## 1. 简介
[Paddle Serving](https://github.com/PaddlePaddle/Serving) 旨在帮助深度学习开发者轻松部署在线预测服务,支持一键部署工业级的服务能力、客户端和服务端之间高并发和高效通信、并支持多种编程语言开发客户端。
该部分以 HTTP 预测服务部署为例,介绍怎样在 PaddleClas 中使用 PaddleServing 部署模型服务。

## 2. Serving安装

## 3. 导出模型
使用 `tools/export_serving_model.py` 脚本导出 Serving 模型,以 `ResNet50_vd` 为例,使用方法如下
<a name="图像分类服务部署"></a>
## 3. 图像分类服务部署
### 3.1 模型转换
使用PaddleServing做服务化部署时,需要将保存的inference模型转换为Serving模型。下面以经典的ResNet50_vd模型为例,介绍如何部署图像分类服务
- 进入工作目录:
```shell
python tools/export_serving_model.py -m ResNet50_vd -p ./pretrained/ResNet50_vd_pretrained/ -o serving
cd deploy/paddleserving
```
- 下载ResNet50_vd的inference模型:
```shell
# 下载并解压ResNet50_vd模型
wget https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/inference/ResNet50_vd_infer.tar && tar xf ResNet50_vd_infer.tar
```
- 用paddle_serving_client把下载的inference模型转换成易于Server部署的模型格式:
```
# 转换ResNet50_vd模型
python3 -m paddle_serving_client.convert --dirname ./ResNet50_vd_infer/ \
--model_filename inference.pdmodel \
--params_filename inference.pdiparams \
--serving_server ./ResNet50_vd_serving/ \
--serving_client ./ResNet50_vd_client/
```
ResNet50_vd推理模型转换完成后,会在当前文件夹多出`ResNet50_vd_serving``ResNet50_vd_client`的文件夹,具备如下格式:
```
|- ResNet50_vd_client/
|- __model__
|- __params__
|- serving_server_conf.prototxt
|- serving_server_conf.stream.prototxt
|- ResNet50_vd_client
|- serving_client_conf.prototxt
|- serving_client_conf.stream.prototxt
```
得到模型文件之后,需要修改serving_server_conf.prototxt中的alias名字: 将`feed_var`中的`alias_name`改为`image`, 将`fetch_var`中的`alias_name`改为`prediction`
最终在 serving 文件夹下会生成 `ppcls_client_conf``ppcls_model` 两个文件夹,分别存储了 client 配置、模型参数与结构文件。
**备注**: Serving为了兼容不同模型的部署,提供了输入输出重命名的功能。这样,不同的模型在推理部署时,只需要修改配置文件的alias_name即可,无需修改代码即可完成推理部署。
修改后的serving_server_conf.prototxt如下所示:
```
feed_var {
name: "inputs"
alias_name: "image"
is_lod_tensor: false
feed_type: 1
shape: 3
shape: 224
shape: 224
}
fetch_var {
name: "save_infer_model/scale_0.tmp_1"
alias_name: "prediction"
is_lod_tensor: true
fetch_type: 1
shape: -1
}
```
### 3.2 服务部署和请求
paddleserving目录包含了启动pipeline服务和发送预测请求的代码,包括:
```shell
__init__.py
config.yml # 启动服务的配置文件
pipeline_http_client.py # http方式发送pipeline预测请求的脚本
pipeline_rpc_client.py # rpc方式发送pipeline预测请求的脚本
classification_web_service.py # 启动pipeline服务端的脚本
```
- 启动服务:
```shell
# 启动服务,运行日志保存在log.txt
python3 classification_web_service.py &>log.txt &
```
成功启动服务后,log.txt中会打印类似如下日志
![](../../../deploy/paddleserving/imgs/start_server.png)
## 4. 服务部署与请求
- 发送请求:
```shell
# 发送服务请求
python3 pipeline_http_client.py
```
成功运行后,模型预测的结果会打印在cmd窗口中,结果示例为:
![](../../../deploy/paddleserving/imgs/results.png)
<a name="图像识别服务部署"></a>
## 4.图像识别服务部署
使用PaddleServing做服务化部署时,需要将保存的inference模型转换为Serving模型。 下面以PP-ShiTu中的超轻量图像识别模型为例,介绍图像识别服务的部署。
## 4.1 模型转换
- 下载通用检测inference模型和通用识别inference模型
```
cd deploy
# 下载并解压通用识别模型
wget -P models/ https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/models/inference/general_PPLCNet_x2_5_lite_v1.0_infer.tar
cd models
tar -xf general_PPLCNet_x2_5_lite_v1.0_infer.tar
# 下载并解压通用检测模型
wget https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/models/inference/picodet_PPLCNet_x2_5_mainbody_lite_v1.0_infer.tar
