import mujoco_py error! #715

Closed mhmd97z closed 2 years ago

I followed the README instructions and also added mujoco200 to ~/.mujoco/, but I'm receiving the following error when it comes to importing mujoco_py

i have same issue !

ruze00 commented 2 years ago 
sudo apt-get install libosmesa6-dev
sudo apt-get install patchelf

Honestly, with all the issues and missing docs I wonder if this has been put out by 3rd graders!

mhmd97z commented 2 years ago

Thanks, @ruze00 Moving on, now I have another error to deal with!

I haven't had that issue, but this discussion might help:

ruze00 commented 2 years ago

Also, I haven't tried this yet but if you're on Windows I hear a conda install is the way to go.
