我有步骤在回购，将帮助您正确安装OpenCV。

如果链接断了，看这个。

对于要求和先决条件，请遵循以下说明:

你需要有WINDOWS操作系统来开始这个项目。

Windows 7到10

请仔细执行以下步骤

Install Anaconda2 32/64 python 2 or Install Anaconda3 32/64 python 3 It Depends on System Information Along the way you must check all the options ignore the red text Then wait till installation completed ... Open CMD admin when finish installed Make sure that the anaconda-python is configured in CMD admin Type: python This will come out: C:\WINDOWS\system32>python Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. Next is to install packages: Numpy OpenCV PyMySQL or pymysql Install and Import OpenCV conda install -c conda-forge opencv = (version optional) (click yes if there's updates) Install and Import Numpy pip install numpy (click yes if there's updates) Install and Import PyMySQL/pymysql pip install PyMySQL or pymysql When all the package is completely installed, then you must Reboot it. go to CMD admin again type "python" import cv2 (cv2 is OpenCV) import Numpy or numpy import pymysql import os from PIL from Image if all of then is ok.. your ready to run the code!! After you finish all the steps, you can now test the code in SPYDER python that I use

下面的命令为opencv3添加了一个不同的anaconda通道，您应该能够从中提取。

conda install --channel  https://mirrors.ustc.edu.cn/anaconda/cloud/menpo opencv3

Windows 7, conda 4.4.10 python 2.7.6 从非官方的Windows二进制文件下载了opencv包用于python扩展包。(选择python 2.4 AMD 64) 光盘下载 PIP install opencv_python Python run_some.py (import cv2…)似乎可以工作。 YMMV

下面是使用conda安装适用于Python的包的一般方法:

conda search packageName e.g. conda search opencv If this doesn't return results, conda install packageName will not work. At this point you can go to, https://anaconda.org/ and type the packageName into the search box. If this pulls up results (which it should for OpenCV), then click on one of the results that is for your platform (e.g. win-64). The next page will show you the command to use to install this package (e.g. conda install -c menpo opencv=2.4.11). If your package doesn't return results by search https://anaconda.org, then you can try pip install packageName.

注意:当我使用步骤3为win-64安装OpenCV时，当我试图导入cv2时，我得到了一个错误。

错误如下:

RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

ImportError: numpy.core.multiarray导入失败

我认为这个错误是由于软件包版本冲突。尽管如此，这是安装OpenCV和其他Python包的有效方法，只是可能需要解决一些包的版本冲突。

在Linux上，正如这里所讨论的，目前获得opencv的最佳方法是在conda-forge的loopbio:

conda install -c loopbio -c conda-forge -c pkgw-forge ffmpeg-feature ffmpeg gtk2 opencv

如果你有一个“现代CPU”，也会有一个编译版本“支持所有现代CPU指令集扩展[…]]和反对libjpeg-turbo":

conda install -c loopbio -c conda-forge -c pkgw-forge ffmpeg-feature ffmpeg gtk2 opencv-turbo`

其他答案中提到的两个解决方案并不无条件有效:

The conda you get through conda install opencv or pip install opencv-python doesn't have gtk2 support, so you can't display images through imshow. Conda built by Menpo (conda install -c menpo opencv3) has gtk2 support, but they have only built OpenCV 3.2 for Python 3.5, not Python 3.6 Ubuntu 16.10 has deprecated libpng12, leading to a missing dependency and the following error when trying to import cv2: ImportError: libpng12.so.0: cannot open shared object file: No such file or directory, as discussed here

编辑:@Yamaneko指出，截至2017年6月14日，“loopbio的OpenCV 3.2.0版本存在一个问题。无声地读写视频失败。这是由于上游OpenCV问题与旧GCC的结合。详情请点击这里。有一个公关正在解决这个问题。”

在Anaconda窗口中安装当前版本OpenCV 3.3的正确命令:

conda install -c conda-forge opencv

or

conda install -c conda-forge/label/broken opencv

3.2使用这个:

conda install -c menpo opencv3
