# tensorflow::ops::ResourceScatterNdUpdate Class Reference

# tensorflow::ops::ResourceScatterNdUpdate

`#include <state_ops.h>`

Applies sparse `updates` to individual values or slices within a given.

## Summary

variable according to `indices`.

`ref` is a `https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` with rank `P` and `indices` is a `https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_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 `https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` of rank `Q-1+P-K` with shape:


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

<br />

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


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

<br />

The resulting update to ref would look like this:

```
[1, 11, 3, 10, 9, 6, 7, 12]
```

<br />

See `tf.scatter_nd` for more details about how to make updates to slices.

Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- ref: A resource handle. Must be from a VarHandleOp.
- indices: A [Tensor](https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor). Must be one of the following types: int32, int64. A tensor of indices into ref.
- updates: A [Tensor](https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor). Must have the same type as ref. A tensor of updated values to add to ref.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r2.7/api_docs/cc/struct/tensorflow/ops/resource-scatter-nd-update/attrs#structtensorflow_1_1ops_1_1_resource_scatter_nd_update_1_1_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.

<br />

Returns:

- the created `https://www.tensorflow.org/versions/r2.7/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation`
