我已经安装了:

PYTHON_INCLUDE_DIRS=/usr/include/python2.7
PYTHON_LIBRARIES=/usr/lib/python2.7/config/libpython2.7.so
位置python.h:/usr/lib/include/python2.7/python.h
pythonlibs的位置:/usr/lib/python2.7/
如何解决这个问题？
我在我的Mac上安装了OpenCV 3.1,也安装了cv2 pip install cv2.
vinllen@ $ pip install cv2
You are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): cv2 in /usr/local/lib/python2.7/site-packages
但看起来cv2并cv不能使用:
Python 2.7.10 (default, Jul 13 2015, 12:05:58)
[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call …我知道这个问题已经在这里问了好几次,但是因为到目前为止还没有答案帮助我,所以我再次在这里发帖.
我做了什么:
我克隆了存储库https://github.com/Itseez/opencv,创建并更改为构建目录并使用以下命令编译OpenCV.
cmake -D CMAKE_BUILD_TYPE=RELEASE -D WITH_TBB=ON -D BUILD_opencv_python2=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON -D WITH_CUDA=ON -D WITH_CUBLAS=ON -D CUDA_ARCH_BIN="2.0 3.0 3.5" ..
make
sudo make install
一切都编好了.后来我加入/usr/local/lib到/etc/ld.so.conf.d/opencv.conf和执行sudo ldconfig.最后,我补充道
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
到我当地的bashrc.一切正常,我也可以执行cpp示例,但是一旦我尝试python示例或尝试在python中使用OpenCV,我得到:
ImportError:没有名为cv2的模块
我根据其他帖子尝试的事情:
手动复制cv2.so到/usr/local/lib/python2.7/dist-packages:没有用,因为我无法在任何地方找到cv2.so.
缺少numpy或numpy的多个版本:这里没问题,因为我只有一个版本的numpy.
额外:
我也尝试了与主页上最新来源相同的步骤:相同的结果.
我发现有几个资源说BUILD_NEW_PYTHON_SUPPORT现在没有正确的标志BUILD_PYTHON_SUPPORT,就像在早期版本中那样.由于两者都不适合我,我用过BUILD_opencv_python2.那是对的吗？
那么,这可能是什么问题？我的意思是,除了我的机器上没有cv2.so的事实.顺便说一句,我使用的是Ubuntu 14.04.
提前致谢.
我刚刚运行脚本来安装OpenCV.我在这里运行Linux.我经过多次努力才安装它,但它终于完成了.话虽如此,由于某种原因,它仍然无法正常工作.在我的生活中,我从来没有遇到过这么多麻烦.以下是我的终端的最后几行:

任何人都有任何想法为什么它不工作？谢谢
我正在尝试在运行apache的Amazon EC2 Micro实例上创建的python Web应用程序上使用OpenCV.
除了OpenCV没有安装外,我已经完成了所有配置和工作.这是我从Apache错误日志中获得的输出.
[Thu Aug 04 18:31:54 2016] [error] [client 72.219.147.5] import cv2
[Thu Aug 04 18:31:54 2016] [error] [client 72.219.147.5] ImportError: No module named cv2
这是我尝试过的:
我已经安装了pip并尝试了运行 pip install pyopencv
这不起作用,给我错误.
我还尝试通过以下方式手动安装它:如何在Amazon Linux上安装OpenCV？

这个:http://techieroop.com/install-opencv-in-centos/
即使在安装之后,也无法找到cv2.so文件.我尝试使用它来搜索它sudo find / -name "cv2.so"但没有出现.
但是,我.so安装了以下文件:
/usr/local/lib/libopencv_photo.so
/usr/local/lib/libopencv_stitching.so
/usr/local/lib/libopencv_flann.so
/usr/local/lib/libopencv_imgcodecs.so

此外,在运行cmake命令时,这是我得到的输出:
