Dear MathWorks Deep Learning Toolbox Team:
Hi, I tried to use exportONNXNetwork, I ran this part of code, but i saw this error, could you help me pls?!
Usage example:
%% Export to ONNX model format
net = squeezenet;
filename = 'squeezenet.onnx';
exportONNXNetwork(net,filename);
-------------------------------------
this error appear:
Error using nnet.internal.cnn.onnx.onnxmex
Invalid MEX-file
'C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\nnet\supportpackages\onnx\+nnet\+internal\+cnn\+onnx\onnxmex.mexw64':
A dynamic link library (DLL) initialization routine failed.
Error in nnet.internal.cnn.onnx.ModelProto/writeToFile (line 50)
ModelPtr = onnxmex(int32(FuncName.EnewModelProto));
Error in nnet.internal.cnn.onnx.exportONNXNetwork (line 37)
writeToFile(modelProto, Filename);
Error in exportONNXNetwork (line 40)
nnet.internal.cnn.onnx.exportONNXNetwork(Network, filename, varargin{:});

On Mac OS using Matlab 2021a I get:
>> exportONNXNetwork(trainedNetwork_1,'ONNXThumbs.onnx')
Error using nnet.internal.cnn.onnx.onnxmex
Unexpected Standard exception from MEX file.
What() is:Failed to load ONNX Shared library.
..
Error in nnet.internal.cnn.onnx.ModelProto/writeToFile (line 52)
ModelPtr = onnxmex(int32(FuncName.EnewModelProto));
Error in nnet.internal.cnn.onnx.exportONNXNetwork (line 38)
writeToFile(modelProto, Filename);
Error in exportONNXNetwork (line 38)
nnet.internal.cnn.onnx.exportONNXNetwork(Network, filename, varargin{:});

It looks like you are hitting this bug:
- Error when using functions for importing or converting ONNX or Caffe models on Windows
- https://www.mathworks.com/support/bugreports/2465087
There is a workaround listed in that bug report.

The cause of R2021a is that the bin folder created under C:\ProgramData\MATLAB\SupportPackages\R2021a\bin\win64\ is not recognized as a system path.
The following command should help.
mv C:\ProgramData\MATLAB\SupportPackages\R2021a\bin\win64\onnxpb.dll C:\ProgramData\MATLAB\SupportPackages\R2021a\toolbox\nnet\supportpackages\onnx\+nnet\+internal\+cnn\+onnx\
