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.

Getting Started with TensorFlow 2.0

This book aims to familiarize readers with the new features introduced in TensorFlow 2.0 (TF 2.0) and to empower you to unlock its potential while building machine learning applications. This chapter provides a bird's-eye view of new architectural and API-level changes in TF 2.0. We will cover TF 2.0 installation and setup, and will compare the changes with respect to TensorFlow 1.x (TF 1.x), such as Keras APIs and layer APIs. We will also cover the addition of rich extensions, such as TensorFlow Probability, Tensor2Tensor, Ragged Tensors, and the newly available custom training logic for loss functions. This chapter also summarizes the changes to the layers API and other APIs.

The following topics will be covered in this chapter:
