sklearn: Turning off warnings

Question

When I'm fitting sklearn's LogisticRegression using a 1 column python pandas DataFrame (not a Series object), I get this warning:

/Library/Python/2.7/site-packages/sklearn/preprocessing/label.py:125:          DataConversionWarning: A column-vector y was passed when a 1d array was  expected. Please change the shape of y to (n_samples, ), for example using  ravel(). y = column_or_1d(y, warn=True) 

I know I could easily advert this warning in my code, but how can I turn off these warnings?

Answer 1

You can use this:

import warnings from sklearn.exceptions import DataConversionWarning warnings.filterwarnings(action='ignore', category=DataConversionWarning)
