Hello,
when trying to train an autoencoder, no matter the input data, I get the following error:
Unable to resolve the name
Autoencoder.parseInputArguments.
Error in trainAutoencoder (line 107)
paramsStruct =
Autoencoder.parseInputArguments(varargin{:});
I've tried running the example found in here, which should work just fine, but I get the aforementioned error, plus a line indicating
Error in filename (line 21)
autoenc1 = trainAutoencoder(xTrainImages,hiddenSize1,'MaxEpochs',400,'L2WeightRegularization',0.004,'SparsityRegularization',4,'SparsityProportion',0.15,'ScaleData',
false);
From what I understand, the error is inside the trainAutoencoder function, in the paramsStruct = Autoencoder.parseInputArguments(varargin{:}) line
if nargin > 1
[varargin{:}] = convertStringsToChars(varargin{:});
end
paramsStruct = Autoencoder.parseInputArguments(varargin{:});
autonet = Autoencoder.createNetwork(paramsStruct);
autoenc = Autoencoder.train(X, autonet, paramsStruct.UseGPU);
end
I've tried looking up the error online, but to no avail. If it's something obvious I just can't see what it is. I have the needed toolboxes installed, and I get this error in the 2019 and 2020 versions of MatLab.
If anyone could help me out, I would be extremely grateful

I would suggest you to make sure to have the digitTrainCellArrayData.m file in the given path 'C:\Program Files\MATLAB\R2019a\toolbox\nnet\nndemos\nndatasets\digitTrainCellArrayData.m'. Also, try doing clear all before the code execution.

Sometimes this error is because of the name of the .m file in the running folder. it occurs when one of the .m files in the folder are the same as in the path direction.
