The properties module doesn't exist anymore and unfortunately the user
guide linked on the NetworKit website isn't up to date. There are
changes to come. For the time being, please consider this updated user
which also briefly introduces the new profiling module, the successor of
the properties module. There is a notebook
dedicated to it.

This warning is new to me both in respect to NetworKit but also in
general. Just to rule out any misunderstandings: You cloned the
repository or downloaded a copy of it and used the "pip3 install -e
./"-command in the directory, where NetworKit's setup.py lies after you
installed it via "pip3 install networkit"? And you only get this warning
when importing networkit?
I might add, that I once "confused" my Python instance by mixing up
different pip commands. One solution may be to manually remove all
traces of NetworKit installations from the
/path/to/python/site-packages/. That includes the folders networkit/,
networkit-4.0.1-py3.5.egg-info/ and the file
_NetworKit.cpython-35m-x86_64-linux-gnu.so (exact names may differ).
Then you can try to install NetworKit once again.
Until this issue is fixed, keep in mind that it's only a warning. I get
warnings from packages such as matplotlib, but it still works fine.
Hope this helps,
