Test GPU AI Compatibility:

and I'm missing the test image.

Starting OpenCV OpenCL DNN test...
Checking for OpenCL GPU acceleration compatibility with AI models...
OpenCL is available on this system.
OpenCL acceleration device is available.

Error: Test image not found.

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

What is the test image?

When I run ollama, I get:

I also run darktable and it works with opencl:
