After this long detour into reinforcement learning and the DQN approach, we are finally ready to start coding, having all the basic understanding of how to operate an OpenAI Gym environment and how to set a DQN approximation of a Q function. We simply start importing all the necessary packages:
import gymfrom gym import wrappersimport numpy as npimport random, tempfile, osfrom collections import dequeimport tensorflow as tf
The tempfile module generates temporary files and directories that can be used as a temporary storage area for data files. The deque command, from the collections module, creates a double-ended queue, practically a list where you can append items at the start or at the end. Interestingly, it can be ...
