pyrtid.utils.check_random_state

pyrtid.utils.check_random_state(seed)

Turn seed into a np.random.RandomState instance.

Parameters

seed ({None, int, numpy.random.Generator, numpy.random.RandomState}, optional) – If seed is None (or np.random), the numpy.random.RandomState singleton is used. If seed is an int, a new RandomState instance is used, seeded with seed. If seed is already a Generator or RandomState instance then that instance is used.

Returns

seed – Random number generator.

Return type

{numpy.random.Generator, numpy.random.RandomState}
