Hi Rahul,
ArmNN doesn't support zero dimension tensors implicitly. Often this can be resolved by converting the tensor to a 1D tensor with 1 element. We have done this conversion automatically within the TfLite parser and this has worked for a particular use case we ran into. A similar solution might work for your use case too. This could be done within the ToTensorInfo() function in OnnxParser.cpp. If this resolves the issue for you I'd recommend issuing a pull request so that we can integrate it into master.
Hope that helps, ~Derek

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 - (gdb) r Starting program: /home/root/Rahul/armnn_onnx/3DDFA_ArmNN_onnx/3ddfa_armnn_onnx [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/libthread_db.so.1".

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