現在、CentOS 7 で Intel コンパイラを使用して Intel の MKL 用の Numpy-1.9.1 をビルドしようとしています。Intel Parallel XE Studio 2015 C++ と Linux 用の Fortran がインストールされており、端末では「icc」と「ifort」の両方を使用できます。コマンドを実行すると、どちらも問題なく検出されます。私も実行しました：
$ source /opt/intel/composer_xe_2015/bin/compilervars.sh intel64
私がやろうとしていることを正確に行うためのIntelのWebページのこのガイドに従って: https://software.intel.com/en-us/articles/numpyscipy-with-intel-mkl、これを使用してnumpyを構築しようとしました指図：
$ sudo python setup.py config --compiler=intelem build_clib --compiler=intelem build_ext --compiler=intelem install
結果のメッセージは次のとおりです。
Running from numpy source directory.

このためのオペレーティング システムとして CentOS 7 を使用しています。何らかの理由で、ビルド スクリプトが icc を見つけられないようです。
私が収集したものから、Xeon Phi への自動オフロードを利用できるようにするには、Intel コンパイラーと Intel MKL で numpy ビルドが必要なので、Intel コンパイラーで numpy ビルドが必要です。誰かが Xeon Phi への自動オフロード用に numpy をビルドした場合、またはこの問題で Intel コンパイラで numpy をビルドした場合は、このエラーを修正するための情報をいただければ幸いです。
