如何在没有输出的情况下打开IPython笔记本？ [英] How can I open an IPython notebook without the output?

问题描述

我有一台IPython笔记本，我不小心丢弃了一个巨大的输出（15英寸MB），导致笔记本电脑崩溃。现在，当我打开笔记本电脑并试图删除麻烦的电池时，笔记本电脑再次崩溃 - 从而阻止我解决问题并恢复笔记本电脑的稳定性。

I have an IPython notebook where I've accidentally dumped a huge output (15 MB) that crashed the notebook. Now when I open the notebook and attempt to delete the troublesome cell, the notebook crashes again—thus preventing me from fixing the problem and restoring the notebook to stability.

最好修复我能想到的是手动将输入单元格粘贴到新笔记本上，但有没有办法只打开笔记本没有任何输出？

The best fix I can think of is manually pasting the input cells to a new notebook, but is there a way to just open the notebook without any outputs?

推荐答案

有一个很好的片段（我用作git提交钩子）去除ipython笔记本的输出：

There is this nice snippet (that I use as a git commit hook) to strip the output of an ipython notebook:

#!/usr/bin/env python

def strip_output(nb):
    for ws in nb.worksheets:
        for cell in ws.cells:
            if hasattr(cell, "outputs"):
                cell.outputs = []
            if hasattr(cell, "prompt_number"):
                del cell["prompt_number"]


if __name__ == "__main__":
    from sys import stdin, stdout
    from IPython.nbformat.current import read, write

    nb = read(stdin, "ipynb")
    strip_output(nb)
    write(nb, stdout, "ipynb")
    stdout.write("\n")

你可以轻松地使它变得更好用，目前您必须将其称为

You can easily make it a bit nicer to use, currently you'd have to call it as

strip_output.py < my_notebook.ipynb > my_notebook_stripped.ipynb
