OpenGL.error.Error: Attempt to retrieve context when no valid context

I'm running this on an ubuntu laptop with an intel CPU, no GPU and the corresponding cuda-less version of torch. I got a similar error on Windows, but I saw from another issue that rendering isn't supported on Windows yet. On windows no window opened but on linux a black window opens. The opengl context is definitely there.

It looks like the error is on another thread, as the program keeps running. If I had to guess it looks like the OpenGL context isn't visible to whatever thread is giving this message.
(pressing ctrl+c gives the standard KeyboardInterrupt message)

The OpenGl method in question is this one:

glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, FLOAT_SZ * 3, ctypes.c_void_p(0))

Upgrading PyOpenGL PyOpenGL_accelerate and pyrender fixed this, but I have the same issue as #227 now

Maybe add the correct version of these packages to the requirements?

The solution from #227 also fixed my issue here (tested on a fresh virtualenv)
