My emacs-jedi won't find the package

In mine .emacs

I have (setenv "PYTHONPATH" "/home/username/python-packages")

where I have packages that I use and develop. Unfortunately, emacs-jedi

it won't find them and it won't autocomplete them. How can I debug it and solve the problem?

For reference, here is mine jedi:show-setup-info
