Hide all warnings in ipython

I need to produce a screencast of an ipython session, and to avoid confusing viewers, I want to disable all warnings emitted by warnings.warn calls from different packages. Is there a way to configure the ipythonrc file to automatically disable all such warnings?

I eventually figured it out. Place:

import warnings
warnings.filterwarnings('ignore')

inside ~/.ipython/profile_default/startup/disable-warnings.py. I'm leaving this question and answer for the record in case anyone else comes across the same issue.

Quite often it is useful to see a warning once. This can be set by:

warnings.filterwarnings(action='once')
