meet problem when running demo for video

[Xulei-Zhai]

when i run the commend as follows：

python demo.py tracking,ddd --load_model ../models/nuScenes_3Dtracking.pth --dataset nuscenes --pre_hm --track_thresh 0.1 --demo ../videos/nuscenes_mini.mp4 --test_focal_length 633

i met this problem:

python demo.py tracking,ddd --load_model ../models/nuScenes_3Dtracking.pth --dataset nuscenes --pre_hm --track_thresh 0.1 --demo ../videos/nuscenes_mini.mp4 --test_focal_length 633

Encountered the same, have you solved it already? Thanks in advance :)

@Xulei-Zhai hi， have you solved this problem? met the same problem. Thanks

[morrolinux]

That's due to the wrong version of OpenCV being installed. I solved with pip install opencv-python==3.3.1.11 (do this from inside the conda environment)

[Xulei-Zhai]

@morrolinux I solved the problem through your method, thank you very much.
