Software installation
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:
- torch == 1.11.0+cu113
- torchvision == 0.12.0+cu113

Getting Started
Data
This repository assumes the following structure of dataset:
> tree dataset_name
dataset_name
βββ test
β βββ metadata.jsonl
β βββ {image_path0}
β βββ {image_path1}
β .
β .
βββ train
β βββ metadata.jsonl
β βββ {image_path0}
β βββ {image_path1}
β .
β .
βββ validation
βββ metadata.jsonl
βββ {image_path0}
βββ {image_path1}
.
.
> cat dataset_name/test/metadata.jsonl
{"file_name": {image_path0}, "ground_truth": "{\"gt_parse\": {ground_truth_parse}, ... {other_metadata_not_used} ... }"}
{"file_name": {image_path1}, "ground_truth": "{\"gt_parse\": {ground_truth_parse}, ... {other_metadata_not_used} ... }"}
.
.
- The structure of
metadata.jsonl
file is in JSON Lines text format, i.e.,.jsonl
. Each line consists offile_name
: relative path to the image file.ground_truth
: string format (json dumped), the dictionary contains eithergt_parse
orgt_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, alldonut
model training share a same pipeline. For training and inference, the only thing to do is preparinggt_parse
orgt_parses
for the task in format described below.
For Document Classification
The gt_parse
follows the format of {"class" : {class_name}}
, for example, {"class" : "scientific_report"}
or {"class" : "presentation"}
.
For Document Information Extraction
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", ...}, ...], ...}
.
- More examples are available at CORD dataset.
- Google colab demo is available here.
- Gradio web demo is available here.
For Document Visual Question Answering
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"}]
.
- DocVQA Task1 has multiple answers, hence
gt_parses
should be a list of dictionary that contains a pair of question and answer. - Google colab demo is available here.
- Gradio web demo is available here.
For (Pseudo) Text Reading Task
The gt_parse
looks like {"text_sequence" : "word1 word2 word3 ... "}
- This task is also a pre-training task of Donut model.
- You can use our SynthDoG
πΆ to generate synthetic images for the text reading task with propergt_parse
. See./synthdog/README.md
for details.
Training
This is the configuration of Donut model training on CORD dataset used in our experiment. We ran this with a single NVIDIA A100 GPU.
python train.py --config config/train_cord.yaml \
--pretrained_model_name_or_path "naver-clova-ix/donut-base" \
--dataset_name_or_paths '["naver-clova-ix/cord-v2"]' \
--exp_version "test_experiment"
