在IPython笔记本中显式加载AMSmath会导致“[Math Processing Error]” [英] Loading AMSmath explicitly in IPython notebook causes "[Math Processing Error]"

问题描述

我是一个相对较新的IPython Notebook用户，我使用的是IPython 3.2.1。如此前瞻，如果我没有仔细阅读一些文档，我表示歉意！

我正在尝试在我的笔记本中排版一些LaTeX用于演示。我试图更好地利用MathJax功能，而不是默认使用的（假设）可用，因此尝试将MathJax附带的其他扩展明确地结合在一起。特别是，我尝试让我的IPython Notebook通过以下步骤加载AMScd.js，AMSsymbols.js和unicode.js：

1. 从最新的MathJax（v2.5）源获取这些扩展名的.js文件


2. 将它们添加到我的〜/ .ipython / nbextensions


3. 通过附加 IPython.load_extensions（AMScd）等修改〜/ .ipython / profile_< mine> / static / custom中的custom.js。

现在，所有这些工作正常，我能够在我的IPython笔记本中很好地排版交换图。所以，尽管如此，我决定还包括/加载MathJax附带的AMSmath.js，这是有问题的。 （对我来说，这似乎是一件很自然的事情，因为其他扩展可以很好地工作！）但是，试图通过包含AMSmath.js IPython.load_extensions（AMSmath）导致我的笔记本中的LaTeX数学在任何地方显示 [数学处理错误] 。这是我的最小示例和输出，包括和不包括 IPython.load_extensions（AMSmath）。

加价：

  ##最小工作示例
 
 \\ [ 
 \Delta u = f \text {on} \ Omega 
 \\] 
  

（我非常想在这里包含图片，唉，我不是社区的积极参与者，这使我甚至没有10个声誉！）

那么，我在这里错过了什么？为什么包含AMSmath会有问题？任何帮助，将不胜感激！谢谢！

解决方案

无需额外配置即可使用。看看

如何加载？

IPython / Jupyter笔记本预加载一些 MathJax扩展包括您要加载的扩展程序。此扩展名不是IPYthon / Jupyter扩展名，因此如果您尝试将此MathJax扩展名加载为IPython / Jupyter扩展名，则该扩展名不应该有效。请参见此处了解有关如何加载其他MathJax扩展的更多信息。

I am a relatively new IPython Notebook user and I am using IPython 3.2.1. So upfront, my apologies if I did not read some documentation carefully!

I am trying to typeset some LaTeX in my Notebook intended for a presentation. I tried to utilize MathJax capabilities better than what's (supposedly) available by default and so tried incorporating other extensions that come with MathJax explicitly. In particular, I tried getting my IPython Notebook to load AMScd.js, AMSsymbols.js and unicode.js through the following sequence of steps:

1. Obtain the .js files for these extensions from the latest MathJax (v2.5) source
2. Add them to my ~/.ipython/nbextensions
3. Modify custom.js in ~/.ipython/profile_<mine>/static/custom by appending IPython.load_extensions("AMScd"), etc.

Now, all these work fine, and I am able to typeset commutative diagrams nicely in my IPython notebook. So, while at all this, I decided to also include/load AMSmath.js that comes along with MathJax and this is problematic. (To me, this seems like a natural thing to do given that other extensions work well!) However, attempting to include AMSmath.js via IPython.load_extensions("AMSmath") causes LaTeX math in my Notebook to display [Math Processing Error] everywhere. Here's my minimal example and the output with and without including IPython.load_extensions("AMSmath").

Markup:

## A minimal working example

\\[
\Delta u = f \text{ on } \Omega
\\]

(I would totally like to include images here, alas, my not being an active participant in the community here leaves me with not even 10 reputation!)

So, what am I missing here? Why is this inclusion of AMSmath problematic? Any help would be appreciated! Thanks!

解决方案

It should work without extra configuration. Have a look here.

Your example in a markdown cell should be

(If you want the equation inline you can use $...$)

Inline equation $\Delta u = f \text{ on } \Omega$

(Or if you want the equation centered in their own line you can use $$...$$)

$$\Delta u = f \text{ on } \Omega$$

The result of both snippets in the same markdown cell is rendered as:

How it is loaded?

IPython/Jupyter notebook preloads some MathJax extensions including the extension you want to load. This extension is not an IPYthon/Jupyter extension so it shouldn't work if you try to load this MathJax extension as an IPython/Jupyter extension. See here to know more about how to load other MathJax extensions.
