AuthError trying to connect to neo4j from python

I'm trying to run neo4j in a docker container and connect to it from a python script not running in a container, but I'm getting AuthError.
I'm following the instructions from here
Start neo4j
docker run \
--publish=7474:7474 --publish=7687:7687 \
--volume=$HOME/neo4j/data:/data \
--volume=$HOME/neo4j/logs:/logs \
neo4j:3.5
I've also done this with these added insturctions "By default Neo4j requires authentication and requires you to login with neo4j/neo4j at the first connection and set a new password. You can set the password for the Docker container directly by specifying --env NEO4J_AUTH=neo4j/ in your run directive."
Start neo4j
docker run \
--publish=7474:7474 --publish=7687:7687 \
--volume=$HOME/neo4j/data:/data \
--volume=$HOME/neo4j/logs:/logs \
--env NEO4J_AUTH=neo4j/neo \
neo4j:3.5
After doing either of these, I am able to connect via the web interface at http://localhost:7474/
Now I want to connect with a python script as described here which has me run this code (note I've changed the password to match the NEO4J_AUTH setting from the docker command).
from neo4j import GraphDatabase
class HelloWorldExample:
def __init__(self, uri, user, password):
self.driver = GraphDatabase.driver(uri, auth=(user, password))
def close(self):
self.driver.close()
def print_greeting(self, message):
with self.driver.session() as session:
greeting = session.write_transaction(self._create_and_return_greeting, message)
print(greeting)
#staticmethod
def _create_and_return_greeting(tx, message):
result = tx.run("CREATE (a:Greeting) "
"SET a.message = $message "
"RETURN a.message + ', from node ' + id(a)", message=message)
return result.single()[0]
if __name__ == "__main__":
greeter = HelloWorldExample("bolt://localhost:7687", "neo4j", "neo")
greeter.print_greeting("hello, world")
greeter.close()
When I run this code I get this error.

Your error does indicate a bit different code:
Traceback (most recent call last):
File "/Users/j/projects/neotest/neo.py", line 25, in <module>
greeter = HelloWorldExample("bolt://localhost:7687", "neo4j", "neo4j")
Here it shows that you initiated the HelloWorldClass with password "neo4j" instead of "neo"

How to fix "google.api_core.exceptions.ServiceUnavailable: 503 Connect Failed" when connected to Google cloud API

I want to use GOOGLE vision API,and I get the error 'google.api_core.exceptions.ServiceUnavailable: 503 Connect Failed'.
I get 503 error when connecting to Google vision API, and i have followed the instruction step by step. The link is as follows:
https://cloud.google.com/vision/docs/quickstart-client-libraries
I download my key file(json format) and ensure API is enabled.I set the environment variable and follow other instruction by putting the os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = r"/Users/a529157492/Desktop/application_default_credentials 2.json"
directly in the code.
However, i still get the error code.
import io
import os
from google.cloud import vision
from google.cloud.vision import types
from google.oauth2 import service_account
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] =
r"/Users/a529157492/Desktop/application_default_credentials 2.json"
client = vision.ImageAnnotatorClient()
file_name = os.path.abspath(r'/Users/a529157492/Desktop/demo-img.jpg')
with io.open(file_name, 'rb') as image_file:
content = image_file.read()
image = types.Image(content=content)
response = client.label_detection(image=image)
labels = response.label_annotations
print('Labels:')[enter image description here][1]
for label in labels:

AXL Python getLine using pattern instead of uuid does not work (CUCM 11.5)

I'm struggling with getting for example line info via getLine using pattern instead of uuid. According to getLine AXL schema for CUCM 11.5 it should be possible to choose either uuid or pattern as lookup criteria. The python (2.7) module that I'm using is suds-jurko 0.6.
Base code is as follows:
from suds.client import Client
import ssl
wsdl = 'file:///C:/Users/xyz/Documents/axlplugin/schema/current/AXLAPI.wsdl'
location = 'https://10.10.20.1/axl/'
username = '***'
password = '***'
ssl._create_default_https_context = ssl._create_unverified_context
client = Client(wsdl, location=location, username=username, password=password)
First of all, the proof that the pattern I want to use as a lookup string for getLine actually exists:
>>> line2 = client.service.listLine({'pattern': '1018'}, returnedTags={'description': ''})
>>> line2
(reply){
return =
(return){
line[] =
(LLine){
_uuid = "{1EC56035-6B5D-283A-4DF0-EFEFA01FCEFF}"
description = None
},
}
}
Then, I try getLine using uuid which works well:
>>> line5 = client.service.getLine('1EC56035-6B5D-283A-4DF0-EFEFA01FCEFF')
>>> line5
(reply){
return =
(return){
line =
(RLine){
_uuid = "{1EC56035-6B5D-283A-4DF0-EFEFA01FCEFF}"
pattern = "1018"
description = None
usage = "Device"
routePartitionName = ""
aarNeighborhoodName = ""
----Rest omitted for brevity---
Now, if I try to use pattern, not uuid, I have following error:
line6 = client.service.getLine({'pattern': '1018'}, {'routePartitionName': ''})

Am I using incorrect syntax or it's actually not possible to use pattern however schema file states differently?
Additionally, I'm wondering how to extract only uuid value from for example listLine method, is it possible via python axl?

In Suds, if memory serves me correctly, you can use keyword arguments for get and update requests.
For example:
resp = client.service.getLine(routePartitionName='PT-ONCLUSTER', pattern='\+49301234567')
if that doesn't work, try:
resp = client.service.getLine({'routePartitionName': 'PT-ONCLUSTER', 'pattern': '\+49301234567'})
Or better yet, check out python-zeep instead. It's much faster and better maintained than suds. Some example code with Zeep:
# -*- coding: utf-8 -*-
from zeep import Client
from zeep.cache import SqliteCache
from zeep.transports import Transport
from zeep.exceptions import Fault
from zeep.plugins import HistoryPlugin
from requests import Session
from requests.auth import HTTPBasicAuth

from urllib3.exceptions import InsecureRequestWarning
from lxml import etree
disable_warnings(InsecureRequestWarning)
username = 'admin'
password = 'password'
# If you're not disabling SSL verification, host should be the FQDN of the server rather than IP
host = '10.1.1.1'
wsdl = 'file://C:/path/to/wsdl/AXLAPI.wsdl'

binding = "{http://www.cisco.com/AXLAPIService/}AXLAPIBinding"
# Create a custom session to disable Certificate verification.
# In production you shouldn't do this,
# but for testing it saves having to have the certificate in the trusted store.

session.verify = False
session.auth = HTTPBasicAuth(username, password)
transport = Transport(cache=SqliteCache(), session=session, timeout=20)

python SOAP with zeep, requests.exception: 403 client error

I was able to solve the issue by doing the following. The issue was caused by some firewall issues and the proxy not working.

session.trust_env = False
transport = Transport(session=session)
client = Client(wsdl=client_location, wsse=UsernameToken(usr, password, use_digest=True), transport=transport)

'proxies' : <proxy>,
'verify' : False,
}
jira = JIRA(options,basic_auth=basic_auth,validate=True)
should work.
I tried and it is working for me.
Make sure you have access to the project to acess the issue.
