AccumulatorTakeGradient

public final class AccumulatorTakeGradient

Extracts the average gradient in the given ConditionalAccumulator.

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.

Constants

Constant Value: "AccumulatorTakeGradient"

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public Output<T> average ()

The average of the accumulated gradients.

public static AccumulatorTakeGradient<T> create (Scope scope, Operand<TString> handle, Operand<TInt32> numRequired, Class<T> dtype)

Factory method to create a class wrapping a new AccumulatorTakeGradient operation.

Parameters

scope	current scope
handle	The handle to an accumulator.
numRequired	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

• a new instance of AccumulatorTakeGradient
