I wrote the following python code to neo4j using py2neo
from py2neo import Graph
from py2neo import neo4j,Node,Relationship
sgraph = Graph()
alice = Node("person",name="alice")
bob = Node("person",name="bob")
alice_knows_bob = Relationship(alice,"KNOWS",bob)
sgraph.create(alice_knows_bob)
but i got the following error

can anyone please help me.This is the first time i writing python code to connect to neo4j.
If you're using Neo4j 2.2, authentication for database servers is enabled by default. You need to authenticate before performing further operations. Read documentation.
from py2neo import authenticate, Graph
# set up authentication parameters
authenticate("localhost:7474", "user", "pass")
# connect to authenticated graph database
sgraph = Graph("http://localhost:7474/db/data/")
# create alice and bob
...
From the same documentation,
Py2neo provides a command line tool to help with changing user
passwords as well as checking whether a password change is required.
For a new installation, use:
$ neoauth neo4j neo4j my-p4ssword
Password change succeeded
After a password has been set, the tool can also be used to validate
credentials
$ neoauth neo4j my-p4ssword
Password change not required

I am using a private key authentication to connect to Snowflake using python,
**This is working successfully when connecting directly using Java Client

Thank you in advance for your help.
I can not see the rest of the error message so I couldn't be sure. Are you sure enter your account name (and region and cloud if needed) as the account parameter, instead of full Snowflake URL?
https://docs.snowflake.com/en/user-guide/python-connector-example.html#connecting-to-snowflake
When connecting Jira, usually people uses JDBC connection string which includes full snowflake URL:

The httpDomainRecordId is the Id for the domain obtained from softlayer and dataspace is the string 'uk'.
Does anyone know why this would be returning an Internal Error from the server?
Likely the error is due to the response contains a big amount of data, this error is documented here, so you can try:
1.- Increase the timeout in the client.
2.- Add more filters in your request to limmit the result, currently your using datqa and type try adding host or ttl
3.- you can try using limits, but the manager does not provide that option. so you need to use API calls e.g.
import SoftLayer
client = SoftLayer.Client()
zoneId = 12345
objectMask = "id,expire,domainId,host,minimum,refresh,retry, mxPriority,ttl,type,data,responsiblePerson"
result = client['Dns_Domain'].getResourceRecords(id=zoneId, mask=objectMask, limit=200, offset=0)
print (result)

I am running Python3.4 on OSX Yosemite. My Instgram client uses the following URI and website:
URI: http://localhost:8515/oauth_callback
Website: http://localhost:8515/oauth_callback
The problem that you have here is that in your sample.py you are trying to access to access_token in the request.session dictionary and it doesn't exists. To avoid the error you can do something like:
if 'access_token' in request.session.keys():
access_token = request.session['access_token']

You are trying to access neo4j via https on the standard port for http (7474):
url_graph_conn = "https://neo4j:password#52.10.**.***:7474/db/data/"
The standard port for a https connection is 7473. Try:
url_graph_conn = "https://neo4j:password#52.10.**.***:7473/db/data/"
And make sure you can access the web interface via https:
https://52.10.**.***:7473/browser/
You can change/see the port settings in your neo4j-server.properties file.

Is seems you use urllib3 version 1.5 or older. Upgrade it to 1.6 or 1.7.
