python - Airflow no module named for directory in airflow_home directory -


i'm working virtualenv. i'm trying use packages inside dag folders. current state of airflow_home directory is:

airflow_home/airflow.cfg airflow_home/airflow.db airflow_home/dags/__init__.py  airflow_home/dags/hello_world.py airflow_home/dags/support/inner.py airflow_home/dags/support/__init__.py

hello_world.py has code: 

from datetime import datetime airflow import dag airflow.operators.dummy_operator import dummyoperator airflow.operators.python_operator import pythonoperator dags.support import inner   def print_hello():     return 'hello world'  dag = dag('hello_world', description='simple tutorial dag',           schedule_interval='0 12 * * *', start_date=datetime(2017, 8, 20), catchup=false)  dummy_operator = dummyoperator(task_id='dummy_task', retries=3, dag=dag)  hello_operator = pythonoperator(task_id='hello_task', python_callable=print_hello, dag=dag)  hello_from_inner_operator = pythonoperator(task_id='hello_from_inner', python_callable=inner.hello_from_inner, dag=dag)  dummy_operator >> hello_operator hello_operator >> hello_from_inner_operator

if manually run script, runs. start airflow scheduler, 

broken dag: no module named 'dags'

error appears. i'm doing wrong, way solve ?

using from support import inner instead.

the path $airflow_home/dags added sys.path when airflow starts. search modules under dags directory.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
