Towards OCR-2.0 via a Unified End-to-end Model

---

Install

0. Our environment is cuda11.8+torch2.0.1
1. Clone this repository and navigate to the GOT folder

git clone https://github.com/Ucas-HaoranWei/GOT-OCR2.0.git
cd 'the GOT folder'

2. Install Package

conda create -n got python=3.10 -y
conda activate got
pip install -e .

3. Install Flash-Attention

pip install ninja
pip install flash-attn --no-build-isolation

GOT Weights

• Google Drive
• BaiduYun code: OCR2

Demo

1. plain texts OCR:

python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type ocr

2. format texts OCR:

python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type format

3. fine-grained OCR:

python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type format/ocr --box [x1,y1,x2,y2]

python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type format/ocr --color red/green/blue

4. multi-crop OCR:

python3 GOT/demo/run_ocr_2.0_crop.py  --model-name  /GOT_weights/ --image-file  /an/image/file.png 

5. multi-page OCR (the image path contains multiple .png files):

python3 GOT/demo/run_ocr_2.0_crop.py  --model-name  /GOT_weights/ --image-file  /images/path/  --multi-page

6. render the formatted OCR results:

python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type format --render

Note: The rendering results can be found in /results/demo.html. Please open the demo.html to see the results.

Train

1. This codebase only supports post-training (stage-2/stage-3) upon our GOT weights.
2. If you want train from stage-1 described in our paper, you need this repo.

deepspeed   /GOT-OCR-2.0-master/GOT/train/train_GOT.py \
 --deepspeed /GOT-OCR-2.0-master/zero_config/zero2.json    --model_name_or_path /GOT_weights/ \

 --num_train_epochs 1  \
 --learning_rate 2e-5   \
 --datasets pdf-ocr+scence \
 --output_dir /your/output.path

Note:

1. Change the corresponding data information in constant.py.
2. Change line 37 in conversation_dataset_qwen.py to your data_name.

Eval

1. We use the Fox and OneChart benchmarks, and other benchmarks can be found in the weights download link.
2. The eval codes can be found in GOT/eval.
3. You can use the evaluate_GOT.py to run the eval. If you have 8 GPUs， the --num-chunks can be set to 8.

python3 GOT/eval/evaluate_GOT.py --model-name /GOT_weights/ --gtfile_path xxxx.json --image_path  /image/path/ --out_path /data/eval_results/GOT_mathpix_test/ --num-chunks 8 --datatype OCR
