What's New in TensorFlow 2.0

By: Ajay Baranwal, Alizishaan Khatri, Tanish Baranwal

Overview of this book

TensorFlow is an end-to-end machine learning platform for experts as well as beginners, and its new version, TensorFlow 2.0 (TF 2.0), improves its simplicity and ease of use. This book will help you understand and utilize the latest TensorFlow features. What's New in TensorFlow 2.0 starts by focusing on advanced concepts such as the new TensorFlow Keras APIs, eager execution, and efficient distribution strategies that help you to run your machine learning models on multiple GPUs and TPUs. The book then takes you through the process of building data ingestion and training pipelines, and it provides recommendations and best practices for feeding data to models created using the new tf.keras API. You'll explore the process of building an inference pipeline using TF Serving and other multi-platform deployments before moving on to explore the newly released AIY, which is essentially do-it-yourself AI. This book delves into the core APIs to help you build unified convolutional and recurrent layers and use TensorBoard to visualize deep learning models using what-if analysis. By the end of the book, you'll have learned about compatibility between TF 2.0 and TF 1.x and be able to migrate to TF 2.0 smoothly.

Keras Default Integration and Eager Execution

This chapter covers two high-level TensorFlow 2.0 (TF 2.0) APIs—Keras and Estimators. Focusing on the concepts of lazy evaluation and eager execution, this chapter highlights the difference between how the underlying compute graphs are evaluated in TensorFlow 1.x (TF 1.x) and TF 2.0. This chapter also presents a detailed guide on building custom models (using custom low-level operations) using a high-level API such as Keras.

The following topics will be covered in this chapter:

  • New abstractions in TF 2.0
  • Diving deep into the Keras API
  • Estimators
  • Evaluating TensorFlow graphs
