[FIXED] Changing shape of multidimensional array in Python

Issue

I have an array B with shape (1,9,1). Is it possible to convert into a new array B1 with shape (1,3,3)? The desired output is attached.

import numpy as np

B=np.array([[[0.67873113],
              [1.24442563],
              [0.02109   ],
              [0.76788408],
              [2.00615422],
              [3.07375839],
              [1.037729  ],
              [5.03294753],
              [0.0105    ]]])
print("B shape =",B.shape)

The desired output is

B1=np.array([[[0.67873113,1.24442563,0.02109   ],
             [0.76788408,2.00615422,3.07375839],
             [1.037729,5.03294753,0.0105    ]]])

B1 shape = (1, 3, 3)

Solution

You can just reshape it. See here

B.reshape((1,3,3))

>>> array([[[0.67873113, 1.24442563, 0.02109   ],
        [0.76788408, 2.00615422, 3.07375839],
        [1.037729  , 5.03294753, 0.0105    ]]])
