我正在尝试使用 models.load_model() api 加载模型，但我不断收到此错误。我尝试安装所有必要的 keras 和 tensorflow 库，但它似乎不起作用。

这是我当前的代码

import numpy as np
import matplotlib.pyplot as plt
import requests
import urllib
import os
from PIL import Image

from keras_retinanet import models
from keras_retinanet.utils.image import preprocess_image, resize_image
from keras_retinanet.utils.visualization import draw_box, draw_caption
from keras_retinanet.utils.colors import label_color

# https://github.com/fizyr/keras-retinanet/releases
# urllib.urlretrieve('https://github.com/fizyr/keras-retinanet/releases/download/0.5.1/resnet50_coco_best_v2.1.0.h5',
#     'pretrained_model.h5')
# retrieving the model
model = models.load_model('pretrained_model.h5')

class_names = [l.rstrip() for l in open('coco_categories.txt')]
print(class_name)


    Traceback (most recent call last):
