如何解决此错误？我正在创建一个项目并使用 flask 部署模型。但是在线上model=pickle.load("fl","rb"))我遇到了错误。

import numpy as np

from flask import Flask, request, jsonify, render_template

import pickle

app = Flask(__name__)
model = pickle.load(open('model.pkl', 'rb'))

@app.route('/')
def home():
    return render_template('index.html')

@app.route('/predict',methods=['POST'])

def predict():
   
    features = request.form.values()
    prediction = model.predict(features)

    output = prediction

    return render_template('index.html', prediction_text='News is $ {}'.format(output))


if __name__ == "__main__":
    app.run(debug=True)
