Python-ModuleNotFoundError:没有名为“sklearn.cross_validation”的模块[重复]

它必须与 cross_validation 子模块到 model_selection . 试着替代 到 型号选择

列车测试分离现在处于模式选择中。只需键入:

from sklearn.model_selection import train_test_split

应该有用的

我想交叉选择不再有效了。我们应该用模型选择来代替。你可以写下来跑, from sklearn.model_selection import train_test_split

确保你有 Anaconda 安装然后 create a virtualenv using conda

>>> from sklearn.cross_validation import train_test_split

sklearn.cross_validation 现在改为 sklearn.model_selection

from sklearn.model_selection import train_test_split

我想那会有用的。

sklearn.cross_validation

已更改为

sklearn.model_selection

https://scikit-learn.org/stable/modules/cross_validation.html

可能是因为sklearn.cross_validation被否决了。 请将sklearn.cross_validation替换为sklearn.model_selection

参考- https://github.com/amueller/scipy_2015_sklearn_tutorial/issues/60

from sklearn.model_selection import train_test_split

过去的: from sklearn.cross_validation (此软件包在0.18版本中已弃用,从0.20开始,它将更改为 from sklearn import model_selection

出席: 从sklearn导入模式选择

例2:

过去的: from sklearn.cross_validation import cross_val_score

出席: from sklearn.model_selection import cross_val_score

sklearn.cross_validation sklearn.model_selection

只是改变

sklearn.cross_validation

到

sklearn.model_selection

像这样更改代码

# from sklearn.cross_validation import train_test_split
from sklearn.model_selection import train_test_split

前一段时间不赞成使用交叉验证,请尝试使用模型选择将其关闭

如果有需要运行各种版本的代码,可以执行以下操作:

import sklearn
if sklearn.__version__ > '0.18':
    from sklearn.model_selection import train_test_split
else:
    from sklearn.cross_validation import train_test_split
