  r"""Generates skip-gram token and label paired Tensors from the input tensor.

  See docs for the public-facing skip_gram_sample() Python op for more details.

  Args:
    input_tensor: A `Tensor`.
    min_skips: A `Tensor` of type `int32`.
    max_skips: A `Tensor` of type `int32`.
    start: A `Tensor` of type `int32`.
    limit: A `Tensor` of type `int32`.
    emit_self_as_target: A `Tensor` of type `bool`.
    seed: An optional `int`. Defaults to `0`.
    seed2: An optional `int`. Defaults to `0`.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (tokens, labels).

    tokens: A `Tensor`. Has the same type as `input_tensor`.
    labels: A `Tensor`. Has the same type as `input_tensor`.
