tf.raw_ops.ResourceScatterAdd

Adds sparse updates to the variable referenced by resource.

tf.raw_ops.ResourceScatterAdd(
    resource, indices, updates, 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, ...]

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 = [].
