我在一个python文件上遇到错误。它所做的是访问特定的谷歌API。OAuth2.0。但这并不是错误的部分。错误的部分占用了argparse的一部分（通过添加--something="从控制台检索参数）。
这是我的代码：
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print ("The credentials have been revoked or expired, please re-run"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)
在这行-->parent_parsers = [tools.argparser]上，我出现了错误：
第75行，主parent_parsers=[tools.argparsers]AttributeError:"module"对象没有属性"argparser"
tools.py文件就是这样一个文件：

我不明白这个错误的含义，它可能是一个重要的问题，但我不知道。谢谢
您需要确保oauth工具设置正确：
python setup_oauth2client.py install
它在基本目录中
