Hi,
I get this error :
------
Error in minibatchqueue (line 290)
numVariables = numel(getPreviewFromDatastore(originalDatastore));
Error in ourmodel (line 32)
mbqLDTrain = minibatchqueue(imdsLDTrain,MiniBatchSize=miniBatchSize, ...
------
Part of the code:
miniBatchSize = 1;
mbqLDTrain = minibatchqueue(imdsLDTrain,MiniBatchSize=miniBatchSize, ...
MiniBatchFormat="SSCB",DispatchInBackground=canUseGPU);
mbqHDTrain = minibatchqueue(imdsHDTrain,MiniBatchSize=miniBatchSize, ...
MiniBatchFormat="SSCB",DispatchInBackground=canUseGPU);
My matlab is R2021a version with Deep Learning Toolbox.
How do i fix this error ?
Thank You

Great! So there's your answer. When you modified this example you presumably forgot to copy over the accompanying file augmentDataForLD2HDCT.m.

Make sure the accompanying file augmentDataForLD2HDCT.m that comes with this example is on the path when you run your code.
