'Typing: How to specify shape of array

How can I specify the "typing shape" of an array?

I have a function that returns a numpy array of shape (2, 2):

import numpy as np
def some_function() -> np.ndarray:
    return np.array([[1, 2], [3, 4]])

I would like to specify the shape in the returning type.
