mujoco-py problems #5

Open zichunxx opened 6 months ago

zichunxx commented 6 months ago

Hi! Thanks for your nice work.

I tried to install the dependencies following the README and created a conda env with python==3.8.

However, I met the following installation problems

Building wheels for collected packages: mujoco-py
  Building wheel for mujoco-py (pyproject.toml) ... error
  error: subprocess-exited-with-error

      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.

  note: This error originates from a subprocess, and is likely not a problem with pip.

Would you mind giving more specific instructions about your python env? Thanks in advance.

Hi! zichunxx, have you overcame this yet? I also encountered this error with python3.8 under ubuntu20.08. By using: pip install cython==3.0.0a10 the problem might solve.

Hi, @DJ-Won! Thanks for your kind help! I will try with your solution.
