How to obtain a gaussian filter in python

Question

I am using python to create a gaussian filter of size 5x5. I saw this post here where they talk about a similar thing but I didn\'t find the exact way to get equivalent python c

Hey, I think this might help you

import numpy as np
import cv2

def gaussian_kernel(dimension_x, dimension_y, sigma_x, sigma_y):
    x = cv2.getGaussianKernel(dimension_x, sigma_x)
    y = cv2.getGaussianKernel(dimension_y, sigma_y)
    kernel = x.dot(y.T)
    return kernel
g_kernel = gaussian_kernel(5, 5, 1, 1)
print(g_kernel)
