[英]Numpy Install Mac Osx Python
I am using Python for my Linear Algebra course for programming. 我正在使用Python进行线性代数课程的编程。 For the tools we need, I am trying to install NumPy.
对于我们需要的工具,我正在尝试安装NumPy。 I used this website to guide me through the installation process.
我用这个网站来指导我完成安装过程。
I started from the links on SciPy's OS X page and eventually arrived at the SourceForge download site . 我从SciPy OS X页面上的链接开始,最终到达SourceForge下载站点 。
From there, I chose the Mac OS X installer numpy-1.6.1-py2.7-python.org-macosx10.3.dmg
. 从那里,我选择了Mac OS X安装程序
numpy-1.6.1-py2.7-python.org-macosx10.3.dmg
。
When I went to Idle and typed in 当我去Idle并输入时
>>> import numpy as np
This is the error I received: 这是我收到的错误:
Traceback (most recent call last):

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy/core/multiarray.so: no matching architecture in universal wrapper
I also tried it from the terminal and got the same error. 我也从终端尝试了它并得到了同样的错误。 I have a virtual environment installed - virtual env wrapper.
我安装了虚拟环境 - 虚拟环境包装器。 I called the environment in the terminal by:
我通过以下方式呼叫终端中的环境:
source my_new_env/bin/activate
And then I tried to import numpy in the terminal that way, but then I got the error: 然后我尝试在终端中导入numpy,但后来我得到了错误:
(my_new_env) $ sudo python -c 'import numpy; numpy.test()'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named numpy
I am not sure if I installed NumPy incorrectly or if my virtual environment is conflicting with Nose. 我不确定我是否错误地安装了NumPy,或者我的虚拟环境是否与Nose冲突。 If anyone has suggestions let me know!
如果有人有建议让我知道!
i would skip the MacOS package install and use the 'pip install' instructions, since you're already familiar with virtualenvs. 我会跳过MacOS包安装并使用'pip install'说明,因为你已经熟悉了virtualenvs。 use these instructions instead: http://www.scipy.org/install.html#installing-via-pip
请改用这些说明: http : //www.scipy.org/install.html#installing-via-pip
it's easier to work with a virtualenv and pip, which will ensure post-install that your virtualenv will have access to the modules you've installed. 使用virtualenv和pip更容易,这将确保您的virtualenv可以访问您已安装的模块的安装后。 it takes more work to do that with an external package (or .dmg) that you've downloaded.
使用您下载的外部包(或.dmg)需要做更多的工作。 not impossible, just more work.
不是不可能,只是更多的工作。 HTH.
HTH。
Try these commands: 试试这些命令:
brew update
, brew doctor
brew update
, brew doctor
, because, in my case, I didn't even have to install numpy
separately. ,因为,在我的情况下,我甚至不必单独安装
numpy
。 Yet I could import numpy
easily. 然而,我可以轻松导入
numpy
。 Meanwhile you can try downloading the numpy
package from this website . 同时你可以尝试从这个网站下载
numpy
包。
