ValueError: Failed to initialize Pyglet window with an OpenGL >= 3+ context.

[asurada404]

I tried to run the sample points demo.

points, sdf = sample_sdf_near_surface(mesh, number_of_points=250000)

I got some errors:

...
~/anaconda3/lib/python3.6/site-packages/pyrender/platforms/pyglet_platform.py in init_context(self)
     36                 'context. If you\'re logged in via SSH, ensure that you\'re '
     37                 'running your script with vglrun (i.e. VirtualGL). The '

     39             )
     40 

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 "'NoneType' object has no attribute 'setView_'"

Can anyone give me some help?

Same issue here. It occurs when using surface_point_method='scan' method. 'Sample' works fine.

I get this error when running on an Ubuntu machine without a server -- error is resolved if you run
import os; os.environ['PYOPENGL_PLATFORM'] = 'egl' as described in the README.

This also randomly happens on Windows for me
