无法在python中加载facenet_keras.h5模型

Question

我是tensorflow的新手，不知道出了什么问题。它让我不断地展示这个“糟糕的马歇尔错误”，我似乎无法理解它是由什么引起的。 版本： python:3.8 tensorflow:2.5.0 keras:2.4.3

下面是我的代码

import os
import tensorflow as tf
from tensorflow.keras import layers
from keras.models import load_model
from tensorflow.keras.models import Model
from tensorflow.python.keras.backend import set_session 
from flask import Flask, request
from flask_cors import CORS
import cv2
import json
import numpy as np
import base64
from datetime import datetime

database = {}
graph = tf.compat.v1.get_default_graph()
app = Flask(__name__)
CORS(app)
sess = tf.compat.v1.Session()
set_session(sess)


#loading model
model = load_model('facenet_keras.h5')
model.summary()

下面是我遇到的错误：
