Gremlin Python Gizmo how to query in graph db -

i've pushed data using gremlin-python. want run spcific queries on it. i'm using gizmo that.

i want achieve degree of centrality each node. how do that?

currently i've query return same :

g.v().group(). ......1> by(id). ......2> by(union(__(), oute('mentions').count()).fold()) 

how i'm achieving is:

def query(self, q):     gizmo import mapper, request     gremlinpy import gremlin      req = request('localhost', 8182)     gremlin = gremlin('g')      mapper = mapper(request=req, gremlin=gremlin)     # s = mapper.gremlin.v().ine('mentions').count().tolist()     # res = mapper.query(gremlin=s)      # print(res.get_data()[0])     print("something")      res = mapper.query(script=q)      # print(res.get_data()[0])     print("something")     print(res.data)      print(res.first(), res.data)     # exit(0)     return res.first() 

what want display data fetched inside res variable.

but each time errors :

attributeerror: 'coroutine' object has no attribute 'data' attributeerror: 'coroutine' object has no attribute 'get_data' 

or similar try.

how fetch results fetched coroutine object?

note: sample query i'm passing function query() g.v().count()

is there other better way run generic queries python in gremlin shell , fetch results?

graph db: janusgraph

backend: cassandra

indexing backend: elasticsearch

you mention gizmo relate multiple projects, think mean one:

https://github.com/emehrkay/gizmo

according documentation, project meant tinkerpop 2.x , rexster. don't believe works tinkerpop 3.x , gremlin server janusgraph based on. if need python ogm of sort tinkerpop 3.x might consider:
