Question

def load_file():
  # Проходим циклом и загружаем все файлы из папок
  cat_files = []
  dog_files = []

  for i in (cat_name):
    df = cv2.VideoCapture(file_name_cat + i)
    frameCount = int(df.get(cv2.CAP_PROP_FRAME_COUNT))
    frameWidth = int(df.get(cv2.CAP_PROP_FRAME_WIDTH))
    frameHeight = int(df.get(cv2.CAP_PROP_FRAME_HEIGHT))
    cat = np.empty((frameCount, frameHeight, frameWidth, 3), np.dtype('uint8'))
    fc = 0
    ret = True
    while (fc < frameCount  and ret): # The error is given here
      ret, cat[fc] = df.read()
      fc += 1
    cat_files.append(cat)
    
  for i in (dog_name):
    df = cv2.VideoCapture(file_name_dog + i)
    frameCount = int(df.get(cv2.CAP_PROP_FRAME_COUNT))
    frameWidth = int(df.get(cv2.CAP_PROP_FRAME_WIDTH))
    frameHeight = int(df.get(cv2.CAP_PROP_FRAME_HEIGHT))
    dog = np.empty((frameCount, frameHeight, frameWidth, 3), np.dtype('uint8'))
    fc = 0
    ret = True
    while (fc < frameCount  and ret):
      ret, dog[fc] = df.read()
      fc += 1
    dog_files.append(dog)

  # Применяем функцию обработки для получения стройного массива
  cat_np = min_obs(cat_files)
  dog_np = min_obs(dog_files)

  # Возвращаем полученные массивы
  return cat_np, dog_np

帮我看看是什么问题？我还不是很有经验，出现了很多问题。大约 5 个小时，我试图在互联网上找到解决方案。当我单独运行它时，一切正常

错误文本本身：

TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType' 有什么问题？
