 <p>To actually run your flask app in debug mode, you run this command:</p> <p><code>python /home/vagrant/PythonVision/app.py</code></p> <p>Then you can go on your browser: <a href="http://ip:5000/">http://ip:5000/</a>.</p> <p>Since I know you're running this on vagrant, the <code>ip</code> might be defined by your configs, but that's beyond the scope of this question.</p>
