这个是我的代码片段

# -*- coding: utf-8 -*-
import os
import string
import random
import tempfile

import unittest


from qiniu import Auth, set_default, etag, PersistentFop, build_op, op_save
from qiniu import put_data, put_file, put_stream
from qiniu import BucketManager, build_batch_copy, build_batch_rename, build_batch_move, build_batch_stat, build_batch_delete
from qiniu import urlsafe_base64_encode, urlsafe_base64_decode



access_key = 'xxxxxxxxxxxxxxxxx'
secret_key = 'xxxxxxxxxxxxxxxx'
bucket_name = 'mypython'
q=qiniu.Auth(access_key,secret_key)


key='dd.txt'
data='hello'

token = q.upload_token(bucket_name)
ret, info = qiniu.put_data(token, key, data)
print(info)
assert ret['key'] == key

然后我的sdk安装方式是在github中下载的sdk,然后使用
python setup.py install
来安装的
可是运行的时候总是提示
from qiniu import Auth, set_default, etag, PersistentFop, build_op, op_save
ImportError: cannot import name Auth
这个错误.
可是这个可以在命令行成功导入,不知道为什么.希望各位大神帮忙解答下呀.
