+
+PaddleOCR提供2种服务部署方式：
+- 基于PaddleHub Serving的部署：代码路径为"`./deploy/hubserving`"，按照本教程使用；
+- 基于PaddleServing的部署：代码路径为"`./deploy/pdserving`"，使用方法参考[文档](../../deploy/pdserving/readme.md)。
+
+# 基于PaddleHub Serving的服务部署
+
+hubserving服务部署目录下包括检测、识别、2阶段串联三种服务包，请根据需求选择相应的服务包进行安装和启动。目录结构如下：
+```
+deploy/hubserving/
+ └─ ocr_cls 分类模块服务包
+ └─ ocr_det 检测模块服务包
+ └─ ocr_rec 识别模块服务包
+ └─ ocr_system 检测+识别串联服务包
+```
+
+每个服务包下包含3个文件。以2阶段串联服务包为例，目录如下：
+```
+deploy/hubserving/ocr_system/
+ └─ __init__.py 空文件，必选
+ └─ config.json 配置文件，可选，使用配置启动服务时作为参数传入
+ └─ module.py 主模块，必选，包含服务的完整逻辑
+ └─ params.py 参数文件，必选，包含模型路径、前后处理参数等参数
+```
+
+## 快速启动服务
+以下步骤以检测+识别2阶段串联服务为例，如果只需要检测服务或识别服务，替换相应文件路径即可。
+### 1. 准备环境
+```shell
+# 安装paddlehub
+pip3 install paddlehub --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+### 2. 下载推理模型
+安装服务模块前，需要准备推理模型并放到正确路径。默认使用的是v1.1版的超轻量模型，默认模型路径为：
+```
+检测模型：./inference/ch_ppocr_mobile_v1.1_det_infer/
+识别模型：./inference/ch_ppocr_mobile_v1.1_rec_infer/
+方向分类器：./inference/ch_ppocr_mobile_v1.1_cls_infer/
+```
+
+**模型路径可在`params.py`中查看和修改。** 更多模型可以从PaddleOCR提供的[模型库](../../doc/doc_ch/models_list.md)下载，也可以替换成自己训练转换好的模型。
+
+### 3. 安装服务模块
+PaddleOCR提供3种服务模块，根据需要安装所需模块。
+
+* 在Linux环境下，安装示例如下：
+```shell
+# 安装检测服务模块：
+hub install deploy/hubserving/ocr_det/
+
+# 或，安装分类服务模块：
+hub install deploy/hubserving/ocr_cls/
+
+# 或，安装识别服务模块：
+hub install deploy/hubserving/ocr_rec/
+
+# 或，安装检测+识别串联服务模块：
+hub install deploy/hubserving/ocr_system/
+```
+
+* 在Windows环境下(文件夹的分隔符为`\`)，安装示例如下：
+```shell
+# 安装检测服务模块：
+hub install deploy\hubserving\ocr_det\
+
+# 或，安装分类服务模块：
+hub install deploy\hubserving\ocr_cls\
+
+# 或，安装识别服务模块：
+hub install deploy\hubserving\ocr_rec\
+
+# 或，安装检测+识别串联服务模块：
+hub install deploy\hubserving\ocr_system\
+```
+
+### 4. 启动服务
+#### 方式1. 命令行命令启动（仅支持CPU）
+**启动命令：**
+```shell
+$ hub serving start --modules [Module1==Version1, Module2==Version2, ...] \
+ --port XXXX \
+ --use_multiprocess \
+ --workers \
+```
+
+**参数：**
+
+|参数|用途|
+|-|-|
+|--modules/-m|PaddleHub Serving预安装模型，以多个Module==Version键值对的形式列出
*`当不指定Version时，默认选择最新版本`*|
+|--port/-p|服务端口，默认为8866|
+|--use_multiprocess|是否启用并发方式，默认为单进程方式，推荐多核CPU机器使用此方式
*`Windows操作系统只支持单进程方式`*|
+|--workers|在并发方式下指定的并发任务数，默认为`2*cpu_count-1`，其中`cpu_count`为CPU核数|
+
+如启动串联服务： ```hub serving start -m ocr_system```
+
+这样就完成了一个服务化API的部署，使用默认端口号8866。
+
+#### 方式2. 配置文件启动（支持CPU、GPU）
+**启动命令：**
+```hub serving start -c config.json```
+
+其中，`config.json`格式如下：
+```python
+{
+ "modules_info": {
+ "ocr_system": {
+ "init_args": {
+ "version": "1.0.0",
+ "use_gpu": true
+ },
+ "predict_args": {
+ }
+ }
+ },
+ "port": 8868,
+ "use_multiprocess": false,
+ "workers": 2
+}
+```
+
+- `init_args`中的可配参数与`module.py`中的`_initialize`函数接口一致。其中，**当`use_gpu`为`true`时，表示使用GPU启动服务**。
+- `predict_args`中的可配参数与`module.py`中的`predict`函数接口一致。
+
+**注意:**
+- 使用配置文件启动服务时，其他参数会被忽略。
+- 如果使用GPU预测(即，`use_gpu`置为`true`)，则需要在启动服务之前，设置CUDA_VISIBLE_DEVICES环境变量，如：```export CUDA_VISIBLE_DEVICES=0```，否则不用设置。
+- **`use_gpu`不可与`use_multiprocess`同时为`true`**。
+
+如，使用GPU 3号卡启动串联服务：
+```shell
+export CUDA_VISIBLE_DEVICES=3
+hub serving start -c deploy/hubserving/ocr_system/config.json
+```
+
+## 发送预测请求
+配置好服务端，可使用以下命令发送预测请求，获取预测结果:
+
+```python tools/test_hubserving.py server_url image_path```
+
+需要给脚本传递2个参数：
+- **server_url**：服务地址，格式为
+`http://[ip_address]:[port]/predict/[module_name]`
+例如，如果使用配置文件启动分类，检测、识别，检测+分类+识别3阶段服务，那么发送请求的url将分别是：
+`http://127.0.0.1:8865/predict/ocr_det`
+`http://127.0.0.1:8866/predict/ocr_cls`
+`http://127.0.0.1:8867/predict/ocr_rec`
+`http://127.0.0.1:8868/predict/ocr_system`
+- **image_path**：测试图像路径，可以是单张图片路径，也可以是图像集合目录路径
+
+访问示例：
+```python tools/test_hubserving.py http://127.0.0.1:8868/predict/ocr_system ./doc/imgs/```
+
+## 返回结果格式说明
+返回结果为列表（list），列表中的每一项为词典（dict），词典一共可能包含3种字段，信息如下：
+
+|字段名称|数据类型|意义|
+|----|----|----|
+|angle|str|文本角度|
+|text|str|文本内容|
+|confidence|float| 文本识别置信度或文本角度分类置信度|
+|text_region|list|文本位置坐标|
+
+不同模块返回的字段不同，如，文本识别服务模块返回结果不含`text_region`字段，具体信息如下：
+
+| 字段名/模块名 | ocr_det | ocr_cls | ocr_rec | ocr_system |
+| ---- | ---- | ---- | ---- | ---- |
+|angle| | ✔ | | ✔ |
+|text| | |✔|✔|
+|confidence| |✔ |✔|✔|
+|text_region| ✔| | |✔ |
+
+**说明：** 如果需要增加、删除、修改返回字段，可在相应模块的`module.py`文件中进行修改，完整流程参考下一节自定义修改服务模块。
+
+## 自定义修改服务模块
+如果需要修改服务逻辑，你一般需要操作以下步骤（以修改`ocr_system`为例）：
+
+- 1、 停止服务
+```hub serving stop --port/-p XXXX```
+
+- 2、 到相应的`module.py`和`params.py`等文件中根据实际需求修改代码。
+例如，如果需要替换部署服务所用模型，则需要到`params.py`中修改模型路径参数`det_model_dir`和`rec_model_dir`，如果需要关闭文本方向分类器，则将参数`use_angle_cls`置为`False`，当然，同时可能还需要修改其他相关参数，请根据实际情况修改调试。 **强烈建议修改后先直接运行`module.py`调试，能正确运行预测后再启动服务测试。**
+
+- 3、 卸载旧服务包
+```hub uninstall ocr_system```
+
+- 4、 安装修改后的新服务包
+```hub install deploy/hubserving/ocr_system/```
+
+- 5、重新启动服务
+```hub serving start -m ocr_system```

+
+PaddleOCR provides 2 service deployment methods:
+- Based on **PaddleHub Serving**: Code path is "`./deploy/hubserving`". Please follow this tutorial.
