Just tested on latest VS updates and still seems totally broken. I've seen a blog post about this working, is this supported?

@JakeRadMSFT @LittleLittleCloud -- is it possible that modelbuilder is deploying the wrong binaries in this case?

I do think a standalone app should be able to work here.

Unfortunately text classification uses torchsharp trainer behind and Torchsharp doesn't support arm device yet. So it's currently expected that the text classification training doesn't work on arm device.

Looks like there's ongoing PR to support arm device, we can probably support arm64 device after that PR get merged
