Hi!

I'm working on a Jetson Xavier NX (arm64) device and I suddenly cannot use numpy installed from pip. Installing numpy 1.19.5 works but importing it gives illegal instruction error. This problem is not present if I instead install python 1.18. I have reproduced this bug on a clean system.

Reproducing code example:

This works:
pip install -U numpy

This does not:
import numpy

Illegal instruction (core dumped)
