## 五.昇腾部署时开启FlyCV
[FlyCV](https://github.com/PaddlePaddle/FlyCV) 是一款高性能计算机图像处理库, 针对ARM架构做了很多优化, 相比其他图像处理库性能更为出色.
FastDeploy现在已经集成FlyCV, 用户可以在支持的硬件平台上使用FlyCV, 实现模型端到端推理性能的加速.
模型端到端推理中, 预处理和后处理阶段为CPU计算, 当用户使用ARM CPU + 昇腾的硬件平台时, 我们推荐用户使用FlyCV, 可以实现端到端的推理性能加速, 详见[FLyCV使用文档](./boost_cv_by_flycv.md).

# PP-Matting C++ Deployment Example
This directory provides examples that `infer.cc` fast finishes the deployment of PP-Matting on CPU/GPU and GPU accelerated by TensorRT.
Before deployment, two steps require confirmation
- 1. Software and hardware should meet the requirements. Please refer to [FastDeploy Environment Requirements](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)
- 2. Download the precompiled deployment library and samples code according to your development environment. Refer to [FastDeploy Precompiled Library](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)
Taking the PP-Matting inference on Linux as an example, the compilation test can be completed by executing the following command in this directory. FastDeploy version 0.7.0 or above (x.x.x>=0.7.0) is required to support this model.
```bash

# PP-LiteSeg 量化模型 C++ 部署示例
`infer.cc` in this directory can help you quickly complete the inference acceleration of PP-LiteSeg quantization model deployment on A311D.
本目录下提供的 `infer.cc`，可以帮助用户快速完成 PP-LiteSeg 量化模型在晶晨 A311D 上的部署推理加速。
## Deployment Preparations
### FastDeploy Cross-compile Environment Preparations
1. For the software and hardware environment, and the cross-compile environment, please refer to [FastDeploy Cross-compile environment](../../../../../../docs/en/build_and_install/a311d.md#Cross-compilation-environment-construction).
## 部署准备
### FastDeploy 交叉编译环境准备
软硬件环境满足要求，以及交叉编译环境的准备，请参考：[FastDeploy](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#自行编译安装)
### Model Preparations
1. You can directly use the quantized model provided by FastDeploy for deployment.
2. You can use one-click automatical compression tool provided by FastDeploy to quantize model by yourself, and use the generated quantized model for deployment.(Note: The quantized classification model still needs the deploy.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.)
3. The model requires heterogeneous computation. Please refer to: [Heterogeneous Computation](./../../../../../../docs/en/faq/heterogeneous_computing_on_timvx_npu.md). Since the model is already provided, you can test the heterogeneous file we provide first to verify whether the accuracy meets the requirements.
### 模型准备
1. 用户可以直接使用由[FastDeploy 提供的量化模型](../README_CN.md#晶晨a311d支持的paddleseg模型)进行部署。
2. 若FastDeploy没有提供满足要求的量化模型，用户可以参考[PaddleSeg动态图模型导出为A311D支持的INT8模型](../README_CN.md#paddleseg动态图模型导出为a311d支持的int8模型)自行导出或训练量化模型
3. 若上述导出或训练的模型出现精度下降或者报错，则需要使用异构计算，使得模型算子部分跑在A311D的ARM CPU上进行调试以及精度验证，其中异构计算所需的文件是subgraph.txt。具体关于异构计算可参考：[异构计算](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/faq/heterogeneous_computing_on_timvx_npu.md)。
For more information, please refer to [Model Quantization](../../quantize/README.md)

# PP-LiteSeg 量化模型 C++ 部署示例
本目录下提供的 `infer.cc`，可以帮助用户快速完成 PP-LiteSeg 量化模型在 晶晨A311D 上的部署推理加速。
## 部署准备
### FastDeploy 交叉编译环境准备
1. 软硬件环境满足要求，以及交叉编译环境的准备，请参考：[FastDeploy 交叉编译环境准备](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install/a311d.md#交叉编译环境搭建)
### 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 提供的一键模型自动化压缩工具,自行进行模型量化, 并使用产出的量化模型进行部署.(注意: 推理量化后的分类模型仍然需要FP32模型文件夹下的 deploy.yaml 文件, 自行量化的模型文件夹内不包含此 yaml 文件, 用户从FP32模型文件夹下复制此yaml文件到量化后的模型文件夹内即可.)
