tensorflow:: ops:: ScatterAdd

Adds sparse updates to 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 add.

Requires updates.shape = indices.shape + ref.shape[1:] or updates.shape = [] .

Args:

• 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 add to ref .

Optional attributes (see Attrs ):

• use_locking: If True, the addition 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.
