Python Django |在ModelForm上获取循环导入错误

我正在Django中使用Form和FormModel作为我的一个应用程序。 我创建了一个模型，如下所示models.py

from django.db import models


class ImageProcessor(models.Model):
    id_image = models.ImageField(upload_to="image_dir")

我使用的表单如下（forms.py）

在终端窗口中，我看到下面的消息，我很确定这是因为

from .models import ImageProcessor

这很重要

错误消息：

django.core.exceptions.impropertlyconfigured:包含的URLconf“img_site.url”中似乎没有任何模式。如果你看到 如果文件中存在有效模式，那么问题可能是由 循环输入。

更新1：（url.py）

更新2：
