DickJC123 commented on issue #13749: Add NHWC layout support to Pooling (cpu, gpu cuda, gpu cuDNN) URL: https://github.com/apache/incubator-mxnet/pull/13749#issuecomment-458645654 Thanks for your detailed thoughts. I view this PR as filling in a missing piece in the MXNet support for NHWC (with Convolution and Batchnorm already supporting it). The performance benefit of having end-to-end support of NHWC (thereby avoiding transposes) was demonstrated for Volta hardware in https://mlperf.org/results/. We're offering this benefit to upstream with this PR (along with others to come). Once we complete the NHWC API support with this PR, I look forward to joining the discussion on how to make experimenting with layout easier for the user or done automatically.
