If anyone else is facing this same issue. I tried reinstalling the metadrive to the latest version but the latest one requires some dependencies incompatible with older python version.

I met the same problem. Did you solve it?

[abastola0]

I met the same problem. Did you solve it?

nope i kinda moved away from this because i keep getting some more. I suspect this is because of dependency mismatch. Were you able to resolve?

[pengzhenghao]

Sorry it might be the version mismatch. I believe downgrade to old version where we ran the baselines experiment might help. I will clean up those issues when I’m free. CoPO/benchmarks/MetaDrive-0.2.5 at main · decisionforce/CoPOgithub.com在 2024年5月17日，13:47，Ashish Bastola ***@***.***> 写道： I met the same problem.

pip install metadrive-simulator== 0.4.2.3 will solve the problem,
but you need to modify the env_wrappers.py to let metadrive suport openai.gym, like:

from metadrive.envs.gym_wrapper import createGymWrapper
env = createGymWrapper(MetaDriveEnv)(config={"use_render": True}) # wrap the environme
