I installed the mesa utilities with the following command in the docker file:

RUN apt-get install -y libgl1-mesa-dev freeglut3-dev mesa-common-dev

but I am getting the error:

from OpenGL.raw.GL import _errors File "/usr/local/lib/python3.9/site-packages/OpenGL/raw/GL/_errors.py", line 4, in <module> _error_checker = _ErrorChecker( _p, _p.GL.glGetError ) AttributeError: 'NoneType' object has no attribute 'glGetError'

is there something I am missing, maybe a neccessary version? This code is right after the OpenGL import

os.environ['PYOPENGL_PLATFORM'] = "osmesa"
os.environ['MESA_GL_VERSION_OVERRIDE'] = "3.3"
from OpenGL import GL, osmesa

Am I installing mesa or opengl correctly on the docker container? if not how can I install it?

Have you tried xvfb – Head Wizard Locke Aug 25 '23 at 20:00
can you please elaborate some more? I am new to this – AynonT Aug 25 '23 at 20:33
xvfb creates a virtual framebuffer, aka a fake monitor that is really just a file, vfb is "virtual framebuffer" https://github.com/solarkennedy/wine-x11-novnc-docker/issues/13 for example – Head Wizard Locke Aug 25 '23 at 20:51
