为Jupyter Notebook预加载特定的类/功能 [英] Preloading the Jupyter Notebook with specific classes/functions

问题描述

我想预装一个笔记本中具有在其他文件中定义的特定类/功能的笔记本.更具体地说，我想使用python(类似于加载配置文件，其中包含所有相关的类/函数)进行此操作.目前，我正在使用python生成笔记本，并在服务器上自动启动它们.由于不同的配置文件"需要这些笔记本，因此它们需要不同的类和功能，而无需专门导入它们.

I'd like to preload a notebook with specific classes/functions that I've defined in another file. More specifically, I'd like to do this with python (something like loading a profile, containing all relevant classes/functions). Currently, I'm generating notebooks with python and starting them automatically on the server. Because different "profiles" need these notebooks, they need different classes and functions without specifically importing them.

在生成jupyter笔记本时，我只需将jupyter笔记本模板"复制到特定文件中，然后让用户自动打开它. 我可以在其中设置某种配置文件吗?

When generating a jupyter notebook, I simply copy a jupyter notebook "template" to a specific file and let the user open this automatically. Can I set some sort of profile in

"metadata": {
  "kernelspec": {
   "display_name": "Python 3",
   "language": "python",
   "name": "python3",
   "profile": "lab_5" // <-- 
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 2
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython2",
   "version": "2.7.13"
  }
 },

其中"lab_5"将预加载必要的类?

where "lab_5" would preload the necessary classes?

推荐答案

启动Jupyter Notebook(或实验室)时，如果其中包含python脚本文件

When you start Jupyter notebook (or lab), if you have python script file(s) in

location_of_ipython_profile/startup/

然后它们将在每次IPython启动时运行(用作标准ipython内核).例如，在我的机器上，我有一个名为00-first.py的文件，它的内容如下:

then they will run on every IPython startup (to serve as standard ipython kernel). For example, on my machine I have a file named 00-first.py and it has simple content as follows:

import numpy as np

如果还有其他脚本，例如50-middle.py和99-last.py，它们也会连续运行.

If there are other scripts, say, 50-middle.py and 99-last.py, they also run consecutively.

当我使用ipython内核打开一个新的Jupyter笔记本时.我将根据这些脚本文件预先执行许多操作.对于第一个脚本00-first.py，它提供了符号np，可以立即使用.因此，我可以运行print(np.pi)并获取3.141592...作为输出.

When I open a new Jupyter notebook with ipython kernel. I will have many thing pre-executed according to those script files. For the first script, 00-first.py, it provides the symbol np to use right away. So, I can run print(np.pi) and get 3.141592... as output.

要获取location_of_ipython_profile，可以在Jupyter笔记本上运行magic命令:

To get the location_of_ipython_profile, one can run magic command on Jupyter notebook:

!ipython locate profile

就我而言，我得到C:\Users\swatc\.ipython\profile_default.要列出startup文件夹中的所有文件，我运行:

In my case, I get C:\Users\swatc\.ipython\profile_default. To list all the files in the startup folder, I run:

!dir C:\Users\swatc\.ipython\profile_default\startup\*.*

请记住，您的计算机上可能有多个python配置文件.以上所有内容均对默认配置文件有效.

Remember that there can be several python profiles on your computer. All the above is valid for the default profile.
