MATLAB: Problem with cifar10 download

cnn cifar10 downloads

I'm trying to download cifar10 image set from web page with commands:
%%Download the CIFAR-10 dataset
if ~exist('cifar-10-batches-mat','dir')
    cifar10Dataset = 'cifar-10-matlab';
    disp('Downloading 174MB CIFAR-10 dataset...');   
    websave([cifar10Dataset,'.tar.gz'],...
        ['https://www.cs.toronto.edu/~kriz/',cifar10Dataset,'.tar.gz']);
    gunzip([cifar10Dataset,'.tar.gz'])
    delete([cifar10Dataset,'.tar.gz'])
    untar([cifar10Dataset,'.tar'])
    delete([cifar10Dataset,'.tar'])
end
but I get this info
Downloading 174MB CIFAR-10 dataset...
Error using websave (line 103)
Unable to open output file: 'cifar-10-matlab.tar.gz' for writing. Common reasons include that the file exists and
does not have write permission or the folder does not have write permissions.
Error in DownloadCIFAR10 (line 13)
    websave([cifar10Dataset,'.tar.gz'],...
I can't find file cifar-10-matlab.tar.gz on my computer.
Previously I downloaded the image set, but I deleted everything – including subfolders, testdata etc.
How can I succesfully download cifar10 image set?

Best Answer

cd to a directory that you have write access to. You are probably currently in a directory where MATLAB was installed.