+- Based on **PaddleServing**: Code path is "`./deploy/pdserving`". Please refer to the [tutorial](../../deploy/pdserving/readme.md) for usage.
+
+# Service deployment based on PaddleHub Serving
+
+The hubserving service deployment directory includes three service packages: detection, recognition, and two-stage series connection. Please select the corresponding service package to install and start service according to your needs. The directory is as follows:
+```
+deploy/hubserving/
+ └─ ocr_det detection module service package
+ └─ ocr_cls angle class module service package
+ └─ ocr_rec recognition module service package
+ └─ ocr_system two-stage series connection service package
+```
+
+Each service pack contains 3 files. Take the 2-stage series connection service package as an example, the directory is as follows:
+```
+deploy/hubserving/ocr_system/
+ └─ __init__.py Empty file, required
+ └─ config.json Configuration file, optional, passed in as a parameter when using configuration to start the service
+ └─ module.py Main module file, required, contains the complete logic of the service
+ └─ params.py Parameter file, required, including parameters such as model path, pre- and post-processing parameters
+```
+
+## Quick start service
+The following steps take the 2-stage series service as an example. If only the detection service or recognition service is needed, replace the corresponding file path.
+
+### 1. Prepare the environment
+```shell
+# Install paddlehub
+pip3 install paddlehub --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+### 2. Download inference model
+Before installing the service module, you need to prepare the inference model and put it in the correct path. By default, the ultra lightweight model of v1.1 is used, and the default model path is:
+```
+detection model: ./inference/ch_ppocr_mobile_v1.1_det_infer/
+recognition model: ./inference/ch_ppocr_mobile_v1.1_rec_infer/
+text direction classifier: ./inference/ch_ppocr_mobile_v1.1_cls_infer/
+```
+
+**The model path can be found and modified in `params.py`.** More models provided by PaddleOCR can be obtained from the [model library](../../doc/doc_en/models_list_en.md). You can also use models trained by yourself.
+
+### 3. Install Service Module
+PaddleOCR provides 3 kinds of service modules, install the required modules according to your needs.
+
+* On Linux platform, the examples are as follows.
+```shell
+# Install the detection service module:
+hub install deploy/hubserving/ocr_det/
+
+# Or, install the angle class service module:
+hub install deploy/hubserving/ocr_cls/
+
+# Or, install the recognition service module:
+hub install deploy/hubserving/ocr_rec/
+
+# Or, install the 2-stage series service module:
+hub install deploy/hubserving/ocr_system/
+```
+
+* On Windows platform, the examples are as follows.
+```shell
+# Install the detection service module:
+hub install deploy\hubserving\ocr_det\
+
+# Or, install the angle class service module:
+hub install deploy\hubserving\ocr_cls\
+
+# Or, install the recognition service module:
+hub install deploy\hubserving\ocr_rec\
+
+# Or, install the 2-stage series service module:
+hub install deploy\hubserving\ocr_system\
+```
+
+### 4. Start service
+#### Way 1. Start with command line parameters (CPU only)
+
+**start command：**
+```shell
+$ hub serving start --modules [Module1==Version1, Module2==Version2, ...] \
+ --port XXXX \
+ --use_multiprocess \
+ --workers \
+```
+**parameters：**
+
+|parameters|usage|
+|-|-|
+|--modules/-m|PaddleHub Serving pre-installed model, listed in the form of multiple Module==Version key-value pairs
*`When Version is not specified, the latest version is selected by default`*|
+|--port/-p|Service port, default is 8866|
+|--use_multiprocess|Enable concurrent mode, the default is single-process mode, this mode is recommended for multi-core CPU machines
*`Windows operating system only supports single-process mode`*|
+|--workers|The number of concurrent tasks specified in concurrent mode, the default is `2*cpu_count-1`, where `cpu_count` is the number of CPU cores|
+
+For example, start the 2-stage series service:
+```shell
+hub serving start -m ocr_system
+```
+
+This completes the deployment of a service API, using the default port number 8866.
+
+#### Way 2. Start with configuration file（CPU、GPU）
+**start command：**
+```shell
+hub serving start --config/-c config.json
+```
+Wherein, the format of `config.json` is as follows:
+```python
+{
+ "modules_info": {
+ "ocr_system": {
+ "init_args": {
+ "version": "1.0.0",
+ "use_gpu": true
+ },
+ "predict_args": {
+ }
+ }
+ },
+ "port": 8868,
+ "use_multiprocess": false,
+ "workers": 2
+}
+```
+- The configurable parameters in `init_args` are consistent with the `_initialize` function interface in `module.py`. Among them, **when `use_gpu` is `true`, it means that the GPU is used to start the service**.
