Outputs a tensor containing the reduction across all input tensors.
tf.raw_ops.NcclAllReduce(
input, reduction, num_devices, shared_name, name=None
)
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.
