Compatibility Issues in train_SAC.py

[AlbertoGigantelliGabriele]

The training seems to be starting properly. The only hitch is found in gym==0.21.0 "extras_require" which in this version has an error in the setup.py file specifying the "other" version: ["lz4>=3.1.0", "opencv-python >=3 ."], so I recommend manually fixing the error and installing it manually.

Hey! Thanks for bringing that to my attention! I just pushed a new requirements.txt file containing working versions for packages (at least working on my Python 3.8.10).

I should have specified these earlier. Both stable-baselines3 and gym have moved on to a newer version of a gym called gymnasium, which made my gym environment obsolete. I could not find a virtual environment on my computer that made the project work, so I just looked at the date of my last working commit, took releases for both packages before that date, and tested them.

Let me know if it works so I can close the issue.
