AccumulatorTakeGradient

tensorflow C++ API

tensorflow::ops::AccumulatorTakeGradient

Extracts the average gradient in the given ConditionalAccumulator.

Summary

The op 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 returns the 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 an accumulator.
  • 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 : The average of the accumulated gradients.

Constructor

  • AccumulatorTakeGradient(const ::tensorflow::Scope & scope, ::tensorflow::Input handle, ::tensorflow::Input num_required, DataType dtype).

Public attributes

  • tensorflow::Output average.

Argument:

  • Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
  • Input handle: connect Input node.
  • Input num_required: connect Input node.
  • DataType dtype : connect Input node.

Return:

  • Output average.: Output operation of AccumulatorTakeGradient object.

Result:

  • std::vector(Tensor) product_result : Returned object of executed result by calling session.
