# Paddle-Lite端侧部署
本教程将介绍基于[Paddle Lite](https://github.com/PaddlePaddle/Paddle-Lite) 在移动端部署PaddleDetection模型的详细步骤。
Paddle Lite是飞桨轻量化推理引擎，为手机、IOT端提供高效推理能力，并广泛整合跨平台硬件，为端侧部署及应用落地问题提供轻量化的部署方案。
## 1. 准备环境
### 运行准备
- 电脑（编译Paddle Lite）
- 安卓手机（armv7或armv8）
### 1.1 准备交叉编译环境
交叉编译环境用于编译 Paddle Lite 和 PaddleDetection 的C++ demo。
支持多种开发环境，不同开发环境的编译流程请参考对应文档，请确保安装完成Java jdk、Android NDK(R17以上)。
1. [Docker](https://paddle-lite.readthedocs.io/zh/latest/source_compile/compile_env.html#docker)
2. [Linux](https://paddle-lite.readthedocs.io/zh/latest/source_compile/compile_env.html#linux)
3. [MAC OS](https://paddle-lite.readthedocs.io/zh/latest/source_compile/compile_env.html#mac-os)
### 1.2 准备预测库
预测库有两种获取方式：
1. 直接下载，预测库下载链接如下：
|平台|预测库下载链接|
|-|-|
|Android|[arm7](https://github.com/PaddlePaddle/Paddle-Lite/releases/download/v2.8/inference_lite_lib.android.armv7.gcc.c++_static.with_extra.with_cv.tar.gz) / [arm8](https://github.com/PaddlePaddle/Paddle-Lite/releases/download/v2.8/inference_lite_lib.android.armv8.gcc.c++_static.with_extra.with_cv.tar.gz)|
**注意**：1. 目前FOM的算子只在PaddleLite的develop版本中支持，需要自行下载编译 2.如果是从 Paddle-Lite [官方文档](https://paddle-lite.readthedocs.io/zh/latest/quick_start/release_lib.html#android-toolchain-gcc)下载的预测库，注意选择`with_extra=ON，with_cv=ON`的下载链接。3. 目前只提供Android端demo.
2. 编译Paddle-Lite得到预测库，Paddle-Lite的编译方式如下：
```shell
git clone https://github.com/PaddlePaddle/Paddle-Lite.git
cd Paddle-Lite
# 如果使用编译方式，建议使用develop分支编译预测库
git checkout develop
./lite/tools/build_android.sh --arch=armv8 --with_cv=ON --with_extra=ON
```
**注意**：编译Paddle-Lite获得预测库时，需要打开`--with_cv=ON --with_extra=ON`两个选项，`--arch`表示`arm`版本，这里指定为armv8，更多编译命令介绍请参考[链接](https://paddle-lite.readthedocs.io/zh/latest/source_compile/compile_andriod.html#id2)。
直接下载预测库并解压后，可以得到`inference_lite_lib.android.armv8.gcc.c++_static.with_extra.with_cv/`文件夹，通过编译Paddle-Lite得到的预测库位于`Paddle-Lite/build.lite.android.armv8.gcc/inference_lite_lib.android.armv8/`文件夹下。
预测库的文件目录如下：
```
inference_lite_lib.android.armv8/
|-- cxx C++ 预测库和头文件
| |-- include C++ 头文件
| | |-- paddle_api.h
| | |-- paddle_image_preprocess.h
| | |-- paddle_lite_factory_helper.h
| | |-- paddle_place.h
| | |-- paddle_use_kernels.h
| | |-- paddle_use_ops.h
| | `-- paddle_use_passes.h
| `-- lib C++预测库
| |-- libpaddle_api_light_bundled.a C++静态库
| `-- libpaddle_light_api_shared.so C++动态库
|-- java Java预测库
| |-- jar
| | `-- PaddlePredictor.jar
| |-- so
| | `-- libpaddle_lite_jni.so
| `-- src
|-- demo C++和Java示例代码
| |-- cxx C++ 预测库demo
| `-- java Java 预测库demo
```
## 2 开始运行
### 2.1 模型优化
Paddle-Lite 提供了多种策略来自动优化原始的模型，其中包括量化、子图融合、混合调度、Kernel优选等方法，使用Paddle-Lite的`opt`工具可以自动对inference模型进行优化，目前支持两种优化方式，优化后的模型更轻量，模型运行速度更快。
**注意**：如果已经准备好了 `.nb` 结尾的模型文件，可以跳过此步骤。
#### 2.1.1 安装paddle_lite_opt工具
安装paddle_lite_opt工具有如下两种方法：
1. [**建议**]pip安装paddlelite并进行转换
```shell
pip install paddlelite
```
2. 源码编译Paddle-Lite生成opt工具
模型优化需要Paddle-Lite的`opt`可执行文件，可以通过编译Paddle-Lite源码获得，编译步骤如下：
```shell
# 如果准备环境时已经clone了Paddle-Lite，则不用重新clone Paddle-Lite
git clone https://github.com/PaddlePaddle/Paddle-Lite.git
cd Paddle-Lite
git checkout develop
# 启动编译
./lite/tools/build.sh build_optimize_tool
```
编译完成后，`opt`文件位于`build.opt/lite/api/`下，可通过如下方式查看`opt`的运行选项和使用方式；
```shell
cd build.opt/lite/api/
./opt
```
`opt`的使用方式与参数与上面的`paddle_lite_opt`完全一致。
之后使用`paddle_lite_opt`工具可以进行inference模型的转换。`paddle_lite_opt`的部分参数如下：
|选项|说明|
|-|-|
|--model_file|待优化的PaddlePaddle模型（combined形式）的网络结构文件路径|
|--param_file|待优化的PaddlePaddle模型（combined形式）的权重文件路径|
|--optimize_out_type|输出模型类型，目前支持两种类型：protobuf和naive_buffer，其中naive_buffer是一种更轻量级的序列化/反序列化实现，默认为naive_buffer|
|--optimize_out|优化模型的输出路径|
|--valid_targets|指定模型可执行的backend，默认为arm。目前可支持x86、arm、opencl、npu、xpu，可以同时指定多个backend(以空格分隔)，Model Optimize Tool将会自动选择最佳方式。如果需要支持华为NPU（Kirin 810/990 Soc搭载的达芬奇架构NPU），应当设置为npu, arm|
更详细的`paddle_lite_opt`工具使用说明请参考[使用opt转化模型文档](https://paddle-lite.readthedocs.io/zh/latest/user_guides/opt/opt_bin.html)
`--model_file`表示inference模型的model文件地址，`--param_file`表示inference模型的param文件地址；`optimize_out`用于指定输出文件的名称（不需要添加`.nb`的后缀）。直接在命令行中运行`paddle_lite_opt`，也可以查看所有参数及其说明。
#### 2.1.3 FOM转换示例
```shell
# 将inference模型转化为Paddle-Lite优化模型
paddle_lite_opt --model_file=output_inference/fom_dy2st/generator.pdmodel \
--param_file=output_inference/fom_dy2st/generator.pdiparams \
--optimize_out=output_inference/fom_dy2st/generator_lite \
--optimize_out_type=naive_buffer \
--valid_targets=arm
paddle_lite_opt --model_file=output_inference/fom_dy2st/kp_detector.pdmodel \
--param_file=output_inference/fom_dy2st/kp_detector.pdiparams \
--optimize_out=output_inference/fom_dy2st/kp_detector_lite \
--optimize_out_type=naive_buffer \
--valid_targets=arm
```
最终在当前文件夹下生成`generator_lite.nb`和`kp_detector_lite.nb`的文件。
