AutoTVM support for metal on MacOS with Intel GPU

On running the CoreML tutorial with a metal target on MacOS 10.14.6 with Intel Iris Graphics 640, I get the following warnings:

Is there a list of supported ops for metal target somewhere and a workaround for this issue?

This warning doesn’t mean AutoTVM doesn’t support metal on MacOS. It means no well-tuned configs are available for your workload. You can refer to this tutorial to tune the workloads.
