helperImportMatConvNet error-- Supports only AlexNet

As I could observe, this SeriesNetwork object from the Neural Network Toolbox imports MatConvNet network into a SeriesNetwork object and the function supports only the AlexNet model from MatConvNet. Do we have this function restructured to support the other models in the Matconvnet toolbox?

Yes. You can for example load VGG16 with following code:

>> cnnURL = ‘http://www.vlfeat.org/matconvnet/models/beta16/imagenet-vgg-f.mat’;
>> cnnMatFile = 'imagenet-vgg-f.mat';
>> websave(cnnMatFile, cnnURL);
>> convnet = helperImportMatConvNet(cnnMatFile);

Thanks a lot for that info. Do we have this Series network object "helperImportMatConvNet" written for GoogleNet and Microsoft ResNet?

Hi, Against what you mentioned, it is not supporting the VGG 16 pre-trained model. it gives an error:

convnet = helperImportMatConvNet(cnnMatFile);

Error using helperImportMatConvNet>getPadding (line 233)
Only symmetric padding is supported

Error in helperImportMatConvNet>createPoolLayer (line 122)
padding  = getPadding(l);

Error in helperImportMatConvNet (line 56)
            layers{end+1} = createPoolLayer(l);

Kindly help with this.

I have the same error when I want to use googleNet or resNet

[Debanjan Lahiri]

I have the same error for % Specify folder for storing CNN model

cnnMatFile = 'C:\Users\Anand\Desktop\MATCONVNET\imagenet-vgg-f.mat';

% Load MatConvNet network into a SeriesNetwork

Net = helperImportMatConvNet(cnnMatFile);

as

"Error using helperImportMatConvNet>getPadding (line 233) Only symmetric padding is supported

Error in helperImportMatConvNet>createPoolLayer (line 122) padding = getPadding(l);

Error in helperImportMatConvNet (line 56) layers{end+1} = createPoolLayer(l);

Error in load_saved_network (line 22) Net = helperImportMatConvNet(cnnMatFile);"

Pls. help in this issue

U can tweak this function of getPadding() to work for other models as well.