3. 模型需要异构计算，异构计算文件可以参考：[异构计算](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/faq/heterogeneous_computing_on_timvx_npu.md)，由于 FastDeploy 已经提供了模型，可以先测试我们提供的异构文件，验证精度是否符合要求。
更多量化相关相关信息可查阅[模型量化](../../../quantize/README.md)
## 在 A311D 上部署量化后的 PP-LiteSeg 分割模型
请按照以下步骤完成在 A311D 上部署 PP-LiteSeg 量化模型：
1. 交叉编译编译 FastDeploy 库，具体请参考：[交叉编译 FastDeploy](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install/a311d.md#基于-paddle-lite-的-fastdeploy-交叉编译库编译)
2. 将编译后的库拷贝到当前目录，可使用如下命令：
```bash
cp -r FastDeploy/build/fastdeploy-timvx/ FastDeploy/examples/vision/segmentation/paddleseg/amlogic/a311d/cpp
```
3. 在当前路径下载部署所需的模型和示例图片：
```bash
cd FastDeploy/examples/vision/segmentation/paddleseg/amlogic/a311d/cpp
mkdir models && mkdir images
wget https://bj.bcebos.com/fastdeploy/models/rk1/ppliteseg.tar.gz
tar -xvf ppliteseg.tar.gz
cp -r ppliteseg models
wget https://paddleseg.bj.bcebos.com/dygraph/demo/cityscapes_demo.png
cp -r cityscapes_demo.png images
```
4. 编译部署示例，可使入如下命令：
```bash
cd FastDeploy/examples/vision/segmentation/paddleseg/amlogic/a311d/cpp
mkdir build && cd build
cmake -DCMAKE_TOOLCHAIN_FILE=${PWD}/../fastdeploy-timvx/toolchain.cmake -DFASTDEPLOY_INSTALL_DIR=${PWD}/../fastdeploy-timvx -DTARGET_ABI=arm64 ..
make -j8
make install
# 成功编译之后，会生成 install 文件夹，里面有一个运行 demo 和部署所需的库
```
5. 基于 adb 工具部署 PP-LiteSeg 分割模型到晶晨 A311D，可使用如下命令：
```bash
# 进入 install 目录
cd FastDeploy/examples/vision/segmentation/paddleseg/amlogic/a311d/cpp/build/install/
# 如下命令表示：bash run_with_adb.sh 需要运行的demo 模型路径 图片路径 设备的DEVICE_ID
bash run_with_adb.sh infer_demo ppliteseg cityscapes_demo.png $DEVICE_ID
```

# PaddleSeg Quantized Model Deployment
FastDeploy already supports the deployment of quantitative models and provides a tool to automatically compress model with just one click.
You can use the one-click automatical model compression tool to quantify and deploy the models, or directly download the quantified models provided by FastDeploy for deployment.
[English](README.md) | 简体中文
# PaddleSeg 量化模型部署
FastDeploy已支持部署量化模型,并提供一键模型自动化压缩的工具.
用户可以使用一键模型自动化压缩工具,自行对模型量化后部署, 也可以直接下载FastDeploy提供的量化模型进行部署.
## FastDeploy One-Click Automation Model Compression Tool
FastDeploy provides an one-click automatical model compression tool that can quantify a model simply by entering configuration file.
For details, please refer to [one-click automatical compression tool](../../../../../tools/common_tools/auto_compression/).
Note: The quantized classification model still needs the deploy.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.
## FastDeploy一键模型自动化压缩工具
FastDeploy 提供了一键模型自动化压缩工具, 能够简单地通过输入一个配置文件, 对模型进行量化.
