We know that NCS1 has 500MB internal memory (max. graphs up to 320MB).
What about NCS2? (could it fit YoloV2 or YoloV3?)
I'm currenty working on YoloV3 on NCS2. There are loads of problems currently (for example nearest-neighbor resampling is not supported and you must change it to bilinear). But the weight file for ssd_mobilenet_v2_coco is 33MB and for YoloV3 416x416 it's 119MB. So you should be able to fit YoloV3 even into NCS1.
If you find how to make YoloV3 work on NCS2, please message here.
