## Install
0. Our environment is cuda11.8+torch2.0.1
1. Clone this repository and navigate to the GOT folder
```bash
git clone https://github.com/Ucas-HaoranWei/GOT-OCR2.0.git
cd 'the GOT folder'
```
2. Install Package
```Shell
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](https://drive.google.com/drive/folders/1OdDtsJ8bFJYlNUzCQG4hRkUL6V-qBQaN?usp=sharing)
- [BaiduYun](https://pan.baidu.com/s/1G4aArpCOt6I_trHv_1SE2g) code: OCR2
- Huggingface will be available soon.

## Demo
1. plain texts OCR:
```Shell
python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type ocr
```
2. format texts OCR:
```Shell
python3 GOT/demo/run_ocr_2.0.py  --model-name  /GOT_weights/  --image-file  /an/image/file.png  --type format
```
3. fine-grained OCR:
```Shell
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]
```
```Shell
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:
```Shell
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):
```Shell
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:
```Shell
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
0. Train sample can be found [here](https://github.com/Ucas-HaoranWei/GOT-OCR2.0/blob/main/assets/train_sample.jpg). Note that the '\<image>' in the 'conversations'-'human'-'value' is necessary!
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](https://github.com/Ucas-HaoranWei/Vary-tiny-600k).

```Shell
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/ \
 --use_im_start_end True   \
 --bf16 True   \
 --gradient_accumulation_steps 2    \
 --evaluation_strategy "no"   \
 --save_strategy "steps"  \
 --save_steps 200   \
 --save_total_limit 1   \
 --weight_decay 0.    \
 --warmup_ratio 0.001     \
 --lr_scheduler_type "cosine"    \
 --logging_steps 1    \
 --tf32 True     \
 --model_max_length 8192    \
 --gradient_checkpointing True   \
 --dataloader_num_workers 8    \
 --report_to none  \
 --per_device_train_batch_size 2    \
 --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](https://github.com/Ucas-HaoranWei/GOT-OCR2.0/tree/main/GOT-OCR-2.0-master/GOT/utils).
2. Change line 37 in [conversation_dataset_qwen.py](https://github.com/Ucas-HaoranWei/GOT-OCR2.0/tree/main/GOT-OCR-2.0-master/GOT/data) to your data_name.


## Eval
1. We use the [Fox](https://github.com/ucaslcl/Fox) and [OneChart](https://github.com/LingyvKong/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.
 ```Shell
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
```
