How to install the pyOpenGL correctly

[zyj-2000]

Thanks for the great job. I have run the ./RTL/main.py and come across the fault:

Traceback (most recent call last):
File "RTL/main.py", line 162, in
scene = MonoPortScene(size=(256, 256))
File "/home/zyj/Projects/Digital_Human_Recons/MonoPort/RTL/scene.py", line 102, in init
create_opengl_context(size[0], size[1])
File "/home/zyj/Projects/Digital_Human_Recons/MonoPort/monoport/lib/render/gl/glcontext.py", line 43, in create_opengl_context
glutInit()
File "/home/zyj/.conda/envs/torchzyj/lib/python3.8/site-packages/OpenGL/GLUT/special.py", line 333, in glutInit
_base_glutInit( ctypes.byref(count), holder )

raise error.NullFunctionError(
OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling

I search the Internet for help and know it may be the incorrect installation of pyOpenGL. However, many solutions on the Internet are based on win_amd64 platform. I wonder how to install the pyOpenGL in Ubuntu18.04 correctly?
