Python attempted relative import with no known parent package

Question

I have the following project directory. scriptA.py and scriptB.py are both separate micro-services, but share largely the same codebase.

myproject
  apps/
     models/
       db.py
       ModelA.py
       ModelB.py
     scriptA.py
     scriptB.py

  scripts/
    import.py

  requirements.text
  README.md

I can run python apps/scriptA.py and python apps/scriptB.py just fine. They both import models/db and models/Model(A|b) just fine.

However, when I run python scripts/import.py , which also tries to use models/db , I get the following: attempted relative import with no known parent package

In scripts/import.py , I'm using the following relative import:

from ..apps.models.db import setup_db

def main():
  print("Main")

if __name__ == "__main__":
  main()

scripts is separated from apps , because it just contains a bunch of scripts for importing data into my database. Whereas apps contains all the code to run my applications.

Answer 1

From your command, I assume you're in myproject directory while executing python apps/scriptA.py . In that case, in import.py use:

import sys,os
sys.path.append('apps/models)

from db import setup_db

def main():
  print("Main")

if __name__ == "__main__":
  main()

Then you should run it normally.
