Mujoco installation, binaries not found


I'm in trouble for installing mujoco.

I folows the steps at https://github.com/openai/mujoco-py/issues/253.

Everything worked correctly, but when I had to run "python examples\body_interaction.py" I'm having an issue :

Traceback (most recent call last):
  File "D:\Session User\Desktop\computing\stage2021_hedwinb\mujoco-py\examples\body_interaction.py", line 10, in <module>

    raise error.MujocoDependencyError('Found your MuJoCo license key but not binaries. Please put your binaries into ~/.mujoco/mjpro131 or set MUJOCO_PY_MJPRO_PATH. Follow the instructions on https://github.com/openai/mujoco-py for

This is how my .mujoco directory looks like:

And mujoco200 is the directory i downloaded from there: https://www.roboti.us/index.html for win64,

This is how my Env variables looks like:

To solve this, I tried to download "mjpro131 win64" from there, and add it to the env. variables using name "MUJOCO_PY_MJPRO_PATH", but then it gave me an other error:

    self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 n’est pas une application Win32 valide 

Last line translation:

OSError: [WinError 193] %1 Is not a valid win32 application.

I Also tried with the win32 achive, but it gave me the exact same error.


Solution

  • I had the same problem in Linux. I decided to download the 0.5.7 version of mujoco

    pip install mujoco-py==0.5.7
    

    and then changed the requirements to

    click==7.0
    xmltodict==0.12.0
    scipy==1.3.1
    gym==0.10.8
    jsonnet==0.11.2
    numpy
    mujoco-py==0.5.7
