# FastDeploy Streamer PP-YOLOE C++ Example
|
||
|
||
## 编译和运行
|
||
|
||
1. 该示例依赖DeepStream，需要准备DeepStream环境，并编译FastDeploy Streamer，请参考[README](../../../README_CN.md)
|
||
|
||
2. 编译Example
|
||
```
|
||
mkdir build && cd build
|
||
cmake .. -DFASTDEPLOY_INSTALL_DIR=[PATH-OF-FASTDEPLOY-INSTALL-DIR]
|
||
make -j
|
||
```
|
||
|
||
3. 下载模型
|
||
```
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/ppyoloe_crn_l_300e_coco_onnx_without_scale_factor.tgz
|
||
tar xvf ppyoloe_crn_l_300e_coco_onnx_without_scale_factor.tgz
|
||
mv ppyoloe_crn_l_300e_coco_onnx_without_scale_factor/ model/
|
||
```
|
||
|
||
4. 运行
|
||
```
|
||
cp ../nvinfer_config.txt .
|
||
cp ../streamer_cfg.yml .
|
||
./streamer_demo
|
||
```
|
||
|
||
## 导出ONNX模型，不包含NMS和scale factor
|
||
```
|
||
# 导出Paddle推理模型，exclude_nms=True and trt=True
|
||
git clone https://github.com/PaddlePaddle/PaddleDetection.git
|
||
cd PaddleDetection
|
||
python tools/export_model.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams exclude_nms=True trt=True --output_dir inference_model
|
||
|
||
# 转换为ONNX
|
||
paddle2onnx --model_dir inference_model/ppyoloe_crn_l_300e_coco/ --model_filename model.pdmodel --params_filename model.pdiparams --save_file ppyoloe.onnx --deploy_backend tensorrt --enable_dev_version True
|
||
|
||
# 裁剪ONNX，删除scale factor
|
||
git clone https://github.com/PaddlePaddle/Paddle2ONNX.git
|
||
cd Paddle2ONNX
|
||
python tools/onnx/prune_onnx_model.py --model ../PaddleDetection/ppyoloe.onnx --output_names concat_14.tmp_0 p2o.Mul.245 --save_file ppyoloe_without_scale_factor.onnx
|
||
```
