§01 IPYNB文档

1.1 什么是IPYNB文档？

1.1.1 IPYNB应用

  IPYNB 是 Jupyter Notebook 文档格式，是一个交互式计算环境下帮助科研人员应用 Python 程序操作、分析数据的文档。它包含了基于WEB应用程序Jupyter Notebook 过程用于计算的输入、输出、数学函数、图片以及解释文字等等。 IPYNB文本可以转换成 .HTML, .PDF， reStructuredText 以及LaTex文档。

▲ 图1.1.1 IPYNB文档界面

1.1.2 IPYNB格式

  在 What is an IPYNB Files? 给出了IPYNB notebooks文件格式描述。 IPYNB文件格式是 纯文本文件（plain text） ， 使用 JSON 文件语法格式，方便人们阅读、分享。通常科研人员通常将它们的IPYNB文件在网络上发布并提供可以访问的 URLs ，这几大方便了其他 Jupyter Notebook 用户：

• 下载文档并在自己的Jupyter Notebook中运行；
• 利用在线Jupyter Notebook 浏览器进行阅读而不必另外安装其它软件。

1.1.3 IPYNB的含义

  Jupyter Notebook 的IPYNB文档通常被认为是IPYTHON NOTEBOOK ，所以它的文件扩展名被记做 .ipynb (IPy thon N ote B ook)，尽管最初IPYNB文件格式是用来支持IPython用户，不过现在主要是Jupyter Notebook 在支持IPython的是常闭使用。

1.1.4 打开IPYNB文档

  你可以在以下几个软件中打开IPYNB文档：

• Jupyter Notebook(跨平台)开发环境；
• Jpyter Notebook Viewer(Web)
• Cantor（Linux）
• Google Claboratory(Web)
• Microsoft Visual Studio Code ，这也是一个跨平台文本编辑器，可以创建、打开、保存Jupyter Notebook。

  如果使用Jupyter Notebook Viewer打开IPYNB文档，该文档需要被存储在网络上，比如使用 Github，或者其他文件存储服务器。

1.2 CSDN文档

  CSDN（Chinese Software Developer Network） 是国内软件技术开发人员交流的平台，它提供 富文本、Markdown 编辑器方便软件开发人员记录、分析自己的学习、研究内容。特别是它的 Markdown 编辑器 操作方便，功能强大，方便了工程技术人员书写和记录自己的思想与工作数据。

1.2.1 从IPYNB到Markdown

  现在有一些在线工具，方便将IPYNB格式的文档转换成Markdown文件。

• Vertopal — Free Online Converter
• Convert a Jupyter/IPython notebook to an R Markdown document
• Converting notebooks to other formats?
• Convert IPython Notebooks to markdown (and back) ：这个工具包是Github上的notedown软件包，它提供了将ipynb文档与markdown文档之间的来回的转换。

（1）nbconvert转换IPYNB文档

  根据 Converting notebooks to other formats?中给出了利用 nbconvert将IPYNB转换成 html, latex, pdf, slide, markdown, rst , script, notbook 格式的文档。

  基本语法：

$ ipython nbconvert --to FORMAT notebook.ipynb

  在 如何利用 nbconvert将 IPYNB文档转换 Markdown文档？ 给出了具体应用nbconvert命令转换IPYNB文档的 示例。它是将 飞桨AI Studio - 人工智能学习与实训社区 中的文档 基于自监督学习的目标检测伪标签生成 转换成Markdown文档，并上载到CSDN中。

1.2.2 从Markdown转换IPYNB

  将Markdown文档转换成IPYNB格式在很多场合是需要的：

• 希望将自己的Markdown记录的文件，特别是其中包含有处理代码分享给其他开发人员；
• 重新运行Markdown中的处理过程；

  特别是在一些场合，Markdown编辑器比直接在Jupyter Notebook进行编辑更加的方便，比如CSDN的Markdown编辑器就非常好。因此，将Markdown文档转换成IPYNB就可以达到让自己的 技术文档的得到更大分享的目标。

  在网络上也存在一个在线的将Markdown转换成IPYNB的程序：

• Convert TXT MARKDOWN to IPYNB
• Markdown for Jupyter notebooks cheatsheet ：介绍了如何直接将Markdown的Cells添加到Jupyter Notebook。
• Convert IPython Notebooks to markdown (and back) ：这个工具包notedown提供了在ipynb与markdown文档之间的转换的功能。

  在博文 如何利用 notedown 完成 ipynb与markdown之间的格式转换？ 测试了notedown软件将Markdown文件转换成jpynb文档。但是发现：

• 对于CSDN中的Markdown文本格式中扩增的关于图片尺寸、显示位置的支持语法，在转换之后在Jupyter Notebook中并不支持；
• 对于CSDN中的Markdown代码，格式修饰都都可以很好的支持；

  因此，需要增加额外的格式过滤处理，将CSDN中的Markdown文档进行格式过滤。

  在 怎么在CSDN中写微信公众号推文？ 介绍了将CSDN文档转换成 墨滴文档 ，转换转换成微信推文格式。因此可以应用上述转换过程，再加上notedown的功能，联合形成ipynb格式。

§02 CSDN→IPYNB

2.1 转换方案

  根据【01】中初步实验，通过notedown软件在转换CSDN导出的Markdown文档过程中会对于CSDN中的增强功能的格式不适应，所以需要进行格式的过滤。根据 将CSDN Markdown文档转换成MDNICE文档 方式，利用它程序（cd2md）框架，将CSDN中的Markdown文本进行过滤处理，存储在临时文件中。然后再调用notedown进行转换。

2.1.1 修改cd2md

  在cd2md文件中，增加新的命令选项：

cd2md >csdn

  如果有**>** 符号，代表将对应内容写入文件 csdn.md中，注意 csdn是缺省的选项。

  在打开文件写入的时候，需要将带有中文的信息通过bytes函数写入，否则就会出现乱码。

outfile = os.path.join(r'd:\temp', outfilename)
with open(outfile, 'wb') as f:f.write(bytes(pastestr, 'utf-8'))printf("Output markdown file to %s.\a"%outfilename)

2.1.2 调用notedown进行转换

  调用os.system执行notedown将 Markdown文件转换成ipynb文件。

printf("Convert markdown to __ipynb__.\a")
os.system(r'notedown d:\temp\csdn.md > d:\temp\csdn.ipynb')

2.2 转换测试

  测试 测试录制的电话拨码声音信号在发送过程中的问题 文档。执行如下命令：

cd2md >

  便可以生成 csdn.ipynb。调入BML CodeLab中，使用Notebook打开，可以看到文档转换后的格式很完美。

※ 转换总结 ※

  IPYNB格式的文档可以很方便在Jupyter Notebook环境内方便研究人员对于算法、数据进行操作。Markdown文本则便于形成各种网络文档。本文介绍了利用notedown实现将CSDN中的Markdown文件转换成IPYNB文档。利用它可以方便对于CSDN中的研究文档进一步实验。
