AttributeError: property 'shape of 'Discrete' object has no setter

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]

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]

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 :)
