Model Source Configuration

MinerU automatically downloads required models from HuggingFace on first run. If HuggingFace is inaccessible, you can switch model sources:

Switch to ModelScope Source

mineru -p <input_path> -o <output_path> --source modelscope

Or set environment variable:

export MINERU_MODEL_SOURCE=modelscope
mineru -p <input_path> -o <output_path>

Using Local Models

1. Download Models Locally

mineru-models-download --help

Or use interactive command-line tool to select models:

mineru-models-download

After download, model paths will be displayed in current terminal and automatically written to mineru.json in user directory.

2. Parse Using Local Models

mineru -p <input_path> -o <output_path> --source local

Or enable via environment variable:

export MINERU_MODEL_SOURCE=local
mineru -p <input_path> -o <output_path>

Using sglang to Accelerate VLM Model Inference

Through the sglang-engine Mode

mineru -p <input_path> -o <output_path> -b vlm-sglang-engine

Through the sglang-server/client Mode

Start Server:
```
mineru-sglang-server --port 30000
```

Use Client in another terminal:

mineru -p <input_path> -o <output_path> -b vlm-sglang-client -u http://127.0.0.1:30000
