So, I want to run this deep learning model on Matlab. It's frustrating that the code is correct, but anyway I'm receiving wierd errors.

ValidationSet = imageDatastore('C:\Users\V\Documents\MATLAB\cifar10Validation',...
   'FileExtensions', {'.png'}, 'IncludeSubfolders',true, ...
    'LabelSource','foldernames');
TrainingSet = imageDatastore('C:\Users\V\Documents\MATLAB\cifar10Train',...
   'FileExtensions', {'.png'}, 'IncludeSubfolders',true, ...
    'LabelSource','foldernames');
%-------------------Define Layers
varSize = 64;
conv1 = convolution2dLayer(5,varSize,'Padding',2,'BiasLearnRateFactor',2);
conv1.Weights = gpuArray(single(randn([5 5 3 varSize])*0.0001));
fc1 = fullyConnectedLayer(2560,'BiasLearnRateFactor',2);
fc1.Weights = gpuArray(single(randn([2560 23040])*0.1));
fc2 = fullyConnectedLayer(160,'BiasLearnRateFactor',2);
fc2.Weights = gpuArray(single(randn([160 2560])*0.1));
fc3 = fullyConnectedLayer(10,'BiasLearnRateFactor',2);
fc3.Weights = gpuArray(single(randn([10 160])*0.1));
layers = [
    imageInputLayer([varSize varSize 3]);
    conv1;
    maxPooling2dLayer(3,'Stride',2);
    reluLayer();
    convolution2dLayer(5,32,'Padding',2,'BiasLearnRateFactor',2);
    reluLayer();
    averagePooling2dLayer(3,'Stride',2);
    convolution2dLayer(5,2560,'Padding',2,'BiasLearnRateFactor',2);
    reluLayer();
    averagePooling2dLayer(3,'Stride',2);
    convolution2dLayer(5, 2560, 'Padding', 2, 'BiasLearnRateFactor', 2);
    reluLayer();
    averagePooling2dLayer(3,'Stride',2);
    fc1;
    reluLayer();
    fc2;
    reluLayer();
    fc3;
    reluLayer();
    softmaxLayer()
    classificationLayer()];
%-----------TrainingOptions
options = trainingOptions('sgdm', ...
    'InitialLearnRate', 0.001, ...
    'LearnRateSchedule', 'piecewise', ...
    'LearnRateDropFactor', 0.1, ...
    'LearnRateDropPeriod', 8, ...
    'L2Regularization', 0.004, ...
    'MaxEpochs', 10, ...
    'MiniBatchSize', 100, ...
    'Verbose', true);
%Train------------------------
inputSize = layers(1).InputSize;
pixelRange = [-32 32];
imageAugmenter = imageDataAugmenter( ...
    'RandXReflection',true, ...
    'RandXTranslation',pixelRange, ...
    'RandYTranslation',pixelRange);
augTrainingSet = augmentedImageDatastore(inputSize(1:2),TrainingSet, ...
    'DataAugmentation',imageAugmenter);
%--------------
augValidationSet = augmentedImageDatastore(inputSize(1:2),ValidationSet);
[net, info] = trainNetwork(augTrainingSet, layers, options);
%Testing Part---------------------------------
[YPred,scores] = classify(net,augValidationSet);
idx = randperm(numel(ValidationSet.Files),64);
figure
for i = 1:64
    subplot(8,8,i)
    I = readimage(imdsValidation,idx(i));
    imshow(I)
    label = YPred(idx(i));
    title(string(label));
end
YValidation = imdsValidation.Labels;
accuracy = mean(YPred == YValidation);

It might be needed to mention that the laptop I'm running has a Nvidia 1050ti GPU. I would appreciate any help like necessary updates,

This is the current errror.

Error using trainNetwork (line 150)

Unexpected error calling cuDNN: CUDNN_STATUS_EXECUTION_FAILED.

****Update: After installing CUDA 10 and updating my NVIDIA driver, I still receive the same error.

Thanks!

Nearly always this error is a kernel timeout. Use Windows regedit and follow the instructions on this page to disable TDR by setting TdrLevel to 0.

Try this and get back to me.

I'm sorry, but I can't see which layer is causing the error in these lines.

I have 3.3 GB of memory available out of my 4 GB for graphic card.

 'Error using  + 
     Out of memory on device. To view more detail about available memory on the GPU, use 'gpuDevice()'. If the problem persists, reset the GPU by calling 'gpuDevice(1)'.

I suggest putting a breakpoint at nnet.internal.cnn.SeriesNetwork/updateLearnableParameters (line 431) and examine the size() of this.Layers{el}.LearnableParameters(param).Value and deltas{currentDelta} . I am wondering if you might accidentally be adding a row vector to a column vector, which would try to generate a rectangular matrix of result.

So, you have nearly enough memory but not quite, because in order to update the model parameters we need to take a temporary copy of each on this line of code.

You really are close to the wire with this model. I'm afraid I haven't the patience to do it for you, but if you run analyzeNetwork on your input layer array, and add up all the sizes of all the activations and model parameters, you'll probably find your model needs about 1 GB of space. The way training works, you need some significant multiple of that, around 3x, because you need to retain activations in memory and at least one copy of the weights.

Perhaps there's a deep learning expert here who can comment on whether your model needs to be as big as it is. Certainly, your sudden jump from 32 to 2560 channels in layer 8 seems unusual, and is probably giving you a lot of unused filters.
