How to reshape an array in Python using Numpy?

Question

I have a (10,) array I want to reshape in (1,10)

I did the following (u being my array)

import numpy as np

u = u.reshape(-1,1).T

but it does not work, any advice ?

Answer 1

As mentioned by Chris in his comment you simply want to reshape the array by fixing the number of rows to one and let Python figure out the other dimension:

u=u.reshape(1, -1)

Answer 2

I think @Chris has mentioned well in the comment, you can try out

I have tried out the scenario

>>> import numpy as np
>>> u = np.zeros((10))

>>> u.shape
(10,)
>>> u.T
array([0., 0., 0., 0., 0., 0., 0., 0., 0., 0.])
>>> u = u.reshape(1, -1)
>>> u.shape
(1, 10)
>>> u.T
array([[0.],
   [0.],
   [0.],
   [0.],
   [0.],
   [0.],
   [0.],
   [0.],
   [0.],
   [0.]])

I think for your case u.reshape(1, -1) would do your work.
