Using matlab example for regression

Question

I am trying to learn DL with an example. However, running the following code results in an error

imds = imageDatastore(fullfile(rootFolder),'Labels',lab.labels35_16);
imds.ReadFcn = @(filename)readAndPreprocessImage(filename);    
[trainingSet, testSet] = splitEachLabel(imds, 0.3, 'randomize');
trainingFeatures = activations(convnet, trainingSet, featureLayer, ...
    'MiniBatchSize', 32, 'OutputAs', 'columns');

sAnd the error is Undefined function 'categories' for input arguments of type 'double'. I understand that categories in he original example is string based labels. But mine is int values. Not sure why it isn't working. Kindly help

From the documentation of catogories, it seems like the input needs to be a categorical. You might have to do categories(categorical()).