**注意**：`--optimize_out` 参数为优化后模型的保存路径，无需加后缀`.nb`；`--model_file` 参数为模型结构信息文件的路径，`--param_file` 参数为模型权重信息文件的路径，请注意文件名。
### 2.2 与手机联调
首先需要进行一些准备工作。
1. 准备一台arm8的安卓手机，如果编译的预测库和opt文件是armv7，则需要arm7的手机，并修改Makefile中`ARM_ABI = arm7`。
2. 电脑上安装ADB工具，用于调试。 ADB安装方式如下：
2.1. MAC电脑安装ADB:
```shell
brew cask install android-platform-tools
```
2.2. Linux安装ADB
```shell
sudo apt update
sudo apt install -y wget adb
```
2.3. Window安装ADB
win上安装需要去谷歌的安卓平台下载ADB软件包进行安装：[链接](https://developer.android.com/studio)
3. 手机连接电脑后，开启手机`USB调试`选项，选择`文件传输`模式，在电脑终端中输入：
```shell
adb devices
```
如果有device输出，则表示安装成功，如下所示：
```
List of devices attached
744be294 device
```
4. 准备优化后的模型、预测库文件、测试图像和类别映射文件, 导入手机等运行，目前apk还存在一些效果问题，还在优化中。
## FAQ
Q1：如果想更换模型怎么办，需要重新按照流程走一遍吗？
A1：如果已经走通了上述步骤，更换模型只需要替换 `.nb` 模型文件即可，同时要注意修改下配置文件中的 `.nb` 文件路径以及类别映射文件（如有必要）。

### 2. 模型压缩
数据处理同上述，模型分为kp_detector和generator，首先固定原始generator部分，训练压缩版的kp_detector部分，然后固定原始kp_detector部分,去训练generator部分，最后将两个压缩的模型一起训练，同时添加中间的蒸馏loss。
**预测:**
```
cd applications/
python -u tools/first-order-demo.py \
--driving_video ../docs/imgs/mayiyahei.MP4 \
--source_image ../docs/imgs/father_23.jpg \
--config ../configs/firstorder_vox_mobile_256.yaml \
--ratio 0.4 \
--relative \
--adapt_scale \
--mobile_net
```
目前压缩采用mobilenet+剪枝的方法，和之前对比：
| | 大小(M) | reconstruction loss |
| :--------------: | :--------------: | :-----------------: |
| 原始 | 229 | 0.012058867 |
| 压缩 | 6.1 | 0.015025159 |
### 3. 模型部署
#### 3.1 导出模型
使用`tools/fom_export.py`脚本导出模型已经部署时使用的配置文件，配置文件名字为`firstorder_vox_mobile_256.yml`。模型导出脚本如下：
```bash
# 导出FOM模型
需要将 “/ppgan/modules/first_order.py”中的nn.SyncBatchNorm 改为nn.BatchNorm，因为export目前不支持SyncBatchNorm
将 out = out[:, :, ::int_inv_scale, ::int_inv_scale] 改为
out = paddle.fluid.layers.resize_nearest(out, scale=self.scale)
python tools/export_model.py \
--config-file configs/firstorder_vox_mobile_256.yaml \
--load /root/.cache/ppgan/vox_mobile.pdparams \
--inputs_size "1,3,256,256;1,3,256,256;1,10,2;1,10,2,2" \
--export_model output_inference/
```
预测模型会导出到`output_inference/fom_dy2st/`目录下，分别为`model.pdiparams`, `model.pdiparams.info`, `model.pdmodel`。
#### 3.3 PaddleLite部署
- [使用PaddleLite部署FOM模型](./lite/README.md)
- [FOM-Lite-Demo](https://paddlegan.bj.bcebos.com/applications/first_order_model/paddle_lite/apk/face_detection_demo%202.zip)。更多内容，请参考[Paddle-Lite](https://github.com/PaddlePaddle/Paddle-Lite)
目前问题：
(a).paddlelite运行效果略差于inference，正在优化中
(b).单线程跑generator，帧数多了会跑到小核不跑大核
