Issues of installation caused by gym's vision.

[SecretaryofSFA]

I have installed the gym==0.19.0 and there is a error about the conflict between the copo==0.0.0 and ray[rllib]==2.2.0.
The error just is like this:
"
The conflict is caused by:
copo 0.0.0 depends on gym==0.19.0
ray[rllib] 2.2.0 depends on gym<0.24.0 and >=0.21.0; extra == "rllib"
"

I have tried to uninstall the ray==2.2.0 but there were still this error... How can I solve this problem?

or could I change the code in setup.py? I'm afraid that it would cause more confusing bugs..

I changed the 'gym==0.19.0' to 'gym>=0.19.0' in setup.py then copo was installed successfully.

But I met another problem which is ''pickle5.pickle.PicklingError: Could not pickle object as excessively deep recursion required.'' when I ran the ''python./copo_code/copo/torch_copo/train_copo.py''

By the way, I just could install the metadrive-simulator==0.2.5.1 because I didn't find the 0.2.5 vision even using ''pip install git+https://github.com/metadriverse/metadrive.git@releases/0.2.5''

I'm now encountering a similar problem. Have you managed to resolve it?
