我在 tensoflow 存储库中找不到 seq2seq 模块

I can't find seq2seq module in tensoflow repository

我正在阅读有关 seq2seq 模型的 tensorflow 教程。它在 t***ensorflow/tensorflow/python/ops/seq2seq.py*** 中提到了源代码的位置。但是我去了之后(https://github.com/tensorflow/tensorflow/tree/master/tensorflow/python/ops)找不到源码

代码 seq2seq.py 已于 2016 年 12 月 14 日移至 https://github.com/tensorflow/tensorflow/blob/master/tensorflow/contrib/legacy_seq2seq/python/ops/seq2seq.py on commit d438a07a2f50401c6a1d5a644512cd46fba4da4f
