[BUG REPORT]Can not find valid schedule when tuning resnet

Troubleshooting
#1

Hi, I am using M1 mac to tune resnet50. I have installed tvm and following the tutorial. But an error occur when I try to tune resnet50 both on command and using python code. Here is my command

tvmc tune \
--target "llvm" \
--output resnet50-v2-7-autotuner_records.json \
resnet50-v2-7.onnx

However, this is the error I met.

/tvm/target/target.py:272: UserWarning: target_host parameter is going to be deprecated. Please pass in tvm.target.Target(target, host=target_host) instead.

It seems that it could not find a schedule for this operation. And this operation is x86 arch. But my pc is M1 mac. And I find the report which is stored in log

Is there any problem that I should tell which kind of mcpu should compile to?
