Error in running run.sh - attempt to perform arithmetic on field 'scale_factor' (a nil value)

[shreelock]

Found the following error while running the script. The script fails at passing cropped image through the VRN. I tried using one image at a time as well, but not able to figure out why is the code failing. It looks like its failing at image.scale, but there's no scale_factor field reqd for image.scale.

Do you have any insight as to why this is happening?

When did you install Torch? If old, can you try a newer version please?

[shreelock]

Thanks a lot Aaron, initially I had a lot of trouble installing dependencies for running vrn code, but then I used the facealignment docker image provided by adrian, which already had everything installed, except that it had the older torch version. I have updated torch and the flow works flawlessly.

Thanks a lot, and Merry Christmas! :)

Excellent :) :christmas_tree: Merry Christmas.
