Load ONNX CNTK C++ raises exception - cntk

Question

I have one file that I created in matlab. I used it very well in
python load:
import cntk as C
z = C.Function.load("Net.onnx", format=C.ModelFormat.ONNX)
in c++ I have exception Selected CPU as the process wide default device.
About to throw exception:
'Gemm: Invalid shape, input A and B are expected to be rank=2
matrices'
I used the nuget imported : CNTK.CPUOnly CNTK.Deps.MKL CNTK.Deps.OpenCV.Zip
#include <stdio.h>
#include "CNTKLibrary.h"
void main(){
std::wstring modelFile(L"Net.onnx");
//line crash
CNTK::FunctionPtr modelFunc = CNTK::Function::Load(modelFile, CNTK::DeviceDescriptor::CPUDevice(), CNTK::ModelFormat::ONNX);
}

Answer 1

finaly i made other solution i save in python to model cntk than loaded it from c++
in cntk format (where original model was exported from matlab to onnx long way)
python code
import cntk as C
z = C.Function.load("Net.onnx", format=C.ModelFormat.ONNX)
z.save(os.path.join("folder", "net" + ".dnn"))
c++ loading
#include "CNTKLibrary.h"
std::wstring modelFile(L"net.dnn");
CNTK::FunctionPtr modelFunc = CNTK::Function::Load(modelFile, CNTK::DeviceDescriptor::CPUDevice());
