# PaddleClas RV1126 Development Board C++ Deployment Example
|
|
`infer.cc` in this directory can help you quickly complete the inference acceleration of PaddleClas quantization model deployment on RV1126.
|
|
|
|
## Deployment Preparations
|
|
### FastDeploy Cross-compile Environment Preparations
|
|
1. For the software and hardware environment, and the cross-compile environment, please refer to [Preparations for FastDeploy Cross-compile environment](../../../../../../docs/en/build_and_install/rv1126.md#Cross-compilation-environment-construction).
|
|
|
|
### Model Preparations
|
|
1. You can directly use the quantized model provided by FastDeploy for deployment.
|
|
2. You can use [one-click automatical compression tool](../../../../../../tools/common_tools/auto_compression/) provided by FastDeploy to quantize model by yourself, and use the generated quantized model for deployment.(Note: The quantized classification model still needs the inference_cls.yaml file in the FP32 model folder. Self-quantized model folder does not contain this yaml file, you can copy it from the FP32 model folder to the quantized model folder.)
|
|
|
|
For more information, please refer to [Model Quantization](../../quantize/README.md).
|

## Deploying the Quantized ResNet50_Vd Segmentation model on RV1126
|
|
Please follow these steps to complete the deployment of the ResNet50_Vd quantization model on RV1126.
|
|
1. Cross-compile the FastDeploy library as described in [Cross-compile FastDeploy](../../../../../../docs/en/build_and_install/rv1126.md#FastDeploy-cross-compilation-library-compilation-based-on-Paddle-Lite).
|
|
|
|
2. Copy the compiled library to the current directory. You can run this line:
|
|
```bash
|
|
cp -r FastDeploy/build/fastdeploy-timvx/ FastDeploy/examples/vision/classification/paddleclas/rv1126/cpp/
|
|
```
|
|
|
|
3. Download the model and example images required for deployment in current path.
|
|
```bash
|
|
cd FastDeploy/examples/vision/classification/paddleclas/rv1126/cpp/
|
|
mkdir models && mkdir images
|
|
wget https://bj.bcebos.com/paddlehub/fastdeploy/resnet50_vd_ptq.tar
|
|
tar -xvf resnet50_vd_ptq.tar
|
|
cp -r resnet50_vd_ptq models
|
|
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
|
|
cp -r ILSVRC2012_val_00000010.jpeg images
|
|
```
|
|
|
|
4. Compile the deployment example. You can run the following lines:
|
|
```bash
|
|
cd FastDeploy/examples/vision/classification/paddleclas/rv1126/cpp/
|
|
mkdir build && cd build
|
|
cmake -DCMAKE_TOOLCHAIN_FILE=${PWD}/../fastdeploy-timvx/toolchain.cmake -DFASTDEPLOY_INSTALL_DIR=${PWD}/../fastdeploy-timvx -DTARGET_ABI=armhf ..
|
|
make -j8
|
|
make install
|
|
# After success, an install folder will be created with a running demo and libraries required for deployment.
|
|
```
|
|
|
|
5. Deploy the ResNet50 segmentation model to Rockchip RV1126 based on adb. You can run the following lines:
|
|
```bash
|
|
# Go to the install directory.
|
|
cd FastDeploy/examples/vision/classification/paddleclas/rv1126/cpp/build/install/
|
|
# The following line represents: bash run_with_adb.sh, demo needed to run, model path, image path, DEVICE ID.
|
|
bash run_with_adb.sh infer_demo resnet50_vd_ptq ILSVRC2012_val_00000010.jpeg $DEVICE_ID
|
|
```
|
|
|
|
The output is:
|
|

|
|
|
|
Please note that the model deployed on RV1126 needs to be quantized. You can refer to [Model Quantization](../../../../../../docs/en/quantize.md).
