Le modèle n'existe pas

Je suis nouveau sur Django. J'ai fait un dossier de modèles nommés dans mon projet et de l' "base.html" à l'intérieur, il fonctionne très bien. Mais quand je créer un nouveau dossier à l'intérieur de modèles de bienvenue et puis "home.html" et j'écris quelques lignes de code dans mon views.py fichier

from django.shortcuts import render_to_response

def hello(request):
    return render_to_response('welcome/home.html')

et settings.py comprend
