snflake commented on issue #10804: Use depthwise convolution(group convolution) by cuDNNv7 if available URL: https://github.com/apache/incubator-mxnet/pull/10804#issuecomment-386537855 About the speed, I used TensorRT with cudnn 7 for inference and depthwise conv is very fast regardless of dilation rate. There is no need for custom depthwise conv implementation if cudnn 7 group is used.
