Initial value:

Applies '{op}' to each segment of input tensor. Segments need to be sorted and
contiguous. See also UnsortedSegment{op} that doesn't have this requirement.
SEGMENT_IDS is a vector that maps each of the first dimension slices of the
DATA to a particular group (segment). Values belonging to the same segment are
aggregated together.
The first dimension of the output is equal to the number of input segments,
i.e. `SEGMENT_IDS[-1]+1`. Other dimensions are inherited from the input tensor.
