I am training an LSTM network (script called lstm_classification.m) on some time series data (MATLAB R2024a). Training uses the Deep Learning toolbox which is installed correctly. When I run the script from the GUI everything works fine, but when I call the script from R, I get the following error message:
sequenceInputLayer requires Deep Learning Toolbox.
Error in lstm_classification (line 463) sequenceInputLayer(inputSize)
Error in run (line 112)
evalin(‘caller’, strcat(script, ‘;’));
Calling the script from R used to work without issues. This error message occured only recently. This is my script lstm_classification.m around line 463 (sequenceInputLayer…):
…
%% Define LSTM Network Architecture
inputSize=nofeatures;
% numHiddenUnits=100;
numHiddenUnits=hiddenunits;
% numClasses=9;
numClasses=notreatments_afterdrop;
layers=[ …
sequenceInputLayer(inputSize)
bilstmLayer(numHiddenUnits,’OutputMode’,’last’)
fullyConnectedLayer(numClasses)
softmaxLayer
classificationLayer
];
…
What is the matter here? Is the toolbox now not accesible without the MATLAB-GUI running? It used to work perfectly. Any help is greatly appreciated.
