Import "rest_framework" could not be resolved "django-rest-framework"

I have installed the Django framework but it always shows a yellow line under it as if the project is not defined

Settings.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django_filters',
'rest_framework',
'rest_framework.authtoken',
'rest_framework.routers',
'hauptapp', 
]

views.py

Zb Import "rest_framework" could not be resolved
