missing xmmintrin.h on ARM devices.

[gahoo]

I'm trying to install n2 on Jetson AGX Xavier which is ARM based with pip install n2. But it seems xmmintrin.h is not avialable on arm. Are there any solutions for this? Is sse2neon one of the solution? Here's the error message.

This would be very useful functionality. I tried a few options here, but no luck: https://stackoverflow.com/questions/11228855/header-files-for-x86-simd-intrinsics

I believe this is what we need: https://github.com/oddconcepts/n2o/commit/fe6214dcc06a1b13be60733c53ac25bca3c2b4d0
