Raised when an operation or step is cancelled.
For example, a long-running operation (e.g.
tf.QueueBase.enqueue may be
cancelled by running another operation (e.g.
A step that is running such a long-running operation will fail by raising
The integer error code that describes the error.
The error message that describes the error.
NodeDef proto representing the op that failed.
The operation that failed, if known.
N.B. If the failed op was synthesized at runtime, e.g. a
Recv op, there will be no corresponding
object. In that case, this will return
None, and you should
instead use the
discover information about the op.
Operation that failed, or None.
