guix package / build instructions for digikam
I recently updated to 8.7.0, and am trying to rebuild my face recognition
database, this is painstakingly slow. Previously, this would take a few hours
at most, but after leaving it running overnight it's still at 0%.
STEPS TO REPRODUCE
I don't know exactly how to reproduce it, but i've attached the Guix build
specifications I've used to build it. If you have a recent gnu guix available
running `guix shell -f digikam.scm -- digikam` should build and run digikam,
after which one can rebuild the face recognition database via tools/management
OBSERVED RESULT
The progress bar for the face recognition database rebuild is still at 0% after
running for 15 hours.
I've manually taken a look at what happens to the recognition database, and it
seems like digikam is (very) slowly adding entries to the FaceMatrices table -
after running for 15 hours, it has 11k entries, whereas I've tagged 30k faces,
so I expect that this would take at least another full day.
EXPECTED RESULT
Face recognition database is rebuilt within a reasonable amount of time
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Running on Guix
KDE Plasma Version: ?
KDE Frameworks Version: 5.116.0
Qt Version: 5.15.15
ADDITIONAL INFORMATION
I'm on a 13th gen intel i5-1340P with 32GB of ram, so I wouldn't expect this to
be caused by insufficient system specs.
