Как подавить вездесущий журнал Tensorflow?

Я убираю свой код Tensorflow с помощью nosetests, но он производит такое количество подробных результатов, что делает его бесполезным.

Следующий тест

import unittest
import tensorflow as tf

class MyTest(unittest.TestCase):

    def test_creation(self):
        self.assertEquals(True, False)

при запуске с nosetests создает огромное количество бесполезного ведения журнала:

FAIL: test_creation (tests.test_tf.MyTest)

тогда как использование tensorflow из консоли ipython не выглядит таким подробным:

$ ipython
Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
Type "copyright", "credits" or "license" for more information.

Как я могу подавить прежнее ведение журнала при запуске nosetests?
