doc/doc_ch/serving_inference.md

-# 使用Paddle Serving预测推理
-
-阅读本文档之前，请先阅读文档 [基于Python预测引擎推理](./inference.md)
-
-同本地执行预测一样，我们需要保存一份可以用于Paddle Serving的模型。
-
-接下来首先介绍如何将训练的模型转换成Paddle Serving模型，然后将依次介绍文本检测、文本识别以及两者串联基于预测引擎推理。
-
-### 一、 准备环境
-我们先安装Paddle Serving相关组件
-我们推荐用户使用GPU来做Paddle Serving的OCR服务部署
-
-**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_CN.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 3.5为例，执行下列命令
-```
-#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
-#客户端和App包使用以下链接（CPU，GPU通用）
-python -m pip install -U https://paddle-serving.bj.bcebos.com/whl/paddle_serving_client-0.0.0-cp36-none-any.whl https://paddle-serving.bj.bcebos.com/whl/paddle_serving_app-0.0.0-py3-none-any.whl
-```
-
-## 二、训练模型转Serving模型
-
-在前序文档 [基于Python预测引擎推理](./inference.md) 中，我们提供了如何把训练的checkpoint转换成Paddle模型。Paddle模型通常由一个文件夹构成，内含模型结构描述文件`model`和模型参数文件`params`。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。
-
-我们以`ch_rec_r34_vd_crnn`模型作为例子，下载链接在：
-
-```
-wget --no-check-certificate https://paddleocr.bj.bcebos.com/ch_models/ch_rec_r34_vd_crnn_infer.tar
-tar xf ch_rec_r34_vd_crnn_infer.tar
-```
-因此我们按照Serving模型转换教程，运行下列python文件。
-```
-python tools/inference_to_serving.py --model_dir ch_rec_r34_vd_crnn
-```
-最终会在`serving_client_dir`和`serving_server_dir`生成客户端和服务端的模型配置。其中`serving_server_dir`和`serving_client_dir`的名字可以自定义。最终文件结构如下
-
-```
-/ch_rec_r34_vd_crnn/
-├── serving_client_dir # 客户端配置文件夹
-└── serving_server_dir # 服务端配置文件夹
-```
-
-## 三、文本检测模型Serving推理
-
-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|
-|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，Windows用户只能选择快速版|
-
-接下来的命令中，我们会指定快速版和标准版的命令。需要说明的是，标准版只能用Linux平台，快速版可以支持Linux/Windows。
-文本检测模型推理，默认使用DB模型的配置参数，识别默认为CRNN。
-
-配置文件在`params.py`中，我们贴出配置部分，如果需要做改动，也在这个文件内部进行修改。
-
-```
-def read_params():
-    cfg = Config()
-    #use gpu
-    cfg.use_gpu = False # 是否使用GPU
-    cfg.use_pdserving = True # 是否使用paddleserving，必须为True
-
-    #params for text detector
-    cfg.det_algorithm = "DB" # 检测算法， DB/EAST等
-    cfg.det_model_dir = "./det_mv_server/" # 检测算法模型路径
-    cfg.det_max_side_len = 960
-
-    #DB params
-    cfg.det_db_thresh =0.3
-    cfg.det_db_box_thresh =0.5
-    cfg.det_db_unclip_ratio =2.0
-
-    #EAST params
-    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" # 识别算法， CRNN/RARE等
-    cfg.rec_model_dir = "./ocr_rec_server/" # 识别算法模型路径
-
-    cfg.rec_image_shape = "3, 32, 320"
-    cfg.rec_batch_num = 30
-    cfg.max_text_length = 25
-
-    cfg.rec_char_dict_path = "./ppocr_keys_v1.txt" # 识别算法字典文件
-    cfg.use_space_char = True
-
-    #params for text classifier
-    cfg.use_angle_cls = True # 是否启用分类算法
-    cfg.cls_model_dir = "./ocr_clas_server/" # 分类算法模型路径
-    cfg.cls_image_shape = "3, 48, 192"
