I intended to use python to scale aws instances up and down.
I'm not inside any virtual environment at the moment.
why is it being thrown, and how do I get across it?
It is even mentioned here on the official documentation : https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/autoscaling.html#AutoScaling.Client.set_desired_capacity
The official document is for the latest version, not your too old version. Upgrade your boto3 package to the latest. The most recent version is 1.9.243.
The problem turns out to be a silly one.
boto3 has moved around the various functions.
set_desired_capacity is no longer part of 'elbv2' .
It is part of 'autoscaling' https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/autoscaling.html#AutoScaling.Client.set_desired_capacity
While 'describe_target_health' is still part of the former https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/elbv2.html?highlight=elb#ElasticLoadBalancingv2.Client.describe_target_health.
Updating
client = boto3.client('elbv2')
to
client = boto3.client('autoscaling')
has solved my problem.

I am trying to upload JSON file into a new container on Azure blob Storage account.
I use Microsoft quick guide
Currently my code looks like this:
>import os, uuid
>from azure.storage.blob import BlobServiceClient, BlobClient, ContainerClient
>connect_str = os.getenv('AZURE_STORAGE_CONNECTION_STRING')
So far It's works OK but when I add this line
>blob_service_client = BlobServiceClient.from_connection_string(connect_str)
I get an error message:
>(base) "`my file path`"
Traceback (most recent call last):
File "`my file path`", line 14, in <module>
blob_service_client = BlobServiceClient.from_connection_string(connect_str)

I had wrote the same code on my PC and about a month ago I moved to Mac OS. I thought I did all the relevant adjustments, but apparently not.
Since this mac is completely new I think I missing a few packages or maybe hav the wrong versions of the packages.
I am attaching pip list:
azure-common 1.1.27
azure-core 1.12.0
azure-nspkg 3.0.2
azure-storage 0.36.0
azure-storage-blob 12.9.0
Thank you!
Your environment variable is probably not found.
Try this code
connect_str = os.environ['AZURE_STORAGE_CONNECTION_STRING']
It should raise a KeyError or return None.
I think you should be sure the variable is really read or that its value is not None.
I cannot seem to create and attach a file to an item in podio using the pypodio client, which is the python wrapper for PODIO's API. I am trying to get the file id but keep on getting the error. I am using Python 3.6.0
My code is
`path = os.getcwd()`
`filename="system_information"`
`filepath = path + "\\system_information.txt"`
`filedata=open(filepath)`
uploading_response = pcbapp.Files.create(filename,filedata)
I get an error shown below,
File "c:\users\nipun.arora\src\podio-py\pypodio2\encode.py", line 317, in get_headers
boundary = urllib.quote_plus(boundary)
AttributeError: module 'urllib' has no attribute 'quote_plus'
That's might be because there is no urllib.quote_plus in python3. Can you try running same code in python2?
Or, Saltstack + docker-py AttributeError: 'RecentlyUsedContainer' object has no attribute 'lock'
I have been digging into this issue to no avail. I'm trying to use SaltStack to manage my docker images/containers but ran into this problem.
Initially I was using the salt state docker.running but that presented as the command does not exist. When I changed the state to docker.running, I got the traceback I posted over at that GitHub issue:

with self.pools.lock:
AttributeError: 'RecentlyUsedContainer' object has no attribute 'lock'
Started: 09:33:42.873628
Duration: 22.115 ms
After searching Google a bit more and coming up with nothing, I went ahead and started reading the source.
After reading unixconn.py and realizing that RecentlyUsedContainer was coming from urllib3, I went and tracked down the source for that and discovered that there was a _lock attribute that was changed to lock a while ago. That seemed strange.
I looked closer at the imports and realized that unixconn.py was attempting to use requests' built-in urllib3 and then falling back to the stand alone urllib3. So I checked out the requests urllib3 and found that it did, indeed have the _lock -> lock change. But it was newer than my version of requests. So I upgraded requests and tried again. Still no dice - same AttributeError.
Now things start to get weird.
In order to get information back to my salt master, I started mucking with the docker-py and urllib3 code on my salt minion. At first I raised exceptions with urllib3.__file__ to make sure I was using the right file. But occasionally the file name that it would return was in a file and a folder that did not exist. Usually it was displaying /usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/_collections.pyc, but when I would delete that file thinking that maybe the .pyc being cached was causing a problem it would still say that was the __file__, even though it didn't exist.
Then I discovered inspect.getfile. And I got the same bizarre behavior - I could delete the .pyc file and yet inspect.getfile(self.pools) would return the non-existent file.
To make life even better, I've added
raise Exception('Pining for the Fjords')
to
/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/_collections.py
At the end of the RecentlyUsedContainer.__init__. Yet that exception does not raise.
And I have just confirmed that something is in fact lying to me, because despite changing unixconn.py
def get_connection(self, url, proxies=None):
import inspect
r = RecentlyUsedContainer(10)
raise Exception(inspect.getfile(r.__class__) + '\n' + r.__doc__)
which returns /usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/_collections.pyc, when I go edit that .pyc and modify the RecentlyUsedContainer's docstring I get the original docstring.
And finally, when I edit /usr/lib/python2.7/dist-packages/urllib3/_collections.pyc and change it's docstring, (or the same path but _collections.py instead)...
I still get the same docstring!
Why is the wrong code getting executed here, and how can I find out where it is so I can fix the problem?
So I finally figured out the problem:
It did have something to do with salt. For some reason the way the salt minion imported the docker-py library it did some sort of... partial hold on the imports. I suspect that what was happening was that salt was re-importing just the docker-py library specifically so when I would make changes to those files the changes would show up.
However, since the Python import mechanism will search for pre-imported modules first the urllib3 code was never re-imported.
Ultimately all that is required is to restart the salt minion:
salt 'my-minion' cmd.run "nohup /bin/sh -c 'sleep 10 && salt-call --local service.restart salt-minion'"
I am trying to use the Google Drive API to download publicly available files however whenever I try to proceed I get an import error.
For reference, I have successfully set up the OAuth2 such that I have a client id as well as a client secret , and a redirect url however when I try setting it up I get an error saying the object has no attribute urllen
>>> from apiclient.discovery import build
>>> from oauth2client.client import OAuth2WebServerFlow
>>> flow = OAuth2WebServerFlow(client_id='not_showing_client_id', client_secret='not_showing_secret_id', scope='https://www.googleapis.com/auth/drive', redirect_uri='https://www.example.com/oauth2callback')
>>> auth_uri = flow.step1_get_authorize_url()
>>> code = '4/E4h7XYQXXbVNMfOqA5QzF-7gGMagHSWm__KIH6GSSU4#'
>>> credentials = flow.step2_exchange(code)
And then I get the error:
Traceback (most recent call last):

Any help would be appreciated, also would someone mind enlightening me as to how I instantiate a drive_file because according to https://developers.google.com/drive/web/manage-downloads, I need to instantiate one and I am unsure of how to do so.
Edit: So I figured out why I was getting the error I got before. If anyone else is having the same problem then try running.
sudo pip install -I google-api-python-client==1.3.2
However I am still unclear about the drive instance so any help with that would be appreciated.
Edit 2: Okay so I figured out the answer to my whole question. The drive instance is just the metadata which results when we use the API to search for a file based on its id
So as I said in my edits try the sudo pip install and a file instance is just a dictionary of meta data.
I am trying to include the SUDS library in a Python project through Google App Engine.
My code tries the following:
from suds.client import Client
from suds.wsse import *
And, once I've deployed on GAE, I encounter the following error:
File ".../myfile.py", line 13, in <module>
from suds.client import Client
File ".../suds/__init__.py", line 154, in <module>
import client
File ".../suds/client.py", line 25, in <module>
import suds.metrics as metrics
AttributeError: 'module' object has no attribute 'suds'
I've been looking around for a little while, and it seems like SUDS is workable with GAE. I added the fixes outlined here, but that doesn't seem to be the problem. It seems like App Engine doesn't even get to that point.
Any info or suggestions?
I'm using Python 2.7 and SUDS 0.4.
Have you tried doing a simple import suds.client? Also make sure you include the suds folder in your application as App Engine doesn't include it by default. I hope that helps.
