No module named 'sklearn.cross_validation'

markdown ## No module named 'sklearn.cross_validation' 參考: [https://blog.csdn.net/qq_35962520/article/details/85295228](https://blog.csdn.net/qq_35962520/article/details/85295228) 在機器學習時會遇到這個報錯，原因是

cross_validation

這個包裹，已經移到

model_selection

所以只要將原先的 ``` from sklearn.cross_validation import train_test_split ``` 更改成 ``` from sklearn.model_selection import train_test_split ```
