[`IdeficsProcessor`] offers all the functionalities of [`Idefics2ImageProcessor`] and [`LlamaTokenizerFast`]. See the docstring of [`~IdeficsProcessor.__call__`] and [`~IdeficsProcessor.decode`] for more information. Args: image_processor (`Idefics2ImageProcessor`): An instance of [`Idefics2ImageProcessor`]. The image processor is a required input. tokenizer (`PreTrainedTokenizerBase`, *optional*): An instance of [`PreTrainedTokenizerBase`]. This should correspond with the model's text model. The tokenizer is a required input. image_seq_len (`int`, *optional*, defaults to 64): The length of the image sequence i.e. the number of tokens per image in the input. This parameter is used to build the string from the input prompt and image tokens and should match the config.perceiver_config.resampler_n_latents value for the model used. 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 tokenizerIdefics2ImageProcessor AutoTokenizerN@r chat_templatec st|ds,tddddj|_tddddj|_d|j|jgi}||||j|_n |j|_|j|_|j|_tdddd|_ |d|j gi||_ t j |||d dS) N image_tokenzFT) normalizedspecialzadditional_special_tokensz)r4) hasattrrcontentfake_image_tokenr5r)convert_tokens_to_idsimage_token_idimage_boundary_tokenend_of_utterance_tokenr super__init__)selfr/r0r r4kwargs tokens_to_add __class__rrrAZs  zIdefics2Processor.__init__cCsTg}|D]#}g}|D]}t|r||q t|r!|t|q ||q|Sr)r appendrr )rBprompts prompt_imagespromptimagesrrrr_extract_images_from_promptsns  z.Idefics2Processor._extract_images_from_promptsrKtextrrCrc s|dur dur td|jtfd|jji|}|ddd}|dur'|n|j}|ddd}g} i} |durt|trC|g}nt|t sSt|dtsStd |j } |j } | | || } |j j ro| d } |d 9}g}|D] }| || || | }|| | | }||qs|j|fi|d}|j||d gd | |durZtrggnltt tfrtdr|durt| tkrtd | dt| d| dtd dgt t| fddtt| Dn#gntt tfs'tdt tfs'tdds'tdddD}|durC|| ksCtd| d|dddD|j fi|d}| |t| |dS)a Processes the input prompts and returns a BatchEncoding. Example: ```python >>> import requests >>> from transformers import Idefics2Processor >>> from transformers.image_utils import load_image >>> processor = Idefics2Processor.from_pretrained("HuggingFaceM4/idefics2-8b", image_seq_len=2) >>> processor.image_processor.do_image_splitting = False # Force as False to simplify the example >>> url1 = "https://cdn.britannica.com/61/93061-050-99147DCE/Statue-of-Liberty-Island-New-York-Bay.jpg" >>> url2 = "https://cdn.britannica.com/59/94459-050-DBA42467/Skyline-Chicago.jpg" >>> image1, image2 = load_image(url1), load_image(url2) >>> images = [[image1], [image2]] >>> text = [ ... "In this image, we see", ... "bla bla bla", ... ] >>> outputs = processor(images=images, text=text, return_tensors="pt", padding=True) >>> input_ids = outputs.input_ids >>> input_tokens = processor.tokenizer.batch_decode(input_ids) >>> print(input_tokens) [' In this image, we see', ' bla bla bla'] ``` Args: images (`PIL.Image.Image`, `np.ndarray`, `torch.Tensor`, `list[PIL.Image.Image]`, `list[np.ndarray]`, `list[torch.Tensor]`, *optional*): The image or batch of images to be prepared. Each image can be a PIL image, NumPy array or PyTorch tensor. If is of type `list[ImageInput]`, it's assumed that this is for a single prompt i.e. of batch size 1. text (`Union[TextInput, PreTokenizedInput, list[TextInput], list[PreTokenizedInput]]`, *optional*): 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). Wherever an image token, `` is encountered it is expanded to `` + `` * `image_seq_len` * `. return_tensors (`Union[str, TensorType]`, *optional*): If set, will return tensors of a particular framework. See [`PreTrainedTokenizerFast.__call__`] for more information. Nz+You must provide either `text` or `images`.tokenizer_init_kwargsr(r r,return_tensorsrzAInvalid input text.
