'label' is two value-> (1, 0.0)

first value is subjects label text count ,
second is.. I don't know.

so I change like this -> label_text = subjects[label[0]]

it's work.

[informramiz]

Latest versions of OpenCV's predict function returns a (label, confidence) tuple. The first value is the label of the subject identified and the second value is the confidence score for that subject. You can use the confidence to filter out low confidence images as unknown subjects. So @Clanatia is right

changing following

label_text = subjects[label]

to

label_text = subjects[label[0]]

should work fine on OpenCV versions which give this error.

Use this instead:
face_recognizer = cv2.face.LBPHFaceRecognizer_create()

Try to install opencv using: python -m pip install --user opencv-contrib-python
And then try cv2.face.HBPHFaceRecognizer_create()
