tensorflow::ops::ScatterMul
#include <state_ops.h>
Multiplies sparse updates into a variable reference.
Summary
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 multiply.
Requires updates.shape = indices.shape + ref.shape[1:] or updates.shape = [].
Arguments:
- scope: A Scope object
- ref: Should be from a
Variable node.
- indices: A tensor of indices into the first dimension of
ref.
- updates: A tensor of updated values to multiply to
ref.
Optional attributes (see Attrs):
- use_locking: If True, the operation 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.
