解決這個問題的方法是：將tensro升級到最新的tendorflow的1.4版本，但是還會出現


```
AttributeError: 'NoneType' object has no attribute 'update'
```
解決辦法請參考：

``` ＃
將seq2seq_model.py中134行的
 def seq2seq_f(encoder_inputs, decoder_inputs, do_decode):
            return tf.contrib.legacy_seq2seq.embedding_attention_seq2seq(
                encoder_inputs,
                decoder_inputs,
                cell,
                num_encoder_symbols=source_vocab_size,
                num_decoder_symbols=target_vocab_size,
                embedding_size=size,
                output_projection=output_projection,
                feed_previous=do_decode,
                dtype=dtype)


改變為：
def seq2seq_f（encoder_inputs，decoder_inputs，do_decode）：
tmp_cell = copy.deepcopy（cell）
return tf.contrib.legacy_seq2seq.embedding_attention_seq2seq（
encoder_inputs，
decoder_inputs，tmp_cell，
num_encoder_symbols = source_vocab_size，
num_decoder_symbols = target_vocab_size，
embedding_size = size，
output_projection = output_projection，
feed_previous = do_decode，dtype = dtype 
）
```
