CI: move arm64 build to azure #38617
xref #38617

I'm not sure why azure won't allow me to run a script. It says permission denied. The aarch64 build timed out.  should investigate how many cores that this chip has. i think we need to make this *much* faster. hasn't even compiled after 30 min

maybe look at numpy recipe for aarch64 > should investigate how many cores that this chip has. i think we need to make this _much_ faster. hasn't even compiled after 30 min

I think It's this slow due to that we need to use qemu to emulate arm64 in the container. NumPy uses Travis for arm64 build. I wonder how they are going to deal with this Travis credit issue.  > > should investigate how many cores that this chip has. i think we need to make this _much_ faster. hasn't even compiled after 30 min

so we *can* use travis.com and if its only for a couple of builds its fine. though that build also was taking > 1 hr which seems crazy. i guess we can just do this on the new travis.com close for now.
