Hi when I run the command python scripts/run_meva_on_video.py --cfg train_meva_2 --vid_file zen_talking_phone.mp4 --output_folder results/output --exp train_meva_2 I get the error below:

Looks like the inference code did run but it failed during rendering. The estimation results should be at "Saving output results to "results/output/zen_talking_phone/vibe_output.pkl"". Looks like your pyrender is throwing errors?

[melih-unsal]

Thanks for your fast reply. Is it like a version incompatibility of pyrenderer?
