Hi,

Most probably your face detector did not detect any faces in the image.

Hi,

Did you pass the below and do you have the same folder structure as below:

parser.add_argument("-k", "--known_user", type=str, default=None, help="Folder containing user images data") parser.add_argument("-K", "--known_user_force", type=str, default=None, help="Folder containing user images data, force reload")

Your command should be: !python video_test.py -m checkpoints/GN_W0.5_S2_ArcFace_epoch16.h5 -k path/to/know_user_images

The folder structure should be:

images -- 1 -- -- image1.jpg -- -- image2.jpg -- -- etc

Try and let me know

Yes, thanks for your attention, after posting issue I figured out this !
