AttributeError

[Jackie Wang]

hi，
說明很清楚了，但在train時，有碰到AttributeError，不知你有沒有碰到同樣的問題。

error log 如下：
write_version=tf.train.SaverDef.V2

return io_ops.save_v2(filename_tensor, tensor_names, tensor_slices,

应该是tensorflow版本的问题

我用的最新tf 0.11.0 rc1版本的，这个版本开始存储格式用了SaverDef.V2

你可以考虑删掉s2s_model.py文件第106行的
write_version=tf.train.SaverDef.V2
应该就会好

～～或者考虑开个virtualenv装个最新版tf试试

write_version=tf.train.SaverDef.V2 删除以后依然报错，错误信息

请问是什么原因导致的？

也许是不支持2.7导致的吧，作者说的是支持3.5
