I am creating a neural network in MATLAB,but i got this error
Error using nntraining.setup>setupPerWorker (line 96)
Targets T{1,1} is not numeric or logical.
outputFolder= fullfile(tempdir, '');
rootFolder = fullfile(outputFolder, '');
categories = {'2', '1', '0'};
imds = imageDatastore(fullfile(rootFolder, categories), 'LabelSource', 'foldernames');
numImageCategories = size(categories(imds.Labels),1); % get category labels
[trainingDS,validationDS] = splitEachLabel(imds,0.7,'randomize'); % generate training and validation set
LabelCnt = countEachLabel(imds); % load lable information
p=[];
t1=[];
[l,m]=size(trainingDS.Files);
for q=1:l
im1=readimage(trainingDS,q);
im=double( im1);
[r,c]=size(im)
p11=[];
for i=1:r
for j=1:c
p11=[p11;im(i,j,1)];
end
end
p=[p p11];
t1=[t1 trainingDS.Labels(q)];
t = categories(t);
end
