build_string_from_input(
    prompt="Prefix str"
    bos_token="<s>",
    image_seq_len=3,
    image_token="<im>",
)

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.
