# tensorflow:: ops:: ResourceScatterNdAdd

``` #include <state_ops.h> ```

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

## Summary

``` 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.

Args:

• 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 ``` Operation ```
