在Ubuntu上安装SciPy

Question

我运行Python 2.7并尝试使用easy_install安装scipy,它返回以下错误:

所以我通过执行安装了Blas和Atalas

apt-get install blas
apt-get install atlas

但是,easy_install错误不会消失.

谢谢!

Answer 1

什么对我有用:

要从PIP实际安装scipy,您需要包libatlas-base-dev(ATLAS/BLAS的库等)和gfortran(GNU Fortran编译器).

安装这些软件包后,scipy安装程序应按预期完成.

Answer 2

Ubuntu将库文件放在一个相当奇特的目录中. /usr/lib/x86_64-linux-gnu/什么的,取决于你的架构.您需要将此目录添加到site.cfg文件或BLAS环境变量中.

如果简易安装也需要头文件,则需要安装相应的-dev软件包.

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

Answer 3

sudo apt-get install python-scipy在我的案例中起作用。

Answer 4

如果您使用的是Python3,则可以使用安装包 apt-get

sudo apt-get install python3-numpy python3-scipy
