#include <state_ops.h>
Applies sparse subtraction between updates
and 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 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 subtract 4 scattered elements from a rank-1 tensor with 8 elements. In Python, that subtraction 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]) sub = tf.scatter_nd_sub(ref, indices, updates) with tf.Session() as sess: print sess.run(sub)
The resulting update to ref would look like this:
[1, -9, 3, -6, -4, 6, 7, -4]
See tf.scatter_nd
for more details about how to make updates to slices.
Arguments:
Optional attributes (see Attrs
):
Returns:
Output
: Same as ref. Returned as a convenience for operations that want to use the updated values after the update is done. Constructors and Destructors | |
