performance hint: /home/zhang/miniconda3/envs/DecisionMamba/lib/python3.9/site-packages/mujoco_py/cymj.pyx:67:5: Exception check on 'c_warning_callback' will always require the GIL to be acquired.
Possible solutions:
1. Declare 'c_warning_callback' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
2. Use an 'int' return type on 'c_warning_callback' to allow an error code to be returned.

I had a similar Cython problem when I was using an older python version. Try to upgrade python to >=3.11
