ModuleNotFoundError: No module named 'sklearn.cross_validation'

此文首发于我的个人博客：报错解决-ModuleNotFoundError No module named ‘sklearn.cross_validation’ — zhang0peter的个人博客

在使用anaconda写Python代码，运行
from sklearn.cross_validation import train_test_split
时报错：
ModuleNotFoundError: No module named ‘sklearn.cross_validation’
上网查阅资料后发现问题：
sklearn.cross_validation是sklearn老版本的模块，新版本都迁移到了
sklearn.model_selection
修改代码为
from sklearn.model_selection import train_test_split
即可正常运行
