将 IPython 笔记本转换为 PDF

Question

我写了一个很长的 IPython notebook，需要把它转换成 PDF 来分发。我已阅读 this thread，但该解决方案对我不起作用。

我尝试了以下方法：

1. 如果我在浏览器中使用“打印”按钮，我将拥有所有 IPython 菜单 等显示，我不能接受。

2. 如果我使用 IPython 菜单中的打印预览，则不会呈现任何 LaTeX 方程。它们仍然只是 LaTeX 代码。

3. 如果我使用ipython nbconvert --to latex --post pdf myfile.ipynb，我会得到FileNotFoundError。追溯如下：

[NbConvertApp] Using existing profile dir: 'C:\\Users\\blokeley\\.ipython\\profile_default'

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:

我在 Windows 7 Professional 上使用 Python 3.4 64 位 Anaconda 的最新更新。

您的问题是您的计算机上没有安装 LaTeX。当subprocess 尝试调用pdflatex myfile.tex 时，它会失败，因为它找不到pdflatex。

虽然您可以在不需要 LaTeX 的情况下从 IPython 笔记本创建 .tex 文件，但这些只是包含 LaTeX 代码的文件。要编译它们以创建 PDF，您需要一个 LaTeX 版本。

在 Windows 上安装 LaTeX 并不难，MiKTeX 是一种可能的安装方式。