详细教程请见: [一键模型自动化压缩工具](https://github.com/PaddlePaddle/FastDeploy/tree/develop/tools/common_tools/auto_compression)
>> **注意**: 推理量化后的分类模型仍然需要FP32模型文件夹下的deploy.yaml文件, 自行量化的模型文件夹内不包含此yaml文件, 用户从FP32模型文件夹下复制此yaml文件到量化后的模型文件夹内即可。
## Download the Quantized PaddleSeg Model
You can also directly download the quantized models in the following table for deployment (click model name to download).
## 量化完成的PaddleSeg模型
用户也可以直接下载下表中的量化模型进行部署.(点击模型名字即可下载)
Note:
- Runtime latency is the inference latency of the model on various Runtimes, including CPU->GPU data copy, GPU inference, and GPU->CPU data copy time. It does not include the respective pre and post processing time of the models.
- The end-to-end latency is the latency of the model in the actual inference scenario, including the pre and post processing of the model.
- The measured latencies are averaged over 1000 inferences, in milliseconds.
- INT8 + FP16 is to enable the FP16 inference option for Runtime while inferring the INT8 quantization model.
- INT8 + FP16 + PM is the option to use Pinned Memory while inferring INT8 quantization model and turning on FP16, which can speed up the GPU->CPU data copy speed.
- The maximum speedup ratio is obtained by dividing the FP32 latency by the fastest INT8 inference latency.
- The strategy is quantitative distillation training, using a small number of unlabeled data sets to train the quantitative model, and verify the accuracy on the full validation set, INT8 accuracy does not represent the highest INT8 accuracy.
- The CPU is Intel(R) Xeon(R) Gold 6271C with a fixed CPU thread count of 1 in all tests. The GPU is Tesla T4, TensorRT version 8.4.15.

## Prepare PaddleSeg Deployment Model and Conversion Model
RKNPU needs to convert the Paddle model to RKNN model before deploying, the steps are as follows:
* For the conversion of Paddle dynamic diagram model to ONNX model, please refer to [PaddleSeg Model Export](https://github.com/PaddlePaddle/PaddleSeg/tree/release/2.6/contrib/PP-HumanSeg).
* For the process of converting ONNX model to RKNN model, please refer to [Conversion document](../../../../../docs/en/faq/rknpu2/export.md).
## 准备PaddleSeg部署模型以及转换模型
RKNPU部署模型前需要将Paddle模型转换成RKNN模型，具体步骤如下:
* PaddleSeg训练模型导出为推理模型，请参考[PaddleSeg模型导出说明](https://github.com/PaddlePaddle/PaddleSeg/blob/develop/docs/model_export_cn.md)，也可以使用上表中的FastDeploy的预导出模型
* Paddle模型转换为ONNX模型，请参考[Paddle2ONNX](https://github.com/PaddlePaddle/Paddle2ONNX)
* ONNX模型转换RKNN模型的过程，请参考[转换文档](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/faq/rknpu2/export.md)进行转换。

The input requirement for the model on RKNPU is to use NHWC format, and image normalization will be embedded into the model when converting the RKNN model, so we need to call DisableNormalizeAndPermute(C++) or disable_normalize_and_permute(Python) first when deploying with FastDeploy to disable normalization and data format conversion in the preprocessing stage.

```
## Notes
The input requirement for the model on RKNPU is to use NHWC format, and image normalization will be embedded into the model when converting the RKNN model, so we need to call DisableNormalizeAndPermute(C++) or disable_normalize_and_permute(Python) first when deploying with FastDeploy to disable normalization and data format conversion in the preprocessing stage.
