fail to run demo_video.py

[zxie-bdai]

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...

if(isinstance(list_of_frames[0], str)):
IndexError: list index out of range

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: #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?
