Error building pytorch in Windows ARM64

[tranlm]

I'm trying to follow the official instructions for building pytorch/libtorch on Windows ARM64, and keep running into the following error. Searches online have not yielded anything useful and I'm hoping the developers can give me some idea of what I'm missing. It appears to be trying to build an x86 version, despite my building it on my Windows ARM64 unit. Here's the output:

Hey @tranlm , thanks for the reporting issue.

It seems like you're having some trouble in third_party\cpuinfo.
Let's make sure if your submodule is correctly fetched.

---

We recently updated the pytorch - main and Building for Windows on ARM64.

Could you please try again in a clean environment (you may create a new folder)?

---

For your case:

• Updated steps for libuv should resolve following warning:

Libuv is not installed in current conda env. Set USE_DISTRIBUTED to OFF

• Please double check this step cloning-pytorch

  • You should fetch the latest pytorch@main

  • You should sync and update submodules

---

Please let us know if issue still persists.
