kice commented on issue #4523: Optimization for subpixel layer on Tensor core URL: https://github.com/apache/incubator-tvm/issues/4523#issuecomment-575894939 ConvertLayout only support NHWC(tf) -> NCHW(tvm), but I used mxnet to make the layout conversion manually, and it turned out even slower. I think there is something to do with NVIDIA driver, I can still see layout conversion in nvprof.