## 注意事项
RKNPU上对模型的输入要求是使用NHWC格式，且图片归一化操作会在转RKNN模型时，内嵌到模型中，因此我们在使用FastDeploy部署时，需要先调用DisableNormalizeAndPermute(C++)或`disable_normalize_and_permute(Python)，在预处理阶段禁用归一化以及数据格式的转换。

**注意**
- PaddleSeg量化模型包含`model.pdmodel`、`model.pdiparams`、`deploy.yaml`和`subgraph.txt`四个文件，FastDeploy会从yaml文件中获取模型在推理时需要的预处理信息，subgraph.txt是为了异构计算而存储的配置文件
- 若以上列表中无满足要求的模型，可参考下方教程自行导出适配A311D的模型
## Detailed Deployment Tutorials
## PaddleSeg动态图模型导出为RV1126支持的INT8模型
模型导出分为以下两步
1. PaddleSeg训练的动态图模型导出为推理静态图模型，请参考其文档说明[模型导出](https://github.com/PaddlePaddle/PaddleSeg/blob/develop/docs/model_export_cn.md)
瑞芯微RV1126仅支持INT8
2. 将推理模型量化压缩为INT8模型，FastDeploy模型量化的方法及一键自动化压缩工具可以参考[模型量化](../../../quantize/README.md)
Only C++ deployment is supported 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).
## 部署准备
### FastDeploy 交叉编译环境准备
软硬件环境满足要求，以及交叉编译环境的准备，请参考：[瑞芯微RV1126部署环境](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#自行编译安装)
### Model Preparations
1. You can directly use the quantized model provided by FastDeploy for deployment.
2. You can use one-click automatical compression tool provided by FastDeploy to quantize model by yourself, and use the generated quantized model for deployment.(Note: The quantized classification model still needs the deploy.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.)
3. The model requires heterogeneous computation. Please refer to: [Heterogeneous Computation](./../../../../../../docs/en/faq/heterogeneous_computing_on_timvx_npu.md). Since the model is already provided, you can test the heterogeneous file we provide first to verify whether the accuracy meets the requirements.
### 模型准备
1. 用户可以直接使用由[FastDeploy 提供的量化模型](../README_CN.md#瑞芯微-rv1126-支持的paddleseg模型)进行部署。
2. 若FastDeploy没有提供满足要求的量化模型，用户可以参考[PaddleSeg动态图模型导出为RV1126支持的INT8模型](../README_CN.md#paddleseg动态图模型导出为rv1126支持的int8模型)自行导出或训练量化模型
3. 若上述导出或训练的模型出现精度下降或者报错，则需要使用异构计算，使得模型算子部分跑在RV1126的ARM CPU上进行调试以及精度验证，其中异构计算所需的文件是subgraph.txt。具体关于异构计算可参考：[异构计算](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/faq/heterogeneous_computing_on_timvx_npu.md)。
For more information, please refer to [Model Quantization](../../quantize/README.md).

# PaddleSeg C++部署示例
## 支持模型列表
- [PP-LiteSeg系列模型](https://github.com/PaddlePaddle/PaddleSeg/blob/develop/configs/pp_liteseg/README.md)
为了方便开发者的测试，下面提供了PaddleSeg导出的部分推理模型，开发者可直接下载使用。
PaddleSeg模型导出，请参考其文档说明[模型导出](https://github.com/PaddlePaddle/PaddleSeg/blob/develop/docs/model_export_cn.md)
| 模型 | 参数文件大小 |输入Shape | mIoU | mIoU (flip) | mIoU (ms+flip) |
|:---------------------------------------------------------------- |:----- |:----- | :----- | :----- | :----- |
| [PP-LiteSeg-T(STDC1)-cityscapes-without-argmax](https://bj.bcebos.com/fastdeploy/models/rk1/ppliteseg.tar.gz)| 31MB | 1024x512 | 77.04% | 77.73% | 77.46% |
## 准备PP-LiteSeg部署模型以及转换模型
SOPHGO-TPU部署模型前需要将Paddle模型转换成bmodel模型，具体步骤如下:
