Question

目前我正在尝试使用CentOS 7上的英特尔编译器为英特尔MKL构建Numpy-1.9.1。我安装了Intel Parallel XE Studio 2015 C ++和Fortran for Linux，在我的终端中我可以同时使用'icc'和'ifort'命令，它们都没有问题。我也跑了：

$ source /opt/intel/composer_xe_2015/bin/compilervars.sh intel64

根据英特尔网页上的指南，我正在尝试做的事情：https://software.intel.com/en-us/articles/numpyscipy-with-intel-mkl，我尝试使用此命令构建numpy：

$ sudo python setup.py config --compiler=intelem build_clib --compiler=intelem build_ext --compiler=intelem install

结果信息是：

我使用CentOS 7作为我的操作系统。看来由于某种原因，构建脚本找不到icc。

我需要使用英特尔编译器进行numpy构建，因为从我收集到的内容来看，我需要使用英特尔编译器和英特尔MKL进行numpy构建，以便自动卸载到Xeon Phi。如果有人为自动卸载到Xeon Phi构建了numpy，或者只是在这个问题上使用英特尔编译器构建了numpy，我将非常感谢修复此错误的输入。

在Unix / Linux系统上，sudo命令（ S uper U ser DO ）设置为使用为root用户定义的环境变量，而不是运行该命令的用户。如果您在非标准位置安装程序，则需要以超级用户权限运行该程序，这可能会导致问题。例如，在OS X系统上（运行在BSD Unix上），/usr/local/bin环境变量中默认不包含PATH。您可以设置用户的帐户以在PATH中包含此目录，但如果您尝试将sudo用于其中的程序，则无法找到该目录，除非您修改root要在/usr/local/bin中加入PATH的环境（或系统环境）。

这可能是您的问题的原因。 icc和ifort位于/opt/intel/bin和/或/opt/intel/composer_xe_2015/bin中的（IIRC）（其中一个可以与另一个进行符号链接），并且您已添加了至少一个您的$PATH环境变量的目录，但使用sudo执行构建命令时，找不到程序。要解决此问题，请不要使用sudo进行构建。首先，要清除任何剩余的临时文件，请运行

sudo make clean

然后运行

python setup.py config --compiler=intelem

并确认所有设置正确。接下来，运行

python setup.py build_clib --compiler=intelem build_ext --compiler=intelem

构建一切。如果成功没有错误，可选择运行

python setup.py test

（我认为您不需要此目标的compiler参数）来验证构建，然后运行

sudo python setup.py install

在系统的site-packages目录中安装所有内容。此处需要sudo，因为site-packages拥有root。
