Convert a 1D array to a 2D Numpy array using numpy.reshape
Here, we are using np.reshape to convert a 1D array to 2 D array. You can divide the number of elements in your array by ncols.
Python3
import numpy as nparr = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])# np.reshape(A,(-1,ncols))B = np.reshape(arr, (-1, 2))print('2D Numpy array: \n', B) |
Output:
2D Numpy array: [[ 1 2] [ 3 4] [ 5 6] [ 7 8] [ 9 10]
Convert a 1D array to a 2D Numpy array
Here we will learn how to convert 1D NumPy to 2D NumPy Using two methods. Numpy is a Python package that consists of multidimensional array objects and a collection of operations or routines to perform various operations on the array and processing of the array.
