It always give me the 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' Even when I take the full path, it still doesnt work: cl...
The above code demonstrates the use of np.empty() function in NumPy to create empty arrays of different sizes and data types. The np.empty() function creates an array without initializing its values, which means that the values of the array are undefined and may vary each time the function...
