Mac m1 succeed tune with autotvm failed to tune with autoschedule

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 [Auto-scheduling a Neural Network for ARM CPU — tvm 0.9.dev182+ge718f5a8a documentation] , I just change the target in the script like I do in the autotvm script, image 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.
