PaddleHub-Lac模型部署，启动服务之后访问服务报错
收藏
文档连接：https://www.paddlepaddle.org.cn/hubdetail?name=lac&en_category=LexicalAnalysis
按着文档步骤安装部署之后，可以通过命令行、python代码进行分词调用，但是最后一步，启动PaddleHub Serving服务之后，通过python代码进行调用，或者postman发送post请求，服务端一直报错，报错信息如下，请问怎么解决？

自问自答，在官方的github里面有人遇到了同样的问题，是因为配置文件出现了问题，修改一下配置文件就可以了。连接如下 https://github.com/PaddlePaddle/PaddleHub/issues/1455 [代码] 顺便说一下官方提供的python demo其中的 import request 要改成 import requests。
