unable to load numpy_formathandler accelerator from OpenGL_accelerate

[Joonghyuk Shin]

Hi, currently testing the code with sample data but there seems to be an error loading numpy_formathandler accelerator.
After calling python viewer.py --config downloads/person_1.yaml --viewport 2000,1328 --origin-view, the view.py window freezes with above error.
I can't figure out what's wrong here. Any idea?
Thanks!

Actually we have the same debug message when running viewer.py, but it does not affect the rendering. The viewer is still able to run successfully with this message. Try to press the "Wait" button and to see if it helps. ср, 30 дек. 2020 г., 22:23 alex4727 <[e-mail]>:

I'm currently using Nvidia rtx 3070 graphics card which is known to have similar performance compared to RTX2080 which is at least a bit better than recommended gpu (1080ti). How long does it take for typical gpu to work on this sample dataset?

For the "person1" dataset and ~FullHD resolution, viewer.py operates at ~4 FPS on 1080ti on my end. Do you observe worse performance? If FPS is low, decreasing resolution in --viewport should help.
