从自身内部以编程方式保存IPython笔记本吗? [英] Save an IPython notebook programmatically from within itself?

问题描述

我想让IPython笔记本运行以进行一些计算并显示一些视觉效果.

I would like to leave an IPython notebook running to do some computation + show some visuals.

一旦IPython笔记本完成，我希望IPython笔记本中的最后一个单元以编程方式保存IPython笔记本.然后，我想将笔记本(包含所有输出)复制到另一个目录中，以记录结果.

Once the IPython notebook has finished, I want the last cell in the IPython notebook to programmatically save the IPython notebook. Then I want to copy the notebook (with all output) to another directory to keep a record of results.

我可以轻松地编写复制位，但是我不确定如何获得IPython笔记本以编程方式保存自身?这可能吗?预先感谢！

The copying bit I can code up easily, but I am not sure how to get an IPython notebook to programatically save itself? Is this possible? Thanks in advance!

推荐答案

我接受@Taar的评论，并使其成为实际的答案，因为它适用于提出问题的原始人和我自己.

I am taking @Taar's comment and making it an actual answer since it worked for the original person who asked the question and for myself.

from IPython.display import display, Javascript
display(Javascript('IPython.notebook.save_checkpoint();'))

这将创建检查点-与 CTRL-s 相同.

This will create checkpoints - same thing as CTRL-s.

注意:在Jupiter中，CTRL-s触发一个异步过程，并且文件保存实际上仅在几秒钟后完成.如果要在笔记本中执行阻止保存操作，请使用此小功能( file_path 是笔记本文件的路径):

Note: in Jupiter, CTRL-s triggers an async process and the file save is actually completed only a few seconds later. If you want a blocking save operation in a notebook, use this little function (file_path is the path to the notebook file):

import time
from IPython.display import display, Javascript
import hashlib

def save_notebook(file_path):
    start_md5 = hashlib.md5(open(file_path,'rb').read()).hexdigest()
    display(Javascript('IPython.notebook.save_checkpoint();'))
    current_md5 = start_md5
    
    while start_md5 == current_md5:
        time.sleep(1)
        current_md5 = hashlib.md5(open(file_path,'rb').read()).hexdigest()
