tf.errors.CancelledError

Raised when an operation or step is cancelled.

Inherits From: OpError

tf.errors.CancelledError(
    node_def, op, message
)

For example, a long-running operation (e.g. tf.QueueBase.enqueue may be cancelled by running another operation (e.g. tf.QueueBase.close, or by tf.Session.close. A step that is running such a long-running operation will fail by raising CancelledError.

Attributes

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.
