Got DeprecationWarning when running pytest in Python 3.7.3

I fixed the compatibility issue to run in Python 3.7.3 and still got below warning for reference:

env_3/lib/python3.7/site-packages/normalize/property/__init__.py:161
  /root/Tasks/watson-for-cybersecurity/env_3/lib/python3.7/site-packages/normalize/property/__init__.py:161: DeprecationWarning: inspect.getargspec() is deprecated since Python 3.0, use inspect.signature() or inspect.getfullargspec()
    args = inspect.getargspec(func)

env_3/lib/python3.7/site-packages/normalize/visitor.py:393
  /root/Tasks/watson-for-cybersecurity/env_3/lib/python3.7/site-packages/normalize/visitor.py:393: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
    grok_coll_types = (collections.Sequence, collections.Mapping)

Open issue here for reference and fix.

@johnklee Are you saying you got this warning after running normalize through 2to3 or futurize? Normalize is not currently Python 3 compatible, although we are working on that now.

[johnklee]

@rbm Partially right, I actually modify the locally installed version ("site-packages") to be Python3 compatible and then still got above DeprecationWarning. Just post here for reference and if there is a released version for Python3 without above warning, I will close this issue. Any suggestion is appreciated.

@johnklee Thanks. We're working on Python 3 support for normalize now, so we'll follow up when that's released. /cc @blalockma
