Divides a variable reference by sparse updates.
This operation computes
# Scalar indices
ref[indices, ...] /= updates[...]
# Vector indices (for each i)
ref[indices[i], ...] /= updates[i, ...]
# High rank indices (for each i, ..., j)
ref[indices[i, ..., j], ...] /= updates[i, ..., j, ...]
This operation outputs `ref` after the update is done.
This makes it easier to chain operations that need to use the reset value.
Duplicate entries are handled correctly: if multiple `indices` reference the same location, their contributions divide.
Requires `updates.shape = indices.shape + ref.shape[1:]` or `updates.shape = []`.

Public Methods
public Output <T> asOutput ()
Returns the symbolic handle of a tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
public static ScatterDiv <T> create ( Scope scope, Operand <T> ref, Operand <U> indices, Operand <T> updates, Options... options)
Factory method to create a class wrapping a new ScatterDiv operation.
Parameters
scope | current scope |
---|---|
ref | Should be from a `Variable` node. |
indices | A tensor of indices into the first dimension of `ref`. |
updates | A tensor of values that `ref` is divided by. |
options | carries optional attributes values |
Returns
- a new instance of ScatterDiv
public Output <T> outputRef ()
= Same as `ref`. Returned as a convenience for operations that want to use the updated values after the update is done.
public static ScatterDiv.Options useLocking (Boolean useLocking)
Parameters
useLocking | If True, the operation will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. |
