--- Comment #11 from [email protected] --- Hello Just some words to tell you everything is now ok : - first, I changed OPENCV_OPENCL_DEVICE` system environment variable to `:GPU:0` only. - then I activated openCL on Digikam and restarted it. - I tested the OPenCL in Digikam and the test found openCL correctly. - I downloaded again all models needed using the Digikam interface and restarted. - After this operation, I was able to use the face tag and the face search engine without any crash !! Thanks a lot again for your help !! regards Philippe Bezard-Falgas Le lun. 14 sept. 2026 à 18:36, Philippe Bezard-Falgas < [email protected]> a écrit : > Hello > > I realized I was using a NVIDIA GEFORCE RTX 2080 SUPER, so I followed the > documentation : > > For NVIDIA GPU users (e.g., GeForce RTX 2070 Super, RTX 3060 Ti, etc.), > additional steps are required to ensure successful GPU detection by > OpenCV’s AI backend.
