Using Jupyter Notebooks to make a lot of analysis on several dataframe sometime lead to some warnings (not errors) during the execution of the Python code.

I want to disable all warnings emitted by warnings.warn calls from different packages. Is there a way to configure the Notebook file to automatically disable all such warnings?

In Jupyter Notebooks, using Python engine, we can disable the warnings during the execution, placing the following code before the code:

import warnings
warnings.filterwarnings('ignore')

Or inside ~/.ipython/profile_default/startup/disable-warnings.py.

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

warnings.filterwarnings(action='once')
