Subject [GitHub] [incubator-tvm] Observer007 opened a new issue #5610: time cost gap between autotvm and running.
Date Mon, 18 May 2020 02:55:51 GMT

Observer007 opened a new issue #5610:

   I tune a 1x1 conv with shape 28*128*56*56 and got a time cost gap between autotvm tuning
log and actual running. The gap is about 0.01-0.05 ms and total execute time is 0.7-0.8 ms.
   I used autoTVM tuning and got up to 3800 gflops, but during running with best parameters,
I just got 3600 gflops.
   The target and other parameters are same during tuning and running. My machine is intel
   I used time_evaluation api and read its source code. I find that the call of RPC and other
target are different. AutoTVM uses rpc and my running uses llvm. So is this the case?
