#include <math_ops.h>
Computes the product along segments of a tensor.
Read the section on segmentation for an explanation of segments.
Computes a tensor such that \(output_i = data_j\) where the product is over j
such that segment_ids[j] == i
.
If the product is empty for a given segment ID i
, output[i] = 1
.
For example:
c = tf.constant([[1,2,3,4], [4, 3, 2, 1], [5,6,7,8]]) tf.segment_prod(c, tf.constant([0, 0, 1])) # ==> [[4, 6, 6, 4], # [5, 6, 7, 8]]
Arguments:
data
's first dimension. Values should be sorted and can be repeated.Returns:
Output
: Has same shape as data, except for dimension 0 which has size k
