error when call tune_tir for Android OpenCL by RPC

[huanyingjun]

Dear
I use rpc to tune my Tir Function On Android device for OpenCL.
My code is as below:

rpc_host = "127.0.0.1"
rpc_port = 9190
rpc_key = "android"

my_rpc_config = ms.runner.RPCConfig(
            tracker_host=rpc_host,
            tracker_port=rpc_port,
            tracker_key=rpc_key,
            session_timeout_sec=180,
        )
my_workers = my_rpc_config.count_num_servers(allow_missing=False)

def get_runner():
    runner_config = {
        "evaluator_config": ms.runner.EvaluatorConfig(
            number=3,
            repeat=1,
            min_repeat_ms=100,
            enable_cpu_cache_flush=False,
        ),
        "alloc_repeat": 5,
    }
    runner = ms.runner.RPCRunner(
        rpc_config=my_rpc_config, max_workers=my_workers, **runner_config
    )

    return runner

my_target = tvm.target.Target("opencl", host="llvm -mtriple=aarch64-linux-android")
database = ms.tune_tir(
    mod=MyModule,
    target=my_target,
    max_trials_global=64,
    num_trials_per_iter=64,
    work_dir="./",
    runner=get_runner(),
)

got below error:
