    NOTE:   your OpenCL library only supports OpenCL 1.0,
        but some installed platforms support OpenCL 1.2.
        Programs using 1.2 features may crash
        or behave unexpectedly

Yep this will never work, since Apple has abandoned OpenCL pretty much.

soulslicer commented 5 years ago

Well..it turns out it does work. All I have to do is set the GPU ID to 2. The AMD Radeon Pro 560X (default on Macbook 2018s) is roughly 3x faster in inference than the CPU is smaller resolutions.

Hello. Have you solved the problem yet? I also have this problem.

soulslicer commented 5 years ago

yup it works.
