unbuntu 20.04，errors about glutInit occur when I run the DeepMimic.py

[Ccarrotr]

When I run DeepMimic.py, errors came out like this:OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling.
I search online for the problem, but the answers are all about windows system, said that they should download 64-bit wheel for windows.But I didn't find the solution for linux. Hoping somebody can help me.
The details about the error is as follows:
Traceback (most recent call last): File "DeepMimic.py", line 314, in <module> main() File "DeepMimic.py", line 306, in main init_draw() File "DeepMimic.py", line 267, in init_draw glutInit() File "/home/liurui/anaconda3/envs/DeepMimic/lib/python3.7/site-packages/OpenGL/GLUT/special.py", line 333, in glutInit _base_glutInit( ctypes.byref(count), holder ) File "/home/liurui/anaconda3/envs/DeepMimic/lib/python3.7/site-packages/OpenGL/platform/baseplatform.py", line 425, in __call__ self.__name__, self.__name__, OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling

I solved this problem by installing the following library package:sudo apt-get install python3-opengl, I guess the reason is that my opengl environment was not complete before.
