accès impossible à Faker\Factory

Bonjour,

Voila je rencontre un petit problème avec mon code.

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\HttpFoundation\Request;
use Doctrine\ORM\EntityManagerInterface;
use App\Entity\Article;
use App\Form\ArticleType;
use App\Repository\ArticleRepository;
use Fake\Factory;

class BlogController extends AbstractController
{
/**

• @Route("/", name="home")
  */
  public function home(){
  $form = Factory::create('Fr_fr');
  var_dump($form);
  return $this->render('blog/home.html.twig');
  }

  /**

• @Route("/blog", name="blog")
  */
  public function index(ArticleRepository $repo)
  {
  $articles = $repo->findAll();
  return $this->render('blog/index.html.twig', [
  'controller_name' => 'BlogController',
  'articles' => $articles,
  ]);
  }

  /**

• For create an article
• @Route("/blog/new", name="blog_create")

• @Route("/blog/{id}/edit", name="blog_edit")
  */
  public function form(Article $article = null, Request $request, EntityManagerInterface $manager){
  ($article) ? null : $article = new Article();

  // $form =$this->createFormBuilder($article)
  //             ->add('title')
  //             ->add('content')
  //             ->add('image')
  //             ->getForm();
  
  $form = $this->createForm(ArticleType::class, $article);    //Création de l'objet de formulaire
  
  $form->handleRequest($request); //Analyse de la requêtte et remplissage si besoin de l'article
  if($form->isSubmitted() && $form->isValid()){
      ($article->getId()) ? null : $article->setCreatedAt(new \DateTime());
      $manager->persist($article);
      $manager->flush();
      return $this->redirectToRoute('blog_show', ['id' => $article->getId()]);
  }
  
  return $this->render("blog/form.html.twig", [
      'formArticle' => $form->createView(),
      'editMode' => $article->getId() !== null
      ]);

  }

  /**

• @Route("/blog/{id}", name="blog_show")
  */
  public function show(Article $article){
  return $this->render("blog/show.html.twig", [
  'article' => $article,
  ]);
  }
  }

Je voudrais utiliser un Faker pour générer des fixtures, mais le framework ne retrouve pas la librairie et renvoie le message suivant :
