I want to import the Model class in module models from app1 into app2. When attempting to use from..app1.models import Model , I receive the error Attempted relative import beyond top-level package .

Answer 1

use:

import sys
sys.path.append("..")            # or sys.path.append(".")
print (os.getcwd())

from app1.models import ModelClassName
