 問題原因：

TensorFlow和protobuf版本不匹配

解決一：版本降級

先卸載

pip uninstall protobuf

 再安裝

pip install protobuf==2.6.1

 如果版本降級后報"TypeError: __init__() got an unexpected keyword argument 'syntax' "的錯誤，錯誤詳情如下：

 還有一個辦法，就是升級TensorFlow的版本，把TensorFlow的版本更新成最近版本

解決二：TensorFlow版本升級

把protobuf卸載

pip uninstall protobuf

 安裝protobuf

pip install 'protobuf>=3.0.0a3'

 升級TensorFlow

pip install --upgrade tensorflow
