django-autocomplete-light 3.2.1 select_outside_admin

Question

I am trying to use django-autocomplete-light 3.2.1 in my Django (1.10) project with python (3.5) and I found great difficulty in using it. Then I try to follow the live demo shown in the tutorial and pull down all file to my local drive for replication (like the one on http://dal-yourlabs.rhcloud.com/select2_outside_admin/), however in vain. To me, I want to make my local demo work so that I can work my own one based on this.

Specifically, when I follow the following codes and run the site, it shows the errors of NoReverseMatch at /select2_outside_admin/ with description of Reverse for 'linked_data' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: [] I have no idea what is going wrong. I attached my codes as below and please advise what to do if you know the solution. Many thanks:
