openvino: OpenVINO 2020.1 doesn't work on Raspberry Pi and NCS2

OpenVINO 2020.1 simply refuses to work when using the NCS2 in a Raspberry Pi. I’m seeing the error below. I have tested multiple sample applications using both C++ and Python and all give the same error.

./build/simple_classifier_cpp googlenet-v1.xml ../../data/images/nps_electric_guitar.png ../../data/ilsvrc12/synset_labels.txt
terminate called after throwing an instance of 'InferenceEngine::details::InferenceEngineException'

The axis must => 0 and <= input_rank (axis: 4294967295).

Give this a try.

Remove or move your current Openvino
Use the 2020.1.023 Openvino version with the 2019 R1 models
wget https://download.01.org/opencv/2020/openvinotoolkit/2020.1/l_openvino_toolkit_runtime_raspbian_p_2020.1.023.tgz
Install it

Then download the 2019 R1 models such as:

wget --no-check-certificate https://download.01.org/opencv/2019/open_model_zoo/R1/models_bin/face-detection-adas-0001/FP16/face-detection-adas-0001.bin
wget --no-check-certificate https://download.01.org/opencv/2019/open_model_zoo/R1/models_bin/face-detection-adas-0001/FP16/face-detection-adas-0001.xml

I have a Pi 4 with the NCS 2 and it worked properly. Good luck!

@alalek Are you sure master branch opencv? I just compiled and error persist
