The app can't find any face in the photo

leonardoa

Hi @Andrey I have the latest update of the app and noticed that it wasn’t detecting the faces on the latest albums I added to the library. First I manaully forced rescan of the folder. Next, I clicked on the face and tell it to detect faces but it keeps saying no face found.

What am I doing wrong? It’s not just this photo but happens on all photos in which I asked the app to detect a face inside the photo by right-clicking on the face.

Andrey

leonardoa do you use CUDA? What version number is shown in About dialog, does it say CUDA?

I guess you need to make debug logs so we can see if there are any errors: https://community.tonfotos.com/d/26-making-debug-logs-in-tonfotos

I’m running 1.74 (cuda) on my Windows laptop.

I sent the log file via support email.

Cheers

leonardoa Thank you for sharing logs. Here’s the interesting part:

There is something wrong with CUDA compatibility on your device. How many GPU’s do you have? What are the models?

The simple workarround would be just to remove Tonfotos CUDA plugin to get back to CPU processing. However, if you can share any details about your setup, that would be very useful information for me.

leonardoa

OK. This is my laptop spec.

I don’t know who many GPU it has but this is a link to the spec sheet

Hope this helps.

Andrey

leonardoa Thank you that helps. For some reason Tonfotos has issues with 3xxx series much more than with any other. In any case, this is very useful information, thank you!

Did you manage to switch to CPU processing? Is everything OK now?

leonardoa

Yes, I uninstalled the CUDA and I was able to manually tag a face. But auto face detection is not detecting these faces in my latest set of albums yet. I selected Rescan Folder on each of these folders but nothing has come up on face suggestions.
I can see on the status bar at the bottom is the app is scanning other folders but once it’s completed most of the new photos still have no face tags/suggestions.

Andrey

leonardoa Rescan folder will not do the trick, it only looks for changes in the folder. You need to do “Re-index files(s)”, that will force application to index files from the scratch, including looking for faces again.

leonardoa

How do you manually trigger reindexing of a particular folder? If I right-click on a folder I can only find ‘Stop indexing <folder name>’.

Over the last couple of days, I let the app running and I can see that it was indexing folders (based on the activity on the status bar in the bottom of the app) until the process finished. I then checked for faces in the folders and no new faces have been detected.

Andrey

leonardoa How do you manually trigger reindexing of a particular folder?

This command is not folder-based, it is files-based. You need to open folder, then select all files inside, and then right click on one, you will see this command.
