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.

No, am trying to access the main function in vnf_manager.py which resides under vnfmanager folder. If you look into the repo - (github.com/TCS-TelcoCloud/vnfmanager) we have vnfmanager folder, under than vnf_manager file exists.

Ah sorry, I missed that file. import vnfmanager.vnf_manager works here (in a virtualenv), it just errors because of all the missing dependencies like yaml, eventlet, oslo and so on. The package author should fix that. That package has a ton of dependencies, and none of them is properly declared. If you use virtualenv and install all the dependencies yourself, maybe the package will work.