+- The configurable parameters in `predict_args` are consistent with the `predict` function interface in `module.py`.
+
+**Note:**
+- When using the configuration file to start the service, other parameters will be ignored.
+- If you use GPU prediction (that is, `use_gpu` is set to `true`), you need to set the environment variable CUDA_VISIBLE_DEVICES before starting the service, such as: ```export CUDA_VISIBLE_DEVICES=0```, otherwise you do not need to set it.
+- **`use_gpu` and `use_multiprocess` cannot be `true` at the same time.**
+
+For example, use GPU card No. 3 to start the 2-stage series service:
+```shell
+export CUDA_VISIBLE_DEVICES=3
+hub serving start -c deploy/hubserving/ocr_system/config.json
+```
+
+## Send prediction requests
+After the service starts, you can use the following command to send a prediction request to obtain the prediction result:
+```shell
+python tools/test_hubserving.py server_url image_path
+```
+
+Two parameters need to be passed to the script:
+- **server_url**：service address，format of which is
+`http://[ip_address]:[port]/predict/[module_name]`
+For example, if the detection, recognition and 2-stage serial services are started with provided configuration files, the respective `server_url` would be:
+`http://127.0.0.1:8865/predict/ocr_det`
+`http://127.0.0.1:8866/predict/ocr_cls`
+`http://127.0.0.1:8867/predict/ocr_rec`
+`http://127.0.0.1:8868/predict/ocr_system`
+- **image_path**：Test image path, can be a single image path or an image directory path
+
+**Eg.**
+```shell
+python tools/test_hubserving.py http://127.0.0.1:8868/predict/ocr_system ./doc/imgs/
+```
+
+## Returned result format
+The returned result is a list. Each item in the list is a dict. The dict may contain three fields. The information is as follows:
+
+|field name|data type|description|
+|----|----|----|
+|angle|str|angle|
+|text|str|text content|
+|confidence|float|text recognition confidence|
+|text_region|list|text location coordinates|
+
+The fields returned by different modules are different. For example, the results returned by the text recognition service module do not contain `text_region`. The details are as follows:
+
+| field name/module name | ocr_det | ocr_cls | ocr_rec | ocr_system |
+| ---- | ---- | ---- | ---- | ---- |
+|angle| | ✔ | | ✔ |
+|text| | |✔|✔|
+|confidence| |✔ |✔|✔|
+|text_region| ✔| | |✔ |
+
+**Note：** If you need to add, delete or modify the returned fields, you can modify the file `module.py` of the corresponding module. For the complete process, refer to the user-defined modification service module in the next section.
+
+## User defined service module modification
+If you need to modify the service logic, the following steps are generally required (take the modification of `ocr_system` for example):
+
+- 1. Stop service
+```shell
+hub serving stop --port/-p XXXX
+```
+- 2. Modify the code in the corresponding files, like `module.py` and `params.py`, according to the actual needs.
+For example, if you need to replace the model used by the deployed service, you need to modify model path parameters `det_model_dir` and `rec_model_dir` in `params.py`. If you want to turn off the text direction classifier, set the parameter `use_angle_cls` to `False`. Of course, other related parameters may need to be modified at the same time. Please modify and debug according to the actual situation. It is suggested to run `module.py` directly for debugging after modification before starting the service test.
+- 3. Uninstall old service module
+```shell
+hub uninstall ocr_system
+```
+- 4. Install modified service module
+```shell
+hub install deploy/hubserving/ocr_system/
+```
+- 5. Restart service
+```shell
+hub serving start -m ocr_system
+```

+# 添加新算法
+
+PaddleOCR将一个算法分解为以下几个部分，并对各部分进行模块化处理，方便快速组合出新的算法。
+
+* 数据加载和处理
+* 网络
+* 后处理
+* 损失函数
+* 指标评估
+* 优化器
+
+下面将分别对每个部分进行介绍，并介绍如何在该部分里添加新算法所需模块。
+
+## 数据加载和处理
+
+数据加载和处理由不同的模块(module)组成，其完成了图片的读取、数据增强和label的制作。这一部分在[ppocr/data](../../ppocr/data)下。 各个文件及文件夹作用说明如下:
+
+```bash
+ppocr/data/
+├── imaug # 图片的读取、数据增强和label制作相关的文件
+│ ├── label_ops.py # 对label进行变换的modules
+│ ├── operators.py # 对image进行变换的modules
+│ ├──.....
