I am trying to initialize my Cascade classifier with cascade = cv2.CascadeClassifier(xml_path)
But it raises the error
OpenCV Error: Unknown error code -49 (Input file is empty) in cvOpenFileStorage, file C:\projects\opencv-python\opencv\modules\core\src\persistence.cpp, line 4484
cv2.error: C:\projects\opencv-python\opencv\modules\core\src\persistence.cpp:4484: error: (-49) Input file is empty in function cvOpenFileStorage
I have just downloaded the xml file from https://github.com/opencv/opencv/tree/master/data/haarcascades
What am I missing?
