NcclAllReduce

Outputs a tensor containing the reduction across all input tensors.
Outputs a tensor containing the reduction across all input tensors passed to ops
within the same `shared_name.
The graph should be constructed so if one op runs with shared_name value `c`,
then `num_devices` ops will run with shared_name value `c`. Failure to do so
will cause the graph execution to fail to complete.
input: the input to the reduction
data: the value of the reduction across all `num_devices` devices.
reduction: the reduction operation to perform.
num_devices: The number of devices participating in this reduction.
shared_name: Identifier that shared between ops of the same reduction.

asOutput
()
Returns the symbolic handle of a 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.
Factory method to create a class wrapping a new NcclAllReduce operation.
Returns
- a new instance of NcclAllReduce
