Hi I have this piece of deep learning code which runs on GPU. I wish not to use GPU. How can I change the code to run only on CPU or just to use it as Array.

eg:

B_forward = gpuArray(X_test(:,:,:,ThisInds));
if size(Residuals,1) > size(B_forward,1)
              NewRes = int8(zeros(size(B_forward),'gpuArray'));
end
 if Shifts(WeightLayerIndex) ~= 0
              B_forward = gpuArray(bitshift(gather(B_forward),Shifts(WeightLayerIndex)));
end

在 MATLAB Online 中打开

B_forward = (X_test(:,:,:,ThisInds));
if size(Residuals,1) > size(B_forward,1)
              NewRes = int8(zeros(size(B_forward)));
end
 if Shifts(WeightLayerIndex) ~= 0
              B_forward = (bitshift((B_forward),Shifts(WeightLayerIndex)));
end
