始终使用某些选件/软件包装载Jupyter笔记本电脑 [英] Always have Jupyter notebook load with certain options / packages

问题描述

是否有一种方法可以确保jupyter笔记本始终以以下任意一种开头:

Is there a way to ensure that jupyter notebook always starts with either:

1)某些软件包已导入 和/或 2设置了某些选项

1) Certain packages imported and/or 2 Certain options set

我不想每次在运行的每个笔记本的顶部都键入相同的内容-例如始终使用numpy或pandas.

I don't want to have to type the same things everytime at the the top of each notebook I run - e.g. always using numpy or pandas.

此外，我始终希望每个单元都能看到多个输出.我使用以下代码使它正常工作，但是我希望将其保存为某种模板，不需要我每次手动键入.

Additionally, I always want to be able to see multiple output per cell. I use the following code to let this work just fine, but I want this saved as some sort of template, that doesn't require manual effort from me to type each time.

谢谢！

InteractiveShell.ast_node_interactivity = "all"

推荐答案

首先，找到startup文件夹的位置.

First, you find where the startup folder is located.

# on Jupyter notebook
import IPython
IPython.paths.get_ipython_dir()

在Windows上，响应为u'C:\\Users\\yourname\\.ipython'，而在Linux ~/.ipython上.

On Windows, the response is u'C:\\Users\\yourname\\.ipython', while on Linux ~/.ipython.

在该位置，有配置文件文件夹.至少您的计算机上有一个profile_default.每个配置文件文件夹中都存在一个startup文件夹.

In that location, there are profile folders. At least, there is a profile_default on your computer. One startup folder exists in each profile folder.

您将python脚本文件放在该文件夹中(我的情况是:C:/Users/myname/.ipython/profile_default/startup).

You put a python script file in that folder (my case: C:/Users/myname/.ipython/profile_default/startup).

我将脚本文件命名为00-first.py，并将以下代码放入其中:

I name my script file 00-first.py, and put this code in it:

import numpy as np
import pandas as pd

当我使用默认配置文件启动Jupyter笔记本服务器时，将在打开Jupyter笔记本之前执行启动脚本.

When I start the Jupyter notebook server with the default profile, the startup script will be executed prior to opening a Jupyter notebook.

在新打开的Jupyter笔记本上，您可以使用numpy和pandas(分别作为np，pd)，而无需先导入它们.

On a newly open Jupyter notebook, you can use numpy and pandas (as np, pd) without importing them first.

print(np.pi) #3.141592...
