In this GAN example, 25 images were generated, I wanted to generate 1 image, and I changed the code

‘numValidationImages = 25’ to ‘numValidationImages = 1’

This is the image I generated after training. What went wrong

在 MATLAB Online 中打开

The imtile command should be removed when you only have one image:

Go down to the Generate New Images section and change numObservations

numObservations = 1;
ZNew = randn(numLatentInputs,numObservations,"single");
ZNew = dlarray(ZNew,"CB");
if canUseGPU
    ZNew = gpuArray(ZNew);
end
XGeneratedNew = predict(netG,ZNew);
% I = imtile(extractdata(XGeneratedNew));       % Use this if numObservations is > 1
I = extractdata(XGeneratedNew);                 % Use this if numObservations == 1
I = rescale(I);
figure
image(I)
axis off
