TypeError: Expected Ptr

I am making a real-time facial recognizer and the function I have to train the model is giving me an error and I have looked everywhere for a fix but none have worked. Ant help is much appreciated. The error is on the 5th to last line. see error message under the code

CODE:

 def train_model():      name_gotten3 = name_box.get()      people = [f'{name_gotten3}']      DIR = r'C:/OCV/real-time-FR/pictures'        haar_cascade = cv.CascadeClassifier('haar_face.xml')        features = []      labels = []        def create_train():          for person in people:              path = os.path.join(DIR, person)              label = people.index(person)                for img in os.listdir(path):                  img_path = os.path.join(path,img)                    img_array = cv.imread(img_path)                  gray = cv.cvtColor(img_array, cv.COLOR_BGR2GRAY)                    faces_rect = haar_cascade.detectMultiScale(gray, scaleFactor=1.1, minNeighbors=12)                    for (x,y,w,h) in faces_rect:                      faces_roi = gray[y:y+h, x:x+w]                      features.append(faces_roi)                      labels.append(label)        create_train()        features = np.array(features, dtype='object')      labels = np.array(labels)        face_recognizer = cv.face.LBPHFaceRecognizer_create()        # training on features and labels list      face_recognizer.train(features, labels)        face_recognizer.write('face-trainedreal.yml')        np.save('featuresreal.npy', features)        np.save('labelsreal.npy', labels)        print('Done training the model') ```    ERROR:    File "C:\OCV\real-time-FR\testforrealtimefd.py", line 81, in train_model      face_recognizer.train(features, labels)  TypeError: Expected Ptr<cv::UMat> for argument 'src'
