I don't even know where to start with this...

Hey. Which MineRL version you installed? The one on github ("v1.0" or newer) requires specific (bit older) version of gym. See requirements.txt.

Edit: Also, Python 3.12 might not work with MineRL (not tested). I recommend trying older version like 3.10.

JohnCThroneberry commented 2 months ago

Reading the gymnasium documentation it appears the backwards compatibility of v0.26.3 might be able to fill in for older versions of gym. Is this something you know of being attempted?

I will try an older Python version as well.

Miffyli commented 2 months ago

Newer versions of gym (outside 0.23) do not work because they set some limits on how things should be done (e.g., some fields are read-only), and MineRL made use of that older freedom in the code, so it would require some changes to support newer Gym versions or even Gymnasium. I do not know of people who have tried this, but I would be happy to review a PR on this; however I would want to keep backwards compatibility with older Gym and existing research code :)
