[`tf.compat.v1.raw_ops.PriorityQueue`](https://www.tensorflow.org/api_docs/python/tf/raw_ops/PriorityQueue)

<br />

    tf.raw_ops.PriorityQueue(
        shapes,
        component_types=[],
        capacity=-1,
        container='',
        shared_name='',
        name=None
    )

Note that the PriorityQueue requires the first component of any element
to be a scalar int64, in addition to the other elements declared by
component_types. Therefore calls to Enqueue and EnqueueMany (resp. Dequeue
and DequeueMany) on a PriorityQueue will all require (resp. output) one extra
entry in their input (resp. output) lists.

| ## Args ||
|---|---|
| `shapes` | A list of shapes (each a [`tf.TensorShape`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/TensorShape) or list of `ints`). The shape of each component in a value. The length of this attr must be either 0 or the same as the length of component_types. If the length of this attr is 0, the shapes of queue elements are not constrained, and only one element may be dequeued at a time. |
| `component_types` | An optional list of `tf.DTypes`. Defaults to `[]`. The type of each component in a value. |
| `capacity` | An optional `int`. Defaults to `-1`. The upper bound on the number of elements in this queue. Negative numbers mean no limit. |
| `container` | An optional `string`. Defaults to `""`. If non-empty, this queue is placed in the given container. Otherwise, a default container is used. |
| `shared_name` | An optional `string`. Defaults to `""`. If non-empty, this queue will be shared under the given name across multiple sessions. |
| `name` | A name for the operation (optional). |
