   I've managed to find an ugly way to import macros in Airflow 2.0.1 on Python 3.9. It's not the original `from airflow.macros import x` method from Airflow 1.x but it is working.
   
   ```
   def get_macro(name):
       from airflow import plugins_manager
       plugins_manager.integrate_macros_plugins()
   
       for x in plugins_manager.plugins:
           if x.name == name:
               return x.macros[0]
   
       raise Exception('Unable to find macro "%s"' % name)
   
   _exec = get_macro('_exec')                                                                                        
   
   _exec('pwd')  # returns: '/home/ubuntu/airflow/dags\n'
   ```
