Install
Our environment is cuda11.8+torch2.6.0.
- Clone this repository and navigate to the DeepSeek-OCR-2 folder
git clone https://github.com/deepseek-ai/DeepSeek-OCR-2.git- Conda
conda create -n deepseek-ocr2 python=3.12.9 -y
conda activate deepseek-ocr2- Packages
- download the vllm-0.8.5 whl
pip install torch==2.6.0 torchvision==0.21.0 torchaudio==2.6.0 --index-url https://download.pytorch.org/whl/cu118
pip install vllm-0.8.5+cu118-cp38-abi3-manylinux1_x86_64.whl
pip install -r requirements.txt
pip install flash-attn==2.7.3 --no-build-isolationNote: if you want vLLM and transformers codes to run in the same environment, you don't need to worry about this installation error like: vllm 0.8.5+cu118 requires transformers>=4.51.1

- VLLM:
Note: change the INPUT_PATH/OUTPUT_PATH and other settings in the DeepSeek-OCR2-master/DeepSeek-OCR2-vllm/config.py
cd DeepSeek-OCR2-master/DeepSeek-OCR2-vllm- image: streaming output
python run_dpsk_ocr2_image.py- pdf: concurrency (on-par speed with DeepSeek-OCR)
python run_dpsk_ocr2_pdf.py- batch eval for benchmarks (i.e., OmniDocBench v1.5)

res = model.infer(tokenizer, prompt=prompt, image_file=image_file, output_path = output_path, base_size = 1024, image_size = 768, crop_mode=True, save_results = True)or you can

- Dynamic resolution
- Default: (0-6)×768×768 + 1×1024×1024 — (0-6)×144 + 256 visual tokens ✅

We would like to thank DeepSeek-OCR, Vary, GOT-OCR2.0, MinerU, PaddleOCR for their valuable models.
We also appreciate the benchmark OmniDocBench.
