[Bug Report] AtariPreprocessing Wrapper is unavailable

[sdpkjc]

Describe the bug

AtariPreprocessing Wrapper does not seem to be available. Probably because of the lack of interfaces, no good solution has been thought of yet.

Code example

import gymnasium as gym

env = gym.make("GymV26Environment-v0", env_id="ALE/Breakout-v5")
env = gym.wrappers.AtariPreprocessing(env, frame_skip=1)

Output:

❯ python a.py
A.L.E: Arcade Learning Environment (version 0.8.0+919230b)

Thanks for the issue, that is an interesting problem.

In v0.27, we have solved the atari with pip install shimmy[atari] such that gymnasium.make("ALE/Pong-v5") works.
Could you test this with shimmy and see if the same issues exist.

[sdpkjc]

Thank you for your reply. The problem seems to have been resolved after installing shimmy[atari].

import gymnasium as gym

env = gym.make(id="ALE/Breakout-v5")
env = gym.wrappers.AtariPreprocessing(env, frame_skip=1)

There is no error message in this code.

The existence of this problem also seems to indicate that the test code is not perfect, will future versions consider improving this part of the test?

[pseudo-rnd-thoughts]

Yes, I have opened an issue on this, it should be solved by the next release
