@Namespace(value="tensorflow::ops") @NoOffset @Properties(inherit=tensorflow.class) public class ScatterNdUpdate extends Pointer
updates to individual values or slices within a given
variable according to indices.
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 Kth
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 update 4 scattered elements to a rank-1 tensor to
8 elements. In Python, that update would look like this:
python
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)
tf.scatter_nd for more details about how to make updates to
slices.
See also tf.scatter_update and tf.batch_scatter_update.
Arguments:
* scope: A Scope object
* ref: A mutable Tensor. Should be from a Variable node.
* 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 updated
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:
* Output: Same as ref. Returned as a convenience for operations that want to
use the updated values after the update is done.| Modifier and Type | Class and Description |
