numpy重塑具有特定顺序的数组 [英] Numpy reshape an array with specific order

问题描述

假设我有这个数组x:

x = array([1, 2, 3, 4, 5, 6, 7, 8])
x.shape = (8,1)

我想重塑它成为

array([[1, 3, 5, 7], 
       [2, 4, 6, 8]])

这是在x上的reshape(2，4)，但是很简单:

this is a reshape(2, 4) on x but in the straight forward way:

y = x.reshape(2,4)

y变为

array([[1, 2, 3, 4],
       [5, 6, 7, 8]])

那不是我想要的.有没有办法以这种特定方式转换数组?

and that's not what I want. Is there a way to transform the array in that specific way?

推荐答案

In[4]: x.reshape(4, 2).T
Out[4]: 
array([[1, 3, 5, 7],
       [2, 4, 6, 8]])
