After making several changes in order to get it to this point (turning ObservationType into ObsType), I encounter this error which I do not know how to fix.

pip uninstall poke-env and pip install git+https://github.com/hsahovic/poke-env/ then it will fix them https://github.com/hsahovic/poke-env/commit/21755b520d582c1b7da01125f9f825fcbc8eb2c8 Looks like it hasn't been released since gym was replaced by gymnasium.

but I start getting strange error messages (WARNING:root:AAAHHHH) in accept_challenges.

How can I solve the problem, is it solved by installing poke-env?
