"assert len(arr) == framesize" throws an error

[Thaldos]

Hello,

I tried to run the command "python3 inference_video.py --exp=1 --video=video.mp4" on my own custom video, but I got the error :

[email protected] in /shared/httpd/arXiv2020-RIFE $ python3 inference_video.py --exp=1 --video=video.mp4

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    for frame in videogen:

    raise RuntimeError("%s" % (err1,))

Does anyone know the reason ? It seems to be about the "framesize", but I don't know what it is exactly :/

Thanks for your help

This error is caused because sk-video can not open your video successfully. Would you mind upload your video to Google drive and send it to me?
