Extracts the average gradient in the given ConditionalAccumulator.
tf.raw_ops.AccumulatorTakeGradient(
handle, num_required, dtype, name=None
)
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.
Args |
handle
|
A Tensor of type mutable string . The handle to an accumulator.
|
num_required
|
A Tensor of type int32 .
Number of gradients required before we return an aggregate.
|
dtype
|
A tf.DType from: tf.float32, tf.float64, tf.int32, tf.uint8, tf.int16, tf.int8, tf.complex64, tf.int64, tf.qint8, tf.quint8, tf.qint32, tf.bfloat16, tf.uint16, tf.complex128, tf.half, tf.uint32, tf.uint64 .
The data type of accumulated gradients. Needs to correspond to the type
of the accumulator.
|
name
|
A name for the operation (optional).
|
Returns |
A Tensor of type dtype .
