In a virtualenv, the import works here.

But there are other problems with that package. It has a lot of undeclared dependencies, and it mentions some vnfsvc_examples directory that does not exist. I'd contact the package author.

If you install all the dependencies, it seems to work:

virtualenv test
source test/bin/activate
pip install pastescript oslo.db oslo.messaging oslo.config eventlet pyyaml
python setup.py install
python -c "import vnfmanager.vnf_manager"

Note: you may need to install some additional compile-time dependencies first, like a compiler and the Python development headers. This is OS-specific. On a Debian-based Linux, try sudo apt-get install build-essential python-dev.

Do not manually install Python packages into your system-wide Python installation. It can break things in nasty ways. Your system-wide Python installation should be managed by your OS package manager. I.e. do not run pip or setup.py install as root. Instead, use virtualenv.
