Request for support of ExecuTorch pip package on linux aarch64

[vikasbalaga]

🚀 The feature, motivation and pitch

Hi,

I am currently working with ExecuTorch on different platforms (x86 and aarch64).
While trying to install ExecuTorch python package on Raspberry Pi 5 (aarch64) through pip, I am facing the below issues :

ERROR: Ignored the following yanked versions: 0.1.0, 0.1.2
ERROR: Could not find a version that satisfies the requirement executorch (from versions: none)
ERROR: No matching distribution found for executorch

In the PyPI index, I have observed that it only supports x86 and MacOS aarch64 but not Raspberry Pi 5

So, is there any effort being done to support aarch64 on Raspberry Pi?

@vikasbalaga one option is to build from source and install, instructions are here https://pytorch.org/executorch/stable/using-executorch-building-from-source.html

@mergennachin @larryliu0820 @metascroy i think we have packages in pypi for arm64, but i think we also might need to do for aarch64?

@digantdesai You built ET for rasberryPI once right?

We don't have linux arm64 https://download.pytorch.org/whl/executorch/

We have linux x86_64 and mac arm64

I tried this step, by launching some setup scripts available in the examples/arm folder (although accidentally) and I could then see a python package getting installed and is working

Name: executorch
Version: 0.5.0a0+1bc0699

We actually have a CI job on linux aarch64 so technically it should work (#9207, #9251)

So perhaps the only delta is creating and publishing pip wheel targeting linux aarch64 to pypi
