Class VariableSynchronization

Indicates when a distributed variable will be synced.

Class tf.compat.v1.VariableSynchronization
Class tf.compat.v2.VariableSynchronization
AUTO: Indicates that the synchronization will be determined by the current DistributionStrategy (eg. With MirroredStrategy this would be ON_WRITE).
NONE: Indicates that there will only be one copy of the variable, so there is no need to sync.
ON_WRITE: Indicates that the variable will be updated across devices every time it is written.
ON_READ: Indicates that the variable will be aggregated across devices when it is read (eg. when checkpointing or when evaluating an op that uses the variable).
