Ошибка импорта из подпроцесса _args_from_interpreter_flags при использовании с Google App Engine

Я уже проверил другой пост в SO , в котором упоминалась та же проблема здесь , но это не ответ на мою проблему.Это связано с тем, что исключение было вызвано локальным модулем с таким же именем «подпроцесс», о чем сообщает OP в комментарии к ответу.

Ниже приводится описание моей проблемы:

Когда япопытался вызвать функцию в моем проекте Google App Engine, который использует boto3 для генерации presigned_url, я получил следующее: 

ERROR    2019-06-14 00:30:47,272 webapp2.py:1552] cannot import name _args_from_interpreter_flags

Однако, если я попробовал это локально в IDLE, ImportError: 

$ python
Python 2.7.10 (default, Feb 22 2019, 21:55:15)

Type "help", "copyright", "credits" or "license" for more information.
>>> from subprocess import _args_from_interpreter_flags
>>>

В некоторых других местах некоторые предполагают, что это может быть проблема с циклической ссылкой, и, возможно, ее можно исправить, предварительно импортировав _args_from_interpreter_flags.

Однако, когда я попробовал этомой локальный сервер GAE мгновенно вышел из строя:

Можете ли вы предложить способ решения проблемы?
