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:
