scikit-learn - sklearn 的弃用警告

Question

我正在使用 cross_validation来自sklearn，

from sklearn.cross_validation import train_test_split

我收到以下警告:

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.

Answer 1

为避免这种情况，您只需更换:

from sklearn.cross_validation import train_test_split 

经过

from sklearn.model_selection import train_test_split

引用: skLearn

警告: DeprecationWarning:此模块在 0.18 版中已弃用，取而代之的是 model_selection 模块，所有重构的类和函数都移入其中。另请注意，新的 CV 迭代器的接口(interface)与此模块的接口(interface)不同。此模块将在 0.20 中删除。