+├── __init__.py
+├── lmdb_dataset.py # 读取lmdb的数据集的dataset
+└── simple_dataset.py # 读取以`image_path\tgt`形式保存的数据集的dataset
+```
+
+PaddleOCR内置了大量图像操作相关模块，对于没有没有内置的模块可通过如下步骤添加:
+
+1. 在 [ppocr/data/imaug](../../ppocr/data/imaug) 文件夹下新建文件，如my_module.py。
+2. 在 my_module.py 文件内添加相关代码，示例代码如下:
+
+```python
+class MyModule:
+ def __init__(self, *args, **kwargs):
+ # your init code
+ pass
+
+ def __call__(self, data):
+ img = data['image']
+ label = data['label']
+ # your process code
+
+ data['image'] = img
+ data['label'] = label
+ return data
+```
+
+3. 在 [ppocr/data/imaug/\__init\__.py](../../ppocr/data/imaug/__init__.py) 文件内导入添加的模块。
+
+数据处理的所有处理步骤由不同的模块顺序执行而成，在config文件中按照列表的形式组合并执行。如:
+
+```yaml
+# angle class data process
+transforms:
+ - DecodeImage: # load image
+ img_mode: BGR
+ channel_first: False
+ - MyModule:
+ args1: args1
+ args2: args2
+ - KeepKeys:
+ keep_keys: [ 'image', 'label' ] # dataloader will return list in this order
+```
+
+## 网络
+
+网络部分完成了网络的组网操作，PaddleOCR将网络划分为四部分，这一部分在[ppocr/modeling](../../ppocr/modeling)下。 进入网络的数据将按照顺序(transforms->backbones->
+necks->heads)依次通过这四个部分。
+
+```bash
+├── architectures # 网络的组网代码
+├── transforms # 网络的图像变换模块
+├── backbones # 网络的特征提取模块
+├── necks # 网络的特征增强模块
+└── heads # 网络的输出模块
+```
+
+PaddleOCR内置了DB,EAST,SAST,CRNN和Attention等算法相关的常用模块，对于没有内置的模块可通过如下步骤添加，四个部分添加步骤一致，以backbones为例:
+
+1. 在 [ppocr/modeling/backbones](../../ppocr/modeling/backbones) 文件夹下新建文件，如my_backbone.py。
+2. 在 my_backbone.py 文件内添加相关代码，示例代码如下:
+
+```python
+import paddle
+import paddle.nn as nn
+import paddle.nn.functional as F
+
+
+class MyBackbone(nn.Layer):
+ def __init__(self, *args, **kwargs):
+ super(MyBackbone, self).__init__()
+ # your init code
+ self.conv = nn.xxxx
+
+ def forward(self, inputs):
+ # your necwork forward
+ y = self.conv(inputs)
+ return y
+```
+
+3. 在 [ppocr/modeling/backbones/\__init\__.py](../../ppocr/modeling/backbones/__init__.py)文件内导入添加的模块。
+
+在完成网络的四部分模块添加之后，只需要配置文件中进行配置即可使用，如:
+
+```yaml
+Architecture:
+ model_type: rec
+ algorithm: CRNN
+ Transform:
+ name: MyTransform
+ args1: args1
+ args2: args2
+ Backbone:
+ name: MyBackbone
+ args1: args1
+ Neck:
+ name: MyNeck
+ args1: args1
+ Head:
+ name: MyHead
+ args1: args1
+```
+
+## 后处理
+
+后处理实现解码网络输出获得文本框或者识别到的文字。这一部分在[ppocr/postprocess](../../ppocr/postprocess)下。
+PaddleOCR内置了DB,EAST,SAST,CRNN和Attention等算法相关的后处理模块，对于没有内置的组件可通过如下步骤添加:
+
+1. 在 [ppocr/postprocess](../../ppocr/postprocess) 文件夹下新建文件，如 my_postprocess.py。
+2. 在 my_postprocess.py 文件内添加相关代码，示例代码如下:
+
+```python
+import paddle
+
+
+class MyPostProcess:
+ def __init__(self, *args, **kwargs):
+ # your init code
+ pass
+
+ def __call__(self, preds, label=None, *args, **kwargs):
+ if isinstance(preds, paddle.Tensor):
+ preds = preds.numpy()
+ # you preds decode code
+ preds = self.decode_preds(preds)
+ if label is None:
+ return preds
+ # you label decode code
+ label = self.decode_label(label)
+ return preds, label
+
+ def decode_preds(self, preds):
+ # you preds decode code
+ pass
+
+ def decode_label(self, preds):
+ # you label decode code
+ pass
+```
+
+3. 在 [ppocr/postprocess/\__init\__.py](../../ppocr/postprocess/__init__.py)文件内导入添加的模块。
+
