| Args | |
|---|---|
| tensors | The list or dictionary of tensors to enqueue. |
| batch_size | The new batch size pulled from the queue. |
| capacity | An integer. The maximum number of elements in the queue. |
| min_after_dequeue | Minimum number elements in the queue after a dequeue, used to ensure a level of mixing of elements. |
| keep_input | A bool Tensor. This tensor controls whether the input is added to the queue or not. If it is a scalar and evaluates True, thentensors are all added to the queue. If it is a vector and enqueue_manyis True, then each example is added to the queue only if the corresponding value in keep_input is True. This tensor essentially acts as a filtering mechanism. |
| num_threads | The number of threads enqueuing tensor_list. |
| seed | Seed for the random shuffling within the queue. |
| enqueue_many | Whether each tensor in tensor_list is a single example. |
| shapes | (Optional) The shapes for each example. Defaults to the inferred shapes for tensor_list. |
| allow_smaller_final_batch | (Optional) Boolean. If True, allow the final batch to be smaller if there are insufficient items left in the queue. |
| shared_name | (Optional) If set, this queue will be shared under the given name across multiple sessions. |
| name | (Optional) A name for the operations. |
| Returns |
|---|
| A list or dictionary of tensors with the types as tensors. |
| Raises | |
|---|---|
| ValueError | If the shapes are not specified, and cannot be inferred from the elements of tensors. |
