@qgallouedec just so you know, python 3.7 is giving the same error as https://github.com/DLR-RM/rl-baselines3-zoo/issues/342#issuecomment-1400424190 for the new minigrid env (I realised you just pushed it recently, I was a bit confused at first ^^#). As python 3.7 support will be dropped soon (end of life in June 23), I think it's fine to skip it.
