Dear All,,, It's my first time to use the Convolutional Neural Net training commands. I'm using this line to resize my training images

Folder = '256_ObjectCategories'; digitData = imageDatastore(Folder,'IncludeSubfolders',true,'LabelSource','foldernames'); digitData.ReadFcn = @(loc)imresize(imread(loc),[128 128],'nearest','Colormap','original');

However, I still get this error:

Unexpected image size: All images must have the same size.

Any help please ?

I also can't completely understand this line: digitData.ReadFcn = @(loc)imresize(imread(loc),[128 128],'nearest','Colormap','original'); But I found it in MathWorks documentation
