Я пытался использовать recognizer.train(x_train, y_labels)
вместо recognizer.train(x_train, np.array(y_labels))
, но все равно получаю ошибку?

current_id += 1

faces = face_cascade.detectMultiScale(image_array, scaleFactor=1.5, minNeighbors=5)
for (x,y,w,h) in faces:
roi = image_array[y:y+h, x:x+w]

recognizer.train(x_train, np.array(y_labels))# train the data
recognizer.save("recognizers/face-trainner.yml") # Save train file
