python - Python - 安装 Scitools（std 似乎缺失）

Question

我已经从 sourceforge (mac osx 10.7) 安装了适用于 Python 2.7 的 SciTools 包。当我像这样导入它时，它不会出错。

import scitools

但是当我尝试像这样导入时（就像在课堂上展示的那样）：

from scitools.std import *

我收到以下错误：

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    from scitools.std import *
ImportError: No module named std

任何人都知道可能出了什么问题？

Answer 1

Your scitools version is too old. The scitools.std module was not introduced until version 0.6.

You have version 0.3 instead, where it is still called scitools.all. From the ChangeLog:

Version 0.6:

[...]

• The all module is renamed to std, i.e.,

  from scitools.all import *
  

  should now read

  from scitools.std import *
  

  The old name "all" is still available as a synonym for std, implying that old programs will work. (The "all" name is misleading as only a small portion of scitools is actually imported.)

You may want to upgrade your scitools installation to 0.9, the most recent release.
