jackwish commented on issue #3859: [WIP] [AutoTVM][TOPI] NHWC conv2d templates for ARM URL: https://github.com/apache/incubator-tvm/pull/3859#issuecomment-550989430 > Thanks @jackwish for the update. Makes sense. So, are we planning to close this PR? I agree to close this - data layout doesn't impact spatial pack convolution very much. And people interesting in this can still try @cowanmeg 's [branch](https://github.com/cowanmeg/tvm/tree/quantized_end2end) or [mine](https://github.com/jackwish/tvm/tree/topi/conv-nhwc). > I am starting to look into Conv2D schedules for ARM. I can make a alter-layout change for NHWC network to use NCHW spatial schedule. I will do it in a manner that there are as few layout transforms as possible in the whole network (hopefully just 2) to amortize the cost of layout transforms. That sounds good! We have already considered this solution internally before. Thanks everyone, this is now closing as we are not going to putting extra effort to improve the performance of Spatial Pack convolution schedule for NHWC.
