Hi Sir, i am trying this code but showing this error
detecter.generate(args[1], True)
IndexError: list index out of range
out of range is showing

hii .. you have to run the file using the following command :
"python face_cropper.py [your_image_path]"
here, [your_image_path] is a string which contains the location/name of the image you want to crop, which the code takes as args[1] .. you cannot leave that blank
hey ammm. i am begining pls tell me . how to run this code in spyder now i can import every module but i can't run anything. it tell IndexError: list index out of range
For all having problems use this line from documentation and insert on line 7 (don't need to use CASCADE_PATH now; it will automatically detect the path your filesystem has):
Cascade_path is useful only the places where have you deployed the code remotely i.e Docker container, Cloud Services etc
self.face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")Documentation Reference: opencv-Pypi

This is a problem with your image, I suggest you compress the image and then run, I had the same issue and compressed the image to <500kB then it worked.
Thanks, it works.
