Coverage.py warning: Module _ was previously imported, but not measured.

[gebn]

I see this warning for the project module and all app modules I'm testing. I assume Django is importing all of these before coverage is run, hence the warnings, however is there a way of hiding them, given it is to be expected?

django: 1.10.2
nose: 1.3.7
django-nose: 1.4.4
coverage: 4.2

What command are you using to run coverage tests? coverage recommends something like:

coverage run ./manage.py test
