[`LayoutLMv2Processor`] offers all the functionalities you need to prepare data for the model. It first uses [`LayoutLMv2ImageProcessor`] to resize document images to a fixed size, and optionally applies OCR to get words and normalized bounding boxes. These are then provided to [`LayoutLMv2Tokenizer`] or [`LayoutLMv2TokenizerFast`], which turns the words and bounding boxes into token-level `input_ids`, `attention_mask`, `token_type_ids`, `bbox`. Optionally, one can provide integer `word_labels`, which are turned into token-level `labels` for token classification tasks (such as FUNSD, CORD). Args: image_processor (`LayoutLMv2ImageProcessor`, *optional*): An instance of [`LayoutLMv2ImageProcessor`]. The image processor is a required input. tokenizer (`LayoutLMv2Tokenizer` or `LayoutLMv2TokenizerFast`, *optional*): An instance of [`LayoutLMv2Tokenizer`] or [`LayoutLMv2TokenizerFast`]. The tokenizer is a required input. image_processor tokenizerLayoutLMv2ImageProcessor)LayoutLMv2TokenizerLayoutLMv2TokenizerFastc d}d|vr+tjdt|jd}||n|}| t d| t dt |||y)Nfeature_extractorzhThe `feature_extractor` argument is deprecated and will be removed in v5, use `image_processor` instead.z)You need to specify an `image_processor`.z"You need to specify a `tokenizer`.)warningswarn FutureWarningpop ValueErrorsuper__init__)selfrrkwargsr __class__s g/var/www/html/venv/lib/python3.12/site-packages/transformers/models/layoutlmv2/processing_layoutlmv2.pyrzLayoutLMv2Processor.__init__3sw  & ( MM  !' +> ? -<-H/N_  "HI I  AB B )4text text_pairboxes word_labelsadd_special_tokenspadding truncation max_lengthstridepad_to_multiple_ofreturn_token_type_idsreturn_attention_maskreturn_overflowing_tokensreturn_special_tokens_maskreturn_offsets_mapping return_lengthverbosereturn_tensorsreturnc T|jjr | td|jjr | td|dur|dur td|j||}|0|jjr|t|tr|g}|d}|j did ||n|dd ||ndd ||n|d d |d |d|d|d| d| d| d| d| d|d|d|d|d|d||}|j d}|dur|j||d}||d<|S)a This method first forwards the `images` argument to [`~LayoutLMv2ImageProcessor.__call__`]. In case [`LayoutLMv2ImageProcessor`] was initialized with `apply_ocr` set to `True`, it passes the obtained words and bounding boxes along with the additional arguments to [`~LayoutLMv2Tokenizer.__call__`] and returns the output, together with resized `images`. In case [`LayoutLMv2ImageProcessor`] was initialized with `apply_ocr` set to `False`, it passes the words (`text`/``text_pair`) and `boxes` specified by the user along with the additional arguments to [`~LayoutLMv2Tokenizer.__call__`] and returns the output, together with resized `images``. Please refer to the docstring of the above two methods for more information.
