# MinerU 


## Introduction

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

- [Magic-PDF](#Magic-PDF)  PDF Document Extraction  
- [Magic-Doc](#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

## Flowchart

![Flowchart](docs/images/flowchart_en.png)

### Dependency repositorys

- [PDF-Extract-Kit : A Comprehensive Toolkit for High-Quality PDF Content Extraction](https://github.com/opendatalab/PDF-Extract-Kit) 🚀🚀🚀

## 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:
```bash
conda create -n MinerU python=3.10
conda activate MinerU
```

### Installation and Configuration

#### 1. Install Magic-PDF

**1.Install dependencies**

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):

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

**2.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](#4-Acceleration-Using-CUDA-or-MPS).

```bash
pip install magic-pdf[full]==0.6.2b1
```
> ❗️❗️❗️
> We have pre-released the 0.6.2 beta version, addressing numerous issues mentioned in our logs. However, this build has not undergone full QA testing and does not represent the final release quality. Should you encounter any problems, please promptly report them to us via issues or revert to using version 0.6.1.
> ```bash
> pip install magic-pdf[full-cpu]==0.6.1
> ```



#### 2. Downloading model weights files

For detailed references, please see below [how_to_download_models](docs/how_to_download_models_en.md)

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](magic-pdf.template.json) file in the repository root directory.
```bash
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.

```json
{
  "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/
```bash
pip install --force-reinstall torch==2.3.1 torchvision==0.18.1 --index-url https://download.pytorch.org/whl/cu118
```
> ❗ ️Make sure to specify version
> ```bash
> torch==2.3.1 torchvision==0.18.1
> ```
>  in the command, as these are the highest versions we support. Failing to specify the versions may result in automatically installing higher versions which can cause the program to fail.

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


### Usage

#### 1.Usage via Command Line

###### simple

```bash
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:  
```bash
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.


###### more 

```bash
magic-pdf --help
```


#### 2. Usage via Api

###### Local
```python
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
```python
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")
```
