IPython启动定制 [英] IPython startup customization

问题描述

我试图在Windows 7 64位计算机上的 IPython 启动时从__future__ import division 加载之类的内容， python 2.7 64位。

I am trying to load things like from __future__ import division on the IPython startup on windows 7 64 bit machine, python 2.7 64 bit.

我搜索了网页，我发现推荐的方法是放 .py 文件，说明如下： C：\ Users \ Me\.ipython\profile_default\startup 。我从__future__ import输入了一个简单的 .py 文件，其中包含

I searched the web and the recommended way I found is to put a .py file with instructions in: C:\Users\Me\.ipython\profile_default\startup. I've put a simple .py file containing

from __future__ import division
from __future__ import unicode_literals

在该文件夹中。但它实际上什么也没做。更令人困惑的是文件似乎执行，因为如果我在那里放一些随机错误行，我看到Ipython启动时出错。仍然没有导入除法，必须重新导入它，从shell中的__future__ import division 输入。

in that folder. But it actually does nothing. What is more confusing is that the file seems to execute, because if I put some random error line in there, i see an error on Ipython start. Still division is not imported and have to re-import it typing from __future__ import division in the shell.

I在 Anaconda 和 Winpython 上尝试了它（ IPython的设置在这个分布上是在其他文件夹中）具有相同的结果。我重新导入后一切正常。完全停留在这里，请帮助！

I tried it both on Anaconda and Winpython(settings for IPython on this distribution are in other folder) with the same result. After I re-import everything works fine. Totally stuck here, please help!

推荐答案

检查 C：\ Users \ Me \.ipython\profile_default\ipython_config.py 存在。如果没有，请运行

Check to see if C:\Users\Me\.ipython\profile_default\ipython_config.py exists. If it doesn't, run

ipython profile create

从命令行生成它。接下来，在您喜欢的文本编辑器中打开它，然后搜索 c.InteractiveShellApp.exec_lines 。取消注释该行（它是我文件中的第27行）并将其编辑为以下内容：

from the command line to generate it. Next, open it in your favorite text editor and search for c.InteractiveShellApp.exec_lines. Uncomment that line (it's line 27 in my file) and edit it to be the following:

c.InteractiveShellApp.exec_lines = ["from __future__ import division", "from __future__ import unicode_literals"]

保存文件，重新启动IPython，你应该全部设置。

Save the file, restart IPython, and you should be all set.
