Hands-On ROS for Robotics Programming

Installing OpenAI Gym

As we did in the previous chapter, we are going to create a virtual environment for the Python setup of this chapter, which we will call gym. The following two commands allow for the creation and then the activation of gym:

$ conda create -n gym pip python=2.7$ conda activate gym

Following this, install the specific Python packages that we are going to need for the examples:

• The Keras package (https://keras.io/), which is a high-level neural network API that it used within OpenAI Gym. Remember that it was also used in the previous chapter, but we need to install it again because this is a new gym environment. Keras will let us train an agent using the DQN (short for Deep Q-Network) algorithm, which is deep learning-b ...
