ArmNN | ONXX model load issue - Armnn-dev

22 Aug 2019

      Hi,
We are using ArmNN to cross-compile a standalone C++ application on Linux
that loads a standard onnx model. During the model loading, we see a crash
with the below error output -
terminate called after throwing an instance of
'armnn::InvalidArgumentException'
  what():  Tensor numDimensions must be greater than 0
Initially we were on armnn master, and later we switched to tag v19.05, but
the error was same for both.
Below is the code snippet to load the model -
        armnnOnnxParser::IOnnxParserPtr parser =
armnnOnnxParser::IOnnxParser::Create();
        std::cout << "\nmodel load start";
        armnn::INetworkPtr network =
parser->CreateNetworkFromBinaryFile("onnx_3DDFA.onnx");
        std::cout << "\nmodel load end";
It crashes after printing "model load start" with the error message printed
above.
A gdb backtrace is also provided below -

Can someone point out if we are missing something out or doing something
wrong? Any help or input is highly appreciated.
