jwfromm commented on issue #4523: Optimization for subpixel layer on Tensor core URL: https://github.com/apache/incubator-tvm/issues/4523#issuecomment-565846814 You're right that our current handling of depth2space (and space2depth) isn't optimal. We should probably have a dedicated relay op and topi implementation that directly rearranges values rather than stacking reshapes and transposes. I can try to take a stab at implementing this in the next few days.
