出现问题

D:\python2.7\lib\site-packages\sklearn\cross_validation.py:41: 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)

解决

from sklearn.model_selection import train_test_split

其实就是cross_validation引起的

import matplotlib.pyplot as plyimport numpy as npfrom sklearn.model_selection import train_test_splitfrom sklearn import datasets,linear_model,discriminant_analysis
