I was using this to reset the generator, in order to repeat the same sequence again for testing purposes.
In general, you should just pass in a new Generator that was created with the same seed. def function_to_test(rg): x = rg.standard_normal() ... SEED = 12345... rg = np.random.default_rng(SEED) function_to_test(rg) rg = npp.random.default_rng(SEED) function_to_test(rg) Resetting the state of the underlying BitGenerator in-place is possible, as Kevin showed, but if you can refactor your code so that there isn't a persistent Generator object between these runs, that's probably better. It's a code smell if you can't just pass in a fresh Generator; in general, it means that your code is harder to use, not just because we don't expose an in-place seed() method. -- Robert Kern
