Have you installed the packages listed on the installation wiki?

 apt-get install gir1.2-goocanvas-2.0 python-gi python-gi-cairo python-pygraphviz python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython ipython3  

I think we may have a lingering problem with the Ubuntu 16.04 (Linux Mint 18) version of these packages, because others have reported a similar problem.  It works for me on Ubuntu 18.04, but I haven't been able yet to check with 16.04.
