Impossible to import .onnx with importONNXLayers

I am trying to import different onnx models from official repo. importONNXLayers always ends with error:
- ArcFace throws: Error using importONNXLayers (line 39) Size vector must have at least two elements.
- SqueezeNet throws: Error using importONNXLayers (line 39) Node 'squeezenet0_flatten0_reshape0': The Reshape operator is supported only when it performs a flattening operation.
- Emotion FerPlus throws: Error using importONNXLayers (line 39) Node 'Times622_reshape1': The Reshape operator is supported only when it performs a flattening operation.
I followed official documentation for using importONNXLayers function:
layers = importONNXLayers('squeezenet1.1.onnx','OutputLayerType','classification');
What is wrong here?

Hi, I have encountered this problem with different error after downloading the support package.
modelfile = 'cifarResNet.onnx';
classes = ["airplane" "automobile" "bird" "cat" "dee" "dog" "frog" "horse" "ship" "truck"];
net = importONNXNetwork(modelfile,'OutputLayerType','classification','Classes',classes)
Error using onnxmex
Opening file 'cifarResNet.onnx' failed.
Error in nnet.internal.cnn.onnx.ModelProto (line 31)
ModelPtr = onnxmex(int32(FuncName.EdeserializeFromFile), filename);
Error in nnet.internal.cnn.onnx.importONNXNetwork (line 8)
m = nnet.internal.cnn.onnx.ModelProto(Filename);
Error in importONNXNetwork (line 53)
Network = nnet.internal.cnn.onnx.importONNXNetwork(ModelFile, varargin{:});
I don't understand as well. Are you able to run the code above?

Those ONNX models are somewhat unusual in their use of the Reshape operator. We are actively working on supporting more ONNX operators, and we specifically aim to be able to import models in the ONNX model zoo.

I also encountered the misplacement of the imported onnx model. I exported the pre-trained alexnet in pytorch, but the following error occurred when importing onnx in matlab. How can I solve this problem? Thank you

It' same error, thank your advice! but i want to use other model networks in pytorch,then import to matlab to use.
importONNXNetwork/importONNXLayers does not seem to be perfect, there are many operations that are not supported, and it is hoped that the 2019a version will provide its robustness.

Ya, i guess not all the layers of deep learning are supported by MATLAB currently.
