Extracts the average sparse gradient in a SparseConditionalAccumulator.
tf.raw_ops.SparseAccumulatorTakeGradient( handle, num_required, dtype, name=None )
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.
Args | |
---|---|
handle | A Tensor of type mutable string . The handle to a SparseConditionalAccumulator. |
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 tuple of Tensor objects (indices, values, shape). | |
indices | A Tensor of type int64 . |
values | A Tensor of type dtype . |
shape | A Tensor of type int64 . |
