cv2.error about bot-sort HOT 5 CLOSED

Thanks @NirAharon , this is almost exactly what i ended up doing too. Appreciate your quick help.

BotSORT has been quite a nice improvement for me on challenging sports tracking cases. Thank you for the great tech!

Hi, please try to use the demo.py I uploaded today.
Please let me know if errors occur.

from bot-sort.

In code just pulled right now, seeing same error after a few hundred frames of tracking successfully.

I found out that for cmc-method with ORB flag, the OpenCV function estimateAffinePartial2D could get too few matching points, which lead to an error.
I just updated the gmc.py code.
Thank you for your help.

Hi @NirAharon , I just clone new code today, when demo I keep getting the same error. Can anyone help me figure out why?
