Description CM 2025-11-01 21:57:19 UTC

I'm trying to text OpenCL Hardware Acceleration for Face Detection, but getting this:

Starting OpenCV OpenCL DNN test...
Checking for OpenCL GPU acceleration compatibility with AI models...
Error: OpenCL is not available on this system.

Test failed. Your system may not be able to use GPU acceleration for the AI models.

Comment 1 caulier.gilles 2025-12-10 16:52:51 UTC

During Christmas time, i will rebuild the whole digiKam installer from scratch
with VCPKG packages updated (opencv, qt, ffmpeg). We will see if the problem
remain.
