my target is apple m1
follow official guide, I successfully tuning my network with autotvm, however before tuning, the network cost about 160ms, after tuning it only turns a little fast, 130ms.
so I want to test if autoschedule could speed up my network. However , even run the modfied official script [https://tvm.apache.org/docs/how_to/tune_with_autoscheduler/tune_network_arm.html#sphx-glr-how-to-tune-with-autoscheduler-tune-network-arm-py] , I just change the target in the script like I do in the autotvm script, 
the script still could not take effect.
when I use rk3399 to test, it passed successfully.
so it is obviously that the problem is related to macos .
Does anyone know how to run the script in macos.
