我试图通过Anaconda为Python安装OpenCV,但我似乎无法解决这个问题。
我试着
conda install opencv
conda install cv2
我也试着搜索
conda search cv
没有雪茄。我无意中看到这个列出了opencv作为一个包含包:
http://docs.continuum.io/anaconda/pkgs.html
在运行conda info后,我注意到我的版本是3.4.1,但我似乎在网上找不到任何关于这个版本的信息。我对此很困惑。
我是不是遗漏了一些很明显的东西?如果opencv可用于Anaconda的以前版本,那么为什么它不能用于新版本呢?为什么这个链接只显示版本1.9.2的文档?
你链接的页面好像不再包含opencv了。(有趣的是,我确实记得它在之前也被包括在内。)
在任何情况下,安装OpenCV到Anaconda,虽然无法通过conda,是相当微不足道的。你只需要下载一个文件。
Download OpenCV from https://opencv.org/releases/ and extract
From the extracted folder, copy the file from the extracted directory: opencv/build/python/2.7/(either x86 or x64, depending on your Anaconda version)/cv2.pyd to your Anaconda site-packages directory, e.g., C:\Anaconda\Lib\site-packages
To get FFmpeg within opencv to work, you'll have to add the directory that FFmpeg is located in to the path (e.g., opencv/sources/3rdparty/ffmpeg). Then you'll have to find the DLL file in that folder (e.g., opencv_ffmpeg_64.dll) and copy or rename it to a filename that includes the opencv version you are installing, (e.g., opencv_ffmpeg249_64) for 2.4.9.
现在在Python提示符下,你应该可以输入“import cv2”…要验证它是否有效,输入“print cv2”。__version__”,它应该打印出你下载的OpenCV版本。
如果conda install opencv或conda install -c https://conda.binstar.org/menpo opencv不工作,您可以尝试从源代码编译。
从http://opencv.org/downloads.html下载源代码,按照http://docs.opencv.org/2.4/doc/tutorials/introduction/linux_install/linux_install.html的安装说明,(也许你可以直接跳到最后一部分,'从源代码使用CMake构建OpenCV…),修改CMake命令如下:
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/**/env/opencv-2.4.10 -D BUILD_NEW_PYTHON_SUPPORT=ON -D PYTHON_EXECUTABLE=/home/**/env/anaconda/bin/python -D PYTHON_INCLUDE_DIR=/home/**/env/anaconda/include/python2.7 -D PYTHON_LIBRARY=/home/**/env/anaconda/lib/libpython2.7.so -D PYTHON_PACKAGES_PATH=/home/**/env/anaconda/lib/python2.7/site-packages -D PYTHON_NUMPY_INCLUDE_DIRS=/home/**/env/anaconda/lib/python2.7/site-packages/numpy/core/include ..
make -j4
make install
你会得到cv2。所以在anaconda/lib/python2.7/site-packages中。
然后:
import cv2
print cv2.__version__
它将输出2.4.10。
我的环境是GCC 4.4.6, Python 2.7 (anaconda)和opencv-2.4.10。