+在后处理模块添加之后，只需要配置文件中进行配置即可使用，如:
+
+```yaml
+PostProcess:
+ name: MyPostProcess
+ args1: args1
+ args2: args2
+```
+
+## 损失函数
+
+损失函数用于计算网络输出和label之间的距离。这一部分在[ppocr/losses](../../ppocr/losses)下。
+PaddleOCR内置了DB,EAST,SAST,CRNN和Attention等算法相关的损失函数模块，对于没有内置的模块可通过如下步骤添加:
+
+1. 在 [ppocr/losses](../../ppocr/losses) 文件夹下新建文件，如 my_loss.py。
+2. 在 my_loss.py 文件内添加相关代码，示例代码如下:
+
+```python
+import paddle
+from paddle import nn
+
+
+class MyLoss(nn.Layer):
+ def __init__(self, **kwargs):
+ super(MyLoss, self).__init__()
+ # you init code
+ pass
+
+ def __call__(self, predicts, batch):
+ label = batch[1]
+ # your loss code
+ loss = self.loss(input=predicts, label=label)
+ return {'loss': loss}
+```
+
+3. 在 [ppocr/losses/\__init\__.py](../../ppocr/losses/__init__.py)文件内导入添加的模块。
+
+在损失函数添加之后，只需要配置文件中进行配置即可使用，如:
+
+```yaml
+Loss:
+ name: MyLoss
+ args1: args1
+ args2: args2
+```
+
+## 指标评估
+
+指标评估用于计算网络在当前batch上的性能。这一部分在[ppocr/metrics](../../ppocr/metrics)下。 PaddleOCR内置了检测，分类和识别等算法相关的指标评估模块，对于没有内置的模块可通过如下步骤添加:
+
+1. 在 [ppocr/metrics](../../ppocr/metrics) 文件夹下新建文件，如my_metric.py。
+2. 在 my_metric.py 文件内添加相关代码，示例代码如下:
+
+```python
+
+class MyMetric(object):
+ def __init__(self, main_indicator='acc', **kwargs):
+ # main_indicator is used for select best model
+ self.main_indicator = main_indicator
+ self.reset()
+
+ def __call__(self, preds, batch, *args, **kwargs):
+ # preds is out of postprocess
+ # batch is out of dataloader
+ labels = batch[1]
+ cur_correct_num = 0
+ cur_all_num = 0
+ # you metric code
+ self.correct_num += cur_correct_num
+ self.all_num += cur_all_num
+ return {'acc': cur_correct_num / cur_all_num, }
+
+ def get_metric(self):
+ """
+ return metircs {
+ 'acc': 0,
+ 'norm_edit_dis': 0,
+ }
+ """
+ acc = self.correct_num / self.all_num
+ self.reset()
+ return {'acc': acc}
+
+ def reset(self):
+ # reset metric
+ self.correct_num = 0
+ self.all_num = 0
+
+```
+
+3. 在 [ppocr/metrics/\__init\__.py](../../ppocr/metrics/__init__.py)文件内导入添加的模块。
+
+在指标评估模块添加之后，只需要配置文件中进行配置即可使用，如:
+
+```yaml
+Metric:
+ name: MyMetric
+ main_indicator: acc
+```
+
+## 优化器
+
+优化器用于训练网络。优化器内部还包含了网络正则化和学习率衰减模块。 这一部分在[ppocr/optimizer](../../ppocr/optimizer)下。 PaddleOCR内置了`Momentum`,`Adam`
+和`RMSProp`等常用的优化器模块，`Linear`,`Cosine`,`Step`和`Piecewise`等常用的正则化模块与`L1Decay`和`L2Decay`等常用的学习率衰减模块。
+对于没有内置的模块可通过如下步骤添加，以`optimizer`为例:
+
+1. 在 [ppocr/optimizer/optimizer.py](../../ppocr/optimizer/optimizer.py) 文件内创建自己的优化器，示例代码如下:
+
+```python
+from paddle import optimizer as optim
+
+
+class MyOptim(object):
+ def __init__(self, learning_rate=0.001, *args, **kwargs):
+ self.learning_rate = learning_rate
+
+ def __call__(self, parameters):
+ # It is recommended to wrap the built-in optimizer of paddle
+ opt = optim.XXX(
+ learning_rate=self.learning_rate,
+ parameters=parameters)
+ return opt
+
+```
+
+在优化器模块添加之后，只需要配置文件中进行配置即可使用，如:
+
+```yaml
+Optimizer:
+ name: MyOptim
+ args1: args1
+ args2: args2
+ lr:
+ name: Cosine
+ learning_rate: 0.001
+ regularizer:
+ name: 'L2'
+ factor: 0
+```

+# Add new algorithm
+
+PaddleOCR decomposes an algorithm into the following parts, and modularizes each part to make it more convenient to develop new algorithms.
