Module object has no attribute 'argpaser' ---- Python

Question

I'm having an error on a python file. What it does is to get acces to an specific google API. OAuth2.0. But that's not the wrong part. The wrong part takes part of argparse (Retriving arguments from console by adding --something="").

Here's my code:

import argparse
import os
import pprint
import sys
import time
import httplib2

from apiclient import discovery
from oauth2client import file
from oauth2client import tools 
from oauth2client import client


# Time to wait (in seconds) between successive checks of training status.
SLEEP_TIME = 10


# Declare command-line flags.
argparser = argparse.ArgumentParser(add_help=False)
argparser.add_argument('object_name',
                     help='Full Google Storage path of csv data (ex bucket/object)')
argparser.add_argument('id',
                     help='Model Id of your choosing to name trained model')
#argparser.add_argument('action');


def print_header(line):
  '''Format and print header block sized to length of line'''
  header_str = '='
  header_line = header_str * len(line)
  print '\n' + header_line
  print line
  print header_line


def main(argv):

  parent_parsers = [tools.argparser]
  parent_parsers.extend(parents)
  parser = argparse.ArgumentParser(
        description=doc,
        formatter_class=argparse.RawDescriptionHelpFormatter,
        parents=parent_parsers)
  flags = parser.parse_args(argv[1:])

  scope='https://www.googleapis.com/auth/prediction'

  client_secrets = os.path.join(os.path.dirname(__file__),
                                'client_secrets.json')
  flow = client.flow_from_clientsecrets(client_secrets,
      scope=scope,
      message=tools.message_if_missing(client_secrets))

  storage = file.Storage('prediction.dat')
  credentials = storage.get()

  if credentials is None or credentials.invalid:
    credentials = tools.run_flow(flow, storage, flags)
    http = credentials.authorize(http = httplib2.Http())
    service = discovery.build('prediction', 'v1.6', http=http)


  try:
    papi = service.trainedmodels()
    print_header('Fetching list of first ten models')
    result = papi.list(maxResults=10).execute()
    print 'List results:'
    pprint.pprint(result)

  except client.AccessTokenRefreshError:
    print ("The credentials have been revoked or expired, please re-run"
      "the application to re-authorize")


if __name__ == '__main__':
  main(sys.argv)

On this line--> parent_parsers = [tools.argparser] I'm having that error:

line 75, in main parent_parsers = [tools.argparser] AttributeError: 'module' object has no attribute 'argparser'

The tools.py file is that one:

I don't understand the meaning of the error, it may be an import issue but I don't know. Thanks!

You need to make sure the oauth tools are setup properly:

python setup_oauth2client.py install

it's in the base directory
