I'm writing a python code to read email from mail server(neither google nor outlook) using imaplib2 package. I'm getting the following error with my code. Can anybody tell me how could I fix it. Do I need to use only port=993 and host=imap, if so how can I connect to the server I need to
import imaplib2
import base64
email_user = 'mailid'
email_pass = 'password'
email_server = 'ns21.interactivedns.com'
Mail = imaplib2.IMAP4_SSL(email_server, 995) # used this server and port since I'm trying to read mail contents from this server
Mail.login(email_user, email_pass)
Mail.select('Inbox')
type, messages = Mail.search(None, 'ALL')
Error I'm gertting:

I m trying to execute the folowing python code:
import logging
import sys
import docker, boto3
from base64 import b64decode
logging.basicConfig(stream=sys.stdout, level=logging.INFO)
LOCAL_REPOSITORY = '111111111111.dkr.ecr.us-east-1.amazonaws.com/my_repo:latest'
image = '111111111111.dkr.ecr.us-east-1.amazonaws.com/my_repo'
ecr_registry, _ = image.split('/', 1)
client = docker.from_env()
# Get login credentials from AWS for the ECR registry.
ecr = boto3.client('ecr')
response = ecr.get_authorization_token()
token = b64decode(response['authorizationData'][0]['authorizationToken'])
username, password = token.decode('utf-8').split(':', 1)
# Log in to the ECR registry with Docker.
client.login(username, password, registry=ecr_registry)
logging.info("loggined")
client.images.pull(image, auth_config={
username: username,
password: password
})
And got exception:

What is the problem? Why I can not pull image even after client.login call which happens wihtout any exeptions. What is the correct way to perform login and pull image from ECR repository and dockerpy?
This was happen due to - https://github.com/docker/docker-py/issues/2157
Deleting ~/.docker/config.json fixed the issue.
I am trying to connect python with hive data base .
Both are on different server.
hive resides on host xx.xxx.xxx.x and python is on my local system.
i am trying to use the below code , however its not working
import pyhive
from pyhive import hive
conn = hive.connect(host = 'xx.xxx.xx.xx', port = 8888, auth = 'KERBEROS', kerberos_service_name='adsuedscaihen01.aipcore.local', username ='user1', database = 'database1'
)
cur = conn.cursor()
cur.execute('SELECT * from table1')
result = cur.fetchall()
print(result)
while i run the above code , i am facing the below error:
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.7/site-packages/pyhive/hive.py", line 64, in connect

Is there a way to connect to django test database using connections?
I have tried
cursor = connections['test_name_of_main_db'].cursor()
and also specified the test db name in settings but I still receive errors:
Traceback (most recent call last):
File "/home/tets/4d/lib/python3.5/site-packages/django/db/utils.py", line 176, in ensure_defaults
conn = self.databases[alias]
KeyError: 'auto_tests'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/tets/healthware_server/component/medical/tests.py", line 72, in test_model_observation

raise ConnectionDoesNotExist("The connection %s doesn't exist" % alias)
django.db.utils.ConnectionDoesNotExist: The connection auto_tests doesn't exist
According to the docs:
The default test database names are created by prepending test_ to the value of each NAME in DATABASES.
But in your stacktrace the error says:
django.db.utils.ConnectionDoesNotExist: The connection auto_tests doesn't exist
Are you sure you are using the right alias? According to the error, it is looking for a database named auto_tests.
As another debugging step, you could print all the aliases during the test to see which ones are available
for alias in connections:
print(alias)
Of course, you could also try to use the default database and see if that works for you during the tests:
# note that it is 'connection' and not 'connections'
from django.db import connection
cursor = connection.cursor()
I am new to neo4j and want it to connect with Python. I am using neo4j version 3.0.3 and following this tutorial.
I put the code below in my Python file, I have changed the password, since my password is root:
from neo4j.v1 import GraphDatabase, basic_auth
driver = GraphDatabase.driver("bolt://localhost", auth=basic_auth(user = "neo4j", password = "root"))
session = driver.session()
session.run("CREATE (a:Person {name:'Bob'})")
result = session.run("MATCH (a:Person) RETURN a.name AS name")
for record in result:
print(record["name"])
session.close()
But on running it, I am getting following errors:
Traceback (most recent call last):
File "D:/Work/MySQL_neo4j_Importer/dumping_ingredients.py", line 3, in <module>
session = driver.session()
File "C:\Python27\lib\site-packages\neo4j\v1\session.py", line 148, in session
session = Session(self)
File "C:\Python27\lib\site-packages\neo4j\v1\session.py", line 461, in __init__
self.connection = connect(driver.host, driver.port, driver.ssl_context, **driver.config)
File "C:\Python27\lib\site-packages\neo4j\v1\connection.py", line 403, in connect
s = create_connection((host, port))
File "C:\Python27\lib\socket.py", line 557, in create_connection
for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 11004] getaddrinfo failed
I have also tried this StackOverFlow answer as well, but, the result remains same.
For Neo4j 1.8 / 1.9 / 2.0 / 2.1 / 2.2 / 2.3 you could use Py2neo.

I am trying to connect to hive using python 2(miniconda2 installation ).
Below is the code I am trying-
connection = hive.connect(host='psvlxihpnn1', port= '10000', authMechanism='KERBEROS', user='***',password='****', configuration={'krb_host': 'psvlxihpnn1', 'krb_service': 'ITEDM'} )
kerberos host is installed on the same host machine and has service name 'ITEDM'
Strangely, I am getting below error-
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/export/home/itedm/miniconda2/lib/python2.7/site-packages/pyhs2-0.6.0-py2.7.egg/pyhs2/__init__.py", line 7, in connect

I am not passing 'krbtgt' as user, not sure why this error is coming.
Thanks for any help.
This connection string will work as long as the user running the script has a valid kerberos ticket:
import pyhs2
with pyhs2.connect(host='beeline_host',
port=10000,
authMechanism="KERBEROS") as conn:
with conn.cursor() as cur:
print cur.getDatabases()
Username, password and any other configuration parameters are not passed through the KDC.
