Hi,

When I have run the following workflow:
Extract (batch, identity)
Sort (batch, face, face)
Manual cleanup of folders
Move desired PNGs to the parent folder
Alignment (remove-faces)

I end up with the following error:

Traceback (most recent call last):

Please let me know if you need any additional information to debug the issue.

Thanks a bunch

Hmmmm, I thought this bug had been fixed, so it must be quite edge-case at this point (I recently ran extraction, with a very similar workflow to yours, over hundreds of videos).

As I'm unlikely to be able to fix this without being able to recreate, would it be possible for you to repeat the process, then zip up the faces folder + original alignments file and provide to me in their state just before running 'remove-faces' so I can recreate and look to implement a fix.

Sure thing. I've uploaded the requested files here:

Ok, the reason you are hitting this error is that it looks like you have moved faces out of the aligner filter folders and into your main folder. You cannot do this. Faces which have been filtered out do not exist in the alignments file, hence when the process tries to remove the face from the alignments file, it can't find it and you hit an error.

If you want to keep some faces from the filtered out folder, you will need to regenerate an alignments file. You can do this by having all the faces you want to keep in a single folder and run the alignment tool from-faces job.

It's worth noting that faces which have been filtered out but look ok, probably have bad landmarks, and by chance happen to look correct visually.
