Did you solve this problem?

Hello there,
I have tried modify diffuser/environments/registration.py, in which I added following code in ENVIRONMENT_SPECS=
{ 'id':'halfcheetah-medium-expert-v2', 'entry_point':('diffuser.environments.half_cheetah:HalfCheetahFullObsEnv'), },
This solved the problem of "No registered env with id: halfcheetah-medium-expert-v2".

However, when I run plan_guided.py again, it comes out with new error.
AttributeError: attempted to get missing private attribute '_max_episode_steps'

I hope this method could be helpful to this problem, and also hope someone could fix the new error.
