无法使用gremlinpython进行查询

我正在使用

gremlinpython

访问Janusgraph中的数据，但是它抛出了一个异常，而数据可以从gremlinshell访问

下面是我正在远程运行的Python代码：

from gremlin_python import statics
from gremlin_python.structure.graph import Graph
from gremlin_python.process.graph_traversal import __
from gremlin_python.process.strategies import *
from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection

graph = Graph()
g = graph.traversal().withRemote(DriverRemoteConnection('ws://<IP>:8182/gremlin','g', 
username="janusgraph"))
print g.V().has('name', 'saturn').next()
