导入错误:没有命名为numpy的模块

I have a very similar question to this question, but still one step behind. I have only one version of Python 3 installed on my Windows 7 (sorry) 64-bit system.

我有一个和这个问题很相似的问题，但是仍然落后一步。我只有一个版本的Python 3安装在我的Windows 7(抱歉)64位系统上。

I installed numpy following this link - as suggested in the question. The installation went fine but when I execute

我在这个链接后面安装了numpy，这是问题中的建议。安装进行得很顺利，但当我执行时

import numpy

I got the following error:

我得到以下错误:

Import error: No module named numpy

导入错误:没有命名为numpy的模块

I know this is probably a super basic question, but I'm still learning.

我知道这可能是一个非常基本的问题，但我还在学习。

Thanks

谢谢

Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.

在NumPy版本1.5.0中添加了对Python 3的支持，所以首先，您必须下载/安装更新的NumPy版本。

You installed the Numpy Version for Python 2.6 - so you can only use it with Python 2.6. You have to install Numpy for Python 3.x, e.g. that one: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-win32-superpack-python3.2.exe/download

您为Python 2.6安装了Numpy版本——因此只能在Python 2.6中使用它。您必须为Python 3安装Numpy。例如:http://sourceforge.net/projects/numpy/files/numpy/1.6.1 /numpy-1.6.1- win6.2 -superpack-python3.2.exe/download

For an overview of the different versions, see here: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/

有关不同版本的概述，请参见这里:http://sourceforge.net/projects/numpy/files/numpy/numpy/1.6.1 /

I also had this problem (Import Error: No module named numpy) but in my case it was a problem with my PATH variables in Mac OS X. I had made an earlier edit to my .bash_profile file that caused the paths for my Anaconda installation (and others) to not be added properly.

我也有这个问题(导入错误:没有模块命名numpy),但就我而言这是一个问题,我的路径变量在Mac OS x我之前做了一个编辑. bash_profile文件导致路径为我的蟒蛇安装(和其他人)不能正常添加。

Just adding this comment to the list here in case other people like me come to this page with the same error message and have the same problem as I had.

只要把这个注释添加到这里的列表中，以防像我这样的人带着同样的错误信息来到这个页面，并且遇到和我一样的问题。

I had this problem too after I installed Numpy. I solved it by just closing the Python interpreter and reopening. It may be something else to try if anyone else has this problem, perhaps it will save a few minutes!

我在安装Numpy之后也遇到了这个问题。我通过关闭Python解释器并重新打开来解决这个问题。如果其他人有这个问题，也许可以尝试别的方法，也许可以节省几分钟!
