Hi, I have 800 images and labels in data set and I wanted to divide it into test, train and validation set.
I am using following code:
load gTruth % load gTruth file of training data
[imds,pxds] = pixelLabelTrainingData(gTruth);
imdsTrain=imds(81:720);
pxdsTrain=pxds(81:720);
imdsTest=imds(1:80);
pxdsTest=pxds(1:80);
imdsVal=imds(721:800);
pxdsVal=pxds(721:800);
its not working, any possible solution....?

[imds60, imds10, imds30] = splitEachLabel(imds,0.6,0.1)

While using this command, I am getting following error:
Error using matlab.io.datastore.ImageDatastore/splitEachLabel (line 211)
splitEachLabel requires non-empty Labels property.
