+This tutorial shows how to run PaddlePaddle model by opencv.
+
+## Environment Setup
+
+```shell
+pip install paddlepaddle-gpu
+pip install paddlehub
+pip install paddle2onnx
+```
+
+## Run PaddlePaddle model demo
+
+Run the example code as below,
```shell
python paddle_resnet50.py
there are 3 part of this execution
-- 1. Export PaddlePaddle ResNet50 model to onnx format
-- 2. Use `cv2.dnn.readNetFromONNX` load model file
-- 3. Preprocess image file and do inference
