出现 No module named ‘sklearn.cross_validation’ 错误

原因：sklearn中已经废弃cross_validation,将其中的内容整合到model_selection
操作：cross_validation改成model_selection，比如将

from sklearn.cross_validation import KFold
from sklearn.cross_validation import cross_val_score

改为

from sklearn.model_selection import KFold
from sklearn.model_selection import cross_val_score
