tensorflow::ops::ScatterSub
#include <state_ops.h>
Subtracts sparse updates to a variable reference.
Summary
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 (negated) contributions add.
Requires updates.shape = indices.shape + ref.shape[1:]
.
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 subtract from
ref
.
Optional attributes (see Attrs
):
 use_locking: If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
Returns:
Output
: = Same asref
. Returned as a convenience for operations that want to use the updated values after the update is done.
