ScatterNdSub

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

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]]
 

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)
 

[1, -9, 3, -6, -4, 6, 7, -4]

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