when I run demo_mot

[Moens007]

I take a video as input and start reporting errors when it runs to frame 3527:
python demo/demo_mot.py configs/mot/tracktor/tracktor_faster-rcnn_r50_fpn_4e_mot17-private.py --input /media/moens/Moens/Dataset/school-vedio/01.avi --checkpoint checkpoint/faster-rcnn_r50_fpn_4e_mot17-ffa52ae7\ (1).pth --fps 30 --output mot1.mp4 --show

cv2.error: OpenCV(4.5.1) /tmp/pip-req-build-7m_g9lbm/opencv/modules/video/src/ecc.cpp:572: error: (-7:Iterations do not converge) The algorithm stopped before its convergence. The correlation is going to be minimized. Images may be uncorrelated or non-overlapped in function 'findTransformECC'

Can anyone be kind to tell me how to solve this problem?I don't know if it's the problem of my video.
Thanks very much.

As we do not have the video that cannot directly debug for you.

Can you try to figure out where is the bug from and report it here?

I had the same error when running on videos like EYy1NKyjvlo_000102_000112.mp4 from kinetics test set. There is obviously no correct alignment for those frames, but as a workaround to stop the script from crashing I added try/catch around the findTransformECC function.

you should try opencv-python3.4.x

you should try opencv-python3.4.x

May I ask, why this can solve the issue above?
