I am running opencv via python on the Raspberry Pi and am getting the following error.

blobd = cv2.SimpleBlobDetector() AttributeError: 'module' object has no attribute 'SimpleBlobDetector'

my code is blobd = cv2.SimpleBlobDetector()

I have also tried to create the cv2.SimpleBlobDetector_Params() with the same issue.

As noone else seems to have had this problem I'm a bit baffled.

Same problem here. Did the syntax change from all the examples? I find it strange that the line params = cv2.SimpleBlobDetector_Params() does not cause an error. In my case, the error is only with detector = cv2.SimpleBlobDetector(params) I have cv2.__version__ '3.0.0' running on Windows 7.

SOLVED Ok, syntax changed to SimpleBlobDetector_create() without notice. With my 3.0.0 version, this works:

detector = cv2.SimpleBlobDetector_create(params)
