Failed to legalize torch.operator "onnx.Expand"

[vitreo12]

What happened?

Hello!

I have been trying to iree-compile a converted onnx model, but I hit this error:

error: failed to legalize operation 'torch.operator' that was explicitly marked illegal
    %1806 = torch.operator "onnx.Expand"(%1804, %1805) : (!torch.vtensor<[],f32>, !torch.vtensor<[?],si64>) -> !torch.vtensor<[],f32> 

Looking at https://github.com/nod-ai/SHARK-Turbine/issues/215, it looks like Expand should be supported, since it's marked as completed. Is this the case? I tried with both the latest stable release and the most recent release candidate.
