opencv-contrib-python的安装:Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function_python


比如,SIFT就需要用到opencv-contrib-python包中的cv2.xfeatures2d。

解决方案

安装方式可见网址:
​​​https://pypi.org/project/opencv-contrib-python/​​

  1. 卸载opencv-python
    ​​​pip uninstall opencv-python​
  2. 安装opencv-contrib-python
    ​​​pip install opencv-contrib-python==3.4.2.17​

注意第二步要指定版本,安装新版本有风险,可能有错误:​​Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function 'create'​​等。
