Why we are creating grad = np.zeros(([2],))

#1

please expln sir and also expln grad[0] and grad[1]

Hey @dhiru96027

We initialize our gradient vector grad by using grad = np.zeros((2,)). This creates a row vector that contains two values [0.,0.] both are zero.

The grad[0] and grad[1] are used to access the first and second values of the row vector grad.

We are creating grad to store the updated gradient value.
