If `indices` is a permutation and `len(indices) == params.shape[0]` then
this operation will permute `params` accordingly.

`validate_indices`: DEPRECATED. If this operation is assigned to CPU, values in
`indices` are always validated to be within range. If assigned to GPU,
out-of-bound indices result in safe but unspecified behavior, which may include
raising an error.

        values every time they are called (for a given variable shape). For
        unseeded initializers (`seed=None`), a random seed will be created and
        assigned at initializer creation (different initializer instances get
        different seeds).
    *   An unseeded initializer will raise a warning if it is reused (called)
