无法读取文件字符串文件"/opt/intel/mkl/include/mkl_version.h“

Question

对于Python3.4.3、Ubuntu14.04、CUDA8和最新版本的OpenCV，请从opencv网站下载，并使用以下命令：

(cv2) mona@pascal:~/computer_vision/opencv-3.2.0/build$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

我得到以下错误。请建议修复方法。

Answer 1

安装最新版本的英特尔MKL即可解决此问题。我的机器上有一个更老的版本。基本上，只需下载l_mkl_2017.0.098.tgz并键入sudo ./install.sh，然后按照对话框中的正确选择进行操作。这是一个简单的安装。

在使用cmake成功之后，您应该会得到一个类似于以下内容的报告：

Answer 2

在Ubuntu12.04机器上，我下载的最新的MKL版本(l_mkl_2017.3.196)需要Ubuntu14.04，所以Mona的解决方案在这种情况下不起作用。

对我来说起作用的是在第71行之后添加一个if到opencv-3.2.0/cmake/OpenCVFindMKL.cmake：

set(MKL_INCLUDE_DIRS ${MKL_ROOT_DIR}/include)
if(NOT EXISTS "${MKL_INCLUDE_DIRS}/mkl_version.h")   # added these 3 lines
    mkl_fail()                                       #
endif()                                              #
get_mkl_version(${MKL_INCLUDE_DIRS}/mkl_version.h)

这是"official" fix for the issue的简化版本。
