How to use Mac M1 GPU

[runski]

I read that onnx runtime v1.19.4 supports acceleration for Apple Silicon. I assume this means GPU support is now available for the M1 chip. I can't find any examples of how to specify an M1 gpu in onnx runtime.

If I specify print(ort.get_device()), it will show me a CPU device.

If I try to install onnxruntime-gpu, it can't find a version. I think this is the wrong approach, as onnxruntme-gpu refers to CUDA only.
