Tensorflow: TypeError: zeros_initializer () получил несколько значений для аргумента ключевого слова 'dtype'

Я пытаюсь выполнить распределенное обучение из учебника Начало в TensorFlow

Среда
_Parameter Server_
Операционная система: Ubuntu 16.04 LTS
Тензорпоток: r 0,12
питон: 2.7.12

_Worker_
Операционная система: CentOS 7
Тензорпоток: r 0,12
питон: 2.7.5
Видеокарта: 2 * GTX NVIDIA 1080

но я получил эту ошибку:

TypeError: zeros_initializer() got multiple values for keyword argument 'dtype'

Я уже проверял следующую проблему раньше

( TypeError: ones_initializer () получил несколько значений для аргумента ключевого слова 'dtype' при выполнении inception_train # 5742 )

но похоже не очень хорошо работает

Любая идея? Спасибо!
