Win10+Anaconda3环境下的OpenCV4.0-Python安装教程
python基础教程电子书百度云在Ubuntu16.04环境下,进⼊Anaconda虚拟环境,输⼊
pip install opencv-python -i pypi.tuna.tsinghua.edu/simple/
可以直接安装OpenCV 4.0了,⼀⾏代码搞定,美滋滋。
Win10+Anaconda3环境下的OpenCV4.0-Python安装教程
在OpenCV 3.0发布三年半之后,OpenCV 4.0终于发布了。我看了⼀下⽹上的教程都是利⽤Visual Studio对OpenCV源码进⾏编译的办法来安装的,繁琐不说,还容易出错。我尝试了⼀下⽤编译好的版本结合Anaconda3进⾏OpenCV4.0安装,完美⽀持Python2.7版本,对Python3,⽬前还只能在...\site-packages\opencv\build\python这个路径下运⾏,还请各路⼤神多多指点。
创建虚拟环境
⾸先安装Anaconda3,安装步骤不再赘述,可以参考我前⾯的博客
安装完之后,打开命令⾏,输⼊以下命令,创建⼀个虚拟环境,在⾥⾯乱搞是不会破坏外⾯配置好的环境的。环境的名字可以随便取,我取的是opencv40,python版本⽤3.5就⾏。
conda create -n opencv40 python=3.5
⽤conda env list来查看已创建的所有环境,⽤activate opencv40来激活环境,输⼊conda install numpy matplotlib安装必要的package。如果安装速度慢,可以。
下载OpenCV 4.0.0-alpha
OpenCV的下载⽹址,在这⾥可以看到所有的发⾏版本。
vba inputbox输入密文最新的版本是OpenCV4.0,还有两个版本是alpha和beta。我下载了4.0.0和4.0.0-alpha两个版本。
点击4.0.0-alpha,选择红框的⽂件下载。
如果连接不稳定,可以⽤我的百度云链接。
4.0.0
4.0.0-alpha
integer占几个字节下载完之后,双击打开exe⽂件,将其解压到D:\Program Files\Anaconda3\envs\OpenCV40\Lib\site-packages,这是我的Anaconda3的虚拟环境opencv40下的Python的package存放路径。
如果你之前解压的是4.0.0-alpha,则进⼊...\site-packages\opencv\python\2.7\x64,将cv2.pyd复制到...\Anaconda3\envs\OpenCV40\Lib\site-packages中。
在命令⾏(环境激活状态下)进⼊python,如下图可见安装成功。
如果你之前解压的是4.0.0,则命令⾏进⼊...\site-packages\opencv\python\,执⾏python setup.py install,如下图。
然后不知为何报错了
