jackwish commented on issue #3859: [TOPI][AutoTVM] NHWC conv2d templates for ARM URL: https://github.com/apache/incubator-tvm/pull/3859#issuecomment-557416474 Hi @tmoreau89 , thanks for your comments! > Do you mind checking tuned performance for e2e resnet18 and/or mobilenet? I'd like to provide e2e performance too, though it seems pretty hard before we have a dedicated depthwise NHWC schedule. I will tune some workloads from MobileNet. > One thing to keep track of is the schedule space. The tuning space is a bit larger than NCHW, but still manageable. When evaluating the performance, I have a trail of 1000 and early stop of 500 for both NCHW and NHWC. The best result is obtained at about 500th iteration even with a sufficient large workload (image size 128 with input/output channel 128). > I'd recommend adding more comments in the schedule code. For sure I agree with this. Most of the TVM schedule primitives are straightforward (to people who have experience), while the recording are basically for locality in general regarding different workloads.
