neural network toolbox classify(net, x) function not working

matlab classify(net,x) generating undefined

overtime i run classify(net,x) on a trained neural network i get this output

my neural network is convolutional neural network that is trying to classify cancer images. Im using nfold cross validation andntrying to measure accuracy of each fold. For my second fold works fine but my first fold is generating this weird output. Im training my network 5 time for 5-fold cross validation and getting accuracy average over those 5

here is my code :

convnet11Fold1  = trainNetwork(Train1,layers,options)
save convnet11Fold1

YPred1 = predict(convnet11Fold1,nfoldTest1)

YTest1 = classify(convnet11Fold1,nfoldTest1)
TTest1 = nfoldTest1.Labels

accuracy1 = sum(YTest1 == TTest1)/numel(TTest1)

accuracyTotal(end+1)= accuracy1
totalT(end+1)= numel(TTest1)
totalY(end+1)= numel(YTest1)
convnet11Fold2  = trainNetwork(Train2,layers,options)
save convnet11Fold2

YTest2 = classify(convnet11Fold2,nfoldTest2)
TTest2 = nfoldTest2.Labels

accuracy2 = sum(YTest2 == TTest2)/numel(TTest2)

accuracyTotal(end+1)= accuracy2
totalT(end+1)= numel(TTest2)
totalY(end+1)= numel(YTest2)
