failed to legalize operation 'torch.aten.arange.start_step'

[alexsifivetw]

What happened?

When trying to compile the mlir file, I encountered the error below:

error: failed to legalize operation 'torch.aten.arange.start_step' that was explicitly marked illegal
    %8 = torch.aten.triu %7, %int1_10 : !torch.vtensor<[8,9],f32>, !torch.int -> !torch.vtensor<[8,9],f32>
         ^

Looks like triu is not implemented in https://github.com/llvm/torch-mlir . We also have test failures for onnx.Trilu that would use a similar lowering path (those look like the same math 🤔).

I ran into the same issue with iree-compile from pip, but it works with a build of main.

Ah, some triu tests did start passing at https://github.com/iree-org/iree/commit/440c87019240e225bafce595be5cf61ce344e0c8. Also yes, we should push a new version to pip soon...
