简介: 成功解决DataConversionWarning: A column-vector y was passed when a 1d array was expected. Please change 解决问题 sklearn\utils\validation.py:578: DataConversionWarning: A column-vector y was passed when a 1d array
DataConversionWarning: A column-vector y was passed when a 1d array was expected. Please change 数据转换警告:当需要一维数组时,传递了列向量y。请将Y的形状更改为(n_samples,),例如使用ravel()。 y = column_or_1d(y, warn=True) 解决方法 该问题是警告信息,不处理亦可运行程序,只需理解一下即可!建...

DataConversionWarning: A column-vector y was passed when a 1d array was expected. Please change the shape of y to (n_samples, ), for example using ravel(). return f(**kwargs) 原因是,在训练时的y_train的格式不对。 用ravel转换下数据格式即可运行。

Perhaps we could keep the best of the two worlds by implementing Christoph's suggestion and adding 1D vector-specific aliases when we known at code-writing-time that we are dealing with vectors: we already have operator()(index) we already have size() ...
