python - OpenCV tutorial - Error: Unsupported format or combination of formats -


i'm trying run opencv tutorial python , opencv 2.4 gives me following error :

opencv error: unsupported format or combination of formats (both matrices must floating-point (single or double precision)) in cvconvertpointshomogeneous, file ........\opencv\modules\calib3d\src\fundam.cpp, line 901

how can address error?

i solved problem using opencv 3.0.0 rc-1 instead of 2.4

sift = cv2.sift() has replaced sift = cv2.xfeatures2d.sift_create() compatibility version.
