UPD: looks like pre-compiled libraries published on pypi and used from pypi install are not working on all linux systems because builded with shared libraries, you need to build package yourself, but build system was also broken. see #18 merge request, until merged use command below to install:

./venv/bin/pip install --upgrade 'git+https://github.com/vgavro/extractnet@fix/pip_build'

this works for me, thanks! Also I installed g++ libxml2-dev git to make the build.
