Ran in:
I am trying to implement Deep Learning model with my dataset and doing tranfer learning. When I run the given code below:
NumberOfClasses = 2;
nn = inceptionv3;
imageSize = nn.Layers(1, 1).InputSize;
lgraph = layerGraph(nn);
lgraph = replaceLayer(lgraph, 'predictions', fullyConnectedLayer(NumberOfClasses, 'Name', 'FC2'));
lgraph = replaceLayer(lgraph, 'ClassificationLayer_predictions', classificationLayer('Name', 'Output'));
layers = lgraph.Layers;
connections = lgraph.Connections;
obj.NN = createLgraphUsingConnections(layers, connections);
'createLgraphUsingConnections' is used in Train Deep Learning Network to Classify New Images.
I get error: 'createLgraphUsingConnections' is used in Train Deep Learning Network to Classify New Images.
How I can fix this issue?
Note: I am using MATLAB R2022a version.

% lgraph = createLgraphUsingConnections(layers,connections) creates a layer
% graph with the layers in the layer array |layers| connected by the
% connections in |connections|.
function lgraph = createLgraphUsingConnections(layers,connections)
lgraph = layerGraph();
for i = 1:numel(layers)
lgraph = addLayers(lgraph,layers(i));
end
for c = 1:size(connections,1)
lgraph = connectLayers(lgraph,connections.Source{c},connections.Destination{c});
end
end
I found this code @ Link.

This is the example that the error message is referring to: https://www.mathworks.com/help/deeplearning/ug/train-deep-learning-network-to-classify-new-images.html
createLgraphUsingConnections is a helper function used by the example. You can access this function by opening the example files in MATLAB:
openExample('nnet/TransferLearningUsingGoogLeNetExample')
Make sure the function is on the MATLAB path before calling it.
