How to Convert 1-D NumPy Array Into a 3-D NumPy Array

In this example we will show how to convert the 1-D NumPy array into a 3-D one in Python.

Source Code

import numpy as np

n = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])

reshape_n = n.reshape(2, 2, 3)

print(reshape_n)

Output:

[[[ 1  2  3]
  [ 4  5  6]]

 [[ 7  8  9]
  [10 11 12]]]
