The - To know more about the default RNG used in NumPy, named PCG, I recommend the [PCG paper](https://www.pcg-random.org/paper.html) which also contains lots of useful information about RNGs in general. The [pcg-random.org website](https://www.pcg-random.org) is also full of interesting information about RNGs. [^1]: If you only need a seed for reproducibility and do not need independence with respect to others, say for a unit test, a small seed is perfectly fine. + [^2]: A good RNG is expected to produce independent numbers for a given seed. However, the independence of sequences generated from two different seeds is not always guaranteed. For instance, it is possible that the sequence started with the second seed might quickly converge to an internal state also obtained by the first seed. This can result in both RNGs producing the same subsequent numbers, which would compromise the randomness expected from distinct seeds. + [^3]: Before knowing about `default_rng`, and before NumPy 1.17, I was using the scikit-learn function [`check_random_state`](https://scikit-learn.org/stable/modules/generated/sklearn.utils.check_random_state.html) which is of course heavily used in the scikit-learn codebase. While writing this post I discovered that this function is now available in [scipy](https://github.com/scipy/scipy/blob/62d2af2e13280d29781585aa39a3c5a5dfdfba17/scipy/_lib/_util.py#L231). A look at the docstring and/or the source code of this function will give you a good idea about what it does. The differences with `default_rng` are that `check_random_state` currently relies on `np.random.RandomState` and that when `None` is passed to `check_random_state` then the function returns the already existing global NumPy RNG. The latter can be convenient because if you fix the seed of the global RNG before in your script using `np.random.seed`, `check_random_state` returns the generator that you seeded. However, as explained above, this is not the recommended practice and you should be aware of the risks and the side effects. [^4]: Before 1.25 you need to get the `SeedSequence` from the RNG using the `_seed_seq` private attribute of the underlying bit generator: `rng.bit_generator._seed_seq`. You can then spawn from this `SeedSequence` to get child seeds that will result in independent RNGs.
