# 更新记录
- 2025/01/06 1.0.0 发布，这是我们的第一个正式版本，在这个版本中，我们通过大量重构带来了全新的API接口和更广泛的兼容性，以及全新的自动语言识别功能：
  - 全新API接口 
    - 对于数据侧API，我们引入了Dataset类，旨在提供一个强大而灵活的数据处理框架。该框架当前支持包括图像（.jpg及.png）、PDF、Word（.doc及.docx）、以及PowerPoint（.ppt及.pptx）在内的多种文档格式，确保了从简单到复杂的数据处理任务都能得到有效的支持。
    - 针对用户侧API，我们将MinerU的处理流程精心设计为一系列可组合的Stage阶段。每个Stage代表了一个特定的处理步骤，用户可以根据自身需求自由地定义新的Stage，并通过创造性地组合这些阶段来定制专属的数据处理流程。
  - 更广泛的兼容性适配
    - 通过优化依赖环境和配置项，确保在ARM架构的Linux系统上能够稳定高效运行。
    - 深度适配华为昇腾NPU加速，积极响应信创要求，提供自主可控的高性能计算能力，助力人工智能应用平台的国产化应用与发展。[NPU加速教程](docs/README_Ascend_NPU_Acceleration_zh_CN.md)
  - 自动语言识别
    - 通过引入全新的语言识别模型， 在文档解析中将`lang`配置为`auto`，即可自动选择合适的OCR语言模型，提升扫描类文档解析的准确性。
- 2024/11/22 0.10.0发布，通过引入混合OCR文本提取能力，
  - 在公式密集、span区域不规范、部分文本使用图像表现等复杂文本分布场景下获得解析效果的显著提升
  - 同时具备文本模式内容提取准确、速度更快与OCR模式span/line区域识别更准的双重优势
- 2024/11/15 0.9.3发布，为表格识别功能接入了[RapidTable](https://github.com/RapidAI/RapidTable),单表解析速度提升10倍以上，准确率更高，显存占用更低
- 2024/11/06 0.9.2发布，为表格识别功能接入了[StructTable-InternVL2-1B](https://huggingface.co/U4R/StructTable-InternVL2-1B)模型
- 2024/10/31 0.9.0发布，这是我们进行了大量代码重构的全新版本，解决了众多问题，提升了性能，降低了硬件需求，并提供了更丰富的易用性：
  - 重构排序模块代码，使用 [layoutreader](https://github.com/ppaanngggg/layoutreader) 进行阅读顺序排序，确保在各种排版下都能实现极高准确率
  - 重构段落拼接模块，在跨栏、跨页、跨图、跨表情况下均能实现良好的段落拼接效果
  - 重构列表和目录识别功能，极大提升列表块和目录块识别的准确率及对应文本段落的解析效果
  - 重构图、表与描述性文本的匹配逻辑，大幅提升 caption 和 footnote 与图表的匹配准确率，并将描述性文本的丢失率降至接近0
  - 增加 OCR 的多语言支持，支持 84 种语言的检测与识别，语言支持列表详见 [OCR 语言支持列表](https://paddlepaddle.github.io/PaddleOCR/latest/ppocr/blog/multi_languages.html#5)
  - 增加显存回收逻辑及其他显存优化措施，大幅降低显存使用需求。开启除表格加速外的全部加速功能(layout/公式/OCR)的显存需求从16GB降至8GB，开启全部加速功能的显存需求从24GB降至10GB
  - 优化配置文件的功能开关，增加独立的公式检测开关，无需公式检测时可大幅提升速度和解析效果
  - 集成 [PDF-Extract-Kit 1.0](https://github.com/opendatalab/PDF-Extract-Kit)
    - 加入自研的 `doclayout_yolo` 模型，在相近解析效果情况下比原方案提速10倍以上，可通过配置文件与 `layoutlmv3` 自由切换
    - 公式解析升级至 `unimernet 0.2.1`，在提升公式解析准确率的同时，大幅降低显存需求
    - 因 `PDF-Extract-Kit 1.0` 更换仓库，需要重新下载模型，步骤详见 [如何下载模型](docs/how_to_download_models_zh_cn.md)
- 2024/09/27 0.8.1发布，修复了一些bug，同时提供了[在线demo](https://opendatalab.com/OpenSourceTools/Extractor/PDF/)的[本地化部署版本](projects/web_demo/README_zh-CN.md)和[前端界面](projects/web/README_zh-CN.md)
- 2024/09/09 0.8.0发布，支持Dockerfile快速部署，同时上线了huggingface、modelscope demo
- 2024/08/30 0.7.1发布，集成了paddle tablemaster表格识别功能
- 2024/08/09 0.7.0b1发布，简化安装步骤提升易用性，加入表格识别功能
- 2024/08/01 0.6.2b1发布，优化了依赖冲突问题和安装文档
- 2024/07/05 首次开源

# 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**。

> 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

> [!NOTE]
> 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://mirrors.aliyun.com/pypi/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。

> [!TIP]
> 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：

> [!NOTE]
>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
    "layout-config": {
        "model": "doclayout_yolo" // 使用layoutlmv3请修改为“layoutlmv3"
    },
    "formula-config": {
        "mfd_model": "yolo_v8_mfd",
        "mfr_model": "unimernet_small",
        "enable": true  // 公式识别功能默认是开启的，如果需要关闭请修改此处的值为"false"
    },
    "table-config": {
        "model": "rapid_table",  // 默认使用"rapid_table",可以切换为"tablemaster"和"struct_eqtable"
        "enable": false, // 表格识别功能默认是关闭的，如果需要开启请修改此处的值为"true"
        "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
> [!IMPORTANT]
> Docker 需设备gpu显存大于等于8GB，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://gitee.com/myhloli/MinerU/raw/master/docker/china/Dockerfile -O Dockerfile
  docker build -t mineru:latest .
  docker run --rm -it --gpus=all mineru:latest /bin/bash -c "echo 'source /opt/mineru_venv/bin/activate' >> ~/.bashrc && exec bash"
  magic-pdf --help
  ```
### 使用NPU

如果您的设备存在NPU加速硬件，则可以通过以下教程使用NPU加速：

[NPU加速教程](docs/README_Ascend_NPU_Acceleration_zh_CN.md)

## 使用

### 命令行

[通过命令行使用MinerU](https://mineru.readthedocs.io/en/latest/user_guide/usage/command_line.html)

> [!TIP]
> 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

[通过Python代码调用MinerU](https://mineru.readthedocs.io/en/latest/user_guide/usage/api.html)


### 部署衍生项目

衍生项目包含项目开发者和社群开发者们基于MinerU的二次开发项目，
例如基于Gradio的应用界面、基于llama的RAG、官网同款web demo、轻量级的多卡负载均衡c/s端等，
这些项目可能会提供更多的功能和更好的用户体验。
具体部署方式请参考 [衍生项目readme](projects/README_zh-CN.md)


### 二次开发

TODO

# TODO

- [x] 基于模型的阅读顺序  
- [x] 正文中目录、列表识别  
- [x] 表格识别
- [ ] 正文中代码块识别
- [ ] [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可阅读内容在空间中的分布进行排序，在极端复杂的排版下可能会部分区域乱序
- 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
- 表格识别在复杂表格上可能会出现行/列识别错误
- 在小语种PDF上，OCR识别可能会出现字符不准确的情况（如拉丁文的重音符号、阿拉伯文易混淆字符等）
- 部分公式可能会无法在markdown中渲染
