforms. You will see how to call TensorFlow and Keras API within the R statistical software, and learn the required techniques for debugging when the TensorFlow API-based code does not work as expected. The book helps you obtain in-depth knowledge of TensorFlow, making you the go-to person for solving artificial intelligence problems. By the end of this guide, you will have mastered the offerings of TensorFlow and Keras, and gained the skills you need to build smarter, faster, and efficient machine learning and deep learning systems.

Distributed Models with TensorFlow Clusters

Previously we learned how to run TensorFlow models at scale in production using Kubernetes, Docker and TensorFlow serving. TensorFlow serving is not the only way to run TensorFlow models at scale. TensorFlow provides another mechanism to not only run but also train the models on different nodes and different devices on multiple nodes or the same node. In chapter 1, TensorFlow 101, we also learned how to place variables and operations on different devices. In this chapter, we shall learn how to distribute the TensorFlow models to run on multiple devices across multiple nodes.

In this chapter, we shall cover the following topics:

  • Strategies for distributed execution
  • TensorFlow clusters
  • Data parallel models
  • Asynchronous and synchronous updates to distributed models
