Description Struan Lownie 2017-02-03 11:12:35 UTC

I recently installed DigiKam and having added the folder from my NAS containing all of my images into my collection I navigated to Faces and clicked "Scan collection for faces" apon clicking OK I get about 30 seconds of activity and the progress bar progresses to 100% however no new faces are detected.

I have also tried specifying specific individual folders and see very similar results (progress bar finishes faster for small folders)

Below are my current database statistics, I would expect face detection for this number of photos to take several hours.

Install DebugView tool from Microsoft and when you run Face detection, report here all debug trace printed by digiKam.

Created attachment 103793 [details]
Debug as requested.

Debug log starts when DigiKam had finished loading, and saved once the Facedetection reported itself to be finished (5 seconds after start)

I was running Facedetection against a folder containing 8.48GB of NEF files, 609 images

Acording to your log, it seems that you chose detect and recognise as option.
I'm concluding this from:

"...

This problem was already solved in this bug:
https://bugs.kde.org/show_bug.cgi?id=375375

So, this is a known bug in 5.4 which is fixed for the upcoming release 5.5, I woud say.

Seems to me like a duplicate, Gilles.

Struan,
can you test with the current 5.5 pre-release for Windows which is located here:

https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM

Should be fixed.

Maria,

It can be a duplicate, but already fixed bug is for Linux, this one is for Windows. So, we must considered not as a duplicate for the moment.

Struan,

The 6.1.0 pre-release installer have been updated this morning. Please test and
report to see if you can reproduce the dysfunction:

Comment 7 caulier.gilles 2019-12-23 14:20:16 UTC

With 7.0.0-beta1, we drop all Dlib deep learning code in digiKam in favor of
OpenCV Neural Network

https://download.kde.org/unstable/digikam/

This problem is not reproducible...
