У меня есть программа flask, которая использует OpenCV и mediapipe. Приложение создает веб-сервер, который получает входной видеофайл, а затем обрабатывает данные на нем с помощью mediapipe.

Когда я запускаю свой код в виртуальной среде, я получаю следующую ошибку.

 Debugging middleware caught exception in streamed response at a point where response headers were already sent.

Ниже приведен HTML-код:

 header_text = '''

instructions = '''
    <p><em>Gesture Recognition</em>:</p>'''

    <form method="POST">

    '''
 

Это строка 67 с первой ошибкой:

 image_path = os.path.join(os.getcwd(),'live.jpeg')
image = detector.image    
 

И строка 226 со второй ошибкой атрибута (я импортировал mediapipe как mp):

 def detect(self,model_name,source = 0,trail_frames=[5,15]):
        if source != 0:
            self.yt_url = 'https://www.youtube.com/watch?v='
            vPafy = pafy.new(self.yt_url   source)
            play = vPafy.getbest(preftype="mp4")
            source = play.url
        cap = cv2.VideoCapture(source)
        # Initiate holistic model
        with open(model_name   '_body_language.pkl', 'rb') as f:
            model = pickle.load(f)
        self.mp_drawing = mp.solutions.drawing_utils # Drawing helpers
        self.mp_holistic = mp.solutions.holistic # Mediapipe Solutions
        frame_num = 0
        frame_list = []

 

Он работает на компьютере моего партнера, поэтому я думаю, что проблема не в коде, а в том, как я загрузил и настроил mediapipe и, возможно, OpenCV.
Спасибо!
