Describe the bug
Deprecation warnings are generated for Pandas current usage of the pandas API.

/home/patrick/Programming/github/PrISUm/Strategy/venv/lib/python3.6/site-packages/pyfakefs/fake_filesystem_unittest.py:575: FutureWarning: The pandas.np module is deprecated and will be removed from pandas in a future version. Import numpy directly instead

    def setUp(self):
        self.setUpPyfakefs()

    def test_parse_race(self):
        print(os.getcwd())
        return True

Sorry, missed this issue for some reason... thanks for the report!
We do not use the deprecated API, as far as I can see. This seems to be a side effect of inspecting the loaded module - we have to deprecate any warnings. I thought we already did this, but obviously we do this not everywhere where needed.

@patrickdemers6 - shall be fixed in master now, please check!

I'm sure it's great! Is there an easy way to use the latest version in my project when a release hasn't been created?

You can install it from source:

pip install git+https://github.com/jmcgeheeiv/pyfakefs

I can confirm there aren't any warnings shown when running my test. Thanks for resolving this so quickly!
