Error: 'No humans in first frame' for provided examples

[Kamlesh364]

I'm running the demo app implemented in Gardio. I am using the given examples only as input files but it works only on images and not on videos.

Terminal errors are as following-

Hi, the demo requires the first frame to have visible people. There may be some problems with the human segmentation model that cannot detect people. I cannot fix it right now due to a deadline coming up. I will fix it later.
