【问题描述】：
目前我正在尝试使用 CentOS 7 上的英特尔编译器为英特尔的 MKL 构建 Numpy-1.9.1。我安装了英特尔 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，它们都被发现没有问题。我也跑过：
$ source /opt/intel/composer_xe_2015/bin/compilervars.sh intel64
根据英特尔网页上的本指南，我正在尝试做我想做的事情：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
得到的消息是：
Running from numpy source directory.

为此，我使用 CentOS 7 作为我的操作系统。似乎由于某种原因，构建脚本找不到 icc。
我需要使用英特尔编译器进行 numpy 构建，因为根据我收集到的信息，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，我将不胜感激有关修复此错误的意见。
【问题讨论】：
-
尝试只运行构建命令而不使用
sudo（首先运行sudo make clean进行清理）。sudo命令可能正在使用root的$PATH而不是您自己的。如果是这种情况，将不会搜索/opt/intel/bin（或/opt/intel/composer_xe_2015/bin），从而导致icc出现command not found错误。 -
@MattDMo 哇，这只是我从未怀疑过的另一件事，它是 linux 的新手。事实证明这正是问题所在。英特尔指南假定了 root 访问权限，因此如果我在 root 中设置，该命令将正常工作。相反，我运行了没有
sudo的构建命令，然后运行了python setup.py install和sudo，一切正常。我的 Numpy 现在可以完美地与我的至强 phi 配合使用。非常感谢！
