I also had a similar error in Ubuntu 16.04, Django 1.11, using systemd.

My problem was that I had split my settings out into separate files; ie: instead of having all settings in project/settings.py, I have a few settings files like project/settings/dev.py.

I had to update DJANGO_SETTINGS_MODULE in the project/wsgi.py file from:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")  

to

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")

then gunicorn worked.
