drawKeypoints bug?
Hi! I'm trying to learn some Opencv with Python, and I'm following illustrations/examples from a book, and I'm stuck because of what seems to be a bug.
It says " AttributeError: module 'cv2.cv2' has no attribute 'drawKeypoints' "
I'm using native Python 3.6.6 on windows 7, 64bit.
I installed Opencv3 with pip.
The OpenCv version I'm using is 4.0.0.
The book I'm trying to learn from is called OpenCV 3x with Python By Example Second Edition. And it's written by Gabriel Garrido.
I've reinstalled OpenCv, without success...I also tried some suggestion about installing Opencv-contrib module (or something like that), and it didn't do any differences or whatsoever.
I've also attached a link with a picture of the code that gives me the error, so I hope the picture is available by the time this post is accepted by a mod! ^^
So is this a bug or something like that in OpenCv, or is cv2.drawKeypoints(input_image, keypoints, input_image, color=(0,255,0)) this just an incorrect use of the drawKeypoints function?
print(cv2.getBuildInformation()) :

And thanks again LBerger, for helping me with this, and also making me realize I didn't had to make a new comment all the time! :P
