Tonfotos fails to start after Python installed

bbonn

I recently installed Python 3.13 to work on some AI modeling for photo classification using Tensorflow. It didn’t work as 3.13 is not compatible. I installed Python 3.10 and it now connects. However, TonFotos no longer starts. I rebooted but it did not fix it. What are next steps? Do I reinstall? If so, do I need a new download with a new key?

For reference, I’m using a Windows 10 Pro 22H2 and my current version of Python is 2.10.11 apr 5 2023, msc v1929 64 bit

bbonn Can you please be more specific about symptoms? What exactly happens when you try to start Tonfotos? Any error message? Did it even try to start?

If it just silently fails, then please refer to this guide about how to start it from command line: https://community.tonfotos.com/d/26-making-debug-logs-in-tonfotos/2 This way you will able to see error messages, and based on that output we can decide what to do next and hopefully what is the reason.

sure thing. it just doesn’t launch - no errors, nothing (app or background process) that appears in the Task Manager from what I can see, no popup . here is the log file output…

Ups, that is bad… Looks like the internal database crashed. Any idea what happened? Hardware reset? App crash?

Anyway, the solution is still the same - you will need to uninstall and reinstall application back. This will trigger creating database from the scratch. Unfortunately, it will take time for full recognition of all your photos, but don’t worry all the work with faces will be fully restored - Tonfotos keeps this data not only in the internal database, but also in ini files right next to photos. Same with metadata editing - this information is stored inside photo files.

Please read this to better understand where Tonfotos stores its data: https://tonfotos.com/docs/library/setup/#data-files

Sorry that you had to face this issue and now will need to wait again until all images will be indexed again.
