It looks like there is an error in unit tests, which is not shown while testing locally.

@guarin, do you know what could be the reason?

[guarin]

Not sure, would have to investigate. The error doesn't give a lot details. I restarted the run now to see if it is reproducible.

@guarin, can I help somehow to resolve this?

[guarin]

I am honestly not sure what the problem is and I sadly don't have time to reproduce it right now. At least in CI it is reproducible so there is something wrong. The only small thing I saw is that the frames_over_videos are in (T, W, H, C) format instead of (T, H, W, C) but this shouldn't trigger the error.

Did you run your local tests with the same Python and Torchvision version as in CI?

@guarin, I've resolved the issue, please check. The problem was with video format.
