AssertionError: Ground truth has 0 videos, BuT got 107 detected videos!

[LeoGeralt]

When I used the shanghaitech dataset for training, I found that the original training dataset was a video file, so I performed a frame extraction operation, but I still couldn't reach the 274514 training frames mentioned in your paper. In addition, when I used the shanghaitech.pth file you provided for testing, the following error occurred: AssertionError: Ground truth has 0 videos, BuT got 107 detected videos! I suspect it's an issue with the dataset, as the shanghaitech dataset does not have files similar to ped2. mat like ped2. I hope you can answer my questions. Thank you.
