I'm new to Neo4j and trying to connect python and neo4j database.
I've created Neo4j database with name = "test", password = "test" and then run it.
Then I started Jupyther notebook and run
!pip3 install neo4j
After succesful installation I run
from neo4j import GraphDatabase
graphdb = GraphDatabase.driver(uri = 'bolt://localhost:7687', auth = ('test', 'test'))
In learinig video and tutorials this step was succesful but I have error ValueError("do_handshake_on_connect should not be specified for non-blocking sockets")
What I do wrong and how can I fix the problem?
Thank you in advance.
