2020-02-18 04:49:37 -0600 | marked best answer | I'm compiling opencv3.4.9 and contrib3.4.9. But it doesn't work with python2.7[SOLVED] I solved many problems and finally, cmake, make, sudo make install, but when I run this code: sift = cv2.xfeatures2d.SIFT_create()
AttributeError: 'module' object has no attribute 'xfeatures2d'
here is my Cmake config: cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D OPENCV_EXTRA_MODULES_PATH=/Users/lixin/Desktop/material/opencv/opencv_contrib-3.4.9/modules \ -D BUILD_EXAMPLES=ON \ -D OPENCV_ENABLE_NONFREE=ON \ -D PYTHON_INCLUDE_DIR=/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/ .. In the output of Cmake, I notice something unusual, that xfeatures2d is in both To be built list and Unavailable list but I don't know why: OpenCV modules: -- To be built: aruco bgsegm bioinspired calib3d ccalib core datasets dnn dnn_objdetect dpm face features2d flann fuzzy hfs highgui img_hash imgcodecs imgproc line_descriptor ml objdetect optflow phase_unwrapping photo plot python2 reg rgbd saliency shape stereo stitching structured_light superres surface_matching text tracking ts video videoio videostab xfeatures2d ximgproc xobjdetect xphoto -- Disabled: world -- Disabled by dependency: - -- Unavailable: cnn_3dobj cudaarithm cudabgsegm cudacodec cudafeatures2d cudafilters cudaimgproc cudalegacy cudaobjdetect cudaoptflow cudastereo cudawarping cudev cvv freetype hdf java js matlab ovis python3 sfm viz xfeatures2d -- Applications: tests perf_tests examples apps -- Documentation: NO -- Non-free algorithms: YES However, it goes well in the make and make install process, I can even find these infos: [ 78%] Built target opencv_xfeatures2d [ 78%] Built target example_xfeatures2d_surf_matcher [ 78%] Built target example_xfeatures2d_shape_transformation [ 78%] Built target example_xfeatures2d_pct_signatures [ 79%] Built target example_xfeatures2d_pct_webcam [ 80%] Built target opencv_perf_xfeatures2d [ 80%] Built target example_xfeatures2d_video_homography [ 80%] Built target example_xfeatures2d_gms_matcher [ 80%] Built target opencv_test_xfeatures2d [ 80%] Built target example_xfeatures2d_bagofwords_classification opencv_python also builds, but won't work with xfeatures2d though: [100%] Linking CXX shared module ../../lib/cv2.so [100%] Built target opencv_python2 somebody please help!!
