我有一个scikit-learn安装版本为0.18.1:
$ pip uninstall -y scipy scikit-learn $ pip install scipy scikit-learn
当我导入GridSearchCV时,会出现奇怪的DeprecationWarning:
(venv2) :~/$ cat warn.pyy
from sklearn.grid_search import GridSearchCV
import sklearn as sk
print(sk.__version__)
如果我运行它,我会得到:
(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
如何避免这个弃用警告?
