Python DeprecationWarning 类型错误

 

 

from sklearn.cross_validation import train_test_split

# 使用sklearn.cross_valiation里的train_test_split模块用于分割数据

使用上述导入时,出现DeprecationWarning警告的类型错误:
该类型的警告大多属于版本更新时,所使用的方法过时的原因,可以在该方法的说明处查找替换的方法
 
DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20.
  "This module will be removed in 0.20.", DeprecationWarning)
 

 

 

大意为该模块在0.18版本中被弃用,支持所有重构的类和函数都被移动到的model_selection模块。另请注意,新的CV迭代器的接口与本模块的接口不同。 此模块将在0.20中删除。
 

 

 

将“ from sklearn.cross_validation import train_test_split
改为“ from sklearn. model_selection  import train_test_split
