This method forwards the `text` and `kwargs` arguments to GemmaTokenizerFast's [`~GemmaTokenizerFast.__call__`] if `text` is not `None` to encode the text. To prepare the image(s), this method forwards the `images` and `kwrags` arguments to SiglipImageProcessor's [`~SiglipImageProcessor.__call__`] if `images` is not `None`. Please refer to the docstring of the above two methods for more information. The usage for PaliGemma fine-tuning preparation is slightly different than usual. suffix passed are suffixes to the prompt in `text`, and will be placed after the prompt. This is because attention is handled differently for the prefix and the suffix. For instance, ```python image = PIL_cow_image prompt = "answer en Where is the cow standing?" suffix = "on the beach" inputs = processor(text=prompt, images=image, suffix=suffix) ``` Here `inputs` will contain the `input_ids` and `token_type_ids` that follow ```python inputs["input_ids"][:, 256:] # tensor([[ 2, 6006, 603, 573, 13910, 9980, 235336, 108, 477, 573, 8318]]) inputs["token_type_ids"][:, 256:] tensor([[0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1]]) ``` Meaning the last three tokens are of "label" ("suffix") type while the other ones are of "prefix" type. 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. suffix (`str`, `List[str]`, `List[List[str]]`): The suffixes or batch of suffixes to be encoded. Only necessary for finetuning. See https://github.com/google-research/big_vision/blob/main/big_vision/configs/proj/paligemma/README.md for more information. If your prompt is " What is on the image", the suffix corresponds to the expected prediction "a cow sitting on a bench". Returns: [`BatchFeature`]: A [`BatchFeature`] with the following fields: - **input_ids** -- List of token ids to be fed to a model. Returned when `text` is not `None`. If `suffix` is provided, the `input_ids` will also contain the suffix input ids. - **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`. - **labels** -- Labels compatible with training if `suffix` is not None tokenizer_init_kwargsr'rNTFzF`images` are expected as arguments to a `PaliGemmaProcessor` instance.z]You are using PaliGemma without a text prefix.
