OSError: [Errno 47] Address family not supported by protocol family

[nicoaws]

Hi all.
I am getting a strange error when running docker-topo.

I am on MacOS HighSierra, Virtualenv + Python 3.7.
Installed via python setup.py install (inside the venv) as per your instructions.

Traceback (most recent call last):

i think you're hitting this
svinota/pyroute2#437
you can try running your topology with the default docker bridge driver, that should work