-    cfg.label_list = ['0', '180']
-    cfg.cls_batch_num = 30
-    cfg.cls_thresh = 0.9
-
-    return cfg
-```
-与本地预测不同的是，Serving预测需要一个客户端和一个服务端，因此接下来的教程都是两行代码。
-
-在正式执行服务端启动命令之前，先export PYTHONPATH到工程主目录下。
-```
-export PYTHONPATH=$PWD:$PYTHONPATH
-cd deploy/pdserving
-```
-为了方便用户复现Demo程序，我们提供了Chinese and English ultra-lightweight OCR model (8.1M)版本的Serving模型
-```
-wget --no-check-certificate https://paddleocr.bj.bcebos.com/deploy/pdserving/ocr_pdserving_suite.tar.gz
-tar xf ocr_pdserving_suite.tar.gz
-```
-
-### 1. 超轻量中文检测模型推理
-
-超轻量中文检测模型推理，可以执行如下命令启动服务端：
-
-```
-#根据环境只需要启动其中一个就可以
-python det_rpc_server.py #标准版，Linux用户
-python det_local_server.py #快速版，Windows/Linux用户
-```
-
-客户端
-
-```
-python det_web_client.py
-```
-
-
-Serving的推测和本地预测不同点在于，客户端发送请求到服务端，服务端需要检测到文字框之后返回框的坐标，此处没有后处理的图片，只能看到坐标值。
-
-## 四、文本识别模型Serving推理
-
-下面将介绍超轻量中文识别模型推理、基于CTC损失的识别模型推理和基于Attention损失的识别模型推理。对于中文文本识别，建议优先选择基于CTC损失的识别模型，实践中也发现基于Attention损失的效果不如基于CTC损失的识别模型。此外，如果训练时修改了文本的字典，请参考下面的自定义文本识别字典的推理。
-
-### 1. 超轻量中文识别模型推理
-
-超轻量中文识别模型推理，可以执行如下命令启动服务端：
-需要注意params.py中的`--use_gpu`的值
-```
-#根据环境只需要启动其中一个就可以
-python rec_rpc_server.py #标准版，Linux用户
-python rec_local_server.py #快速版，Windows/Linux用户
-```
-如果需要使用CPU版本，还需增加 `--use_gpu False`。
-
-客户端
-
-```
-python rec_web_client.py
-```
-
-![](../imgs_words/ch/word_4.jpg)
-
-执行命令后，上面图像的预测结果（识别的文本和得分）会打印到屏幕上，示例如下：
-
-```
-{u'result': {u'score': [u'0.89547354'], u'pred_text': ['实力活力']}}
-```
-
-
-
-## 五、方向分类模型推理
-
-下面将介绍方向分类模型推理。
-
-
-
-### 1. 方向分类模型推理
-
-方向分类模型推理， 可以执行如下命令启动服务端：
-需要注意params.py中的`--use_gpu`的值
-```
-#根据环境只需要启动其中一个就可以
-python clas_rpc_server.py #标准版，Linux用户
-python clas_local_server.py #快速版，Windows/Linux用户
-```
-
-客户端
-
-```
-python rec_web_client.py
-```
-
-![](../imgs_words/ch/word_4.jpg)
-
-执行命令后，上面图像的预测结果（分类的方向和得分）会打印到屏幕上，示例如下：
-
-```
-{u'result': {u'direction': [u'0'], u'score': [u'0.9999963']}}
-```
-
-
-## 六、文本检测、方向分类和文字识别串联Serving推理
-
-### 1. 超轻量中文OCR模型推理
-
-在执行预测时，需要通过参数`image_dir`指定单张图像或者图像集合的路径、参数`det_model_dir`,`cls_model_dir`和`rec_model_dir`分别指定检测，方向分类和识别的inference模型路径。参数`use_angle_cls`用于控制是否启用方向分类模型。与本地预测不同的是，为了减少网络传输耗时，可视化识别结果目前不做处理，用户收到的是推理得到的文字字段。
-
-执行如下命令启动服务端：
-需要注意params.py中的`--use_gpu`的值
-```
-#标准版，Linux用户
-#GPU用户
-python -m paddle_serving_server_gpu.serve --model det_infer_server --port 9293 --gpu_id 0
-python -m paddle_serving_server_gpu.serve --model cls_infer_server --port 9294 --gpu_id 0
-python ocr_rpc_server.py
-#CPU用户
-python -m paddle_serving_server.serve --model det_infer_server --port 9293
-python -m paddle_serving_server.serve --model cls_infer_server --port 9294
-python ocr_rpc_server.py
-
-#快速版，Windows/Linux用户
-python ocr_local_server.py
-```
-
-客户端
-
-```
-python rec_web_client.py
-```
