Just add __init__.py files in all 3 folders. it should work. Infact every folder in my folder structure having __init__.py. I could run the code and see output.

Example folder structure could be as:

── airflow_home
     ├── __init__.py
     |──── dags
     │   ├── __init__.py
     │   ├── dag_1.py
     │   └── dag_2.py
     ├── common
         ├── __init__.py
         ├── foo.py
         └── bar.py

and dag_1.py code can be as:

from stackoverflow.src.questions.airflow_home.common.bar import bar_test

def main():
    bar_test()

main()

This peace of code i am running from my pycharm. Your airflow_home's folder path in my pycharm is stackoverflow/src/questions/airflow_home/

And bar.py code is

def bar_test():
    print "bar hara"
