Tensorflow: TypeError: zeros_initializer () obteve vários valores para o argumento de palavra-chave 'dtype'

Estou tentando fazer o aprendizado distribuído do tutorial de Iniciação no TensorFlow

Meio Ambiente
_Parameter Server_
Sistema operacional: Ubuntu 16.04 LTS
Tensorflow: r 0,12
python: 2.7.12

_Trabalhador_
Sistema operacional: CentOS 7
Tensorflow: r 0,12
python: 2.7.5
Placa GPU: 2 * GTX NVIDIA 1080

mas eu tenho este erro:

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

Eu verifiquei o seguinte problema antes

( TypeError: ones_initializer () obteve vários valores para o argumento de palavra-chave 'dtype' ao executar o inception_train # 5742 )

mas parece não funcionar muito bem

Qualquer ideia? THX!
