ImportError: невозможно импортировать имя pywrap_dlopen_global_flags

Question

Я получаю следующую ошибку при попытке использовать tenorflow (версия - самая новая на дату публикации) на оборудовании - ЦП MacBookPro с ОС - Dual Boot Ubuntu 16.04 LTS в virtualenv —no-site-package with Keras и keras-rl и python 2,7.

...
 Using TensorFlow backend.

я использовал

site.addsitedir(os.path.expanduser('path/to/tensorflow_venv/lib/python2.7/site-packages'))

импортировать модули keras-rl при работе в другой среде

Что означает эта ошибка ImportError? Я проверил код в файле pwrap_tensorflow.py и не понимаю комментарий выше исключения.

...
try:
  # This import is expected to fail if there is an explicit shared object
  # dependency (with_framework_lib=true), since we do not need RTLD_GLOBAL.
  from tensorflow.python import pywrap_dlopen_global_flags
  _use_dlopen_global_flags = True
except ImportError:
  _use_dlopen_global_flags = False

Я также получаю проблему с protobuf. Версия protobuf в venv - 3.5.1
