Applies sparse updates to a variable reference.
tf.raw_ops.ScatterUpdate(
ref, indices, updates, use_locking=True, name=None
)
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.
If values in ref
is to be updated more than once, because there are
duplicate entries in indices
, the order at which the updates happen
for each value is undefined.
Requires updates.shape = indices.shape + ref.shape[1:]
or updates.shape = []
.
