See the [`~Llama4Processor.__call__`] and [`~Llama4Processor.decode`] for more information. Args: image_processor ([`AutoImageProcessor`], *optional*): The image processor is a required input. tokenizer ([`PreTrainedTokenizer`, `PreTrainedTokenizerFast`], *optional*): The tokenizer is a required input. patch_size (`int`, *optional*, defaults to 28): The size of image patches for tokenization. img_size (`int`, *optional*, defaults to 364): The size of the image to be tokenized. This should correspond to the size given to the image processor. image_token (`str`, *optional*, defaults to `"<|image|>"`): The token to be used to represent an image in the text. downsample_factor (`int`, *optional*, defaults to 1): The factor by which to scale the patch size. start_of_img_token (`str`, *optional*, defaults to `"<|START_OF_IMG|>"`): The token to be used to represent the start of an image in the text. end_of_img_token (`str`, *optional*, defaults to `"<|END_OF_IMG|>"`): The token to be used to represent the end of an image in the text. img_patch_token (`str`, *optional*, defaults to `"<|IMG_PATCH|>"`): The token to be used to represent an image patch in the text. img_line_break_token (`str`, *optional*, defaults to `"<|IMG_LINE_BREAK|>"`): The token to be used to represent a line break in the text. tile_token (`str`, *optional*, defaults to `"TILE"`): The token to be used to represent an image patch in the text. tile_global_token (`str`, *optional*, defaults to `"TILE_GLOBAL"`): The token to be used to represent the cover image in the text. chat_template (`str`, *optional*): A Jinja template which will be used to convert lists of messages in a chat into a tokenizable string. image_processor tokenizerZAutoImageProcessorZ AutoTokenizerNg? <|image|><|image_start|> <|image_end|> <|patch|><|tile_x_separator|><|tile_y_separator|>) patch_sizepixel_shuffle_ratioc  sjtj||| dttd|d|_||_||_||_||j|_ ||_ ||_ | |_ | |_ | |_dS)N) chat_templateg?)super__init__rrounddownsample_ratior'fake_image_token image_tokenZconvert_tokens_to_idsZimage_token_idZstart_of_img_tokenZend_of_img_tokenZimg_patch_tokenZ tile_tokenZtile_global_token)selfrrr'r(r/r0Zstart_of_image_tokenZend_of_image_tokenZ patch_tokenZtile_x_separator_tokenZtile_y_separator_tokenr)kwargs __class__rrr,QszLlama4Processor.__init__cCs|d}|\}}||dkr\t|D]:}t|D]$}|d|7}||dkr,|d7}q,|d7}q |d7}|d|7}|d7}|S)z Create a structured string representation of image tokens Args: num_patches: Number of patches in the image Returns: String with appropriate image tokens r"r$r%r&r!r#)range)r1Z aspect_rationum_patches_per_chunkZ img_stringZratio_hZratio_wyyxxrrr_prompt_split_imageos         z#Llama4Processor._prompt_split_image)imagestextr2returnc s|durtdjtfdjji|}t|ttfs>|g}i}|durj |}t |}jfd|i|d}|ddj dd\}} t |j | j j} |d } tfd d |D} | t|krtd | d t|dd} g}|D]}|j}|dkr*||q|j}g}t|D]@\}}||||krB| | | }| d7} ||qB|d|q| t|krtd|}|ddd}j|fi|d}j||dgdti|||dS)au Main method to prepare for the model one or several sequences(s) and image(s). This method forwards the `text` and `kwargs` arguments to PreTrainedTokenizerFast's [`~PreTrainedTokenizerFast.__call__`] to encode the text. To prepare the vision inputs, this method forwards the `images` and `kwargs` arguments to Llama4ImageProcessor's [`~Llama4ImageProcessor.__call__`] if `images` is not `None`. 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. Both channels-first and channels-last formats are supported. 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. Returned when `text` is not `None`. - **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`.
