Initial value:

= R"DOC(
Applies '{op}' to each segment of input tensor. In order to allow for more
efficient implementation of '{op}', the input segments have to be contiguous
and non-empty.

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.
