第一种方式 : 使用镜像源
- pip install -i https://mirrors.aliyun.com/pypi/simple/ opencv-python==3.4.2.16
- pip install -i https://mirrors.aliyun.com/pypi/simple/ opencv-contrib-python==3.4.2.16
第二种方式 : Python 3.7 安装各个版本的 openCV几个方法
- 遇到该问题时,网友多是建议补个包,即
- pip install opencv-contrib-python
- 我在补完之后又出现下面这样的错误:
- OpenCV(3.4.3) C:\projects\opencv-python\opencv_contrib\modules\xfeatures2d\src\sift.cpp:1207: error: (-213:The function/feature is not implemented) This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function ‘cv::xfeatures2d::SIFT::create’
- 貌似是该算法被申请了专利还是咋的,将opencv版本退到3.4.2即可解决,卸载之前的包,然后
- pip install opencv-python==3.4.2.16
- pip install opencv-contrib-python==3.4.2.16
- 亲测有效
