使用pip安装SciPy和NumPy [英] Installing SciPy and NumPy using pip

问题描述

我正在尝试在要分发的程序包中创建所需的库.它需要 SciPy 和 NumPy 库. 在开发过程中，我同时使用

I'm trying to create required libraries in a package I'm distributing. It requires both the SciPy and NumPy libraries. While developing, I installed both using

apt-get install scipy

安装了SciPy 0.9.0和NumPy 1.5.1，并且运行良好.

which installed SciPy 0.9.0 and NumPy 1.5.1, and it worked fine.

我想使用pip install做同样的事情-为了能够在我自己的程序包的setup.py中指定依赖项.

I would like to do the same using pip install - in order to be able to specify dependencies in a setup.py of my own package.

问题是，当我尝试时:

pip install 'numpy==1.5.1'

它工作正常.

但是然后

pip install 'scipy==0.9.0'

惨败，

raise self.notfounderror(self.notfounderror.__doc__)

numpy.distutils.system_info.BlasNotFoundError:

Blas (http://www.netlib.org/blas/) libraries not found.

Directories to search for the libraries can be specified in the

numpy/distutils/site.cfg file (section [blas]) or by setting

the BLAS environment variable.

我如何使它工作?

推荐答案

我假设我的回答是Linux经验；我发现要使pip install scipy顺利进行，有三个先决条件.

I am assuming Linux experience in my answer; I found that there are three prerequisites to getting pip install scipy to proceed nicely.

转到此处:安装SciPY

按照说明下载，构建和导出 BLAS 的env变量，然后LAPACK .注意不要盲目剪切'n'粘贴shell命令-您需要根据您的体系结构等选择几行，并且您需要修复/添加错误地假定为的正确目录.好吧.

Follow the instructions to download, build and export the env variable for BLAS and then LAPACK. Be careful to not just blindly cut'n'paste the shell commands - there will be a few lines you need to select depending on your architecture, etc., and you'll need to fix/add the correct directories that it incorrectly assumes as well.

您可能需要做的第三件事是 yum install numpy-f2py 或等效安装程序.

The third thing you may need is to yum install numpy-f2py or the equivalent.

是的，最后，您可能需要安装gcc-gfortran ，因为上面的库是 Fortran 源.

Oh, yes and lastly, you may need to yum install gcc-gfortran as the libraries above are Fortran source.
