numpy.arrayh函数简介(博客资源备份)
This line of code is using the numpy library to reshape the validX array. The new shape of the array will have the same number of rows as the original but with an added dimension of size 1.
The first argument in the reshape function specifies the number of rows, which is the same as the original validX array.
The second argument is the number of columns, which is also the same as the original validX array.
The third argument is the size of the new added dimension, which is 1 in this case.
The result of this line of code will be a new array with the same number of rows and columns as the original validX array, but with an added dimension of size 1. This is often done when working with neural networks, where the third dimension is used to represent the number of input channels.
