seed an RNG seed (a tensor with shape [2] and dtype int32 or int64). (When using XLA, only int32 is allowed.)
num optional, a positive integer or scalar tensor indicating the number of seeds to produce (default 2).

A tensor with shape [num, 2] representing num new seeds. It will have the same dtype as seed (if seed doesn't have an explict dtype, the dtype will be determined by tf.convert_to_tensor).
