A strategy for composing federated types and intrinsics in disjoint scopes.
Inherits From: FederatingStrategy
tff.framework.FederatedComposingStrategy(
executor: tff.framework.FederatingExecutor,
server_executor: tff.framework.Executor,
target_executors: List[tff.framework.Executor]
)
This strategy implements the FederatingStrategy interface and provides
logic for handling federated types and federated intrinsics on an underlying
collection of target executors. This strategy can be used in hierarchical
aggregation structures with federating executors handling disjoint scopes at
the leafs.
This strategy only supports the placements:
Args | |
|---|---|
executor
|
A federating_executor.FederatingExecutor to use to handle
unplaced types, computations, and processing.
|
server_executor
|
The parent executor to use for all processing at the parent, such as combining values from child executors, unplaced and server-side processing, etc. |
target_executors
|
The list of executors that manage disjoint scopes to combine in this executor, delegate to and collect or aggregate from. |
Raises | |
|---|---|
TypeError
|
If server_executor is not an executor_base.Executor or if
target_executors is not a list of executor_base.Executors.
