Release

• [2024/9/03] 🔥🔥🔥 We release a very strong and comprehensive OCR model GOT-OCR2.0.
• [2024/7/16] 🎉🎉🎉 OneChart is accepted by ACM'MM 2024 oral (3.97%)!
• [2024/7/2] 🔥🔥🔥 Vary is accepted by ECCV2024. To thank everyone for their attention, I will release a model that performs on par with the Vary-document soon.
• [2024/5/27] 🔥🔥🔥 We present a document understanding benchmark in Fox .
• [2024/5/24] 🔥🔥🔥 We propose a multi-page document understanding work -- Fox, which supports 8-page pdf-image input !!!
• [2024/4/21] 🔥🔥🔥 For OneChart, we have released the web demo in Project Page. Have fun!!
• [2024/4/21] 🔥🔥🔥 We present a Vary-tiny LAVIS codebase (for training from scratch) and the Vary-600k dataset (300K English and 300K Chinese pages) here !!!
• [2024/4/15]🔥🔥🔥We release a chart parsing model OneChart here.
• [2024/4/12]🔥🔥🔥We will release a chart parsing model based on Vary-tiny next week. The model supports both English and Chinese charts.
• [2024/3/16]🔥🔥🔥I found many friends very interested in Vary-tiny(OPT-125M), so I opened source it here, a PDF-dense OCR and object detection version.
• [2023/1/23]🔥🔥🔥We release the Vary-toy here. Besides, we show the super good Vary-family results here.
• [2023/12/29]🔥🔥🔥We will release a new model (a small-size Vary, about 2B) at the beginning of next month and introduce a new feature (object detection). Our online demo will be temporarily closed to prepare for the deployment of the new model.
• [2023/12/11] We released the online demo, have fun!
• [2023/12/11] We released the codes of Vary (train and inference)!

Install

1. Clone this repository and navigate to the Vary folder

git clone https://github.com/Ucas-HaoranWei/Vary.git
cd Vary

2. Install Package

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

3. Install Flash-Attention

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

Vary Weights

• If you are in urgent need of weights for your research recently, please contact me by email.
• Download the CLIP-VIT-L in Hugging Face

Demo

1. Update the CLIP-VIT path in the codes (/cache/vit-large-patch14/) to your path.

python vary/demo/run_qwen_vary.py  --model-name  /vary/model/path/ --image-file /an/image/file.png

Train

• We currently do not plan to open source the weights of the intermediate.
• However, we release the train codes. So you can train on your own dataset. If you want to do this, you can try this:

1. For Vary-base (one machine, if you have multiple machines you need to prepare your host file)

deepspeed   Vary/train/train_qwen_vary.py  --deepspeed /Vary/zero_config/zero2.json
            --model_name_or_path /Qwen-7B/path/
            --vision_tower /vit-large-patch14/path/
            --freeze_vision_tower True
            --freeze_lm_model False
            --vision_select_layer  -2
            --use_im_start_end True
            --bf16 True
            --per_device_eval_batch_size 4
            --gradient_accumulation_steps 1
            --evaluation_strategy "no"
            --save_strategy "steps"
            --save_steps 5000
            --save_total_limit 1
            --weight_decay 0.
            --warmup_ratio 0.03
            --lr_scheduler_type "cosine"
            --logging_steps 1 --tf32 True
            --model_max_length 4096
            --gradient_checkpointing True
            --dataloader_num_workers 4
            --report_to none
            --per_device_train_batch_size 4
            --num_train_epochs 1
            --learning_rate 5e-5
            --datasets  data_name1+data_name2+data_name3
            --output_dir /path/to/output/

2. For Vary-tiny

deepspeed   Vary/train/train_opt.py  --deepspeed /Vary/zero_config/zero2.json
            --model_name_or_path /opt125m/path/
            --conversation_version opt
            --freeze_vision_tower False
            --freeze_lm_model False
            --use_im_start_end True
            --bf16 True
            --per_device_eval_batch_size 4
            --gradient_accumulation_steps 1
            --evaluation_strategy "no"
            --save_strategy "steps"
            --save_steps 5000
            --save_total_limit 1
            --weight_decay 0.
            --warmup_ratio 0.03
            --lr_scheduler_type "cosine"
            --logging_steps 1 --tf32 True
            --model_max_length 4096
            --gradient_checkpointing True
            --dataloader_num_workers 4
            --report_to none
            --per_device_train_batch_size 16
            --num_train_epochs 1
            --learning_rate 5e-5
            --datasets  data_name1+data_name2+data_name3
            --output_dir /path/to/output/
