安装tensorflow遇到 TypeError: __init__() got an unexpected keyword argument 'syntax'
根据tensorflow的官网描述，安装virtualenv installation，安装结束后测试tensorflow是否安装成功，
import tensorflow as tf
出现错误：
Traceback (most recent call last):

TypeError: __init__() got an unexpected keyword argument 'syntax'
这是由于protobuf版本太低的原因，解决方案如下：（only cpu）
pip uninstall protobuf pip install 'protobuf>=3.0.0a3' pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.6.0-cp27-none-linux_x86_64.whl
然后：
pip show numpy protobuf
出现：
Name: protobuf Version: 3.0.0b2.post2 Location: /home/yr/tensorflow/lib/python2.7/site-packages
至此，问题解决
