Python binary wheels now have to be built for aarch64 for them to work inside the container, unless they are built using the corresponding build system while installing. It is not common for python binary libs to publish arm64 binary wheels, as most often they target amd64.

Isn't that just expected for modern macOS devices? They have been on arm64 for 6 years now.

This however is for Linux containers on macOS, and for those the deployment target are not usually/necessarily arm.

(Plus, you could always even have amd64 linux containers on macOS AS, with good performance, via Rosetta2).
