python kcws/train/train_cws_lstm.py出错

[chmaojian]

python 2.7.5
tensorflow 1.0.1
前面都完成了，到了第四步kcws/train/train_cws_lstm.py出错了
（跟之前一位老兄出现的问题有点相似）

提示的错误为：

之前一直按照步骤来执行的，没有修改代码，请问这是什么原因呢？谢谢~

你确认你的tensorflow是1.0.1的吗？
我也遇到这个问题，不过我的tensorflow版本是拉取了master分支编译的，版本是1.0.1rc。。。
后来我卸载了tensorflow并重新安装了1.0.1版本就好了。

问题已解决，谢谢~确实之前是master分支，重新安装1.0.1就好了，非常感谢！！！
