时,我有一个scikit学习安装版本0.18.1 ::DeprecationWarning在0.18.1进口GridSearchCV

$ PIP卸载-y SciPy的scikit学习 $ PIP安装SciPy的scikit学习

当我进口GridSearchCV我得到一个奇怪的DeprecationWarning ::

(venv2) :~/$ cat warn.pyy 
from sklearn.grid_search import GridSearchCV 
import sklearn as sk 
print(sk.__version__) 

如果我运行它,我得到::

(venv2) :~/$ python warn.py 
/home/n/venv2/local/lib/python2.7/site-packages/sklearn/cross_validation.py:44: 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. 
    "This module will be removed in 0.20.", DeprecationWarning)

    DeprecationWarning) 

0.18.1 

如何避免此弃用警告?

弃用警告有点令人误解。 GridSearchCV不会像@abccd建议的那样离开,它将被移到scikit-learn中的不同子模块中。

相反的:

from sklearn.grid_search import GridSearchCV 

用途:

from sklearn.model_selection import GridSearchCV
