我正在考虑使用*。Ipynb文件作为真相的来源,并以编程方式将它们“编译”为.py文件,用于计划的作业/任务。
我所理解的做到这一点的唯一方法是通过GUI。有没有办法通过命令行来实现?

我遇到了这个问题,并试图在网上找到解决方案。虽然我找到了一些解决方案,但它们仍然存在一些问题,例如,当你从仪表板启动一个新笔记本时,烦人的Untitled.txt自动创建。
所以最终我写出了自己的解决方案:
import io
import os
import re
from nbconvert.exporters.script import ScriptExporter
from notebook.utils import to_api_path
def script_post_save(model, os_path, contents_manager, **kwargs):
"""Save a copy of notebook to the corresponding language source script.
For example, when you save a `foo.ipynb` file, a corresponding `foo.py`
python script will also be saved in the same directory.
However, existing config files I found online (including the one written in
the official documentation), will also create an `Untitile.txt` file when
you create a new notebook, even if you have not pressed the "save" button.
This is annoying because we usually will rename the notebook with a more
meaningful name later, and now we have to rename the generated script file,
too!
Therefore we make a change here to filter out the newly created notebooks
by checking their names. For a notebook which has not been given a name,
i.e., its name is `Untitled.*`, the corresponding source script will not be
saved. Note that the behavior also applies even if you manually save an
"Untitled" notebook. The rationale is that we usually do not want to save
scripts with the useless "Untitled" names.
"""
# only process for notebooks
if model["type"] != "notebook":
return
script_exporter = ScriptExporter(parent=contents_manager)
base, __ = os.path.splitext(os_path)
# do nothing if the notebook name ends with `Untitled[0-9]*`
regex = re.compile(r"Untitled[0-9]*$")
if regex.search(base):
return
script, resources = script_exporter.from_filename(os_path)
script_fname = base + resources.get('output_extension', '.txt')
log = contents_manager.log
log.info("Saving script at /%s",
to_api_path(script_fname, contents_manager.root_dir))
with io.open(script_fname, "w", encoding="utf-8") as f:
f.write(script)
c.FileContentsManager.post_save_hook = script_post_save
要使用这个脚本,你可以将它添加到~/.jupyter/jupyter_notebook_config.py:)
请注意,您可能需要重新启动jupyter笔记本/实验室才能工作。

下面是一个jq解决方案,可能在某些情况下有用。记住,笔记本只是json。
jq -r '.cells[] | select(.cell_type == "code") | .source[] | rtrimstr("\n")' $filename
遵循前面的例子,但是使用了新的nbformat lib版本:
import nbformat
from nbconvert import PythonExporter
def convertNotebook(notebookPath, modulePath):
with open(notebookPath) as fh:
nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)
exporter = PythonExporter()
source, meta = exporter.from_notebook_node(nb)
with open(modulePath, 'w+') as fh:
fh.writelines(source.encode('utf-8'))
用于转换所有*。Ipynb将当前目录下的文件递归格式化为python脚本:
for i in *.ipynb **/*.ipynb; do
echo "$i"
jupyter nbconvert "$i" "$i"
done
有一个非常好的包叫做nb_dev,它是为在Jupyter notebook中编写Python包而设计的。与nbconvert一样,它可以将笔记本转换为.py文件,但它更灵活、更强大,因为它有许多不错的额外创作功能,可以帮助您在PyPI上开发测试、文档和注册包。它是快速发展起来的。人工智能的人。
它有一点学习曲线,但文档很好,总体上不难。
如果你不想每次保存时都输出一个Python脚本,或者你不想重新启动IPython内核:
在命令行中,你可以使用nbconvert:
$ jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb
作为一种技巧,您甚至可以通过预先挂起在IPython笔记本中调用上述命令!(用于任何命令行参数)。在笔记本里:
!jupyter nbconvert --to script config_template.ipynb
在添加——to脚本之前,选项是——to python或——to=python,但在转向语言无关的笔记本系统时,它被重命名了。
