MacでTensorFlowのTypeError: __init__() got an unexpected keyword argument 'syntax'を解決する

GoogleのTensorFlowが凄いらしいので使ってみようと思ったらエラーが出てつまづいてしまったので、同じような境遇の人のために解決方法をメモしておきます。

インストール

$ pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

解決方法

pip uninstall protobuf
pip uninstall tensorflow
brew uninstall protobuf
pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

protobufのバージョンが3.0.0a4になっていたらOKのようです。

import google.protobuf
>>> print google.protobuf.__version__
3.0.0a4
