[feifeibear]

Hi, I try to follow the basic query example.
After I launch the python script.
python example_client.py
I met the following problem.
20-10-10:10:49:22 WARNING [decorators.py:34] [default-cluster] Clipper still initializing: query frontend end point http://localhost:1337/metrics health check failed, Retrying in 1 seconds..
