I am getting error while training CNN network

imds = imageDatastore('FCD','IncludeSubfolders',true,'LabelSource','foldernames');

imds.ReadFcn = @readtrain;

[imdsTrain,imdsTest] = splitEachLabel(imds,0.7,'randomized');

layers=[imageInputLayer([224 224 3])

convolution2dLayer(3,8,'Padding','same')

batchNormalizationLayer

maxPooling2dLayer(2,'Stride',2)

convolution2dLayer(3,16,'Padding','same')

reluLayer

maxPooling2dLayer(2,'Stride',2)

convolution2dLayer(3,32,'Padding','same')

classificationLayer];

options = trainingOptions('sgdm', ...

'Plots', 'training-progress', ...

'LearnRateSchedule', 'piecewise', ...

'LearnRateDropFactor', 0.2, ...

'LearnRateDropPeriod', 5, ...

'MiniBatchSize', 300);

options.MaxEpochs = 30;

options.InitialLearnRate=0.001;

convert=trainNetwork(imdsTrain,layers,options);

in read train I have used the resizing of the images but i am getting an error

Error using trainNetwork (line 184)

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

Error in NewCnn (line 34)

convert=trainNetwork(imdsTrain,layers,options);

can anyone please help me with it how to run this program without any error.thank you in advance
