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 I solve this error?

Hi@akhtar,

This looks as if you don't load the classifier successfully from the file. Make sure you have harrcasecade file in your folder and read that file first and then try to train your model.

Hope this will work.
