Install

Our environment is cuda11.8+torch2.6.0.

  1. Clone this repository and navigate to the DeepSeek-OCR-2 folder
    git clone https://github.com/deepseek-ai/DeepSeek-OCR-2.git
  2. Conda
    conda create -n deepseek-ocr2 python=3.12.9 -y
    conda activate deepseek-ocr2
  3. 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-isolation

    Note: 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-Inference

  • 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
  1. image: streaming output
    python run_dpsk_ocr2_image.py
  2. pdf: concurrency (on-par speed with DeepSeek-OCR)
    python run_dpsk_ocr2_pdf.py
  3. batch eval for benchmarks (i.e., OmniDocBench v1.5)
    python run_dpsk_ocr2_eval_batch.py

Transformers-Inference

  • Transformers
    
    from transformers import AutoModel, AutoTokenizer
    import torch
    import os
    os.environ["CUDA_VISIBLE_DEVICES"] = '0'
    model_name = 'deepseek-ai/DeepSeek-OCR-2'

tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModel.from_pretrained(model_name, _attn_implementation='flash_attention_2', trust_remote_code=True, use_safetensors=True)
model = model.eval().cuda().to(torch.bfloat16)

prompt = "<image>\nFree OCR. "

prompt = "<image>\n<|grounding|>Convert the document to markdown. "
image_file = 'your_image.jpg'
output_path = 'your/output/dir'

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
```Shell
cd DeepSeek-OCR2-master/DeepSeek-OCR2-hf
python run_dpsk_ocr2.py

Support-Modes

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

Main Prompts

# document: <image>\n<|grounding|>Convert the document to markdown.
# without layouts: <image>\nFree OCR.

Acknowledgement

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

We also appreciate the benchmark OmniDocBench.
