+# YOLOv5s量化模型 Python部署示例
+本目录下提供的`infer.py`,可以帮助用户快速完成YOLOv5量化模型在CPU/GPU上的部署推理加速.
+
+## 部署准备
+### FastDeploy环境准备
+- 1. 软硬件环境满足要求，参考[FastDeploy环境要求](../../../../../../docs/environment.md)  
+- 2. FastDeploy Python whl包安装，参考[FastDeploy Python安装](../../../../../../docs/quick_start)
+
+### 量化模型准备
+- 1. 用户可以直接使用由FastDeploy提供的量化模型进行部署.
+- 2. 用户可以使用FastDeploy提供的[一键模型量化工具](../../../../../../tools/quantization/),自行进行模型量化, 并使用产出的量化模型进行部署.
+
+
+## 以量化后的YOLOv5s模型为例, 进行部署
+```bash
+#下载部署示例代码
+git clone https://github.com/PaddlePaddle/FastDeploy.git
+cd examples/vision/detection/yolov5/quantize/python
+
+#下载FastDeloy提供的yolov5s量化模型文件和测试图片
+wget https://bj.bcebos.com/paddlehub/fastdeploy/yolov5s_quant.tar
+tar -xvf yolov5s_quant.tar
+wget https://gitee.com/paddlepaddle/PaddleDetection/raw/release/2.4/demo/000000014439.jpg
+
+# 在CPU上使用Paddle-Inference推理量化模型
+python infer.py --model yolov5s_quant --image 000000014439.jpg --device cpu --backend paddle
+# 在GPU上使用TensorRT推理量化模型
+python infer.py --model yolov5s_quant --image 000000014439.jpg --device gpu --backend trt
+```
