I add the "from evaluation.eval_mil_reach import EvalMilReach" to the main_mil.py and the question is slove,i don't know if this is the right thing to do.But now a new error occur:

I have made a mistake that i didn't switch to the mil.When i switch to the mil ,the error above is sloved.But now i meet a new question,like this:

(HINT: you need to install mujoco_py, and also perform the setup instructions here: https://github.com/openai/mujoco-py/.)

I have been searching for a long time and have not found a solution.How can I solve the problem? Thanks!

When i use gym's branch mil ,the version of gym is 0.9.3 and the mujoco version 131,mujoco_py version is 0.5.7.The problem is sloved.

Hey @suqianxin -- I'm trying to get this to work ; I have got the right mujoco and mujoco_py, but it still doesn't work. I don't understand why you need to install gym to a specific version, don't we just need to use tianheyu's gym @ mil branch (and @stepjam says this doesn't need to be installed, it can just be on the pythonpath). Please advise exactly what you did if you have a moment, it will help a lot.

For reference, I am getting this error:

Further investigation leads to deep changes made within Python itself on how it handles some C stuff: In order to correct this bug: https://bugs.python.org/issue16575 They made this change: https://github.com/python/cpython/commit/79d4ed102a5069c6cebaed2627cb1645637f0429#diff-998bfefaefe2ab83d5f523e18f158fa4 That has broken a lot stuff in Python 3.7.6 -- 3.8.1. Apparently it will be fixed in 3.8.2, but I don't know. Examples of stuff it has broken: https://github.com/davidjamesca/ctypesgen/issues/77 https://github.com/pyglet/pyglet/issues/112
