django – ImportError：Python 3中没有名为’models’的模块

from django.db import models
from django.contrib.auth.models import User
from django.core.validators import MinValueValidator,MaxValueValidator

class Metric(models.Model):
  users = models.ManyToManyField(User,through = 'Vote')
  name = models.CharField(max_length = 255)

class Vote(models.Model):
  metric = models.ForeignKey(Metric,on_delete = models.CASCADE)
  user = models.ForeignKey(User,on_delete = models.CASCADE)
  rating = models.IntegerField(validators = [MinValueValidator(0),MaxValueValidator(10)])
  email = models.EmailField

  def __str__(self):
    return str(self.rating)

和这样的admin.py文件：

from django.contrib import admin
from models import Metric,Vote

admin.site.register(Metric)
admin.site.register(Vote)

使用Python 2.7.5运行时,启动应用程序运行正常.当我尝试使用Python 3.5.1运行它时,我得到错误ImportError：没有名为’models’的模块,带有这个回溯：

我已经尝试从__future__ import absolute_import添加到admin.py文件的开头,每个类似标题的Stack Overflow帖子但它没有改变错误.是什么造成的？
