`#include <state_ops.h>`

Applies sparse addition to individual values or slices in a Variable.

`ref`

is a `Tensor`

with rank `P`

and `indices`

is a `Tensor`

of rank `Q`

.

`indices`

must be integer tensor, containing indices into `ref`

. It must be shape `[d_0, ..., d_{Q-2}, K]`

where `0 < K <= P`

.

The innermost dimension of `indices`

(with length `K`

) corresponds to indices into elements (if `K = P`

) or slices (if `K < P`

) along the `K`

th dimension of `ref`

.

`updates`

is `Tensor`

of rank `Q-1+P-K`

with shape:

[d_0, ..., d_{Q-2}, ref.shape[K], ..., ref.shape[P-1]]

For example, say we want to add 4 scattered elements to a rank-1 tensor to 8 elements. In Python, that addition would look like this:

ref = tf.Variable([1, 2, 3, 4, 5, 6, 7, 8], use_resource=True) indices = tf.constant([[4], [3], [1], [7]]) updates = tf.constant([9, 10, 11, 12]) add = tf.scatter_nd_add(ref, indices, updates) with tf.Session() as sess: print sess.run(add)

The resulting update to ref would look like this:

[1, 13, 3, 14, 14, 6, 7, 20]

See `tf.scatter_nd`

for more details about how to make updates to slices.

Arguments:

- scope: A Scope object
- ref: A resource handle. Must be from a VarHandleOp.
- indices: A Tensor. Must be one of the following types: int32, int64. A tensor of indices into ref.
- updates: A Tensor. Must have the same type as ref. A tensor of values to add to ref.

Optional attributes (see `Attrs`

):

- use_locking: An optional bool. Defaults to True. If True, the assignment will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

Returns:

- the created
