I am training a DL model in Pytorch, and want to train my model in a deterministic way.
As written in this official guide, I set random seeds like this:
np.random.seed(0)
torch.manual_seed(0)

I want to generate a random seed in a predictable way.
I was hoping to do this
seed = 12345
prng_0 = random.Random(seed)
prng_1 = random.Random(prng_0.rand_int(0))
There, 0 is the lower bound, but...

I often use numpy.random.seed() for reproducibility of results. I also find it helpful when books/tutorials use it (e.g., np.random.seed(42)), so that people can reproduce things more easily.

Does torch.manual_seed include the operation of torch.cuda.manual_seed_all?
If yes, we can just use torch.manual_seed to set the seed. Otherwise we should call both functions.

I've created a very simple OpenAI gym (banana-gym) and wonder if / how I should implement env.seed(0).
See https://github.com/openai/gym/issues/250#issuecomment-234126816 for example.

For example, take an array of generated numbers and get the original seed.
