+```
+deploy/pdserving/
+  └─  det_local_server.py     快速版 检测 服务端
+  └─  det_rpc_server.py       标准版 检测 服务端
+  └─  rec_local_server.py     快速版 识别 服务端

+  └─  ocr_rpc_server.py       标准版 串联 服务端
+  └─  ocr_web_client.py       客户端
+  └─  params.py               配置文件
+```

+## 快速启动服务
+
+<a name="准备环境"></a>
+### 1. 准备环境
+环境版本要求：  
+- **CUDA版本：9.X/10.X**  
+- **CUDNN版本：7.X**  
+- **操作系统版本：Linux/Windows**  
+- **Python版本： 2.7/3.5/3.6/3.7** 
+
+**Python操作指南：**
+
+目前Serving用于OCR的部分功能还在测试当中，因此在这里我们给出[Servnig latest package](https://github.com/PaddlePaddle/Serving/blob/develop/doc/LATEST_PACKAGES.md)
+大家根据自己的环境选择需要安装的whl包即可，例如以Python 3.6为例，执行下列命令：
+```
+# 安装服务端，CPU/GPU版本选择一个
+# GPU版本服务端
+# CUDA 9
+python -m pip install -U https://paddle-serving.bj.bcebos.com/whl/paddle_serving_server_gpu-0.0.0.post9-py3-none-any.whl 
+# CUDA 10
+python -m pip install -U https://paddle-serving.bj.bcebos.com/whl/paddle_serving_server_gpu-0.0.0.post10-py3-none-any.whl
+# CPU版本服务端
+python -m pip install -U https://paddle-serving.bj.bcebos.com/whl/paddle_serving_server-0.0.0-py3-none-any.whl
+
+# 安装客户端和App包，CPU、GPU通用
+python -m pip install -U https://paddle-serving.bj.bcebos.com/whl/paddle_serving_client-0.0.0-cp35-none-any.whl https://paddle-serving.bj.bcebos.com/whl/paddle_serving_app-0.0.0-py3-none-any.whl
+
+# 安装其他依赖
+pip3.6 install func-timeout
+```
+
+<a name="转换模型"></a>
+## 2. 转换模型
+
+Paddle Serving无法直接用训练模型（checkpoints 模型）或推理模型（inference 模型）进行部署。Serving模型由两个文件夹构成，用于存放客户端和服务端的配置。本节介绍如何将推理模型转换为Paddle Serving可部署的模型。
+
+**以文本检测模型`ch_ppocr_mobile_v1.1_det_infer`为例，文本识别模型和方向分类器的转换同理。**
+
+首先下载推理模型：
+```shell
+wget -P ./inference/ https://paddleocr.bj.bcebos.com/20-09-22/mobile/det/ch_ppocr_mobile_v1.1_det_infer.tar && tar xf ./inference/ch_ppocr_mobile_v1.1_det_infer.tar -C ./inference/
+```
+然后运行如下python脚本进行转换，其中，使用参数`model_dir`指定待转换的推理模型路径：
+```
+python deploy/pdserving/inference_to_serving.py --model_dir ./inference/ch_ppocr_mobile_v1.1_det_infer
+```
+最终会在`ch_ppocr_mobile_v1.1_det_infer`目录下生成客户端和服务端的模型配置，结构如下：
+```
+/ch_ppocr_mobile_v1.1_det_infer/
+├── serving_client_dir # 客户端配置文件夹
+└── serving_server_dir # 服务端配置文件夹
+```
+
+<a name="启动服务"></a>
+## 3. 启动服务
+
+启动服务可以根据实际需求选择启动`标准版`或者`快速版`，两种方式的对比如下表：  
+
+|版本|特点|适用场景|
+|-|-|-|
+|标准版|稳定性高，分布式部署|适用于吞吐量大，需要跨机房部署的情况，只能用于Linux平台|
+|快速版|部署方便，预测速度快|适用于对预测速度要求高，迭代速度快的场景，可以支持Linux/Windows|
+
+
+**step 1. 配置环境变量**
+
+```
+# 以下两步的顺序不能反
+export PYTHONPATH=$PWD:$PYTHONPATH
+cd deploy/pdserving
+```
+
+**step 2. 修改配置参数**
+
+配置参数在`params.py`中，具体内容如下所示，可根据需要修改相关参数，如修改模型路径、修改后处理参数等。
+
+```
+def read_params():
+    cfg = Config()
+    #use gpu
+    cfg.use_gpu = False #是否使用GPU，False代表使用CPU
