Empty model blob after compilation and [NOT IMPLEMENTED] Message

[nano]

Problem Description:

When using the compile_tool to generate a model blob like described here: https://docs.openvinotoolkit.org/latest/openvino_inference_engine_tools_compile_tool_README.html I get an empty blob object and the compile tool returns "[NOT IMPLEMENTED]"

Question:

Do I have to implement something to make the CPU compilation work? Is "CPU" not a valid identificator? What's the problem here?

System:

I tried this on my windows machine using openvino 2020.03 LTS and on my ubuntu machine v18.04 LTS with the newest apt install version.

On the ubuntu machine, using -d MYRIAD option leads to it working, but using -d CPU just returns [NOT IMPLEMENTED]. However I need the model to be compiled for CPUs.

Steps to reproduce for me (fresh installation):

- Download onnx alexnet from https://github.com/onnx/models/blob/master/vision/classification/alexnet/model/bvlcalexnet-8.onnx

- use model optimizer to generate xml and bin file like this: python mo_onnx.py --input_model path_to_onnx\bvlcalexnet-8.onnx --output_dir path_to_out

- run compile_tool -m /path_to_xml/file.xml -d CPU -o /path_to_out/out.blob

Greetings,

Fyi, the compile_tool only supports Myriad, FPGA for now and myriad_compile supports only Myriad.

Documents will be updated accordingly by the developer soon.

Sincerely,
