Description Michał Byrecki 2025-05-14 12:48:48 UTC 
I've been using digikam from Debian's package (old version) and made a decision to download latest app image.
On the first run it throw a message, that the AI CV face recognition data is outdated and the model needs to be re-learned, asking to initiate the process.
I've confirmed, but since the newer model has not been yet downloaded, it crashed:

Digikam::DNNFaceDetectorYuNet::loadModels: Face detection model: YuNet not loaded
Digikam::DNNFaceDetectorYuNet::DNNFaceDetectorYuNet: Failed to load YuNet model
terminate called after throwing an instance of 'QUnhandledException'
  what():  std::exception

So, before prompting for re-learning the model, the newer model has to be downloaded first.

Ah, I haven't been using pre-release, but 8.6.0. If the problem has been already addressed the bug can be closed.
