is this software problem or hardware processor incompetibility?

any update on this?

Hi Kim,

Intel(R) Pentium(R) CPU N4200 should run fine with fp32 on CPU and also if you get OpenCL on the GPU it will also run with fp16 and -d GPU.

I would try again to run the model optimizer on a different desktop and then if successful copy the IR (bin and xml) and just run inference on the low power N4200 device.

Cheers,

Nikos
