Answered 2017-Jul-24 at 14:53Not directly related to your problem, but you don't need to import airflow.models
in your case just do from airflow.models import DAG
and do the necessary changes.
You pointed to an example which shows a DAG with PythonOperator
generating tasks dynamically, but you seem that you didn't quite understood it.
In your case you must assign tasks names dynamically, so that each new task can be registered and shown in the webserver.
