deepdream error at cuda

hi i want to see the deepdream image of googlenetwork pool1-norm1 it works for next layers i receive error

anyone knows what this error means ?

Error using nnet.internal.cnngpu.convolveForward2D

Unexpected error calling cuDNN: CUDNN_STATUS_BAD_PARAM.

 net_ser = SeriesNetwork(netGoogleTrained.Layers);
  layern='pool1-norm1';%5 ok
  layern='inception_3a-3x3'%16  fail
 ch=[1 2];
 I = deepDreamImage(net_ser,layern,ch);
 
 figure
for i = 1:2
    subplot(2,1,i)
    imshow(I(:,:,:,i))
end

Hi Michael, thanks for your question.

deepDreamImage does not currently support DAG networks, such as GoogLeNet, and there is no way to convert a DAGNetwork into a SeriesNetwork because the latter can only be used for networks with all the layers arranged one after the other (such as AlexNet).

For other visualization techniques I suggest:

Having said this, deepDreamImage is expected to work with DAG networks in future releases.
