Print Tensorflow version

 Hi 

Try this

import tensorflow as tf print(tf.__version__) import keras print(keras.__version__)

How Flask file shows templates and images

 Hi

Normal Flask code look like

--------------

from flask import Flask, redirect, url_for, request

app = Flask(__name__)

 

 

@app.route('/success/<name>')

def success(name):

    return 'Hi %s' % name

 

 

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

def login():

    if request.method == 'POST':

        user = request.form['name']

        return redirect(url_for('success', name=user))

    else:

        user = request.args.get('name')

        return redirect(url_for('success', name=user))

 

 

if __name__ == '__main__':

    app.run(debug=True)

--------------

If you need template page, your flask file should return the following code

return render_template('template.html', result=hupresult)

Your template.html should be saved inside templates folder

and the code template.html should look like

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>Flask Image Example</title>

</head>

<body>

    <h1>{{ result }}</h1>

    <!-- Display the image from the static folder -->

    <img src="{{ url_for('static', filename='bg.jpg') }}" alt="Your Image">

</body>

</html>

The image bg.jpg should be saved inside 'static' folder
