opencv-python：haveOpenCL返回False

Question

Should return True if the the prebuilt binaries are compiled with OpenCL support. I've seen many examples where it just works out of the box. So my assumption is that the binaries are built with OpenCL support. So why might it not be working for me?

Also it works from C++ for OpenCV installed from source. So my computer has OpenCV runtime installed:

[ INFO:0] Initialize OpenCL runtime...

opencv-python version: 3.4.2

Answer 1

Stupid mistake.

Turns out I've been using the cv2 from anaconda. There I get:

Use Cuda: NO

Use OpenCL: NO

When using cv2 from opencv-python I get:

OpenCL: YES (no extra features)

Include path: NO

Link libraries: -framework OpenCL
