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. digikam version 5.4.0 Images: GIF: 60 JPG: 5684 RAW-NEF: 8751 total: 14495 : Videos: MP4: 10 total: 10 : Audio: MP3: 3099 WAV: 2 WMA: 355 total: 3456 : Total Items: 17961 Albums: 636 Tags: 26 : Database backend: QSQLITE Database Path: C:/Users/Struan/Pictures/
Install DebugView tool from Microsoft and when you run Face detection, report here all debug trace printed by digiKam. Gilles Caulier
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

I'm concluding this from: "... 00000010 13.10399723 [9788] digikam.facesengine: Face database ready for use 00000011 13.12266350 [9788] digikam.general: Face PipeLine: add preview thread >00000012 13.12278080 [9788] digikam.general: Face PipeLine: add single thread detector >00000013 13.12292194 [9788] digikam.general: Face PipeLine: add recognition worker 00000014 13.12304497 [9788] digikam.general: Face PipeLine: add database writer ..." 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. Gilles
This problem still reproducible with current 5.8.0 - pre-release Windows bundle available here : https://files.kde.org/digikam/ Gilles Caulier
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: https://files.kde.org/digikam/ Gilles Caulier
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... Gilles Caulier
