By reshaping we can add or remove dimensions or change number of elements in each dimension. Reshape From 1-D to 2-D. Example Get your own Python Server. Convert the following 1-D array with 12 elements into a 2-D array. The outermost dimension will have 4 arrays, each with 3 elements: import numpy as np.
In this tutorial, you'll learn how to use NumPy reshape() to rearrange the data in an array. You'll learn to increase and decrease the number of dimensions and to configure the data in the new array to suit your requirements.

Jan 20, 2022 · In order to reshape a numpy array we use reshape method with the given array. In this example we will reshape the 1-D array of shape (1, n) to 2-D array of shape (N, M) here M should be equal to the n/N there for N should be factor of n.
Reshape 1D Array to 2D Array in NumPy. 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) Output [[1 3 5 7] [2 4 6 8]]
