ImportError ProcgenEnv

[nforsg]

Hey,

I am working with this awesome library, but have encountered a wierd error that I have been unable to solve when running the ppg_procgen.py file.

I get the error: "ImportError: cannot import name 'ProcgenEnv' from 'procgen'", when running the script, which means that probably there is some kind of a bug in the source code for procgen benchmark right? I.e the have managed to make like a circular import entangelement or similar. Have anyone managed to run the code without this error? I would be very thankful if you could give me any hints of what this problem might depend on. The installation goes completely fine on python 3.12.1.

Have you downloaded procgen? Just run from procgen import ProcgenEnv in a python terminal

Yes I have. I am using Python 3.12

As procgen is completely unrelated to cleanrl, then there shouldn't be any issues
