This is a Cv2 error regarding the Cascase Classifier

Swarad · March 29, 2020, 7:19pm

I’m getting the following error:

cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\objdetect\src\cascadedetect.cpp:1689: error: (-215:Assertion failed) !empty() in function ‘cv::CascadeClassifier::detectMultiScale’

How can this be solved?

Hey @Swarad, make sure you have haarcascade file present in the same folder as in .py file. If it is not there you can download it from here,
