arm64 on Github Actions

[richardburleigh]

Really nice work on this repo!

I've been trying to get Github Actions working on my fork, but no matter what cmake arguments I add, it always generates an x86 wheel.

How did you manage to generate arm builds?

I built the wheels on my developer device. Even it is possible to build arm64 binaries on intel architecture macs, it is difficult. What could possibly work is to change the CC variable to CC='clang -arch=arm64' before building, but I have not tried it yet.

You can currently try to build OpenVINO's 2022.3 branch with -DCMAKE_OSX_ARCHITECTURES=arm64 . and it should perform all magic

@ilya-lavrenov Thanks, I will give it a try. Is building an universal binary possible as well?

[ilya-lavrenov]

No, since ARM plug-in consists of NEON which can not be compiled for x86

I compiled Openvino Arm successfully on Raspberry PI 4 and Orange PI and after a little sweating it ran OK, but the performance is terrible on Raspberry PI 4 (4G) vs i3/4G. On the new Orange PI 5 (8G) it is better but only 1/3 the performance of NUC i3 (Ubuntu) which is nearly the same price. ARM needs a lot of boosts to match Intel CPU. In the meanwhile, has anyone tried the NVIDIA plugin for Openvino? I tried with Jetson Nano without any luck keep asking for CUDART etc.

Thanks for the pip repo anyway.
