pdf - 如何通过 Latex 将 Jupyter 笔记本转换为 PDF？

Question

我正在尝试使用 nbconvert 通过 Latex 将 Jupyter 笔记本转换为 pdf ，以便自动包含对单独 .bib 文件中包含的文章的引用。我按照这里的教程/示例工作。此处的 nbconvert 文档中建议了此类教程。

我在运行 Jupyter 笔记本的同一目录中有以下文件：

• citations.tplx（用于包含参考书目的模板）

• references.bib（包含引文的 .bib 文件，取自 Google Scholar）

在 markdown 单元格中，我使用以下语法来引用一个作品：

<cite data-cite="cortez2009modeling">(Cortez, 2009)</cite>

其中 .bib 文件中的此类工作报告如下：

@article{cortez2009modeling,
  title={Modeling wine preferences by data mining from physicochemical properties},
  author={Cortez, Paulo and Cerdeira, Ant{\'o}nio and Almeida, Fernando and Matos, Telmo and Reis, Jos{\'e}},
  journal={Decision support systems},
  volume={47},
  number={4},
  pages={547--553},
  year={2009},
  publisher={Elsevier}
}

在同样保存在同一位置的新笔记本中，我运行以下命令，该命令也是上述教程所采用的：

%%bash
jupyter nbconvert --to latex --template citations.tplx --post pdf my_notebook.ipynb

我得到一个很长的输出，充满了警告，但基本上，错误是： ModuleNotFoundError: No module named 'pdf'

我也尝试根据网络上的其他教程来执行此操作，但即使确实生成了 PDF 文件（使用略有不同的 nbconvert 命令），我的引文也没有在文本中捕获（而是出现一个问号），并且文件末尾没有参考书目。警告会说 Bibtex 存在“问题”，但仅此而已。

在下文中，我报告了我上面编写的命令的完整输出：

任何人都可以对此有所了解吗？我真的不明白为什么它不起作用。非常感谢您提前。
