Method reduce_sum

tensorflow/python/ops/parallel_for/pfor.py:1034–1046

Performs a sum reduction on `x` across pfor iterations. Note that this currently may not work inside a control flow construct. Args: x: an unvectorized Tensor. Returns: A Tensor that has same rank as `x`. The value is the sum of the values of `x` across the pfor itera
