why this Warning message occur: Support for GPU devices with Compute Capability 5.0 will be removed in a future MATLAB release? how can fix it?

I have a matlab code to classify x-ray dataset. I used the Googlenet model with augmentation for classiying. But each time I try to run the code a warning message occur.
the matlab code is:
clear
clc
datapath='dataset';
imds=imageDatastore(datapath,'includeSubfolders',true,'LabelSource','foldernames');
total_split=countEachLabel(imds);
num_images=length(imds.Labels);
perm=randperm(num_images,4);
figure;
for idx=1:length(perm)
subplot(2,2,idx);
imshow(imread(imds.Files{perm(idx)}));
title(sprintf('%s',imds.Labels(perm(idx))))
end
num_folds=5;
for fold_idx=1:num_folds
fprintf('processing %d among %d folds \n',fold_idx,num_folds);
test_idx=fold_idx:num_folds:num_images;
imdsTest = subset(imds,test_idx);
train_idx=setdiff(1:length(imds.Files),test_idx);
imdsTrain = subset(imds,train_idx);
net=googlenet;
lgraph=layerGraph(net);
clear net;
numClasses = numel(categories(imdsTrain.Labels));
newLearnableLayer=fullyConnectedLayer(numClasses,...
'name','new_fc',...
'weightLearnRateFactor',2,...
'BiasLearnRateFactor',2);
lgraph=replaceLayer(lgraph,'loss3-classifier',newLearnableLayer);
newsoftmaxLayer = softmaxLayer('Name','new_softmax');
lgraph = replaceLayer(lgraph,'prob',newsoftmaxLayer);
newClassLayer=classificationLayer('Name','new_classoutput');
lgraph = replaceLayer(lgraph,'output',newClassLayer);
imdsTrain.ReadFcn=@(filename)preprocess_xray(filename);
imdsTest.ReadFcn=@(filename)preprocess_xray(filename);
options=trainingOptions('adam',...
'MaxEpochs',10,'miniBatchSize',8,...
'Shuffle','every-epoch',...
'InitialLearnRate',1e-4,...
'Verbose',false,...
'Plots','training-progress');
augmenter = imageDataAugmenter( ...
'RandRotation',[-5 5],'RandXReflection',1,...
'RandYReflection',1,'RandXShear',[-0.05 0.05],'RandYShear',[-0.05 0.05]);
auimds = augmentedImageDatastore([224 224],imdsTrain,'DataAugmentation',augmenter);
netTransfer=trainNetwork(auimds,lgraph,options);
augtestimds=augmentedImageDatastore([224 224],imdsTest);
[predicted_labels(test_idx),posterior(test_idx,:)] = classify(netTransfer,augtestimds);
save(sprintf('ResNet50_%d_among_%d_folds',fold_idx,num_folds),'netTransfer','test_idx','train_idx');
clearvars -except fold_idx num_folds num_images predicted_labels posterior imds netTransfer;
end
when run code, these messages occur:
processing 1 among 5 folds

What shall I do to fix the problem?

warning("off","parallel:gpu:device:DeviceDeprecated");

You have several options:
  • you can upgrade your gpu hardware to Pascal architecture or later
  • you can wait a couple of releases until Maxwell and earlier are not supported at all, in which case the code will stop working with a different error message, solving the problem of receiving this error message
  • you could ignore the warning message and deal with the situation when eventually your code fails in a new release
  • you could turn off the warning and deal with the situation eventually when your code fails in a new release
