This controls the downsampling factor applied to image patches. The actual downsampling ratio is calculated as `1 / (pixel_shuffle_ratio^2)`. fake_image_token (`str`, *optional*, defaults to `"<|image|>"`): The placeholder token in the text that will be replaced with actual image tokens. This token serves as a marker indicating where images should be inserted in the text sequence. image_token (`str`, *optional*, defaults to `"<|image|>"`): The token to be used to represent an image in the text. start_of_image_token (`str`, *optional*, defaults to `"<|image_start|>"`): The special token that marks the beginning of an image sequence in the text. This token is prepended to image token sequences to delimit image boundaries. end_of_image_token (`str`, *optional*, defaults to `"<|image_end|>"`): The special token that marks the end of an image sequence in the text. This token is appended to image token sequences to delimit image boundaries. patch_token (`str`, *optional*, defaults to `"<|patch|>"`): The token used to represent individual image patches. Multiple patch tokens are used to represent the full image, with the number depending on the image size and patch configuration. tile_x_separator_token (`str`, *optional*, defaults to `"<|tile_x_separator|>"`): The token used to separate tiles (patches) horizontally within an image. This token is inserted between patches in the same row when images are split into multiple tiles. tile_y_separator_token (`str`, *optional*, defaults to `"<|tile_y_separator|>"`): The token used to separate tiles (patches) vertically within an image. This token is inserted between rows of patches when images are split into multiple tiles. ) chat_templateg?N)super__init__introunddownsample_ratiorfake_image_token image_tokenconvert_tokens_to_idsimage_token_idstart_of_img_tokenend_of_img_tokenimg_patch_token tile_tokentile_global_token)selfimage_processor tokenizerrr r(r)start_of_image_tokenend_of_image_token patch_tokentile_x_separator_tokentile_y_separator_tokenr!kwargs __class__rrr$%s+ zLlama4Processor.__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 rrrrrr)range)r1 aspect_rationum_patches_per_chunk img_stringratio_hratio_wyyxxrrr_prompt_split_image^s        z#Llama4Processor._prompt_split_imageimagestextr9returnc s|durtdjtfdjji|}t|ttfs|g}i}|dur҈j |}t |}jdd|i|d}|ddj dd\}}t |j |j j}|d } tfd d |D} | t|krztd | d t|dd} g} |D]E} | j}|dkr| | q| j}g}t|D]\}}||||kr| | |}| d7} ||q| d|q| t|krtd| }|ddd}j|fi|d}j||dgdti|||dS)aA Returns: [`BatchFeature`]: A [`BatchFeature`] with the following fields: - **input_ids** -- List of token ids to be fed to a model.
