hi Joshua, this is super cool! We’ve discussed this among ourselves but never had the time to do it. Last time I used raspberrypie was > 8 years ago … and there was only a C compiler.
But maybe @Mathieu  would be interested in trying ? (He may take a week to reply though)
Some considerations:


Some of the optimized inference engines do take advantage of things link AVX-2, but they could be disabled.


I’m not sure what kind of C++ compiler is available for the armv7.


Yggdrasil does depend on a few other libraries, not sure if they compile.


I’m assuming you are trying to have only the inference engine (to make model predictions, not to train) run in raspberry pi, right ? (although in principle training should work as well).
Let me suggest the following: add an “issue” in the Yggdrasil github, we’ll mark it as an enhancement. And maybe add more details of what are the errors there. No promises about timeline we would work on it, but having these models running on edge devices (including raspberry pi) is high on our wish-list.
