  • Hi RISHABH, Welcome to SO. As I can see your question is mostly code, can you please add some details like 'what are you trying to do?', 'what did you try?' and 'what went wrong?'. Also format the errors properly. – Aniket Tiratkar Nov 13 '20 at 13:18
  • hi Aniket, I was actually trying to implementing a image classification model using open_cv and is haar classification methods. i was just starting to use the haarcascade_frontalface_deafult.xml .While on calling it on detecting Multiscale i got an errror which probably says that file is not found. Although file is saved in the the right folder. i wonder if it's because of the wrong open_cv version or something wrong with my jupyter notebook – RISHABH JAIN Nov 15 '20 at 08:10
