我正在尝试运行Apache Beam Python示例（例如https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/complete/game/user_score.py）。当我运行脚本时，我得到了
(py27) XXX-MBP:my_path$ python user_score.py --output /my_path/user_score_output

问题似乎与Oauth2client和获取访问令牌有关。我google了一下，人们正在谈论设置同意='提示'，但它是在要求用户同意的领域。这里我只是下载一个数据集。是否可以访问我的Google Cloud服务？其他程序可以将程序写入Google云端存储。我在看https://developers.google.com/identity/protocols/OAuth2，但我真的不明白我应该做什么......
