Generating Python code for ROS interfaces Illegal instruction (core dumped)

Hi,
I got this error when building for Xavier.
Could you please help.

Thank you.

Happened to get the same error trying to get this to run for the first time today! For me the issue was my numpy version, which seems to have caused other problems on Jetsons too - see link below with the following fix:
"It is numpy 1.19.5 issue. You can fix it by installing previous minor version. pip3 install numpy==1.19.4"
