转载:module 'cv2.cv2' has no attribute 'xfeatures2d'(问题已解决,亲测有效!)

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-python3.4.2.16
pip install opencv-contrib-python3.4.2.16
亲测有效!
