+    Document Question Answering pipeline using any `AutoModelForDocumentQuestionAnswering`. The inputs/outputs are
+    similar to the (extractive) question answering pipeline; however, the pipeline takes an image (and optional OCR'd
+    words/boxes) as input instead of text context.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> document_qa = pipeline(model="impira/layoutlm-document-qa")
+    >>> document_qa(
+    ...     image="https://huggingface.co/spaces/impira/docquery/resolve/2359223c1837a7587402bda0f2643382a6eefeab/invoice.png",

+    ... )
+    [{'score': 0.425, 'answer': 'us-001', 'start': 16, 'end': 16}]
+    ```
+
+    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)
+
+    This document question answering pipeline can currently be loaded from [`pipeline`] using the following task

+        Answer the question(s) given as inputs by using the document(s). A document is defined as an image and an
+        optional list of (word, box) tuples which represent the text in the document. If the `word_boxes` are not
+        provided, it will use the Tesseract OCR engine (if available) to extract the words and boxes automatically for
+        LayoutLM-like models which require them as input. For Donut, no OCR is run.
+
+        You can invoke the pipeline several ways:
+
+        - `pipeline(image=image, question=question)`
+        - `pipeline(image=image, question=question, word_boxes=word_boxes)`
+        - `pipeline([{"image": image, "question": question}])`
+        - `pipeline([{"image": image, "question": question, "word_boxes": word_boxes}])`
+
+        Args:
+            image (`str` or `PIL.Image`):
+                The pipeline handles three types of images:
+
+                - A string containing a http link pointing to an image
+                - A string containing a local path to an image
+                - An image loaded in PIL directly
+
+                The pipeline accepts either a single image or a batch of images. If given a single image, it can be
+                broadcasted to multiple questions.
+            question (`str`):
+                A question to ask of the document.
+            word_boxes (`List[str, Tuple[float, float, float, float]]`, *optional*):
+                A list of words and bounding boxes (normalized 0->1000). If you provide this optional input, then the
+                pipeline will use these words and boxes instead of running OCR on the image to derive them for models
+                that need them (e.g. LayoutLM). This allows you to reuse OCR'd results across many invocations of the
+                pipeline without having to re-run it each time.
+            top_k (`int`, *optional*, defaults to 1):
+                The number of answers to return (will be chosen by order of likelihood). Note that we return less than
+                top_k answers if there are not enough options available within the context.
+            doc_stride (`int`, *optional*, defaults to 128):
+                If the words in the document are too long to fit with the question for the model, it will be split in
+                several chunks with some overlap. This argument controls the size of that overlap.
+            max_answer_len (`int`, *optional*, defaults to 15):
+                The maximum length of predicted answers (e.g., only answers with a shorter length are considered).
+            max_seq_len (`int`, *optional*, defaults to 384):
+                The maximum length of the total sentence (context + question) in tokens of each chunk passed to the
+                model. The context will be split in several chunks (using `doc_stride` as overlap) if needed.
+            max_question_len (`int`, *optional*, defaults to 64):
+                The maximum length of the question after tokenization. It will be truncated if needed.
+            handle_impossible_answer (`bool`, *optional*, defaults to `False`):
+                Whether or not we accept impossible as an answer.
+            lang (`str`, *optional*):
+                Language to use while running OCR. Defaults to english.
+            tesseract_config (`str`, *optional*):
+                Additional flags to pass to tesseract while running OCR.
+            timeout (`float`, *optional*, defaults to None):
+                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and
+                the call may block forever.
+
+        Return:
+            A `dict` or a list of `dict`: Each result comes as a dictionary with the following keys:
+
+            - **score** (`float`) -- The probability associated to the answer.
+            - **start** (`int`) -- The start word index of the answer (in the OCR'd version of the input or provided
+              `word_boxes`).
+            - **end** (`int`) -- The end word index of the answer (in the OCR'd version of the input or provided
+              `word_boxes`).
+            - **answer** (`str`) -- The answer to the question.

+class MaskGenerationPipeline(ChunkPipeline):
+    """
+    Automatic mask generation for images using `SamForMaskGeneration`. This pipeline predicts binary masks for an
+    image, given an image. It is a `ChunkPipeline` because you can seperate the points in a mini-batch in order to
+    avoid OOM issues. Use the `points_per_batch` argument to control the number of points that will be processed at the
+    same time. Default is `64`.
+
+    The pipeline works in 3 steps:
+        1. `preprocess`: A grid of 1024 points evenly separated is generated along with bounding boxes and point
+           labels.
+            For more details on how the points and bounding boxes are created, check the `_generate_crop_boxes`
+            function. The image is also preprocessed using the `image_processor`. This function `yields` a minibatch of
+            `points_per_batch`.
+
+        2. `forward`: feeds the outputs of `preprocess` to the model. The image embedding is computed only once.
+            Calls both `self.model.get_image_embeddings` and makes sure that the gradients are not computed, and the
+            tensors and models are on the same device.
+
+        3. `postprocess`: The most important part of the automatic mask generation happens here. Three steps
+            are induced:
+                - image_processor.postprocess_masks (run on each minibatch loop): takes in the raw output masks,
+                  resizes them according
+                to the image size, and transforms there to binary masks.
+                - image_processor.filter_masks (on each minibatch loop): uses both `pred_iou_thresh` and
+                  `stability_scores`. Also
+                applies a variety of filters based on non maximum suppression to remove bad masks.
+                - image_processor.postprocess_masks_for_amg applies the NSM on the mask to only keep relevant ones.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> generator = pipeline(model="facebook/sam-vit-base", task="mask-generation")
+    >>> outputs = generator(
+    ...     "http://images.cocodataset.org/val2017/000000039769.jpg",
