ModuleNotFoundError: No module named sklearn.cross_validation_modulenotfounderror: no module named 'sklearn.cros

Windows 10, python3.6版本，在执行from sklearn.cross_validation import cross_val_score时报错误信息：ModuleNotFoundError: No module named ‘sklearn.cross_validation’，具体如下：

ModuleNotFoundError Traceback (most recent call last)
in ()
8 from sklearn.decomposition import PCA
9 from sklearn.preprocessing import LabelEncoder, LabelBinarizer
—> 10 from sklearn.cross_validation import cross_val_score
11
12 from scipy import stats

ModuleNotFoundError: No module named 'sklearn.cross_validation
经查看，我当前scikit-learn版本号为0.21.3，在该版本中cross_validation 已经被遗弃，而应该改用model_selection，因此上面这条语句做如下更改即可。
from sklearn.model_selection import cross_val_score
快来试试吧！^-
