SkLearning：关闭警告

问题描述

当我使用单列pythonpandasDataFrame(不是Series对象)调整sklearn的LogisticRegression时，收到以下警告：

/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)

我知道我可以很容易地在代码中显示此警告，但如何关闭这些警告？

解决方案

如发布的here，

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