Hi,

I am following the tutorial here https://www.learnopencv.com/blob-dete... and

from this line keypoints = detector.detect(im)

I get the following error

in <module> keypoints = detector.detect(back2im) SystemError: error return without exception set

Any ideas as to how to get past this?

best
