Splits a seed into n derived seeds.
tfp.substrates.numpy.random.split_seed(
seed, n=2, salt=None, name=None
)
See https://github.com/tensorflow/probability/blob/main/PRNGS.md
for details.
Args:
seed: The seed to split; may be an int, an (int, int) tuple, or a
Tensor. int seeds are converted to Tensor seeds using
tf.random.stateless_uniform stateful sampling. Tuples are converted to Tensor.
n: The number of splits to return. In TensorFlow, if n is an integer, this
function returns a list of seeds and otherwise returns a Tensor of
seeds. In JAX, this function always returns an array of seeds.
salt: Optional str salt to mix with the seed.
name: Optional name to scope related ops.

If n is a Python int, a tuple of seed values is returned. If
n is an int Tensor, a single Tensor of shape [n, 2] is returned. A
single such seed is suitable to pass as the seed argument of the
tf.random.stateless_* ops.
