    Constructs a ColPali processor which wraps a PaliGemmaProcessor and special methods to process images and queries, as
    well as to compute the late-interaction retrieval score.

    [`ColPaliProcessor`] offers all the functionalities of [`PaliGemmaProcessor`]. See the [`~PaliGemmaProcessor.__call__`]
    for more information.

    Args:
        image_processor ([`SiglipImageProcessor`], *optional*):
            The image processor is a required input.
        tokenizer ([`LlamaTokenizerFast`], *optional*):
            The tokenizer is a required input.
        chat_template (`str`, *optional*): A Jinja template which will be used to convert lists of messages
            in a chat into a tokenizable string.
        visual_prompt_prefix (`str`, *optional*, defaults to `"Describe the image."`):
            A string that gets tokenized and prepended to the image tokens.
        query_prefix (`str`, *optional*, defaults to `"Question: "`):
            A prefix to be used for the query.

        Main method to prepare for the model either (1) one or several texts, either (2) one or several image(s). This method is a custom
        wrapper around the PaliGemmaProcessor's [`~PaliGemmaProcessor.__call__`] method adapted for the ColPali model. It cannot process
        both text and images at the same time.

        When preparing the text(s), this method forwards the `text` and `kwargs` arguments to LlamaTokenizerFast's
        [`~LlamaTokenizerFast.__call__`].
        When preparing the image(s), this method forwards the `images` and `kwargs` arguments to SiglipImageProcessor's
        [`~SiglipImageProcessor.__call__`].
        Please refer to the docstring of the above two methods for more information.

        Args:
            images (`PIL.Image.Image`, `np.ndarray`, `torch.Tensor`, `list[PIL.Image.Image]`, `list[np.ndarray]`, `list[torch.Tensor]`):
                The image or batch of images to be prepared. Each image can be a PIL image, NumPy array or PyTorch
                tensor. In case of a NumPy array/PyTorch tensor, each image should be of shape (C, H, W), where C is a
                number of channels, H and W are image height and width.
            text (`str`, `list[str]`, `list[list[str]]`):
                The sequence or batch of sequences to be encoded. Each sequence can be a string or a list of strings
                (pretokenized string). If the sequences are provided as list of strings (pretokenized), you must set
                `is_split_into_words=True` (to lift the ambiguity with a batch of sequences).
            return_tensors (`str` or [`~utils.TensorType`], *optional*):
                If set, will return tensors of a particular framework. Acceptable values are:

                - `'tf'`: Return TensorFlow `tf.constant` objects.
                - `'pt'`: Return PyTorch `torch.Tensor` objects.
                - `'np'`: Return NumPy `np.ndarray` objects.
                - `'jax'`: Return JAX `jnp.ndarray` objects.

        Returns:
            [`BatchFeature`]: A [`BatchFeature`] with the following fields:

            - **input_ids** -- List of token ids to be fed to a model.
            - **attention_mask** -- List of indices specifying which tokens should be attended to by the model (when
              `return_attention_mask=True` or if *"attention_mask"* is in `self.model_input_names` and if `text` is not
              `None`).
            - **pixel_values** -- Pixel values to be fed to a model. Returned when `images` is not `None`.

        Compute the late-interaction/MaxSim score (ColBERT-like) for the given multi-vector
        query embeddings (`qs`) and passage embeddings (`ps`). For ColPali, a passage is the
        image of a document page.

        Because the embedding tensors are multi-vector and can thus have different shapes, they
        should be fed as:
        (1) a list of tensors, where the i-th tensor is of shape (sequence_length_i, embedding_dim)
        (2) a single tensor of shape (n_passages, max_sequence_length, embedding_dim) -> usually
            obtained by padding the list of tensors.

        Args:
            query_embeddings (`Union[torch.Tensor, list[torch.Tensor]`): Query embeddings.
            passage_embeddings (`Union[torch.Tensor, list[torch.Tensor]`): Passage embeddings.
            batch_size (`int`, *optional*, defaults to 128): Batch size for computing scores.
            output_dtype (`torch.dtype`, *optional*, defaults to `torch.float32`): The dtype of the output tensor.
                If `None`, the dtype of the input embeddings is used.
            output_device (`torch.device` or `str`, *optional*, defaults to "cpu"): The device of the output tensor.

        Returns:
            `torch.Tensor`: A tensor of shape `(n_queries, n_passages)` containing the scores. The score
            tensor is saved on the "cpu" device.
