Specifies whether operations are executed synchronously or asynchronously.

TensorFlow can execute operations synchronously or asynchronously. If asynchronous execution is enabled, operations may return "non-ready" handles.

When enable is set to None, an appropriate value will be picked automatically. The value picked may change between TensorFlow releases.

enable Whether operations should be dispatched synchronously. Valid values:

  • None: sets the system default.
  • True: executes each operation synchronously.
  • False: executes each operation asynchronously.
