[`LayoutLMv3Processor`] offers all the functionalities you need to prepare data for the model. It first uses [`LayoutLMv3ImageProcessor`] to resize and normalize document images, and optionally applies OCR to get words and normalized bounding boxes. These are then provided to [`LayoutLMv3Tokenizer`] or [`LayoutLMv3TokenizerFast`], 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 (`LayoutLMv3ImageProcessor`, *optional*): An instance of [`LayoutLMv3ImageProcessor`]. The image processor is a required input. tokenizer (`LayoutLMv3Tokenizer` or `LayoutLMv3TokenizerFast`, *optional*): An instance of [`LayoutLMv3Tokenizer`] or [`LayoutLMv3TokenizerFast`]. The tokenizer is a required input. image_processor tokenizerLayoutLMv3ImageProcessor)LayoutLMv3TokenizerLayoutLMv3TokenizerFastNc sdd}d|vrtdt|d}|dur|n|}|dur!td|dur)tdt||dS)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__j/var/www/html/ai/venv/lib/python3.10/site-packages/transformers/models/layoutlmv3/processing_layoutlmv3.pyr3s zLayoutLMv3Processor.__init__TFrtext 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_tensorsreturncKsD|jjr |dur td|jjr|durtd|j||d}|dur7|jjr7|dur7t|tr3|g}|d}|jdid|durB|n|dd|durM|ndd|durV|n|dd |d |d |d |d | d| d| d| d| d|d|d|d|d|d||}|d}|dur|||d}||d<|S)aF This method first forwards the `images` argument to [`~LayoutLMv3ImageProcessor.__call__`].
