解决问题

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)

解决思路

这个模块是0.18版本不支持的model_selection模块的所有类和函数的重构移动。还要注意，新的CV迭代器的接口与此模块的接口不同。此模块将在0.20中删除。本模块将被删除，deprecationwarning）0.20。

很清楚，是版本问题，升级导致的不兼容！

解决办法

将机器学习库的cross_validation 改为model_selection即可！

大功告成！
