Upgraded from Django 1.8 to 1.10 and TemplateDoesNotExist error

Question

I upgraded my Django version from 1.8 to 1.10 and I had to remove the patterns() in various files in my site_packages folder.

I was getting errors like this:

File "C:\Python27\lib\site-packages\import_export\admin.py", line 266, in get_urls
my_urls = patterns( 
NameError: global name 'patterns' is not defined

So, per the depreciation guidelines, I changed the code to this in the admin.py file.

my_urls = [
        url(r'^process_import/$',
            self.admin_site.admin_view(self.process_import),
            name='%s_%s_process_import' % info),
        url(r'^import/$',
            self.admin_site.admin_view(self.import_action),
            name='%s_%s_import' % info),
    ]
    return my_urls + urls

I repeated this 3 times in the site_packages folder.

However I'm now getting a TemplateDoesNotExist error:

Template loader postmortem
Django tried loading these templates, in this order:

Using engine :
    This engine did not provide a list of tried templates.

I'm at a loss on what to do, and any help is appreciated. I'm sorry if I made some mistakes in detailing my code, as this is my first question here.
