# MinerU
## 项目简介
MinerU是一款将PDF转化为机器可读格式的工具（如markdown、json），可以很方便地抽取为任意格式。
MinerU诞生于[书生-浦语](https://github.com/InternLM/InternLM)的预训练过程中，我们将会集中精力解决科技文献中的符号转化问题，以此在大模型时代推动人类科技的发展。

## 主要功能

- 删除页眉、页脚、脚注、页码等元素，保持语义连贯
- 符合人类阅读顺序的排版格式
- 保留原文档的结构和格式，包括标题、段落、列表等
- 提取图像、图片标题、表格、表格标题
- 自动识别文档中的公式并将公式转换成latex
- 乱码PDF自动检测并启用OCR
- 支持CPU和GPU环境
- 支持windows/linux/mac平台


## 快速开始

如果遇到任何问题，请先查询<a href="#faq">FAQ</a>
如果遇到效果不及预期，查询<a href="#known-issue">Known Issue</a>
有3种不同方式可以体验MinerU的效果：
- 在线体验
- 使用CPU快速体验（Windows，Linux，Mac）
- Linux/Windows + GPU

### 在线体验

[在线体验点击这里](TODO)

### 使用CPU快速体验

```bash
 command to install magic-pdf[full]
```


### 使用GPU
- [ubuntu22.04 + GPU]()
- [windows10/11 + GPU]()


## 使用

### 命令行

TODO

### API

处理本地磁盘上的文件
```python
image_writer = DiskReaderWriter(local_image_dir)
image_dir = str(os.path.basename(local_image_dir))
jso_useful_key = {"_pdf_type": "", "model_list": model_json}
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")
```

处理对象存储上的文件
```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": model_json}
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")
```

详细实现可参考 
- [demo.py 最简单的处理方式](demo/demo.py)
- [magic_pdf_parse_main.py 能够更清晰看到处理流程](demo/magic_pdf_parse_main.py)


### 二次开发

TODO

# TODO

- [ ] 基于语义的阅读顺序
- [ ] 正文中列表识别
- [ ] 正文中代码块识别
- [ ] 目录识别
- [ ] 表格识别
- [ ] 化学式识别
- [ ] 几何图形识别


# Known Issue
- 阅读顺序基于规则的分割，在一些情况下会乱序
- 列表、代码块、目录在layout模型里还没有支持
- 漫画书、艺术图册、小学教材、习题尚不能很好解析

好消息是，这些我们正在努力实现！

# License Information

[LICENSE.md](LICENSE.md)

The project currently leverages PyMuPDF to deliver advanced functionalities; however, its adherence to the AGPL license may impose limitations on certain use cases. In upcoming iterations, we intend to explore and transition to a more permissively licensed PDF processing library to enhance user-friendliness and flexibility.
