與英特爾編譯器和MKL構建Numpy - CentOS 7

Question

目前，我正在嘗試在CentOS 7上使用英特爾編譯器爲英特爾MKL構建Numpy-1.9.1。我已安裝英特爾Parallel XE Studio 2015 C++和Fortran for Linux，並且我的終端我可以同時使用'icc'和'ifort'命令，它們都沒有問題。我也運行：

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

按照本指南從英特爾的網頁做正是我想要做的事：https://software.intel.com/en-us/articles/numpyscipy-with-intel-mkl，我已經試圖建立numpy的使用這個命令：

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

生成的消息是：

我使用的CentOS 7一這是我的操作系統。看起來由於某種原因，構建腳本找不到icc。

我需要使用英特爾編譯器進行numpy編譯，因爲從我收集的內容來看，我需要使用英特爾編譯器和英特爾MKL進行numpy編譯，才能自動卸載到至強皮膚。如果有人爲自動卸載到Xeon Phi而構建了numpy，或者在這個問題上使用英特爾編譯器創建numpy，我將很感激修復這個錯誤的輸入。

在Unix/Linux系統中，sudo命令（小號 UPER ù SER DO）被設置爲使用爲root用戶定義的環境變量，而不是用戶運行該命令。如果您將程序安裝在非標準位置，則需要使用超級用戶權限運行，否則可能會導致問題。例如，在OS X系統上（運行在BSD Unix上），默認情況下，環境變量中不包含/usr/local/bin。您可以設置您的用戶帳戶以將此目錄包含在您的PATH中，但如果您嘗試將sudo與該程序一起使用，則不會找到它，除非您修改root的環境（或系統環境）以包含/usr/local/bin在PATH。

這可能是您問題的原因。 icc和ifort位於（IIRC）/opt/intel/bin和/或/opt/intel/composer_xe_2015/bin（其中一個可能符號鏈接到另一個），並且您至少已將其中一個目錄添加到您的$PATH環境變量中，但在使用sudo執行構建命令，程序沒有被找到。爲了解決這個問題，不要使用sudo構建。首先，以清除任何剩餘的臨時文件，運行

sudo make clean 

然後運行

python setup.py config --compiler=intelem 

，確認一切設置正確。接下來，運行

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

建立一切。如果沒有任何錯誤成功，則可以選擇運行

python setup.py test 

（我不認爲你需要的compiler論據這一目標）來驗證構建，然後運行

sudo python setup.py install 

安裝一切在您系統的site-packages目錄中。由於site-packages歸root所有，此處需要sudo。
