Gremlin/Python: run query as string - gremlin

Question

I have the following code, and run as expected. But I need to use the "g" traversal object to manipulate the graph.
from gremlin_python.process.anonymous_traversal import traversal
from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection
g = traversal().withRemote(DriverRemoteConnection('ws://localhost:8182/gremlin','g'))
g.V().drop().iterate()
g.addV('my-label').property('k', 'v').next()
print(g.V().toList())
Instead of the "g" object, I want to run string query to modify the graph, and the following doesn't work.
from gremlin_python.driver import client
from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection
ws_conn = DriverRemoteConnection('ws://localhost:8182/gremlin','g')
gremlin_conn = client.Client(ws_conn, "g")
query = "g.V().groupCount().by(label).unfold().project('label','count').by(keys).by(values)"
response = gremlin_conn.submit(query)
print(response)
Gives the following error:

This works.
from gremlin_python.driver import client
from tornado import httpclient
ws_url = 'ws://localhost:8182/gremlin'
ws_conn = httpclient.HTTPRequest(ws_url)
gremlin_conn = client.Client(ws_conn, "g")
query = "g.V().groupCount().by(label).unfold().project('label','count').by(keys).by(values)"
response = gremlin_conn.submit(query)
print(response)
