  Apply all migrations: sessions, admin, auth, default, contenttypes, hyperkitty
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration,
and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then
re-run 'manage.py migrate' to apply them.

ImportError: No module named 'psycopg2'

But:

pip install psycopg2
You are using pip version 6.1.1, however version 7.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): psycopg2 in
/usr/local/src/venv/lib/python2.7/site-packages


Please advice.
