Python 为 scipy 安装 BLAS 和 LAPACK 的最简单方法是什么？

Question

提问by Marko

I would like to run a programme that someone else has prepared and it includes scipy. I have tried to install scipy with

我想运行一个别人已经准备好的程序，它包括 scipy。我试图安装 scipy

pip install scipy

but it gives me a long error. I know there are ways with Anaconda and Canopy but I think these are long ways. I would like to have a short way. I have also tried

但它给了我一个很长的错误。我知道 Anaconda 和 Canopy 有很多方法，但我认为这些方法很长。我想要一条捷径。我也试过

Why does a scipy get so complicated ?

The SciPy installation pagealready recommends several ways of installing python with SciPy already included, such as WinPython.

该SciPy的安装页面已经建议已经包含SciPy的安装Python的几种方式，如WinPython。

Another way is to use wheels(a built-package format):

另一种方法是使用轮子（内置包格式）：

pip install SomePackage-1.0-py2.py3-none-any.whl

The wheel packages you can find on: http://www.lfd.uci.edu/~gohlke/pythonlibs/

您可以在以下位置找到车轮包：http: //www.lfd.uci.edu/~gohlke/pythonlibs/

For SciPy you need:

对于 SciPy，您需要：

the NumPy wheel packages
and the SciPy wheel packages

在NumPy的轮包
和SciPy 轮包

"Why does a scipy get so complicated?

“为什么 scipy 会变得如此复杂？

It gets so complicated because Python's package management system is built to track Python package dependencies, and SciPy and other scientific tools have dependencies beyond Python. Wheelsfix part of the problem, but my experience is that tools like pip/virtualenvare just not sufficient for installing and managing a scientific Python stack.

它变得如此复杂，因为 Python 的包管理系统是为跟踪 Python 包依赖关系而构建的，而 SciPy 和其他科学工具的依赖关系超出了 Python。Wheels解决了部分问题，但我的经验是像pip/这样的工具virtualenv不足以安装和管理科学的 Python 堆栈。

If you want an easy way to get up and running with SciPy, I would highly suggest the Anaconda distribution. It will give you everything you need for scientific computing in Python.

如果您想要一种简单的方法来启动和运行 SciPy，我强烈建议您使用Anaconda 发行版。它将为您提供在 Python 中进行科学计算所需的一切。

If you want a "short way" of doing this (I'm interpreting that as "I don't want to install a huge distribution"), you might try minicondaand then run conda install scipy.

如果您想要一种“简短的方式”来执行此操作（我将其解释为“我不想安装一个巨大的发行版”），您可以尝试使用miniconda，然后运行conda install scipy.

For windows: Best is to use pre-compiled package available from this site: http://www.lfd.uci.edu/%7Egohlke/pythonlibs/#scipy

对于 Windows：最好使用以下站点提供的预编译包：http: //www.lfd.uci.edu/%7Egohlke/pythonlibs/#scipy

Using conda install scipy instead of pip solved the problem for me!

使用 conda install scipy 而不是 pip 为我解决了这个问题！

Answer 5

回答by kcrisman

For completeness, though this probably would not work well given your particular setup (external program + Windows), one can also acquire Scipy hassle-free as part of the (large) SageMathdownload.

为了完整起见，尽管鉴于您的特定设置（外部程序 + Windows），这可能不会很好地工作，但作为（大型）SageMath下载的一部分，您也可以轻松获得 Scipy 。

Either use SciPy whl, download the appropriate one and run pip install <whl_file>

要么使用SciPy whl，下载适当的一个并运行pip install <whl_file>

OR

或者

Read through SciPy Windows issue and run one of the methods.

通读SciPy Windows 问题并运行其中一种方法。

OR

或者

Use Miniconda.

使用Miniconda。

Additionally, install Visual C++ compiler for python2.7in-case it asks for it.

此外，如果需要，请为 python2.7安装Visual C++ 编译器。

For Debian Jessieand Stretchinstalling the following packages resolves the issue:

对于Debian Jessie和Stretch，安装以下软件包可解决此问题：

sudo apt-get install libblas3 liblapack3 liblapack-dev libblas-dev

Your nextissue is very likely going to be a missing Fortran compiler, resolve this by installing it like this:

您的下一个问题很可能是缺少 Fortran 编译器，请通过如下安装来解决此问题：

sudo apt-get install gfortran

If you have any issue with a missing Python.h file like this:

如果您对缺少的 Python.h 文件有任何问题，如下所示：

Python.h: No such file or directory

I got this problem on freeBSD. It seems lapack packages are missing, I solved it installing them (as root) with:

我在 freeBSD 上遇到了这个问题。似乎缺少 lapack 软件包，我解决了安装它们（以 root 身份）的问题：

pkg install lapack
pkg install atlas-devel  #not sure this is needed, but just in case

I imagine it could work on other system too using the appropriate package installer (e.g. apt-get)

我想它也可以使用适当的软件包安装程序（例如 apt-get）在其他系统上工作

Always for Ubuntu/Debian, chjortlund's answerit's very good but not perfect, since this way you get an unoptimized BLAS library. You have simply to do:

对于 Ubuntu/Debian，chjortlund 的回答总是很好，但并不完美，因为这样你会得到一个未优化的 BLAS 库。你只需要做：

sudo apt install libatlas-base-dev

and voila'!