- 下载Paddle模型[PP-LiteSeg-B(STDC2)-cityscapes-without-argmax](https://bj.bcebos.com/paddlehub/fastdeploy/PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz)
- Paddle模型转换为ONNX模型，请参考[Paddle2ONNX](https://github.com/PaddlePaddle/Paddle2ONNX)
- ONNX模型转换bmodel模型的过程，请参考[TPU-MLIR](https://github.com/sophgo/tpu-mlir)
## 模型转换example
下面以[PP-LiteSeg-B(STDC2)-cityscapes-without-argmax](https://bj.bcebos.com/paddlehub/fastdeploy/PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz)为例子,教大家如何转换Paddle模型到SOPHGO-TPU模型
### 下载PP-LiteSeg-B(STDC2)-cityscapes-without-argmax模型,并转换为ONNX模型
```shell
# 下载Paddle2ONNX仓库
git clone https://github.com/PaddlePaddle/Paddle2ONNX
# 下载Paddle静态图模型并为Paddle静态图模型固定输入shape
## 进入为Paddle静态图模型固定输入shape的目录
cd Paddle2ONNX/tools/paddle
wget https://bj.bcebos.com/paddlehub/fastdeploy/PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz
tar xvf PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz
# 修改PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer模型的输入shape，由动态输入变成固定输入
python paddle_infer_shape.py --model_dir PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer \
--model_filename model.pdmodel \
--params_filename model.pdiparams \
--save_dir pp_liteseg_fix \
--input_shape_dict="{'x':[1,3,512,512]}"
#将固定输入的Paddle模型转换成ONNX模型
paddle2onnx --model_dir pp_liteseg_fix \
--model_filename model.pdmodel \
--params_filename model.pdiparams \
--save_file pp_liteseg.onnx \
--enable_dev_version True
```
### 导出bmodel模型
以转换BM1684x的bmodel模型为例子，我们需要下载[TPU-MLIR](https://github.com/sophgo/tpu-mlir)工程，安装过程具体参见[TPU-MLIR文档](https://github.com/sophgo/tpu-mlir/blob/master/README.md)。
### 1. 安装
``` shell
docker pull sophgo/tpuc_dev:latest
# myname1234是一个示例，也可以设置其他名字
docker run --privileged --name myname1234 -v $PWD:/workspace -it sophgo/tpuc_dev:latest
source ./envsetup.sh
./build.sh
```
### 2. ONNX模型转换为bmodel模型
``` shell
mkdir pp_liteseg && cd pp_liteseg
#在该文件中放入测试图片，同时将上一步转换的pp_liteseg.onnx放入该文件夹中
cp -rf ${REGRESSION_PATH}/dataset/COCO2017 .
cp -rf ${REGRESSION_PATH}/image .
#放入onnx模型文件pp_liteseg.onnx
mkdir workspace && cd workspace
#将ONNX模型转换为mlir模型，其中参数--output_names可以通过NETRON查看
model_transform.py \
--model_name pp_liteseg \
--model_def ../pp_liteseg.onnx \
--input_shapes [[1,3,512,512]] \
--mean 0.0,0.0,0.0 \
--scale 0.0039216,0.0039216,0.0039216 \
--keep_aspect_ratio \
--pixel_format rgb \
--output_names bilinear_interp_v2_6.tmp_0 \
--test_input ../image/dog.jpg \
--test_result pp_liteseg_top_outputs.npz \
--mlir pp_liteseg.mlir
#将mlir模型转换为BM1684x的F32 bmodel模型
model_deploy.py \
--mlir pp_liteseg.mlir \
--quantize F32 \
--chip bm1684x \
--test_input pp_liteseg_in_f32.npz \
--test_reference pp_liteseg_top_outputs.npz \
--model pp_liteseg_1684x_f32.bmodel
```
最终获得可以在BM1684x上能够运行的bmodel模型pp_liteseg_1684x_f32.bmodel。如果需要进一步对模型进行加速，可以将ONNX模型转换为INT8 bmodel，具体步骤参见[TPU-MLIR文档](https://github.com/sophgo/tpu-mlir/blob/master/README.md)。
