I've seen this issue closed already but I tried the proposed solutions and am getting the same errors:

It might be helpful to note that I'm using python virtual environments.

Hi @profversaggi , thank you for the detailed post. I see that you already are following the issue and tried the resolutions proposed in the issue page on the OpenAI Gym library repo. This issue seems to be with the OpenAI Gym code in the version you are using as per your pip list output. Here are the two options you can try to resolve the issue:

  1. Setup your python virtual environment using this conda environment definition and then continue with your experiments with the book. E.g. running: python run_gym_env.py Alien-ram-v4 2000
  2. If you want to use the latest OpenAI Gym version (0.23.1) with ale-py 0.7.4 please use v5 of the Alien-ram env using the environment ID: ALE/Alien-ram-v5 instead of Alien-ram-v4.

I hope that helps you.
