问如何修复ImportError:没有名为urls的模块？

EN

我尝试运行Django应用程序时，遇到了这样的错误：ImportError:没有模块名urls，。

这是我得到的回溯：

这是我的urls.py文件：

from django.conf.urls import patterns, include, url
from django.contrib import admin
from django import template
from django.conf.urls.i18n import i18n_patterns

urlpatterns = patterns('',
    url(r'^', include('coverage.urls')), 
    url(r'fr/', include('coverage.urls')),
    url(r'en/', include('coverage.urls')),
    url(r'ru/', include('coverage.urls')),
    url(r'zh/', include('coverage.urls')),
    url(r'^i18n/', include('django.conf.urls.i18n')),
    url(r'^accounts/', include('accounts.urls')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^demo/', include('coverage.urls')),
    url(r'^ru/demo/', include('coverage.urls')),
    url(r'^zh/demo/', include('coverage.urls')),
    url(r'^fr/demo/', include('coverage.urls')),
    url(r'^en/demo/', include('coverage.urls')),
    url(r'^analysis/', include('data_analysis.urls')),
    url(r'^telcel_stats/', include('general_stats.urls')),
)

urlpatterns += i18n_patterns(
    url(r'^', include('coverage.urls')),
)

template.add_to_builtins('django.templatetags.i18n')

我怎样才能解决这个问题？

编辑：在尝试了Krishna建议的答案后，我的回溯如下：
