Help: NoReverseMatch using Django 2.0

Hi,

I need some help. I have a NoReverseMatch message error and I don´t know how to fix it. I guess the cause is that I am using Django 2.0, but don´t know what I have to change

NoReverseMatch at /courses/1/ Reverse for 'create_quiz' with keyword arguments '{'course_pk': ''}' not found. 1 pattern(s) tried: ['courses\/(?P<course_pk>[^/]+)\/create_quiz\/$']

urls.py 
urlpatterns = [
    path('', views.course_list, name="course"),
    path('<course_pk>/<step_pk>/t', views.text_detail, name='text'),
    path('<course_pk>/<step_pk>/q', views.quiz_detail, name='quiz'),
    path('<course_pk>/create_quiz/', views.quiz_create, name='create_quiz'),
    path('<int:pk>/', views.course_detail, name='detail'),
]

I don´t know how to add different so I post in different comments

views.py 
@login_required
def quiz_create(request, course_pk):
    course = get_object_or_404(models.Course, pk=course_pk)
    form = forms.QuizForm()

    if request.method == 'POST':
        form = forms.QuizForm(request.POST)
        if form.is_valid():
            quiz = form.save(commit=False)
            quiz.course = course
            quiz.save()
            messages.add_message(request, message.SUCCESS, "Quiz added!")
            return HttpResponseRedirect(quiz.get_absolute_url())
        return render(request, 'courses/quiz_form.html', {'form': form, 'course': course})
