sb3 training error: AssertionError: The algorithm only supports (<class 'gymnasium.spaces.box.Box'>... #119

Closed Ivan-267 closed 1 year ago

Test on my newest PR (which is a simple .md file change) failed: https://github.com/edbeeching/godot_rl_agents/pull/118/checks, a user also reported the same error on Discord with JumperHard.x86_64, and I was able to confirm the error on Windows with the gdrl command as well by uninstalling stable baselines and installing gdrl again using pip install godot-rl.

The error is: AssertionError: The algorithm only supports (<class 'gymnasium.spaces.box.Box'>, <class 'gymnasium.spaces.discrete.Discrete'>, <class 'gymnasium.spaces.multi_discrete.MultiDiscrete'>, <class 'gymnasium.spaces.multi_binary.MultiBinary'>) as action spaces but Box(-1.0, 1.0, (2,), float32) was provided

In my yesterday's PR the tests passed, so I checked to find differences, and so far I found some differences: New (failing test): 

platform linux -- Python 3.7.17, pytest-7.4.0, pluggy-1.2.0

Breaking Changes:

Switched to Gymnasium as primary backend, Gym 0.21 and 0.26 are still supported via the shimmy package
