Official Implementation of Donut and SynthDoG | Paper | Slide | Poster
Donut 🍩, Document understanding transformer, is a new method of document understanding that utilizes an OCR-free end-to-end Transformer model. Donut does not require off-the-shelf OCR engines/APIs, yet it shows state-of-the-art performances on various visual document understanding tasks, such as visual document classification or information extraction (a.k.a. document parsing). In addition, we present SynthDoG 🐶, Synthetic Document Generator, that helps the model pre-training to be flexible on various languages and domains.
Our academic paper, which describes our method in detail and provides full experimental results and analyses, can be found here:
OCR-free Document Understanding Transformer.

2022-11-14 New version 1.0.9 is released (pip install donut-python --upgrade). See 1.0.9 Release Notes.
2022-08-12 Donut 🍩 is also available at huggingface/transformers 🤗 (contributed by @NielsRogge). donut-python loads the pre-trained weights from the official branch of the model repositories. See 1.0.5 Release Notes.
2022-08-05 A well-executed hands-on tutorial on donut 🍩 is published at Towards Data Science (written by @estaudere).
2022-07-20 First Commit, We release our code, model weights, synthetic data and generator.
pip install donut-python
or clone this repository and install the dependencies:
git clone https://github.com/clovaai/donut.git
cd donut/
conda create -n donut_official python=3.7
conda activate donut_official
pip install .
We tested donut with:

{"file_name": {image_path1}, "ground_truth": "{\"gt_parse\": {ground_truth_parse}, ... {other_metadata_not_used} ... }"}
.
.
metadata.jsonl file is in JSON Lines text format, i.e., .jsonl. Each line consists of
file_name : relative path to the image file.ground_truth : string format (json dumped), the dictionary contains either gt_parse or gt_parses. Other fields (metadata) can be added to the dictionary but will not be used.donut interprets all tasks as a JSON prediction problem. As a result, all donut model training share a same pipeline. For training and inference, the only thing to do is preparing gt_parse or gt_parses for the task in format described below.The gt_parse follows the format of {"class" : {class_name}}, for example, {"class" : "scientific_report"} or {"class" : "presentation"}.
The gt_parse is a JSON object that contains full information of the document image, for example, the JSON object for a receipt may look like {"menu" : [{"nm": "ICE BLACKCOFFEE", "cnt": "2", ...}, ...], ...}.
The gt_parses follows the format of [{"question" : {question_sentence}, "answer" : {answer_candidate_1}}, {"question" : {question_sentence}, "answer" : {answer_candidate_2}}, ...], for example, [{"question" : "what is the model name?", "answer" : "donut"}, {"question" : "what is the model name?", "answer" : "document understanding transformer"}].
gt_parses should be a list of dictionary that contains a pair of question and answer.The gt_parse looks like {"text_sequence" : "word1 word2 word3 ... "}
gt_parse. See ./synthdog/README.md for details.This is the configuration of Donut model training on CORD dataset used in our experiment. We ran this with a single NVIDIA A100 GPU.
