Replicator(key, graph_item, config, cluster)¶
Used to perform in-graph replication on a computational graph.
That is, Replicator is used to create _n_ replicas of a tf.Graph, with all replicas being stored in a new tf.Graph and delineated with name scopes.
This also handles ControlFlowContexts, updating variable and gradient information, etc.
Replicate the entire graph as many times as num_replica.
graph_item – the original graph item
Returns: The new graph item
Apply the Kernel transformation.
