   I did a few tests with the script you provided and I'm fairly certain this has nothing to do with `apply_history_best`. I think this is instead an issue of whether tophub schedules are applied or not. It seems like calling task extraction registers tophub schedules that can override the manually tuned schedules, which in your case seems to be causing the worse performance. A good way to test this would be using a workload that isnt in tophub, maybe just by changing the input shapes to resnet.
