使用python时的警告消息

Question

我在运行SVM python代码时不断得到这个:

Warning (from warnings module):
  File "/usr/local/lib/python2.7/dist-packages/sklearn/cross_validation.py", line 44
    "This module will be removed in 0.20.", DeprecationWarning)
DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20.

Warning (from warnings module):
  File "/usr/local/lib/python2.7/dist-packages/sklearn/grid_search.py", line 43
    DeprecationWarning)
DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. This module will be removed in 0.20.

这条警告信息表示什么？

提前致谢

Answer 1

scikit-learn的最新稳定版本是0.18 http://scikit-learn.org/stable/

您使用的版本已弃用这些模块.
或者使用

    from sklearn.model_selection import train_test_split
