    Sep 8, 2022 · Convert a 1D array to a 2D Numpy array using reshape. This package consists of a function called numpy.reshape which is used to convert a 1-D array into a 2-D array of required dimensions (n x m). This function gives a new required shape without changing the data of the 1-D array.

    You can arrange the same data contained in numbers in arrays with a different number of dimensions: The array with the shape (8,) is one-dimensional (1D), and the array with the shape (2, 2, 2) is three-dimensional (3D). Both have the same data as the original array, numbers.

    Can We Reshape Into any Shape? Yes, as long as the elements required for reshaping are equal in both shapes. We can reshape an 8 elements 1D array into 4 elements in 2 rows 2D array but we cannot reshape it into a 3 elements 3 rows 2D array as that would require 3x3 = 9 elements.

    We use the reshape() function to reshape a 1D array into a 2D array. For example, import numpy as np. array1 = np.array([1, 3, 5, 7, 2, 4, 6, 8]) # reshape a 1D array into a 2D array # with 2 rows and 4 columns . result = np.reshape(array1, (2, 4)) print(result) Run Code. Output. [[1 3 5 7] [2 4 6 8]]
