我试图将我的数据集拆分为训练和测试数据集,但我收到此错误:
X_train,X_test,Y_train,Y_test = sklearn.cross_validation.train_test_split(X,df1['ENTRIESn_hourly'])
AttributeError Traceback (most recent call last)
<ipython-input-53-5445dab94861> in <module>()
----> 1 X_train,X_test,Y_train,Y_test = sklearn.cross_validation.train_test_split(X,df1['ENTRIESn_hourly'])
AttributeError: module 'sklearn' has no attribute 'cross_validation'
我怎么处理这个？
