Applying python packages graph-tools / network x on Neo4j database

Question

I'm embarking on a self exploratory project regarding Neo4j database on the Panama Papers by ICIJ.

Aim: I would like to run python packages that does network analysis such as graph-tool, networkx on the database that is found on Neo4j.

Hence these are the steps that I took:

1. Load Neo4j-driver, which I did load
2. Connect to the Neo-4j sandbox through pycharm

This is the code:

#

from neo4j.v1 import GraphDatabase, basic_auth

driver = GraphDatabase.driver(
    "bolt://34.239.248.240:33621",
    auth=basic_auth("neo4j", "fares-documentation-reproductions"))
session = driver.session()

# What are the Entities in Panama Papers?
cypher_query = '''
MATCH (e:Entity)
RETURN e.name AS name LIMIT $limit
'''

results = session.run(cypher_query,
  parameters={"limit": 10})

for record in results:
  print(record['name'])

#

This was the error message shown:

neo4j.exceptions.ServiceUnavailable: Cannot acquire connection to Address(host='34.239.248.240', port=33621)

I've obtained the bolt/port/host from the sandbox website: https://neo4j.com/sandbox-v2/

Also, I tried to check if the neo4j-driver has been installed correctly, and I ran the testdriver code:

#

from neo4j.v1 import GraphDatabase

uri = "bolt://localhost:7474"
driver = GraphDatabase.driver(uri, auth=("neo4j", "user"))

def print_friends_of(name):
    with driver.session() as session:
        with session.begin_transaction() as tx:
            for record in tx.run("MATCH (a:Person)-[:KNOWS]->(f) "
                                 "WHERE a.name = {name} "
                                 "RETURN f.name", name=name):
                print(record["f.name"])

print_friends_of("Alice")

#

In which this error code was shown:

neo4j.exceptions.SecurityError: Failed to establish secure connection to '[SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:749)'

Could you advise?

Answer 1

I managed to solve this problem by downloading the graph db database directly into my local server. The bolt port is 7474.
