I've tried to run the example for Orbit using SKRL, I have created a new conda environment via orbit and this issue still persists...any fixes ???

I'm getting this issue while importing SKRL

Hi @1412kauti

It seems to be a gymnasium error.

Which version do you have installed? Run the following command to get it

orbit -p -m pip show gymnasium

I have gymnasium v0.27.1 and the import works. You can install this version via:

orbit -p -m pip install gymnasium==0.27.1

Turns out that I had to update gym, gymnasium and importlib_metadata

pip install --upgrade importlib_metadata
pip install --upgrade gymnasium
pip install --upgrade gym

cuz I tried to replicate the issue in another machine and I stumbled on the same errors in a different order

Got it fixed .... Thanx
