<br />

    tf.errors.OutOfRangeError(
        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.

| ## 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. <br /> > [!NOTE] > **Note:** If the failed op was synthesized at runtime, e.g. a `Send` or `Recv` op, there will be no corresponding [`tf.Operation`](https://www.tensorflow.org/versions/r2.0/api_docs/python/tf/Operation) object. In that case, this will return `None`, and you should instead use the [`tf.errors.OpError.node_def`](https://www.tensorflow.org/versions/r2.0/api_docs/python/tf/errors/OpError#node_def) to discover information about the op. |
