Indeed, you are right. I was redirecting the output using:

_stdout = sys.stdout
sys.stdout = open(os.devnull, 'w')
[run modeller]
sys.stdout.close()
sys.stdout = _stdout

But somewhere along the road I made a mistake, and it was still
showing up; so I assumed the output came from a compiled extension,
that cannot be redirected. Sorry about that.

In case this is helpful for anyone else, here is my final solution.
ContactModel inherits from and replaces automodel because I am adding
some restraints. Now make() is completely silent.


class ShutUp(object):
    def __enter__(self):
        self._stdout = sys.stdout
        sys.stdout = open(os.devnull, 'w')

    def __exit__(self, *args):
        sys.stdout.close()
        sys.stdout = self._stdout

class ContactModel(modeller.automodel.automodel):
    [...]
    def make(self):
        with ShutUp():
            super(ContactModel, self).make()
