Fine-tuning MV2 using a GPU is not hard – especially if using the tensorflow Object Detection API in a docker container. It turns out that deploying a quantize-aware model to a Coral Edge TPU is also not hard. Doing the same thing for MyriadX devices is somewhat harder. There doesn’t appear to be a good…
