ipynb to pdf
Q: 如何把jupyter notebook 转为 pdf 文档?
A: 尝试了几种python包, 结果都没有成功. 包括: xhtml2pdf,
查看官方的介绍说用pandoc也是一种方法, 但是觉得安装一个可怕的Latex和pandoc太麻烦了.
还好, 找到了一个开源方法: 用wkhtmltopdf 程序.
用python写一个脚本, 调用wkhtmltopdf, 运行命令行指令, 得以实现. 非常符合我的预期. 简明, 优雅.
wkhtml2pdf 简介
wkhtmltopdf，一个集成好了的exe文件（C++编写），
基本的调用方法是:
"c:\Program Files\bin\wkhtmltopdf.exe" https://github.com/mementum/backtrader/blob/master/docs2/signal_strategy/signal_strategy.rst signal_strategy.pdf

可以先在命令行测试一下，有其他的需要, 可以在命令行通过wkhtmltopdf --help查询，
如果是超长页的话，可以用命令:
wkhtmltopdf.exe http://passport.yupsky.com/ac/register e:\yupskyreg.pdf -H --outline
Here:
-H 是显示扩展帮助
--outline 是添加pdf的左侧概要！(缺省设置)
而且可以批量生成哦，中间用空格隔开
python 脚本: (封装了运行wkhtml2pdf.exe 命令行的py脚本)

IPython/Jupyter Problems saving notebook as PDF - Stack Overflow
http://stackoverflow.com/questions/29156653/ipython-jupyter-problems-saving-notebook-as-pdf
This Python script has GUI to select with explorer a Ipython Notebook you want to convert to pdf.
The approach with wkhtmltopdf is the only approach I found works well and provides high quality pdfs.
Other approaches described here are problematic, syntax highlighting does not work or graphs are messed up.
You'll need to install wkhtmltopdf: http://wkhtmltopdf.org/downloads.html
and Nbconvert
pip install nbconvert
# OR
conda install nbconvert

# This will create both an HTML and a PDF file
import subprocess
import os
from Tkinter import Tk
from tkFileDialog import askopenfilename
WKHTMLTOPDF_PATH = "C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf" # or wherever you keep it
def export_to_html(filename):
cmd = 'ipython nbconvert --to html "{0}"'
subprocess.call(cmd.format(filename), shell=True)
return filename.replace(".ipynb", ".html")
def convert_to_pdf(filename):
cmd = '"{0}" "{1}" "{2}"'.format(WKHTMLTOPDF_PATH, filename, filename.replace(".html", ".pdf"))
subprocess.call(cmd, shell=True)
return filename.replace(".html", ".pdf")
def export_to_pdf(filename):
fn = export_to_html(filename)
return convert_to_pdf(fn)
def main():
print("Export IPython notebook to PDF")
print(" Please select a notebook:")
Tk().withdraw() # Starts in folder from which it is started, keep the root window from appearing
x = askopenfilename() # show an "Open" dialog box and return the path to the selected file
x = str(x.split("/")[-1])
print(x)
if not x:
print("No notebook selected.")
return 0
else:
fn = export_to_pdf(x)
print("File exported as:\n\t{0}".format(fn))
return 1
main()
这里也记录一下尝试xhtml2pdf的经过.
安装完了以后, 编写脚本, 运行时主要是: 卡在了html5lib这个包里:
异常是:
inputstream
CSS parser
等等.
搞定不了, 所以放弃之.
