tff.framework.FederatingStrategy

View source on GitHub

The abstract interface federating strategies must implement.

tff.framework.FederatingStrategy(
    executor: 'FederatingExecutor'
)

A FederatingStrategy defines the logic for how a FederatingExecutor handles federated types and federated intrinsics, specificially:

• which federated intrinsics are implemented
• how federated types and federated intrinsics are implemented
• how federated values are represented in the execution stack
• how work is delegated to the target executors
• which placements are implemented

Args
executor	A FederatingExecutor to use to handle unplaced types, computations, and processing.

Raises
TypeError	If executor is not a FederatingExecutor.
