Import specific class or function in Python Parallel job

Question

If you are using some modules in a function passed to Server.submit [docs], you need to specify these in the modules argument. See below:

import os

def get_os_name():
  return os.name

jobserver.submit(get_os_name,modules=('os',))

But, I would like to do something like this:

from os import name

def get_os_name():
  return name

# Obviously won't work
jobserver.submit(get_os_name,modules=('os',))

How do I get the second code chunk to work? I tried replace 'os' with 'os.name' and stuff like that, but no luck.

Answer 1

Try this:

exec("jobserver.submit(get_os_name,modules=('os',))")
