+# PaddleClas 服务化部署
+
+([English](./README.md)|简体中文)
+
+PaddleClas提供2种服务部署方式：
+- 基于PaddleHub Serving的部署：代码路径为"`./deploy/hubserving`"，使用方法参考[文档](../../deploy/hubserving/readme.md)；
+- 基于PaddleServing的部署：代码路径为"`./deploy/paddleserving`"，按照本教程使用。
+
+# 基于PaddleServing的服务部署
+
+本文档以经典的ResNet50_vd模型为例，介绍如何使用[PaddleServing](https://github.com/PaddlePaddle/Serving/blob/develop/README_CN.md)工具部署PaddleClas
+动态图模型的pipeline在线服务。
+
+相比较于hubserving部署，PaddleServing具备以下优点：
+- 支持客户端和服务端之间高并发和高效通信
+- 支持 工业级的服务能力 例如模型管理，在线加载，在线A/B测试等
+- 支持 多种编程语言 开发客户端，例如C++, Python和Java
+
+更多有关PaddleServing服务化部署框架介绍和使用教程参考[文档](https://github.com/PaddlePaddle/Serving/blob/develop/README_CN.md)。

+## 环境准备
+
+需要准备PaddleClas的运行环境和Paddle Serving的运行环境。
+
+- 准备PaddleOCR的运行环境[链接](../../doc/doc_ch/installation.md)
+  根据环境下载对应的paddle whl包，推荐安装2.0.1版本
+
+- 准备PaddleServing的运行环境，步骤如下
+
+1. 安装serving，用于启动服务
+    ```
+    pip3 install paddle-serving-server==0.6.1 # for CPU
+    pip3 install paddle-serving-server-gpu==0.6.1 # for GPU
+    # 其他GPU环境需要确认环境再选择执行如下命令
+    pip3 install paddle-serving-server-gpu==0.6.1.post101 # GPU with CUDA10.1 + TensorRT6
+    pip3 install paddle-serving-server-gpu==0.6.1.post11 # GPU with CUDA11 + TensorRT7
+    ```
+
+2. 安装client，用于向服务发送请求
+    在[下载链接](https://github.com/PaddlePaddle/Serving/blob/develop/doc/LATEST_PACKAGES.md)中找到对应python版本的client安装包，这里推荐python3.7版本：
+
+    ```
+    wget https://paddle-serving.bj.bcebos.com/test-dev/whl/paddle_serving_client-0.0.0-cp37-none-any.whl
+    pip3 install paddle_serving_client-0.0.0-cp37-none-any.whl
+    ```
+
+3. 安装serving-app
+    ```
+    pip3 install paddle-serving-app==0.6.1
+    ```
+    **Note:** 如果要安装最新版本的PaddleServing参考[链接](https://github.com/PaddlePaddle/Serving/blob/develop/doc/LATEST_PACKAGES.md)。
+
+<a name="模型转换"></a>
+## 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易于部署的模型。
+
+首先，下载ResNet50_vd的[inference模型](https://github.com/PaddlePaddle/PaddleOCR#pp-ocr-20-series-model-listupdate-on-dec-15)
+```
+# 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
+```
+
+接下来，用安装的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 ./inference/ \
+                                         --model_filename inference.pdmodel  \        \
+                                         --params_filename inference.pdiparams \       \
+                                         --serving_server ./ResNet50_vd_serving/ \
+                                         --serving_client ./ResNet50_vd_client/
+```
+检测模型转换完成后，会在当前文件夹多出`ResNet50_vd_serving` 和`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
+
+```
+
+<a name="部署"></a>
+## Paddle Serving pipeline部署
+
+1. 下载PaddleClas代码，若已下载可跳过此步骤
+    ```
+    git clone https://github.com/PaddlePaddle/PaddleClas
+
+    # 进入到工作目录
+    cd PaddleOCR/deploy/paddleserving/
+    ```
+    pdserver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
+    resnet50_web_service.py    # 启动pipeline服务端的脚本
+    ```
+
+2. 启动服务可运行如下命令：
+    ```
+    # 启动服务，运行日志保存在log.txt
+    python3 resnet50_web_service.py &>log.txt &
+    ```
+    成功启动服务后，log.txt中会打印类似如下日志
+    ![](./imgs/start_server.png)
+
+3. 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：
+    ![](./imgs/results.png)
+
+    调整 config.yml 中的并发个数获得最大的QPS, 一般检测和识别的并发数为2：1
+    ```
+    op:
+        #并发数，is_thread_op=True时，为线程并发；否则为进程并发
+        concurrency: 8
+        ...
+    有需要的话可以同时发送多个服务请求
+
+    预测性能数据会被自动写入 `PipelineServingLogs/pipeline.tracer` 文件中。
+
+<a name="FAQ"></a>
+## 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：
+```
+unset https_proxy
+unset http_proxy
+```

deploy/paddleserving/config.yml

+#worker_num, 最大并发数。当build_dag_each_worker=True时, 框架会创建worker_num个进程，每个进程内构建grpcSever和DAG
+##当build_dag_each_worker=False时，框架会设置主线程grpc线程池的max_workers=worker_num
+worker_num: 1
+
+#http端口, rpc_port和http_port不允许同时为空。当rpc_port可用且http_port为空时，不自动生成http_port
+http_port: 18080
+rpc_port: 9993
+

+    #op资源类型, True, 为线程模型；False，为进程模型
