我正在尝试安装django-extensions以在我的 Django rest项目中可视化我的模型。完成堆栈跟踪：

我在我的设置中添加了django_extensions，
GRAPH_MODELS = {
'all_applications': True,
'group_models': True,
}
我的要求如下：
Django==1.11.12
djangorestframework==3.8.2
django-cors-headers==2.2.0
drfdocs==0.0.11
mysql-python==1.2.5
django-rest-auth==0.9.3
django-allauth==0.35.0
nltk==3.2.5
django-extensions==2.0.7
pyparsing==2.2.0
pydot==1.2.4
我在Windows 10.如何解决此错误？我是否需要在Windows路径中添加任何内容？或者对于Django休息，我需要其他库（https://github.com/chibisov/drf-extensions）
