Raised when an operation iterates past the valid input range.

Inherits From: OpError

    node_def, op, message

This exception is raised in "end-of-file" conditions, such as when a tf.QueueBase.dequeue operation is blocked on an empty queue, and a tf.QueueBase.close operation executes.


  • error_code: The integer error code that describes the error.
  • message: The error message that describes the error.
  • node_def: The NodeDef proto representing the op that failed.
  • op: The operation that failed, if known.

    N.B. If the failed op was synthesized at runtime, e.g. a Send or Recv op, there will be no corresponding tf.Operation object. In that case, this will return None, and you should instead use the tf.errors.OpError.node_def to discover information about the op.
