Computes the mean along sparse segments of a tensor.
tf.compat.v2.sparse.segment_mean( data, indices, segment_ids, num_segments=None, name=None )
Read the section on segmentation for an explanation of segments.
segment_ids can have rank less than
dimension, selecting a subset of dimension 0, specified by
segment_ids is allowed to have missing ids, in which case the output will
be zeros at those indices. In those cases
num_segments is used to determine
the size of the output.
