Error: Frame count is not OK for video

[orenpapers]

I have the following code that is based on the example:
And I get the error:

Epoch 1/3
21/69 [========>.....................] - ETA: 54:24 - loss: 1.5353Frame count is not OK for video /content/drive/My Drive/videos/dataset/A/video7.avi, 2 total, 1 extracted

while fitting.
Any idea why?
Thanks!

This basically means the video does not contain those amount of frames. Navigate to that specific video file and you will find it out it does not have those frames. Usually, the video is either short or corrupt. Highly, likely corrupt!
Just delete that video and the error will go away.

That's a problem I want to resolve
