JumperHarder example not working

[derkork]

I installed godot-rl and tried to run the JumperHarder example. I started gdrl at the console and ran the example using the play button in the Godot editor. The gdrl process exits with this exception:

Successfully installed godot-rl-0.4.7

Same for the BallChase example. Looks to me like some library problem, but I have not enough experience with Python to fix it myself.

[derkork]

I was able to fix it by creating a new Conda environment with Python 3.10 and running pip install https://github.com/edbeeching/godot_rl_agents/archive/refs/heads/main.zip (the master version).

hi @derkork this should be fixed with the latest version of godot-rl, please try and fresh installation with pip install godot-rl and let me know if you have any further issues.

@derkork , did it work? Ok to close the issue?

[derkork]

Yes, thank you very much!
