Question: which branch of mujoco-py and version of mujoco product you using

[huangjiancong1]

Hello,@RussellM2020, i have met some error when combining the training env, and want to ask you some questions:
The Mujoco software version: 131? 150? 200? It seems that only 150 can run the multiworld env.
