MinerU

Introduction

MinerU is a one-stop, open-source, high-quality data extraction tool, includes the following primary features:

• Magic-PDF PDF Document Extraction
  
• Magic-Doc Webpage & E-book Extraction

Magic-PDF

Introduction

Magic-PDF is a tool designed to convert PDF documents into Markdown format, capable of processing files stored locally or on object storage supporting S3 protocol.

Key features include:

• Support for multiple front-end model inputs
• Removal of headers, footers, footnotes, and page numbers
• Human-readable layout formatting
• Retains the original document's structure and formatting, including headings, paragraphs, lists, and more
• Extraction and display of images and tables within markdown
• Conversion of equations into LaTeX format
• Automatic detection and conversion of garbled PDFs
• Compatibility with CPU and GPU environments
• Available for Windows, Linux, and macOS platforms

Dependency repositorys

• PDF-Extract-Kit : A Comprehensive Toolkit for High-Quality PDF Content Extraction 🚀🚀🚀

Getting Started

Requirements

• Python >= 3.9

Using a virtual environment is recommended to avoid potential dependency conflicts; both venv and conda are suitable. For example:

conda create -n MinerU python=3.10
conda activate MinerU

Installation and Configuration

1. Install Magic-PDF

Install the full-feature package with pip:

Note: The pip-installed package supports CPU-only and is ideal for quick tests.

For CUDA/MPS acceleration in production, see Acceleration Using CUDA or MPS.

pip install magic-pdf[full-cpu]

The full-feature package depends on detectron2, which requires a compilation installation.
If you need to compile it yourself, please refer to https://github.com/facebookresearch/detectron2/issues/5114
Alternatively, you can directly use our precompiled whl package (limited to Python 3.10):

pip install detectron2 --extra-index-url https://myhloli.github.io/wheels/

2. Downloading model weights files

For detailed references, please see below how_to_download_models

After downloading the model weights, move the 'models' directory to a directory on a larger disk space, preferably an SSD.

3. Copy the Configuration File and Make Configurations

You can get the magic-pdf.template.json file in the repository root directory.

cp magic-pdf.template.json ~/magic-pdf.json

In magic-pdf.json, configure "models-dir" to point to the directory where the model weights files are located.

{
  "models-dir": "/tmp/models"
}

4. Acceleration Using CUDA or MPS

If you have an available Nvidia GPU or are using a Mac with Apple Silicon, you can leverage acceleration with CUDA or MPS respectively.

CUDA

You need to install the corresponding PyTorch version according to your CUDA version.
This example installs the CUDA 11.8 version.More information https://pytorch.org/get-started/locally/

pip install --force-reinstall torch==2.3.1 torchvision==0.18.1 --index-url https://download.pytorch.org/whl/cu118

Also, you need to modify the value of "device-mode" in the configuration file magic-pdf.json.

{
  "device-mode":"cuda"
}

MPS

For macOS users with M-series chip devices, you can use MPS for inference acceleration.
You also need to modify the value of "device-mode" in the configuration file magic-pdf.json.

{
  "device-mode":"mps"
}

Usage

1.Usage via Command Line

simple

magic-pdf pdf-command --pdf "pdf_path" --inside_model true

After the program has finished, you can find the generated markdown files under the directory "/tmp/magic-pdf".
You can find the corresponding xxx_model.json file in the markdown directory.
If you intend to do secondary development on the post-processing pipeline, you can use the command:

magic-pdf pdf-command --pdf "pdf_path" --model "model_json_path"

In this way, you won't need to re-run the model data, making debugging more convenient.

magic-pdf --help

2. Usage via Api

Local

image_writer = DiskReaderWriter(local_image_dir)
image_dir = str(os.path.basename(local_image_dir))
jso_useful_key = {"_pdf_type": "", "model_list": []}
pipe = UNIPipe(pdf_bytes, jso_useful_key, image_writer)
pipe.pipe_classify()
pipe.pipe_parse()
md_content = pipe.pipe_mk_markdown(image_dir, drop_mode="none")

Object Storage

s3pdf_cli = S3ReaderWriter(pdf_ak, pdf_sk, pdf_endpoint)
image_dir = "s3://img_bucket/"
s3image_cli = S3ReaderWriter(img_ak, img_sk, img_endpoint, parent_path=image_dir)
pdf_bytes = s3pdf_cli.read(s3_pdf_path, mode=s3pdf_cli.MODE_BIN)
jso_useful_key = {"_pdf_type": "", "model_list": []}
pipe = UNIPipe(pdf_bytes, jso_useful_key, s3image_cli)
pipe.pipe_classify()
pipe.pipe_parse()
md_content = pipe.pipe_mk_markdown(image_dir, drop_mode="none")

Demo can be referred to demo.py
