Jupyter nbconvert LaTex导出主题 [英] Jupyter nbconvert LaTex Export Theme

问题描述

我正在使用Jupyter Notebook nbconvert(另存为菜单)通过Latex导出为pdf.但是，pdf文件格式不佳.例如，很好地显示了一些宽表.我希望有一个用于将表调整为页面宽度的框.是否可以使用任何样式，模板来制作精美的报告，以及如何要求nbconverter使用该样式?

I am using Jupyter Notebook nbconvert (Save as menu) to export as pdf via Latex. However, the pdf file is not in a good shape. For example, some wide tables are shown well. I would prefer to have a box for tables to be resized to the width of the page. Is there any style, template that I can use to have nice reports and how I may ask nbconverter to use that style?

这是Latex输出:

推荐答案

类似Pandas的版本在0.23版中获得了._repr_latex_()方法.您需要将pd.options.display.latex.repr=True设置为激活它.

Looks like Pandas gained a ._repr_latex_() method in version 0.23. You'll need to set pd.options.display.latex.repr=True to activate it.

没有乳胶代表:

与乳胶代表:

Without latex repr:

With latex repr:

查看选项使格式接近您想要的格式.为了完全匹配所需的输出，您需要使用自定义的乳胶模板.

Check out the options to get the formatting close to what you want. In order to match your desired output exactly, you'll need to use a custom latex template.

Edited to provide more information on templates:

从此处开始以获取有关模板的一般信息.您可以在与笔记本相同的路径中创建一个.tplx文件，并在以下命令行中运行nbconvert时将其指定为模板:!jupyter nbconvert --to python 'example.ipynb' --stdout --template=my_custom_template.tplx.另外，您可以通过修改~.jupyter目录中的jupyter_notebook_config.py文件，通过菜单指定导出为乳胶时要使用的默认模板.如果此文件尚不存在，则可以通过从命令行运行命令jupyter notebook --generate-config来生成它.我的模板也位于~/.jupyter目录中，因此我在jupyter_notebook_config.py中添加了以下内容:

Start here for general information about templates. You can create a .tplx file in the same path as your notebook and specify it as the template when running nbconvert from the command line: !jupyter nbconvert --to python 'example.ipynb' --stdout --template=my_custom_template.tplx. Alternatively, you can specify a default template to use when exporting as Latex via the menu by modifying the jupyter_notebook_config.py file in your ~.jupyter directory. If this file doesn't exist already, you can generate it by running the command jupyter notebook --generate-config from the command line. I have my template sitting in the ~/.jupyter directory as well, so I added the following to my jupyter_notebook_config.py:

# Insert this at the top of the file to allow you to reference
# a template in the ~.jupyter directory
import os.path
import sys
sys.path.insert(0, os.path.expanduser("~") + '/.jupyter')
# Insert this at the bottom of the file:
c.LatexExporter.template_file = 'my_template' # no .tplx extension here
c.LatexExporter.template_path = ['.', os.path.expanduser("~") + '/.jupyter'] # nbconvert will look in ~/.jupyter

要了解一些有关模板如何工作的信息，请先查看

To understand a bit about how the templates work, start by taking a look at null.tplx. The line ((*- for cell in nb.cells -*)) loops over all the cells in the notebook. The if statements that follow check the type of each cell and call the appropriate block.

其他模板扩展null.tplx.每个模板定义(或重新定义)一些块.层次结构为null->display_priority->document_contents->base->style_*->article.

The other templates extend null.tplx. Each template defines (or redefines) some of the blocks. The hierarchy is null->display_priority->document_contents->base->style_*->article.

您的自定义模板可能应该扩展article.tplx，并向标头中添加一些Latex命令，以所需的方式设置表.在此博客文章中查看有关设置自定义模板的示例

Your custom template should probably extend article.tplx and add some Latex commands to the header that sets up the tables the way you want. Take a look at this blog post for an example of setting up a custom template.
