# tensorflow:: ops:: SegmentProd

 #include <math_ops.h> 

Computes the product along segments of a tensor.

## Summary

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]]


Args:

• scope: A Scope object
• segment_ids: A 1-D tensor whose size is equal to the size of  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  , the number of segments.
