Thank you for the suggestions. Sorry if my query is not clear. To
explain, I am trying to do loop modeling and at some situation I have to
do cooperatively for about 12 loops.
Right, but you still haven't told me what the error is.
Looking at your script, you probably need
from modeller.parallel import *
at the start. And you probably don't need to set the modeller_path
argument in the job constructor.
