为什么3D纽比阵列是这样打印的?

similar 但更多的是关于编程语言之间的差异,我仍然没有完全理解。我来解释一下。

假设我要创建一个3行(长度)、5列(宽度)和2个深度的3D数组。所以一个3x5x2矩阵。

import numpy as np
a = np.zeros(30).reshape(3, 5, 2)

[[[0. 0. 0. 0. 0.]  #We can still see three rows from top to bottom
  [0. 0. 0. 0. 0.]] #We can still see five columns from left to right

 [[0. 0. 0. 0. 0.]  #Depth values are shown underneath each other
  [0. 0. 0. 0. 0.]] 

 [[0. 0. 0. 0. 0.]
  [0. 0. 0. 0. 0.]]]

但是,当我打印这个数组时,它会像这样打印:

[[[0. 0.] #We can still see three rows from top to bottom,
  [0. 0.] #However columns now also appear from top to bottom instead of from left to right
  [0. 0.] #Depth values are now shown from left to right
  [0. 0.]
  [0. 0.]]

 [[0. 0.]
  [0. 0.]
  [0. 0.]
  [0. 0.]
  [0. 0.]]

 [[0. 0.]
  [0. 0.]
  [0. 0.]
  [0. 0.]
  [0. 0.]]]
