那些遇到过的问题

为scipy安装BLAS和LAPACK的最简单方法是什么？

Mar*_*rko 36 python numpy

我想运行一个别人准备的程序,它包括scipy.我曾尝试安装scipy

pip install scipy

但它给了我一个很长的错误.我知道Anaconda和Canopy有各种各样的方法,但我认为这些方法很长.我想要一个简短的方法.我也试过了

为什么scipy变得如此复杂？

ago*_*old 31

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.

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
Run Code Online (Sandbox Code Playgroud)

您可以在以下网址找到轮组:http://www.lfd.uci.edu/~gohlke/pythonlibs/

对于SciPy,您需要:

  • 嘿伙计们,谢谢你,感谢上帝为miniconda.它的工作就像一个奇迹.安装并运行`conda install scipy`,就像你建议的@jakedvp一样.现在我的程序正在运行,我很高兴.祝你今天愉快 :) (6认同)

"为什么scipy变得如此复杂？

它变得如此复杂,因为Python的包管理系统是为跟踪Python包依赖而构建的,而SciPy和其他科学工具都具有Python以外的依赖关系.轮子修复了部分问题,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.

如果你想要一个简单的方法来启动和运行SciPy,我强烈建议使用Anaconda发行版.它将为您提供Python中科学计算所需的一切.

如果你想要这样做的"简短方法"(我将其解释为"我不想安装一个巨大的发行版"),你可以试试miniconda然后运行conda install scipy.

对于Debian Jessie和Stretch,安装以下软件包可以解决问题:

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

您的下一个问题很可能是缺少Fortran编译器,通过安装它来解决这个问题:

如果您对丢失的Python.h文件有任何问题,请执行以下操作:

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

瞧！
