when I run demo/

[btdan]

when I use demo/demo.mp4 as input , the demo/demo_mot.py is well done and get the ideal result .But when I use a new mp4 video as input, this program goes error. And display as follow:
python demo/demo_mot.py configs/mot/deepsort/sort_faster-rcnn_fpn_4e_mot17-private.py --input demo/0dbdc35ab8fc73539b569ce5d8338cfd.mp4 --output afn.mp4

Can anyone be kind to tell me how to solve this problem? Thanks very much.

Hi @btdan, this is because there is no output bounding box on your video, I will update the code to adapt this case.

@btdan fixed in #86, you can have a try again.

After I modify the code follow your suggestion, this program works very well. Thanks very much.
