模型：https://github.com/PaddlePaddle/PaddleRec/tree/master/models/rank/dnn

1：dataset_generator.py中zip(feature_name, [dense_feature] + sparse_feature + [label])在py3中不兼容，需要修改为list(zip(feature_name, [dense_feature] + sparse_feature + [label]))

2：get_slot_data.py文件64行print及strip()方法不兼容py3，需修改为print(s.strip(b'')) https://github.com/PaddlePaddle/PaddleRec/blob/master/models/rank/dnn/data/get_slot_data.py#L64

3：文档中的network_conf.py需要修改为代码目录中的model.py

4. dnn 文档修复
