你可以查看官方文档或搜索相关的社区讨论,看看是否有其他开发者遇到了类似的问题,并分享了解决方案。 使用预编译的wheel:如果以上方法都无法解决问题,你可以尝试从PyPI下载预编译的opencv-python wheel,而不是尝试自己构建。你可以使用pip install opencv-python-headless命令来安装预编译的wheel
二、安装whl三、注意事项 问题描述在给树莓派安装opencv的时候,通过GitHub下载的文件不能解压,且如果网络不好,容易断流,此时,我选择下载whl,通过Windows传给树莓派,具体方法见link提示:以下是本篇文章正文内容,下面案例可供参考一、whl是什么?wheel文件的格式是.whl,...
安装: wheel 包 (wheel 包是一种类似于zip 格式的文件,此次安装wheel 模块,是为了后面安装opencv-python4.4.0.whl 做准备) 在cmd 的Python 安装路径Scripts下输入 pip install wheel 即可,按回车键,会自动安装。 安装好后会提示你安装成功。第三步: 安装numpy 包 (numpy 包是一种科学计算的包,里面有很多包含...
OpenCV 3.2 + contrib 在Python下可以通过直接导入wheel包来安装opencv+contrib,可以从下面这个网址下载对应的文件: opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl http://www.lfd.uci.edu/~gohlke/pythonlibs/ KNN KNN算法,即K-nearest neigbours - based Background/Foreground Segmentation A...