+    cfg.use_pdserving = True  #使用paddle serving部署时必须为True
+
+    #params for text detector
+    cfg.det_algorithm = "DB"
+    cfg.det_server_dir = "../../inference/ch_ppocr_mobile_v1.1_det_infer/serving_server_dir"
+    cfg.det_client_dir = "../../inference/ch_ppocr_mobile_v1.1_det_infer/serving_client_dir"
+    cfg.det_max_side_len = 960
+
+    #DB parmas
+    cfg.det_db_thresh =0.3
+    cfg.det_db_box_thresh =0.5
+    cfg.det_db_unclip_ratio =2.0
+
+    #EAST parmas
+    cfg.det_east_score_thresh = 0.8
+    cfg.det_east_cover_thresh = 0.1
+    cfg.det_east_nms_thresh = 0.2
+
+    #params for text recognizer
+    cfg.rec_algorithm = "CRNN"
+    cfg.rec_server_dir = "../../inference/ch_ppocr_mobile_v1.1_rec_infer/serving_server_dir"
+    cfg.rec_client_dir = "../../inference/ch_ppocr_mobile_v1.1_rec_infer/serving_client_dir"
+
+    cfg.rec_image_shape = "3, 32, 320"
+    cfg.rec_char_type = 'ch'
+    cfg.rec_batch_num = 30
+    cfg.max_text_length = 25
+
+    cfg.rec_char_dict_path = "../../ppocr/utils/ppocr_keys_v1.txt"
+    cfg.use_space_char = True
+
+    #params for text classifier
+    cfg.use_angle_cls = True
+    cfg.cls_server_dir = "../../inference/ch_ppocr_mobile_v1.1_cls_infer/serving_server_dir"
+    cfg.cls_client_dir = "../../inference/ch_ppocr_mobile_v1.1_cls_infer/serving_client_dir"
+    cfg.cls_image_shape = "3, 48, 192"
+    cfg.label_list = ['0', '180']
+    cfg.cls_batch_num = 30
+    cfg.cls_thresh = 0.9
+
+    return cfg
+```
+
+**step 3_1. 启动独立的检测服务或识别服务**
+
+如果只需要搭建检测服务或识别服务，一行命令即可，检测服务的启动方式如下，识别同理。检测+识别的串联服务请直接跳至step 3_2。
+
+```
+# 启动文本检测服务，标准版/快速版 二选一
+python det_rpc_server.py #标准版，Linux用户
+python det_local_server.py #快速版，Windows/Linux用户
+```
+
+**step 3_2. 启动文本检测、识别串联的服务**
+
+如果需要搭建检测+识别的串联服务，快速版与step 3_1中的独立服务启动方式相同，但标准版略有不同，具体步骤如下：
+
+```
+# 标准版，Linux用户
+# GPU用户
+# 启动检测服务
+python -m paddle_serving_server_gpu.serve --model inference/ch_ppocr_mobile_v1.1_det_infer/serving_server_dir/ --port 9293 --gpu_id 0
+# 启动方向分类器服务
+python -m paddle_serving_server_gpu.serve --model inference/ch_ppocr_mobile_v1.1_cls_infer/serving_server_dir/ --port 9294 --gpu_id 0
+# 启动串联服务
+python ocr_rpc_server.py 
+
+# CPU用户
+# 启动检测服务
+python -m paddle_serving_server.serve --model inference/ch_ppocr_mobile_v1.1_det_infer/serving_server_dir/ --port 9293
+# 启动方向分类器服务
+python -m paddle_serving_server.serve --model ch_ppocr_mobile_v1.1_cls_infer/serving_server_dir/ --port 9294
+# 启动串联服务
+python ocr_rpc_server.py
+
+# 快速版，Windows/Linux用户
+python ocr_local_server.py 
+```
+
+<a name="发送预测请求"></a>
+## 发送预测请求
+以上所有单独或串联的服务均可使用如下客户端进行访问：
+```
+python pdserving_client.py image_path
+```
