Can not load the official model person-detection-retail-0013 in my own app

[Debasish]

My platform details: Mac OS Catalina, Clang compiler, Openvino v2021.1

I have written a code that is similar to the sample application. But the sample application can run fine with the model but not my own code. It throws different error for different model file variants. The error is throw at below statement in the code.

openvino_ = ie.LoadNetwork(network, device_name);

fp32

I have attached a sample app that reproduces this error at me end. 

You will need to change the root_path in the main_application.cpp to the model file directory (fp32 version of model already present inside the data folder).

Then run

cd build && cmake .. && make -j2
