tensorflow::ops::SparseAccumulatorTakeGradient

#include <data_flow_ops.h>

Extracts the average sparse gradient in a SparseConditionalAccumulator.

Summary

The op will blocks until sufficient (i.e., more than num_required) gradients have been accumulated. If the accumulator has already aggregated more than num_required gradients, it will return its average of the accumulated gradients. Also automatically increments the recorded global_step in the accumulator by 1, and resets the aggregate to 0.

Arguments:

  • scope: A Scope object
  • handle: The handle to a SparseConditionalAccumulator.
  • num_required: Number of gradients required before we return an aggregate.
  • dtype: The data type of accumulated gradients. Needs to correspond to the type of the accumulator.

Returns:

  • Output indices: Indices of the average of the accumulated sparse gradients.
  • Output values: Values of the average of the accumulated sparse gradients.
  • Output shape: Shape of the average of the accumulated sparse gradients.
