In this section, we'll get familiar with the OpenAI Gym package and learn how to get it up and running in your Python development environment.
Getting started with OpenAI Gym
What is Gym?
OpenAI Gym is a toolkit of environments for building RL algorithms. In the context of RL, an environment refers to the actual task (a Markov decision process or MDP) that is to be solved by the algorithm. The state and action spaces of the task are defined by the environment.
Be careful not to get the RL use of the word environment confused with others that we might use in different contexts, such as a Python development environment or a Unix/Linux environment. Those terms refer to very different things.
