how can i fix this error Error using gpuArray/arrayfun 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)'.

   YTest = classify(cifar10Net, testDigitData);

I am using MATLAB 2017a

Use less memory?

Answer 1

Try reducing the number of digits you are trying to classify at once, to reduce the amount of memory needed to process them. See the 'MiniBatchSize' setting.

[Huawei Tian]

when I set MiniBatchSize as 20, only 20 image are feed to classify! How can I feed next 20 images?

[Joss Knight]

If you passed all your data to classify, all of it will be classified. So you'll have to post the code you are using so we can see what you're actually doing.
