Recently discovered Tonfotos and already fan of it ! A’m currently using the Free version 1.11.17 (cuda) on Win10 ×64 but will upgrade soon. I sucessfully ta...

Face recognition not available anymore

Didier

Thank you Andrey for your quick response.
pCloud works very much like Dropbox, with an appication running on Windows for accessing the files from the cloud.
This means that the files always have the same path as it was a local path.
The images can till be shown from the “Folder” tab and from the “Locations” tab, as well as all metadata (unless faces)

I also tried to deselect / reselect the “Recognize faces” buton from the Library management window.

Andrey

Didier Thank you, it looks that my initial guess was wrong. If files are still there and you can still open every file to view fullscreen, then there should be something else.

Do I get right, that when you select a photo, you don’t see any face on it (in the file info panel)? Not just people, but unassigned faces are also missing? If you do “re-index photo”, will faces appear again?

Didier

indeed, by selecting a photo, I don’t see any metadata about face in the info pannel, nor any way to confirm a person, since nothing is suggested.
I tried to Re-index some files from the context menu, but nothing changes.
I also tried to deselect and reselect the Recognize faces from the Library without success.

Andrey

Didier Ok, interesting. What happens if you open the photo and then try to add face manually?

Didier

when “Add new face at this location” from context menu, it says "Could not find a new person’s face in
the specified location."
But “Add to personal album to…” works, so then I can see this picture linked to the avatar in the info pannel.

Didier But “Add to personal album to…” works, so then I can see this picture linked to the avatar in the info pannel.

Yes, that part should always work, it does not depent on recognition.

Didier when “Add new face at this location” from context menu, it says "Could not find a new person’s face in
the specified location."

Is this clear picture with unobscured high quality face? That means that recognition does not work for some reason. Do you have CUDA Runtime installed? Let us start from removing it (when Tonfotos is closed). This will disable GPU processing and only CPU will be used. If that will not also resolve situation and faces will not be recognized even you do it manually, the next step should be logs: https://community.tonfotos.com/d/26-making-debug-logs-in-tonfotos

Didier

yes, by having uninstalled CUDA, the face recognition comes back…
So, would it be a bug in CUDA plugin? or should I try reinstalling it again ?

Andrey

Didier There are so many moving parts when it comes to recognition on GPU, there is GPU itself, NVidia drivers, CUDA library, etc. Who knows at which stage it went wrong, this is really hard to say.

I would suggest you continue without CUDA if it proven to be unstable on your system. It is only needed when you index your library, it helps to speedup the process. Afterwards you will not even notice the difference in performance.

Didier

Alright, understood.
Thank you for your support !

Andrey

Didier Sure, thank you for the patience with all my questions.

By the way, if you like the program please consider rating it on Trustpilot

Didier

While the Face recognition went back by uninstalling CUDA, poeple who where previoulsy indexed do not appear anymore, but only works with new pictures.
Re-indexing these previous pictures desn’t help.
If I want to restart the recognition from scratch, would it be enough deleting all .tonfotos.ini files everywhere ?

Andrey

Didier If that is the way you chose, then

remove the folder from “Library locations”,
Remove all ini files
Add folder again
Wait for indexing to finish
