+```
+
+### Start Server
+
+take the fit_a_line demo as example
+
+```
+ python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393 --use_multilang #CPU
+python -m paddle_serving_server_gpu.serve --model uci_housing_model --thread 10 --port 9393 --use_multilang #GPU
+```

+mvn compile
+mvn install
+```
+
+### 启动服务端
+
+以fit_a_line模型为例
+
+```
+ python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393 --use_multilang #CPU
+python -m paddle_serving_server_gpu.serve --model uci_housing_model --thread 10 --port 9393 --use_multilang #GPU
