ipython%存储魔术不起作用

我试图让我的ipython别名持久化,并且根据文档,%store magic函数提供此功能.但这对我不起作用.

wim@SDFA100461C:/tmp$ echo 'print("hello world!")' > test.py
wim@SDFA100461C:/tmp$ ipython
In [1]: alias potato python /tmp/test.py

In [2]: potato
hello world!

In [3]: %store potato
Alias stored: potato (python /tmp/test.py)

In [4]: 
Do you really want to exit ([y]/n)? 
wim@SDFA100461C:/tmp$ ipython
In [1]: potato
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
 in ()
----> 1 potato

NameError: name 'potato' is not defined

我正在使用IPython 1.1.0/Python 2.7.5+
