Environment Breakout doesn't exist in namespace ALE. #473

Hi, I get this error in a new Colab environment : Environment Breakout doesn't exist in namespace ALE.

Steps to reproduce

import gym
print(gym.__version__)
gym.make("ALE/Breakout-v5") # <--- fail here

The gym version is 0.25.2. ALE should be inside gym

I looked at this doc: gym api Breakout

Hi @francesco-taioli,

It's likely that you hadn't installed any ROMs. The ALE doesn't ship with ROMs and you'd have to install them yourself. If you had already installed them I'd need some more info to help debug this issue. Let me know if you're still encountering this issue within Colab and I can try to assist further.
