Unable to connect py2neo v3 with neo4j 3.4.1 - python-3.x

Question

I have been trying to connect to my local neo4j server using py2neo v3 and neo4j version 3.4.1.
The commands I used are:-
from py2neo import Graph, Node, Relationship
graphURL='http://localhost:7474/db/data/'
graphUser = "neo4j"
graphPassphrase = "XXXX"
graph=Graph(graphURL, user=graphUser, password=graphPassphrase)
I receive the following errors on trying to use this code.

I have tried using the handbook https://py2neo.org/v3/database.html?highlight=relation for v3 but it was of no use for my problem. Could you please help me with this issue.

Answer 1

The driver support the BOLT and HTTP proctole, but it seems here that you want to use the HTTP one, and the driver is trying to instantiate the BOLT ...
I recommend you to use BOLT, so your code should be :
from py2neo import Graph, Node, Relationship
graphHost='localhost'
graphUser = "neo4j"
graphPassphrase = "XXXX"
graph=Graph(bolt=true, host=graphHost, user=graphUser, password=graphPassphrase)
If you really want to use the http :
graph=Graph(bolt=false, host=graphHost, user=graphUser, password=graphPassphrase)
