pyglet error

[JonathanLehner]

I tried to run pyrender on the Leonard cluster at ETH Zurich. https://scicomp.ethz.ch/wiki/Leonhard_applications_and_libraries

I get the following error:

File "/cluster/home/lehnerj/.local/share/virtualenvs/wearable3dhandreconstruction--fu_gjdO/lib/python3.6/site-packages/pyglet/init.py", line 351, in getattr return getattr(self._module, name) AttributeError: 'NoneType' object has no attribute 'Window'

During handling of the above exception, another exception occurred:

will try loading mesa-glu/9.0.0

Try sudo apt install freeglut3-dev.

Hey @JonathanLehner,

How did you resolve this issue on Leonhard? I work on another project, yet I couldn't find how to run the code that uses OpenGL on server. I loaded ftgl/2.1.3 module (which also includes mesa/12.0.3 and mesa-glu/9.0.0), but it didn't help.

Trying to run the script normally gives this error

ValueError: Failed to initialize Pyglet window with an OpenGL >= 3+ context. If you're logged in via SSH, ensure that you're running your script with vglrun (i.e. VirtualGL). The internal error message was "Cannot connect to "None""

and prepending PYOPENGL_PLATFORM=osmesa to the python command gives

ImportError: ('Unable to load OpenGL library', 'OSMesa: cannot open shared object file: No such file or directory', 'OSMesa', None)

I would be really happy to hear your comment. Cheers.

I am experiencing the same issue as @dcetin described above.

Fix for me: sudo apt-get install libosmesa6-dev

On Arch linux I installed python-opengl and freeglut but was still getting this error. Installing the package glu fixed the problem for me -

sudo pacman -S freeglut python-opengl glu
