srand99 opened a new issue #2753: Problem while use padding in pooling layer
URL: https://github.com/apache/incubator-mxnet/issues/2753
 
 
   I find some differences between mxnet and cudnn while use padding in pooling layer.
   
   If I have an input map like this:
   -1 -2 -3 .........
   -3 -4 -5 ........
   -2 -3 -6..........
   ..........................
   
   and use a max pooling layer with kernel=(3,3), stride=(2,2), pad=(1,1)
   in mxnet ,using CPU, the first value of output map is 0.
   in caffe or cudnn, the first value of output map is -1, because the padding "0" are ignored in pooling.
   if I use cudnn in mxnet, the result will be -1 too.
