What happens if there are no detections in a frame

[towardsautonomy]

I am wondering what happens if there are no detections in a frame. In that case I will be calling the update function with the following:

dets_all = {'dets': [], 'info': []}

It throws an error because it is trying to extract info from an empty list: dets = dets[:, self.reorder]

How should empty detection be handled?

That should never happen, as its only reading the detections from the text file, so if there are no detections in a frame, it wont just never read it.

It is weird that, on my side, my code can handle the empty list when executing dets = dets[:, self.reorder].

Could you please provide the detailed error message so that I can help.
