This got caught in the spam filter. You typed it suspiciously fast, apparently :wink:

This usage is correct. The only problem is that you’ve not got packaged the modules, so the relative import doesn’t work. Try this:

# test.py
from test0 import *
from test1 import *

In production I would recommend running a single service per process though.
