Overview of this book

Deep Learning with TensorFlow and Keras teaches you neural networks and deep learning techniques using TensorFlow (TF) and Keras. You'll learn how to write deep learning applications in the most powerful, popular, and scalable machine learning stack available. TensorFlow 2.x focuses on simplicity and ease of use, with updates like eager execution, intuitive higher-level APIs based on Keras, and flexible model building on any platform. This book uses the latest TF 2.0 features and libraries to present an overview of supervised and unsupervised machine learning models and provides a comprehensive analysis of deep learning and reinforcement learning models using practical examples for the cloud, mobile, and large production environments. This book also shows you how to create neural networks with TensorFlow, runs through popular algorithms (regression, convolutional neural networks (CNNs), transformers, generative adversarial networks (GANs), recurrent neural networks (RNNs), natural language processing (NLP), and graph neural networks (GNNs)), covers working example apps, and then dives into TF in production, TF mobile, and TensorFlow with AutoML.

An introduction to OpenAI Gym

We will be using OpenAI Gym to provide an environment for our agent. OpenAI Gym is an open source toolkit to develop and compare RL algorithms. It contains a variety of simulated environments that can be used to train agents and develop new RL algorithms.

The first thing to do is install OpenAI Gym. The following command will install the minimal gym package:

pip install gym

If you want to install all (free) gym modules, add [all] after it:

pip install gym[all]

The MuJoCo environment requires a purchasing license. For Atari-based games, you will need to install Atari dependencies (Box2D and ROM):

pip install box2d-py

OpenAI Gym provides a variety of environments, from simple text-based to three-dimensional games. The environments supported can be grouped as follows:

  • Algorithms: Contains environments that involve performing computations such as addition. While we can easily perform the computations...
