+# FCOS model on Paddle Serving
+
+([简体中文](./README_CN.md)|English)
+
+### Get Model
+```
+wget --no-check-certificate https://paddle-serving.bj.bcebos.com/pddet_demo/2.0/fcos_dcn_r50_fpn_1x_coco.tar
+```
+
+### Start the service
+```
+tar xf fcos_dcn_r50_fpn_1x_coco.tar
+python -m paddle_serving_server_gpu.serve --model serving_server --port 9494 --gpu_ids 0
+```
+This model support TensorRT, if you want a faster inference, please use `--use_trt`.
+
+### Perform prediction
+```
+python test_client.py 000000570688.jpg
+```

+# 使用Paddle Serving部署FCOS模型
+
+(简体中文|[English](./README.md))
+
+## 获得模型
+```
+wget --no-check-certificate https://paddle-serving.bj.bcebos.com/pddet_demo/2.0/fcos_dcn_r50_fpn_1x_coco.tar
+```
+
+
+### 启动服务
+```
+tar xf fcos_dcn_r50_fpn_1x_coco.tar
+python -m paddle_serving_server_gpu.serve --model serving_server --port 9494 --gpu_ids 0
+```
+
+该模型支持TensorRT，如果想要更快的预测速度，可以开启`--use_trt`选项。
+
+### 执行预测
+```
