demo.py opengl errors

[aespielberg]

Hi,

Thank you for the project, it's very exciting! I'm trying to run the demo, but I am getting a weird opengl error. I tried use_opendr, but the output was just two images: one was the input image, and the other was just a black square. I presume this means opendr is not happy either, even though opendr doesn't throw an error.

Looking through the other issues, I have tried the fix here; this did not change the output AFAICT.

I got it working. The fix was here
