Follow ups to DocumentQuestionAnswering Pipeline

[ankrgyl]

Feature request

PR #18414 has a number of TODOs left over which we'd like to track as follow up tasks.

Pipeline

• Add support for documents which have more than the tokenizer span (e.g. 512) words
• Add support for multi-page documents (e.g. for Donut, we need to present one image per page)
• Rework use of tokenizer to avoid the need for add_prefix_space=True
• Re-add support for Donut
• Refactor Donut usage in the pipeline or move logic into the tokenizer, so that pipeline does not have as much Donut-specific code

Testing

• Enable test_small_model_pt_donut once hf-internal-testing/tiny-random-donut is implemented

Documentation / Website

• Add DocumentQuestionAnswering demo to Hosted Inference API so that model demos work
• Add tutorial documentation to Task Summary

Motivation

These are follow ups that we cut from the initial scope of PR #18414.

Your contribution

Happy to contribute many or all of these.

cc'ing @Narsil for enabling the model on the inference API, cc'ing @stevhliu for adding tutorial documentation to the task summary

@NielsRogge because we removed donut-swin from AutoModelForDocumentQuestionAnswering, you can no longer create a pipeline with donut, i.e.

In [2]: p = pipeline('document-question-answering', model='naver-clova-ix/donut-base-finetuned-docvqa')
/Users/ankur/projects/transformers/venv/lib/python3.10/site-packages/torch/functional.py:478: UserWarning: torch.meshgrid: in an upcoming release, it will be required to pass the indexing argument. (Triggered internally at  /Users/runner/work/pytorch/pytorch/pytorch/aten/src/ATen/native/TensorShape.cpp:2895.)
  return _VF.meshgrid(tensors, **kwargs)  # type: ignore[attr-defined]
The model 'VisionEncoderDecoderModel' is not supported for document-question-answering. Supported models are ['LayoutLMForQuestionAnswering', 'LayoutLMv2ForQuestionAnswering', 'LayoutLMv3ForQuestionAnswering'].

Should we add it back to that list? Or what is the best way to support that?

[ankrgyl]

Could we re-open this (I don't think I have permissions to)? There are still a few changes necessary to complete all of the checkboxes.

@ankrgyl Can I ask you if I can work on this?
If I want to work on adding support for multi-page documents (e.g. for Donut, we need to present one image per page), may I ask you where I can start to proceed making contributions?

[ankrgyl]

Absolutely!

Feel free to start looking here: https://github.com/huggingface/transformers/blob/main/src/transformers/pipelines/document_question_answering.py

• Add support for multi-page documents (e.g. for Donut, we need to present one image per page)

Thank you! I carefully read it! In order to add support for multi-page documents in document_question_answering.py, should I modify some methods in that file such as preprocess()? Can I create a pull request of the file you provided after modifying those methods?

[elabongaatuo]

@ankrgyl Hello. I would love to contribute to this task : Add tutorial documentation to Task Summary. Is it open and may I get pointers on how to begin working on it?
Thank you.

[y3sar]

@elabongaatuo It seems like the Add tutorial documentation to Task Summary is still open. are you working on it? It seems you need to change starting from here

[elabongaatuo]

Hello @y3sar , no, I am not working on it at the moment.

[y3sar]

@elabongaatuo then I would like to take it up if there is no problem with you

Hello @y3sar , no, I am not working on it at the moment.

@y3sar , sure thing. 😊 no problem.

[rajveer43]

@ankrgyl I would Like to work on this Add tutorial documentation to Task Summary and also in Add support for multi-page documents (e.g. for Donut, we need to present one image per page)

[hackpk]

@ankrgyl Can i work on Refactor Donut usage ???

[dhivyeshrk]

Hey @ankrgyl ! I would be happy to contribute to this issue by adding support for multi-page documents.
Could you assign this to me ?

[ArthurZucker]

Hey! For anyone wanting to contribute, the best way is to just open a PR and link it here! We don't usually assign issues as they can be taken over in case of inactivity for example! 🤗
