# 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，希望在大模型时代为科技发展做出贡献。
相比国内外知名商用产品MinerU还很年轻，如果遇到问题或者结果不及预期请到[issue](https://github.com/opendatalab/MinerU/issues)提交问题，同时**附上相关PDF**。

https://github.com/user-attachments/assets/4bea02c9-6d54-4cd6-97ed-dff14340982c

## 主要功能

- 删除页眉、页脚、脚注、页码等元素，保持语义连贯
- 对多栏输出符合人类阅读顺序的文本
- 保留原文档的结构，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
- 自动识别文档中的表格并将表格转换成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

如果遇到任何安装问题，请先查询 <a href="#faq">FAQ</a> </br>
如果遇到解析效果不及预期，参考 <a href="#known-issues">Known Issues</a></br>
有3种不同方式可以体验MinerU的效果：

- [在线体验(无需任何安装)](#在线体验)
- [使用CPU快速体验（Windows，Linux，Mac）](#使用cpu快速体验)
- [Linux/Windows + CUDA](#使用gpu)

**⚠️安装前必看——软硬件环境支持说明**

为了确保项目的稳定性和可靠性，我们在开发过程中仅对特定的软硬件环境进行优化和测试。这样当用户在推荐的系统配置上部署和运行项目时，能够获得最佳的性能表现和最少的兼容性问题。

通过集中资源和精力于主线环境，我们团队能够更高效地解决潜在的BUG，及时开发新功能。

在非主线环境中，由于硬件、软件配置的多样性，以及第三方依赖项的兼容性问题，我们无法100%保证项目的完全可用性。因此，对于希望在非推荐环境中使用本项目的用户，我们建议先仔细阅读文档以及FAQ，大多数问题已经在FAQ中有对应的解决方案，除此之外我们鼓励社区反馈问题，以便我们能够逐步扩大支持范围。

### 使用CPU快速体验

#### 1. 安装magic-pdf

最新版本国内镜像源同步可能会有延迟，请耐心等待

```bash
conda create -n MinerU python=3.10
conda activate MinerU
pip install -U magic-pdf[full] --extra-index-url https://wheels.myhloli.com -i https://pypi.tuna.tsinghua.edu.cn/simple
```

#### 2. 下载模型权重文件

详细参考 [如何下载模型文件](docs/how_to_download_models_zh_cn.md)

#### 3. 修改配置文件以进行额外配置

完成[2. 下载模型权重文件](#2-下载模型权重文件)步骤后，脚本会自动生成用户目录下的magic-pdf.json文件，并自动配置默认模型路径。
您可在【用户目录】下找到magic-pdf.json文件。
> windows的用户目录为 "C:\\Users\\用户名", linux用户目录为 "/home/用户名", macOS用户目录为 "/Users/用户名"

您可修改该文件中的部分配置实现功能的开关，如表格识别功能：

>如json内没有如下项目，请手动添加需要的项目，并删除注释内容（标准json不支持注释）

```json
{
  // other config
  "table-config": {
        "model": "TableMaster", // 使用structEqTable请修改为'struct_eqtable'
        "is_table_recog_enable": false, // 表格识别功能默认是关闭的，如果需要修改此处的值
        "max_time": 400
    }
}
```

### 使用GPU

如果您的设备支持CUDA，且满足主线环境中的显卡要求，则可以使用GPU加速，请根据自己的系统选择适合的教程：

- [Ubuntu22.04LTS + GPU](docs/README_Ubuntu_CUDA_Acceleration_zh_CN.md)
- [Windows10/11 + GPU](docs/README_Windows_CUDA_Acceleration_zh_CN.md)
- 使用Docker快速部署
    > Docker 需设备gpu显存大于等于16GB，默认开启所有加速功能
    > 
    > 运行本docker前可以通过以下命令检测自己的设备是否支持在docker上使用CUDA加速
    > 
    > ```bash
    > docker run --rm --gpus=all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
    > ```
  ```bash
  wget https://github.com/opendatalab/MinerU/raw/master/Dockerfile
  docker build -t mineru:latest .
  docker run --rm -it --gpus=all mineru:latest /bin/bash
  magic-pdf --help
  ```

                               outperform ocr. auto: automatically choose the
                               best method for parsing pdf from ocr and txt.
                               without method specified, auto will be used by
                               default.
  -l, --lang TEXT              Input the languages in the pdf (if known) to
                               improve OCR accuracy.  Optional. You should

  --help                       Show this message and exit.


## show version
magic-pdf -v

## command line example
magic-pdf -p {some_pdf} -o {some_output_dir} -m auto
```

其中 `{some_pdf}` 可以是单个pdf文件，也可以是一个包含多个pdf文件的目录。
运行完命令后输出的结果会保存在`{some_output_dir}`目录下, 输出的文件列表如下

```text
├── some_pdf.md                          # markdown 文件
├── images                               # 存放图片目录
├── some_pdf_layout.pdf                  # layout 绘图
├── some_pdf_middle.json                 # minerU 中间处理结果
├── some_pdf_model.json                  # 模型推理结果
├── some_pdf_origin.pdf                  # 原 pdf 文件
├── some_pdf_spans.pdf                   # 最小粒度的bbox位置信息绘图
└── some_pdf_content_list.json           # 按阅读顺序排列的富文本json
```

更多有关输出文件的信息，请参考[输出文件说明](docs/output_file_zh_cn.md)

### 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": []}
pipe = UNIPipe(pdf_bytes, jso_useful_key, image_writer)
pipe.pipe_classify()
pipe.pipe_analyze()
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": []}
pipe = UNIPipe(pdf_bytes, jso_useful_key, s3image_cli)
pipe.pipe_classify()
pipe.pipe_analyze()
pipe.pipe_parse()
md_content = pipe.pipe_mk_markdown(image_dir, drop_mode="none")
```

### 二次开发

TODO

# TODO

- [x] 基于模型的阅读顺序
- [x] 正文中列表识别
- [ ] 正文中代码块识别
- [x] 目录识别
- [x] 表格识别
- [ ] [化学式识别](docs/chemical_knowledge_introduction/introduction.pdf)
- [ ] 几何图形识别

# Known Issues

- 阅读顺序基于模型对文本在空间中的分布进行排序，在极端复杂的排版下可能会乱序
- 不支持竖排文字
- 目录和列表通过规则进行识别，少部分不常见的列表形式可能无法识别
- 标题只有一级，目前不支持标题分级
- 代码块在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
- 在一些公式密集的PDF上强制启用OCR效果会更好
- 如果您要处理包含大量公式的pdf,强烈建议开启OCR功能。使用pymuPDF提取文字的时候会出现文本行互相重叠的情况导致公式插入位置不准确。
