Using filters on Django 2.0

Please help to find the reason of error. Have two objects which ones returning from my view :

def managment_users_form(request):

    users = User.objects.all()
    usersinfo = usersinfo_model.objects.all()
    count_objects = users.count()
    if request.user.is_authenticated:
        username = request.user.username
        context = {
            'users': users,
            'usersinfo': usersinfo,
            'count_objects': count_objects,
        }
        return render(request, 'users.html', context)
    else:
        return redirect('login_form')

And on my template I want to make for cycle from first one and filter by id in cycle another one. First is working well, but second one I'm getting error when try to use filter.

Teamplate

{% for user in users %}
<div class="">
    <h4 class="m-b-5">{{ user.first_name }} {{ user.last_name }}</h4>
        <p class="text-muted">{{ useremp|user_info_filter:user.id }} <span></p>
    </div>
{% endfor %}

filter 

from django import template

register = template.Library()

@register.filter(name='user_info_filter')
def user_info_filter(useremp, id):
    return useremp.filter(user_id=id)

Please help to understand the mistake. Error is : "Invalid filter: 'user_info_filter'"

Did you add the filter to settings.py? It's required from 1.9 Django

ex :

'OPTIONS': {
    'context_processors': [
        'django.template.context_processors.debug',
        'django.template.context_processors.request',
        'django.contrib.auth.context_processors.auth',
        'django.contrib.messages.context_processors.messages',
    ],
    'libraries':{
        'filter': 'project_name.templatetags.filter',

    }
},
