I wanna train my agent in CarRacing-v0 environment, but instead of box action/observation spaces I want to use discrete spaces so I can train it with DQN algorithm. there is a sayin in openai-gym that says: "Discreet control is reasonable in this environment as well, on/off discretisation is fine." https://gym.openai.com/envs/CarRacing-v0/
but I dont know how to do it in code or in pragmatic way.
