本文介绍如何在ipython环境中实现已导入模块的自动加载与重新加载，包括使用%load_extautoreload和%autoreload2指令，以及在ipython启动时自动加载的方法。
部署运行你感兴趣的模型镜像

ipython很好用，但是如果在ipython里已经import过的模块修改后需要重新reload就需要这样

In [1]: %load_ext autoreload

In [2]: %autoreload 2

In [3]: from foo import some_function

In [4]: some_function()
Out[4]: 42

In [5]: # open foo.py in an editor and change some_function to return 43

In [6]: some_function()
Out[6]: 43

如果想在ipython每次启时自动加载，步骤如下
it may be necessary to generate one first:
1、运行下面的command用来产生ipython_config.py文件 

ipython profile create

2、gedit ~/.ipython/profile_default/ipython_config.py添加: 

c.InteractiveShellApp.exec_lines = []
c.InteractiveShellApp.exec_lines.append('%load_ext autoreload')
c.InteractiveShellApp.exec_lines.append('%autoreload 2')

技术背景 IPython是一个非常灵活好用的python终端工具，而且比Python自带的终端工具还多了命令行高亮和自动索引的功能，也是常用的Jupyter Notebook的基础工具。在使用IPython的过程中可以使用它的一些独有的功能——直接运行Shell命令行，和魔术命令。本文介绍的是其中一种魔术命令——重新加载函数模块。 魔术命令配置 在默认配置下，IPython在运行一个模块之前不会...

使用Django时，如果要测试单个python文件，需要使用python manage.py shell 但是如果修改了代码，需要退出，然后重新进入ipython环境，才可以加载新的代码 有没有办法自动重载修改后的代码？ 官网的解决方案，但是试了一下并没有用。 有没有哪位大神知道为什么？ In [1]: %load_ext autoreload In [2]: %autoreload

%load_ext autoreload %autoreload 2 %matplotlib inline A module that was compiled using NumPy 1.x cannot be run in NumPy 2.0.2 as it may crash. To support both 1.x and 2.x versions of NumPy, modules must be compiled with NumPy 2.0. Some module may need to rebuild instead e.g. with 'pybind11>=2.12'. If you are a user of the module, the easiest solution will be to downgrade to 'numpy<2' or try to upgrade the affected module. We expect that some modules will need time to support NumPy 2.
