如何将 Flask 中的变量部署到 html 表格中的单元格？

Question

我正在尝试将变量“预测”从 FLASK 部署到 ID = 预测的单元格中。该变量在应用程序中正确计算，我只是无法在 html 表中部署和显示它...如果您能告诉我如何继续，我将非常感激。我完成了模型中最困难的部分，但现在无法部署它。提前致谢

import numpy as np

from flask import Flask, request, render_template

import pickle

import pandas as pd

app = Flask(__name__)

model = pickle.load(open('logreg.pkl', 'rb'))

@app.route('/')

def home():

    return render_template('index.html')

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

def predict():

    int_features = [str(x) for x in request.form.values()]

    final_features = np.array(int_features)    

    

    df = pd.read_csv('list_last_update.csv') 

    home_team = df[df['Name']==final_features[0]]

    away_team = df[df['Name']==final_features[1]]

    

    X1 = np.array(home_team[['OVA', 'ATT']])

    

    X2 = np.array(away_team[['OVA', 'ATT']])

    

    X = np.concatenate((X1, X2), axis=None).astype(int)

    

    X = X.reshape(1, -1)

    

    

    prediction = model.predict(X)

   

    return render_template('index.html')

    

if __name__ == "__main__":

    app.run(host='0.0.0.0',port=8080)

<td>   

<div class="autocomplete" style="width:300px;">

<input id="away_team" type="text" name="team2" placeholder="Away Team" required="required" />

</div>

</td>

<button type="submit" class="btn btn-primary btn-block btn-large">Print team rates</button>

</form>

<td>   

<input id="prediction"  type="number" style="text-align:center"/>

</td>

<td>

<input id="draw_game_odd" type="number" style="text-align:center"/>

</td>

<td>

<input id="away_team_odd" type="number" style="text-align:center"/>

</td>

您可以将prediction变量传递给 render_tempalte 作为kwargprediction = model.predict(X) return render_template('index.html', prediction=prediction)然后在 HTML 文件中访问/插入预测。例如<div>     {{ prediction }} </div
