False Error log complains failed to read the result of trails

[JingChen23]

Well, I just copy the code from https://docs.ray.io/en/master/tune/examples/tune-sklearn.html, add some ray.init code to let the Tune tasks run on a remote Ray cluster:

ray.init(
    address="ray://xxx.xxx.xxx.xxx:10001",
    runtime_env={"pip": ["tune-sklearn==0.4.6",
                         "scikit-learn==1.0.2"]
                 },
)

However I met below log:

2023-07-10 18:37:16,273	WARNING experiment_analysis.py:917 -- Failed to read the results for 6 trials:

After some triage I found the files under /home/ray/ray_results/_Trainable_2023-07-10_03-36-56 do exist on the remote cluster's head node. But what the code from https://docs.ray.io/en/master/tune/examples/tune-sklearn.html doing is to read the remote logs from my local dev machine, which definitely will fail because the results of the 6 trails don't exist locally.

So the question is: Why the code will try to read the results on the remote host from local? Is this a bug or it is my fault?
