facebook的python business sdk使用了一个保留关键字-workaround?

在Python3.7中,

from facebookads.adobjects.adlabel import AdLabel 

结果在

Traceback (most recent call last):
  File "/Users/mohan/growth-tools/facebook-experiment/main.py", line 4, in <module>
    from facebookads.adobjects.adlabel import AdLabel
  File "/Users/mohan/growth-tools/facebook-experiment/venv/lib/python3.7/site-packages/facebookads/adobjects/adlabel.py", line 22, in <module>
    from facebookads.adobjects.abstractcrudobject import AbstractCrudObject
  File "/Users/mohan/growth-tools/facebook-experiment/venv/lib/python3.7/site-packages/facebookads/adobjects/abstractcrudobject.py", line 564
    params=None, async=False, include_summary=True,
                     ^
SyntaxError: invalid syntax

问题是,我认为,从Python3.7开始,Async已经成为一个保留关键字。有什么办法可以让我继续使用这个sdk吗?
