DickJC123 commented on issue #13362: Add NHWC layout support to Pooling (cuDNN only) URL: https://github.com/apache/incubator-mxnet/pull/13362#issuecomment-444734362 The forced transposition I referred to is done currently by the user in the python model. With this new feature, the Transpose operators could get removed in favor of a Pooling with the new layout parameter. I'm a bit sorry that NDArray's don't carry the layout information. As a result, the layout has to travel along with the data ('out-of-band') and be passed into the operators along the way. On the other hand, having multi-input operators deal with inconsistent layouts would be a headache. Anyway, that's a discussion to be debated in its own thread.
