sklearn:关闭警告

Question

当我安装sklearnS" LogisticRegression使用1列蟒pandas DataFrame(不是Series对象),我得到这样的警告:

/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)

我知道我可以在我的代码中轻松地宣传此警告,但是如何关闭这些警告呢？

Answer 1

你可以用这个:

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

Answer 2

张贴在这里,

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    # Do stuff here
