tensorflow:: ops:: Barrier

#include <data_flow_ops.h>

Defines a barrier that persists across different graph executions.

Summary

A barrier represents a key-value map, where each key is a string, and each value is a tuple of tensors.

At runtime, the barrier contains 'complete' and 'incomplete' elements. A complete element has defined tensors for all components of its value tuple, and may be accessed using BarrierTakeMany . An incomplete element has some undefined components in its value tuple, and may be updated using BarrierInsertMany .

Args:

  • scope: A Scope object
  • component_types: The type of each component in a value.

Optional attributes (see Attrs ):

  • shapes: The shape of each component in a value. Each shape must be 1 in the first dimension. The length of this attr must be the same as the length of component_types.
  • capacity: The capacity of the barrier. The default capacity is MAX_INT32, which is the largest capacity of the underlying queue.
  • container: If non-empty, this barrier is placed in the given container. Otherwise, a default container is used.
  • shared_name: If non-empty, this barrier will be shared under the given name across multiple sessions.
