我已经检查过我的六个版本是最新版本(版本=“1.10.0”)
import sklearn
sklearn.version
@H_403_40@
‘0.17.1’
我发现sklearn文件夹中没有文件夹名称“model_selection”.但是https://github.com/scikit-learn/scikit-learn/tree/3078d7d611329c46777d4004a1185a3626558efe/sklearn中有这个文件夹.
安装dev版本后
$pip install git git：//github.com/scikit-learn/scikit-learn.git
已成功安装scikit-learn-0.18.dev0

import sklearn

根据此version的文档,“model_selection”包不存在.它确实存在于dev version.这应该是它抱怨的原因.
