-// Returns the complex conjugate of a complex number.
+// Gather slices from `params` into a Tensor with shape specified by `indices`.
 //
-// Given a tensor `input` of complex numbers, this operation returns a tensor of
-// complex numbers that are the complex conjugate of each element in `input`. The
-// complex numbers in `input` must be of the form \\(a + bj\\), where *a* is the
-// real part and *b* is the imaginary part.
+// `indices` is an K-dimensional integer tensor, best thought of as a
+// (K-1)-dimensional tensor of indices into `params`, where each element defines a
+// slice of `params`:
 //
-// The complex conjugate returned by this operation is of the form \\(a - bj\\).
+//     output[i_0, ..., i_{K-2}] = params[indices[i0, ..., i_{K-2}]]
 //
-// For example:
+// Whereas in @{tf.gather} `indices` defines slices into the first
+// dimension of `params`, in `tf.gather_nd`, `indices` defines slices into the
+// first `N` dimensions of `params`, where `N = indices.shape[-1]`.
+//
+// The last dimension of `indices` can be at most the rank of
+// `params`:
+//
+//     indices.shape[-1] <= params.rank
+//
+// The last dimension of `indices` corresponds to elements
+// (if `indices.shape[-1] == params.rank`) or slices
+// (if `indices.shape[-1] < params.rank`) along dimension `indices.shape[-1]`
+// of `params`.  The output tensor has shape
+//
+//     indices.shape[:-1] + params.shape[indices.shape[-1]:]
+//
+// Note that on CPU, if an out of bound index is found, an error is returned.
+// On GPU, if an out of bound index is found, a 0 is stored in the
+// corresponding output value.
+//
+// Some examples below.
+//
+// Simple indexing into a matrix:
+//
+// ```python
+//     indices = [[0, 0], [1, 1]]
+//     params = [['a', 'b'], ['c', 'd']]
+//     output = ['a', 'd']

+//     params = [['a', 'b'], ['c', 'd']]
+//     output = [['c', 'd'], ['a', 'b']]
 // ```
-// # tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j]
-// tf.conj(input) ==> [-2.25 - 4.75j, 3.25 - 5.75j]
+//
+// Indexing into a 3-tensor:

+//     indices = [[1]]

-// Generate a single randomly distorted bounding box for an image.

-// Bounding box annotations are often supplied in addition to ground-truth labels

-// its content, i.e. *data augmentation*. This Op outputs a randomly distorted
-// localization of an object, i.e. bounding box, given an `image_size`,
-// `bounding_boxes` and a series of constraints.
-//
-// The output of this Op is a single bounding box that may be used to crop the
-// original image. The output is returned as 3 tensors: `begin`, `size` and
-// `bboxes`. The first 2 tensors can be fed directly into `tf.slice` to crop the
-// image. The latter may be supplied to `tf.image.draw_bounding_boxes` to visualize
-// what the bounding box looks like.
-//
-// Bounding boxes are supplied and returned as `[y_min, x_min, y_max, x_max]`. The
-// bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and
-// height of the underlying image.
-//
-// For example,
-//
-// ```python
-//     # Generate a single distorted bounding box.
-//     begin, size, bbox_for_draw = tf.image.sample_distorted_bounding_box(
-//         tf.shape(image),
-//         bounding_boxes=bounding_boxes)
-//
-//     # Draw the bounding box in an image summary.
-//     image_with_box = tf.image.draw_bounding_boxes(tf.expand_dims(image, 0),
-//                                                   bbox_for_draw)
-//     tf.summary.image('images_with_box', image_with_box)
-//
-//     # Employ the bounding box to distort the image.
-//     distorted_image = tf.slice(image, begin, size)
-// ```
-//
-// Note that if no bounding box information is available, setting
