using robosuite without opengl on linux server

[nutsintheshell]

I 'm using a linux server without opengl. when I runimport robosuite, the following error occurs:

`Traceback (most recent call last): File "/root/miniconda3/envs/tapnet/lib/python3.10/site-packages/OpenGL/platform/osmesa.py", line 22, in GL return ctypesloader.loadLibrary( File "/root/miniconda3/envs/tapnet/lib/python3.10/site-packages/OpenGL/platform/ctypesloader.py", line 45, in loadLibrary return dllType( name, mode ) File "/root/miniconda3/envs/tapnet/lib/python3.10/ctypes/init.py", line 374, in init self._handle = _dlopen(self._name, mode) OSError: ('OSMesa: cannot open shared object file: No such file or directory', 'OSMesa', None)

During handling of the above exception, another exception occurred:

I wonder if there is a way to solve the problem or if I can run robosuite without opengl(I don't need to visualize any image on server). thanks

You would need to install one of the GL packages (egl, osmesa, glx) for mujoco to run properly.
