原文,如下: I think you're using a new scikit-learn version and it's throwing an error because in the new version everything has to be a 2d matrix, even a single column or row. It even says: Reshape your data either using array.reshape(-1, 1) if your data has a single feature o...
Python将2d numpy数组与1d数组对应相乘 给定两个numpy数组,任务是将2d numpy数组与1d numpy数组相乘,每行对应numpy中的一个元素。让我们来讨论一下给定任务的一些方法。 方法#1:使用np.newaxis() # Python code to demonstrate # multiplication of 2d array # with 1
ValueError: Expected 2D array, got 1D array instead Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample. 在最新版本的sklearn中,所有的数据都应该是二维矩阵,哪怕它只是单独一行或一列,所以,要进行格式...

reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample. 解决思路: 值错误:应为二维数组,而得到的是一维数组: 使用array重新调整数据的形状。如果数据有单个功能或数组,则重新调整形状(-1,1)。如果数据包含单个示例,则重新调整形状(1,-1)。 解决...
