Pyarmnn and Arm NN for 64 bit raspberry pi os

Hi! Raspberry Pi OS 64-bit is still in beta, but you can try to use this guide to cross-compile ArmNN for it:

https://developer.arm.com/solutions/machine-learning-on-arm/developer-material/how-to-guides/cross-compiling-arm-nn-for-the-raspberry-pi-and-tensorflow

This guide involves building a few dependencies (boost, protobuf, Arm Compute Library), so at each stage it's necessary to pay attention to which compiler is used and which compiler flags are specified (for example, armv7a should be changed to aarch64).
