 the 128 in the command above means max_seq_len in BERT model, which is the length of sample after preprocessing.
 the config file and model file for server side are saved in the folder bert_seq128_model.
 the config file generated for client side is saved in the folder bert_seq128_client.

 示例中采用[Paddlehub](https://github.com/PaddlePaddle/PaddleHub)中的[BERT中文模型](https://www.paddlepaddle.org.cn/hubdetail?name=bert_chinese_L-12_H-768_A-12&en_category=SemanticModel)。
 请先安装paddlehub
 ```
-pip install paddlehub
+pip3 install paddlehub
 ```
 执行
 ```
-python prepare_model.py 128
+python3 prepare_model.py 128
 ```
 参数128表示BERT模型中的max_seq_len，即预处理后的样本长度。
 生成server端配置文件与模型文件，存放在bert_seq128_model文件夹。
