在 python 3.11 下 安装 magic-pdf[full] 得到 0.6.1 版本。 python 3.10 下 安装 magic-pdf[full-cpu] 得到 1.10 版本。 参数还不一样。 搞不清楚开发者 怎么规划的。
magic-pdf -p "en.pdf" -o mkd -m auto 根据提示缺少组件， 挨个装上

出错后，研究 minerU 使用的核心组件 PDF-Extract-Kit
pdf-extract-kit paddle paddleocr pdf2markdown.py（效果不佳）-CSDN博客
更改了一些库的版本， ultralytics>=8.2.85 doclayout-yolo==0.0.2b1 unimernet==0.2.1 paddlepaddle==2.5.2 paddleocr==2.7.3
/usr/local/py310/bin/magic-pdf -p "cn.pdf" -o mkd -m auto -l ch -d true
中文 pdf 也成功了。
