maybe something about the version of cython

[kobeap]

the problem at the beginning:
File "/home/loc/anaconda3/envs/rl3d-1/lib/python3.8/site-packages/Cython/Build/Dependencies.py", line 1321, in cythonize_one
raise CompileError(None, pyx_file)
Cython.Compiler.Errors.CompileError: /home/loc/anaconda3/envs/rl3d-1/lib/python3.8/site-packages/mujoco_py/cymj.pyx
then i change the version of cython,then other problems arise
and run bash script/train.py:
Compiling /home/loc/anaconda3/envs/rl3d-1/lib/python3.8/site-packages/mujoco_py/cymj.pyx because it changed.
[1/1] Cythonizing /home/loc/anaconda3/envs/rl3d-1/lib/python3.8/site-packages/mujoco_py/cymj.pyx

compilation terminated.

Hi,
what is the cython version you are using?

maybe try this.

pip install Cython==0.29.35

not sure whether this helps, but it helps in a lot of scenarios
