fail to run demo_video.py

[zhaomingBDAI]

Hi,

I am trying to run the demo code with

python demo_video.py --input_video example_data/videos/breakdancing.mp4 --out_folder demo_out/videos

But I got the following error:

[2024-03-25 17:39:30,875][phalp.trackers.PHALP][INFO] - Setting up Visualizer... [2024-03-25 17:39:31,824][phalp.trackers.PHALP][INFO] - Setting up DeepSort...

Any help is appreciated! Thanks.

There seems to be an issue when loading the extracted frames from the input video. Can you check the content of list_of_frames?

Hi, I have the same error, and yes the list_of_frames return empty. How can I fix it? By the way, I had also an import error related to neural_renderer. I fixed it by changing the line

phalp_tracker = HMR2_4dhuman(cfg)

phalp_tracker = PHALP_Prime_HMR2(cfg)

as explained here: https://github.com/statho/ScoreHMR/issues/7

Did anyone find a fix for this?

Probably the frames from the video are not extracted or extracted in the wrong directory, that is why list_of_frames is empty. For the provided video, the extracted frames should be in demo_out/videos/images/breakdancing/. Can you verify that the images are indeed extracted in that directory?
