Is there a way to slow down the game environment with gym’s OpenAI?

Question

When I render an environment with gym it plays the game so fast that I can’t see what is going on. And it shouldn’t be a problem with the code because I tried a lot of different ones.

Answer 1

Use time.sleep(.1) after every render.

Answer 2

You can manually control the frame rate using the 'fps' argument:

import gym

env = gym.make("CartPole-v1", render_mode="rgb_array")

gym.utils.play.play(env, fps=8)

This applies for playing an environment, but not for simulating one.
