Dependency list not provided (environment.yml file)

[MasterScrat]

I can't find a clear dependency list for this project, such as a requirements.txt or environment.yml file.

This is problematic, for example if I spin up the repo on Colab, it won't run as gym has introduced breaking changes. Installing gym[atari]==0.10.8 works, but the latest version gym[atari]==0.17.1 doesn't.
