Installing SciPy on Ubuntu
提问by Hyman Gibson
I have Python 2.7 running and trying to install scipy by using easy_install which returns following errors:
我运行 Python 2.7 并尝试使用返回以下错误的 easy_install 安装 scipy：
Searching for scipy
Reading http://pypi.python.org/simple/scipy/
Reading http://www.scipy.org
Reading http://sourceforge.net/project/showfiles.php?group_id=27747&package_id=19531
Reading http://new.scipy.org/Wiki/Download
Best match: scipy 0.11.0
Downloading http://pypi.python.org/packages/source/s/scipy/scipy-0.11.0.zip#md5=40b700ddde9ddab643b640fff7a9d753

So I installed Blas and Atalas by executing

apt-get install blas
apt-get install atlas
However, the easy_install errors don't disappear.
但是，easy_install 错误不会消失。
Thanks!
谢谢！

Ubuntu puts library files in a rather exotic directory.
/usr/lib/x86_64-linux-gnu/or something, depending on your architecture.
You need to add this directory to the site.cfg file or the BLAS environment variable.
Ubuntu 将库文件放在一个相当奇特的目录中。
/usr/lib/x86_64-linux-gnu/或其他什么，取决于您的架构。您需要将此目录添加到 site.cfg 文件或 BLAS 环境变量中。
If easy install also needs the header files, you need to install the respective -dev packages.
如果easy install 还需要头文件，则需要安装相应的-dev 包。
But, like @pitsanu-swangpheaw suggests, you can also install to the site packages directory using the ubuntu package manager.
但是，就像@pitsanu-swangpheaw 建议的那样，您也可以使用 ubuntu 包管理器安装到站点包目录。
sudo apt-get install python-numpy python-scipy

I solved the issue by running (similar to previous suggestions)
我通过运行解决了这个问题（类似于以前的建议）
apt-get install scipy

sudo apt-get install python-scipyworked in my case.
sudo apt-get install python-scipy在我的情况下工作。

What worked for me:
什么对我有用：
To actually install scipy from PIP, you need packages libatlas-base-dev(libraries etc. for ATLAS/BLAS) and gfortran(GNU Fortran compiler).
要从 PIP 实际安装 scipy，您需要软件包libatlas-base-dev（ATLAS/BLAS 的库等）和gfortran（GNU Fortran 编译器）。
Once these packages are installed, the scipy installer should finish as expected.
安装这些软件包后，scipy 安装程序应该会按预期完成。

If you are using Python3, You can install packages using apt-get
如果您使用的是 Python3，您可以使用安装包 apt-get
sudo apt-get install python3-numpy python3-scipy
回答by Sam Whitlock
If you want to still install using pip, you can use build-dep to get the dependencies of python-numpy and python-scipy, and then install using pip
如果还想安装 using pip，可以使用 build-dep 获取 python-numpy 和 python-scipy 的依赖，然后安装 usingpip
sudo apt-get build-dep python-numpy python-scipy
Substitute for python3 as the other answers state of that's what you're looking for.
替代 python3 作为其他答案状态，这就是您正在寻找的内容。
