ImportError: No module named numpy

I'm trying to run a program that requires Numpy to be installed. I thought it was, because if I try sudo apt-get install python-numpyit tells me that
我正在尝试运行一个需要安装 Numpy 的程序。我以为是，因为如果我尝试sudo apt-get install python-numpy它会告诉我
sudo apt-get install python-numpy

python-numpy is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
But then when I go to install the program I'm trying to (within that programs directory, where setup.py is located) I get:
但是当我去安装我想要安装的程序时（在 setup.py 所在的程序目录中）我得到：
python setup.py install
Traceback (most recent call last):
File "setup.py", line 20, in <module>

from numpy import array, asarray, float64, ones, zeros, int32,all,any, shape
ImportError: No module named numpy
When I look in the Python-2.7.3/Lib/site-packages directory the only thing that's in there is a README file. Shouldn't there be stuff from Numpy in there (and other install Python modules)?
当我查看 Python-2.7.3/Lib/site-packages 目录时，只有一个 README 文件。那里不应该有来自 Numpy 的东西（和其他安装 Python 模块）吗？
I am running Ubuntu 12.04 with Python 2.7
我正在使用 Python 2.7 运行 Ubuntu 12.04
Using dpkg -l python-numpyI get:
使用dpkg -l python-numpy我得到：

You do not mention where you are running the commands. For the commands, I guess you are using Ubuntu 12.10.
你没有提到你在哪里运行命令。对于命令，我猜您正在使用Ubuntu 12.10.
In Ubuntu 12.10 the default is Python3 (check it with python --version). So that, when you ran python setup ..., you are running it with the default python available. For what it is worth, weblog 3.3 requires Python 2.5, 2.6 or 2.7.
在 Ubuntu 12.10 中，默认值为 Python3（使用 进行检查python --version）。因此，当您运行 时python setup ...，您正在使用默认的 python 运行它。就其价值而言，weblog 3.3 需要 Python 2.5、2.6 或 2.7。
Also, you can check where python-numpy was installed (check it with dpkg -L python-numpy).
此外，您可以检查 python-numpy 的安装位置（使用 进行检查dpkg -L python-numpy）。
My shot out of the blue would be:
我的出手将是：
$ python2.7 setup.py install
If you do not have installed python2.7, you should install it (likely, the shell is going to suggest it).
如果你还没有安装python2.7，你应该安装它（很可能，shell会建议它）。
