不支持在图形模式下调用"myModel.predict"

Question

在开发图像识别网站时遇到了一些问题

这是代码

from flask import render_template
from flask import Flask, flash, request, redirect, url_for
from werkzeug.utils import secure_filename
import numpy as np
from tensorflow.keras.preprocessing import image
from tensorflow.keras.models import load_model
from keras.backend import set_session
import tensorflow as tf
app = Flask(__name__)
def load_model_from_file():
mySession = tf.compat.v1.Session()
set_session(mySession)
myModel = load_model('saved_model.h5')
myGraph = tf.compat.v1.get_default_graph()
return (mySession, myModel, myGraph)

我刚刚展示了它只显示错误的部分。希望能够理解

@app.route('/uploads/<filename>')
def uploaded_file(filename):
test_image = image.load_img(UPLOAD_FOLDER+"/"+filename, target_size =(150,150))
test_image = image.img_to_array(test_image)
test_image = np.expand_dims(test_image, axis=0)
mySession = app.config['SESSION']
myModel = app.config['MODEL']
myGraph = app.config['GRAPH']
with myGraph.as_default():
set_session(mySession)
result = myModel.predict(test_image)
image_src = "/"+UPLOAD_FOLDER +"/"+filename
if result[0] < 0.5 :
answer = "<div class='col text-center'><img width='150' height='150' src='"+image_src+"' class='img-thumbnail' /><h4>guess:"+x+" "+str(result[0])+"</h4></div><div class='col'></div><div class='w-100'></div>"     
else:
answer = "<div class='col'></div><div class='col text-center'><img width='150' height='150' src='"+image_src+"' class='img-thumbnail' /><h4>guess:"+y+" "+str(result[0])+"</h4></div><div class='w-100'></div>"     
results.append(answer)
return render_template('index.html',myX=x,myY=y,mySampleX=samplex,mySampleY=sampley,len=len(results),results=results)

def main():
(mySession, myModel, myGraph) = load_model_from_file()

app.config['SECRET_KEY'] = 'super secret key'
app.config['SESSION'] = mySession
app.config['MODEL'] = myModel
app.config['GRAPH'] = myGraph

app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
app.config['MAX_CONTENT_LENGTH'] = 16 * 1024 * 1024
app.run()

results = []
main()

知道我的错在哪里吗？当我在tensorflow网站上搜索时，我也不太明白。我使用的版本是2.5.0提前感谢的帮助

ValueError:不支持在图形模式下调用Model.predict当CCD_ 2实例是在启用渴望模式的情况下构造的。启用渴望模式的Please construct your Model instance in graph mode or call Model.predict。

错误显示加载模型图模式并调用model.prpredict函数。

在图中加载您的模型，如下所示：

with graph.as_default():
#Load your model
#call model.predict
Model.predict()
return
