Digikam-3.4.0 crashes frequently - face recognition/detection

[Mike Booth]

I have spent hours manually tagging photos in Digikam whilst waiting for face r/d to arrive.

 

I find this part of DG incredibly unstable/unreliable although I am impressed with rest of it.

 

I've include console output of the latest crashes ( means nothing to me) and also output of the " Components Inf" dialog.

 

 

Also "Unknown" has about 3800 pictures in it and I have 40 tags.

 

 

Console Output

 

digikam

 

QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.

 

terminate called after throwing an instance of 'DJVU::GException'

 

QSocketNotifier: Invalid socket 7 and type 'Read', disabling...

 

QSocketNotifier: Invalid socket 10 and type 'Read', disabling...

 

digikam: Fatal IO error: client killed

 

KCrash: Application 'digikam' crashing...

 

KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit

Hi Mike,

I also experience problems while using face detection/recognition. I
am not really sure, but I have a clue that the sqlite-database used by
libkface (it is located in
.kde4/share/apps/libkface/database/recognition.db) might be
responsible for this. libkface stores its training data there. When
digikam crashes while tagging faces the data seems to be rebuilt
within the same database when digikam is run the next time - the
database doubles its file size. So, from time to time I delete it and
I rebuild the training data again by choosing the corresponding option
within digikam.

Currently, I am facing another strange behaviour - whenever I choose
the face detection/recognition pane digikam becomes incredibly slow.
htop then tells me that there is one digikam thread consuming 100% cpu
on one core. But up to now, I did not have time to have a closer look
here.

Ciao, Fabian

Hi Fabian- Thanks for the tips. I managed to get through a recognition
excercise on all of my "unknowns" by following them.
Like you though performance is really slow when opening a "tag" folder, or
moving from thumbnail to preview and back again.

I also have the strange behaviour that a thread uses most of the CPU. It seems
to be related to mouse movement and happens when you 'hover ' over a different
tag.

It also happens on album folders but not  to the same degree.

You might be able to confirm this behaviour to help in the fixing of it

yep, I was observing exactly the same behaviour. I guess this was
caused by some mismatch of digikam-, kde- and qt4-packages on my
system (I am currently running openSUSE 12.3 with KDE 4.11 from the
OBS). After updating these packages the face recognition/detection
pane seems to be as responsive as it should be.

Ciao, Fabian
