我无法从我的代码中找到错误，花了我几个小时试图解决它但仍然无法使其工作。
我已经在浏览器控制台上查看了它，并在下面显示为ascreenshot： enter image description here
这是我的代码：

<?php  
session_start();

use Phpml\Classification\SVC;
use Phpml\SupportVectorMachine\Kernel;

include "koneksi.php";
include "function.php";

if(!isset($_SESSION['username'])){
    header('location:login.php');
}else{
    $username = $_SESSION['username'];
}
?>
