I am reproducing the code of safety-starter-agents. To fulfill the requirements in the setup.py file, I am running the code in a virtual environment on which python3.7 is running. This python version is compatible with all required packages versions.
In particular, I downloaded the required MuJoCo 2.0.2.7 from here. I added the mjkey.txt to the ~/.mujoco directory. I added the EXPORT-path to the ~/.bashrc following this tutorial
I am running the code on WSL Ubuntu 24.04.
When I run pip install mujoco_py==2.0.2.7, I am getting the following error:
Building wheels for collected packages: mujoco_pyBuilding wheel for mujoco_py (pyproject.toml) ... errorerror: subprocess-exited-with-error

However, changing Cython versions is not working in this specific setting.
I was able to successfully download other versions of MuJoCo on this same virtual environment. MuJoCo 2.0.2.7 is delivering this error.
Does anyone have an idea how to resolve this error?
