【原】成功解决ValueError: Supported target types are: (‘binary‘, ‘multiclass‘). Got ‘continuous‘ instead.

成功解决ValueError: Supported target types are: ('binary', 'multiclass'). Got 'continuous' instead.

解决问题

问题背景如下：

SKFold = StratifiedKFold(n_splits=cv_i,shuffle=True,random_state=123)

解决思路

值错误:支持的目标类型为:('binary'， 'multiclass')，需要用“continuous”替代。

解决方法

stratify只处理分类任务问题，对于回归任务，采用以下问题解决

将

from sklearn.model_selection import KFold,StratifiedKFold
n_SKFold = StratifiedKFold(n_splits=cv_i,shuffle=True,random_state=123)

替换为

from sklearn.model_selection import KFold,StratifiedKFold
n_SKFold = KFold(n_splits=n_folds ,shuffle=True,random_state=123)

哈哈，大功告成！
