问：

如何在python中过滤特定模块的特定警告？

MWE

ERROR:

cross_val_score(model, df_Xtrain,ytrain,cv=2,scoring='r2')

/usr/local/lib/python3.6/dist-packages/sklearn/linear_model/_ridge.py:148: LinAlgWarning: Ill-conditioned matrix (rcond=3.275e-20): result may not be accurate.
  overwrite_a=True).T

我的尝试

import warnings
warnings.filterwarnings(action='ignore',module='sklearn')

cross_val_score(model, df_Xtrain,ytrain,cv=2,scoring='r2')

This works but I assume it ignores all the warnings such as deprecation warnings. I would like to exclude only LinAlgWarning

import warnings
warnings.filterwarnings(action='ignore', category='LinAlgWarning', module='sklearn')

有没有像这个过滤器特定的警告这样的方法？
