Summary
You have started to learn about the practical side of RL! In this chapter, we installed OpenAI Gym, with its tons of environments to play with. We studied its basic API and created a randomly behaving agent.
You also learned how to extend the functionality of existing environments in a modular way and became familiar with a way to record our agent's activity using the Monitor
class. This will be heavily used in the upcoming chapters.
In the next chapter, we will do a quick DL recap using PyTorch, which is a favorite library among DL researchers. Stay tuned.
