WebMay 22, 2024 · The intended way to do what you want is. A = np.random.normal (0, 1, (3, 3)) This is the optional size parameter that tells numpy what shape you want returned (3 by 3 in this case). Your second way works too, because the documentation states. If size is None (default), a single value is returned if loc and scale are both scalars.
