The configuration here is not consistent with the config in https://github.com/dzhwinter/benchmark/pull/2/files . There is no reversed LSTM in that PR. Just simple stacked LSTM.

Remove the unused codes.

inputs = lstm
line 66 67实际可以和line 71 - lin 74行合并。

只需要对最后的lstm进行pooling即可，line 79只有一个pooling 之后的输入。
意图是为了保持和 https://github.com/dzhwinter/benchmark/blob/master/paddle/understand_sentiment_lstm.py#L74 这里一致。