tar -xf picodet_PPLCNet_x2_5_mainbody_lite_v1.0_infer.tar
```
- 转换识别inference模型为Serving模型:
```
# 转换识别模型
python3 -m paddle_serving_client.convert --dirname ./general_PPLCNet_x2_5_lite_v1.0_infer/ \
--model_filename inference.pdmodel \
--params_filename inference.pdiparams \
--serving_server ./general_PPLCNet_x2_5_lite_v1.0_serving/ \
--serving_client ./general_PPLCNet_x2_5_lite_v1.0_client/
```
识别推理模型转换完成后,会在当前文件夹多出`general_PPLCNet_x2_5_lite_v1.0_serving/``general_PPLCNet_x2_5_lite_v1.0_serving/`的文件夹。修改`general_PPLCNet_x2_5_lite_v1.0_serving/`目录下的serving_server_conf.prototxt中的alias名字: 将`fetch_var`中的`alias_name`改为`features`
修改后的serving_server_conf.prototxt内容如下:
```
feed_var {
name: "x"
alias_name: "x"
is_lod_tensor: false
feed_type: 1
shape: 3
shape: 224
shape: 224
}
fetch_var {
name: "save_infer_model/scale_0.tmp_1"
alias_name: "features"
is_lod_tensor: true
fetch_type: 1
shape: -1
}
```
- 转换通用检测inference模型为Serving模型:
```
# 转换通用检测模型
python3 -m paddle_serving_client.convert --dirname ./picodet_PPLCNet_x2_5_mainbody_lite_v1.0_infer/ \
--model_filename inference.pdmodel \
--params_filename inference.pdiparams \
--serving_server ./picodet_PPLCNet_x2_5_mainbody_lite_v1.0_serving/ \
--serving_client ./picodet_PPLCNet_x2_5_mainbody_lite_v1.0_client/
```
检测inference模型转换完成后,会在当前文件夹多出`picodet_PPLCNet_x2_5_mainbody_lite_v1.0_serving/``picodet_PPLCNet_x2_5_mainbody_lite_v1.0_client/`的文件夹。
* 使用下面的方式启动 Serving 服务
**注意:** 此处不需要修改`picodet_PPLCNet_x2_5_mainbody_lite_v1.0_serving/`目录下的serving_server_conf.prototxt中的alias名字
- 下载并解压已经构建后的检索库index
```
cd ../
wget https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/data/drink_dataset_v1.0.tar && tar -xf drink_dataset_v1.0.tar
```
## 4.2 服务部署和请求
**注意:** 识别服务涉及到多个模型,出于性能考虑采用PipeLine部署方式。Pipeline部署方式当前不支持windows平台。
- 进入到工作目录
```shell
python tools/serving/image_service_gpu.py serving/ppcls_model workdir 9292
cd ./deploy/paddleserving/recognition
```
paddleserving目录包含启动pipeline服务和发送预测请求的代码,包括:
```
__init__.py
config.yml # 启动服务的配置文件
pipeline_http_client.py # http方式发送pipeline预测请求的脚本
pipeline_rpc_client.py # rpc方式发送pipeline预测请求的脚本
recognition_web_service.py # 启动pipeline服务端的脚本
```
- 启动服务:
```
# 启动服务,运行日志保存在log.txt
python3 recognition_web_service.py &>log.txt &
```
成功启动服务后,log.txt中会打印类似如下日志
![](../../../deploy/paddleserving/imgs/start_server_shitu.png)
其中 `serving/ppcls_model` 为刚才保存的 Serving 模型地址,`workdir` 为工作目录,`9292` 为服务的端口号。
- 发送请求:
```
python3 pipeline_http_client.py
```
成功运行后,模型预测的结果会打印在cmd窗口中,结果示例为:
![](../../../deploy/paddleserving/imgs/results_shitu.png)
* 使用下面的脚本向 Serving 服务发送识别请求,并返回结果。
<a name="FAQ"></a>
## 5.FAQ
**Q1**: 发送请求后没有结果返回或者提示输出解码报错
**A1**: 启动服务和发送请求时不要设置代理,可以在启动服务前和发送请求前关闭代理,关闭代理的命令是:
```
python tools/serving/image_http_client.py 9292 ./docs/images/logo.png
unset https_proxy
unset http_proxy
```
`9292` 为发送请求的端口号,需要与服务启动时的端口号保持一致,`./docs/images/logo.png` 为待识别的图像文件。最终返回 Top1 识别结果的类别 ID 以及概率值。
* 更多的服务部署类型,如 `RPC预测服务` 等,可以参考 Serving 的 github 官网:[https://github.com/PaddlePaddle/Serving/tree/develop/python/examples/imagenet](https://github.com/PaddlePaddle/Serving/tree/develop/python/examples/imagenet)