+
+* Data loading and processing
+* Network
+* Post-processing
+* Loss
+* Metric
+* Optimizer
+
+The following will introduce each part separately, and introduce how to add the modules required for the new algorithm.
+
+
+## Data loading and processing
+
+Data loading and processing are composed of different modules, which complete the image reading, data augment and label production. This part is under [ppocr/data](../../ppocr/data). The explanation of each file and folder are as follows:
+
+```bash
+ppocr/data/
+├── imaug # Scripts for image reading, data augment and label production
+│ ├── label_ops.py # Modules that transform the label
+│ ├── operators.py # Modules that transform the image
+│ ├──.....
+├── __init__.py
+├── lmdb_dataset.py # The dataset that reads the lmdb
+└── simple_dataset.py # Read the dataset saved in the form of `image_path\tgt`
+```
+
+PaddleOCR has a large number of built-in image operation related modules. For modules that are not built-in, you can add them through the following steps:
+
+1. Create a new file under the [ppocr/data/imaug](../../ppocr/data/imaug) folder, such as my_module.py.
+2. Add code in the my_module.py file, the sample code is as follows:
+
+```python
+class MyModule:
+ def __init__(self, *args, **kwargs):
+ # your init code
+ pass
+
+ def __call__(self, data):
+ img = data['image']
+ label = data['label']
+ # your process code
+
+ data['image'] = img
+ data['label'] = label
+ return data
+```
+
+3. Import the added module in the [ppocr/data/imaug/\__init\__.py](../../ppocr/data/imaug/__init__.py) file.
+
+All different modules of data processing are executed by sequence, combined and executed in the form of a list in the config file. Such as:
+
+```yaml
+# angle class data process
+transforms:
+ - DecodeImage: # load image
+ img_mode: BGR
+ channel_first: False
+ - MyModule:
+ args1: args1
+ args2: args2
+ - KeepKeys:
+ keep_keys: [ 'image', 'label' ] # dataloader will return list in this order
+```
+
+## Network
+
+The network part completes the construction of the network, and PaddleOCR divides the network into four parts, which are under [ppocr/modeling](../../ppocr/modeling). The data entering the network will pass through these four parts in sequence(transforms->backbones->
+necks->heads).
+
+```bash
+├── architectures # Code for building network
+├── transforms # Image Transformation Module
+├── backbones # Feature extraction module
+├── necks # Feature enhancement module
+└── heads # Output module
+```
+
+PaddleOCR has built-in commonly used modules related to algorithms such as DB, EAST, SAST, CRNN and Attention. For modules that do not have built-in, you can add them through the following steps, the four parts are added in the same steps, take backbones as an example:
+
+1. Create a new file under the [ppocr/modeling/backbones](../../ppocr/modeling/backbones) folder, such as my_backbone.py.
+2. Add code in the my_backbone.py file, the sample code is as follows:
+
+```python
+import paddle
+import paddle.nn as nn
+import paddle.nn.functional as F
+
+
+class MyBackbone(nn.Layer):
+ def __init__(self, *args, **kwargs):
+ super(MyBackbone, self).__init__()
+ # your init code
+ self.conv = nn.xxxx
+
+ def forward(self, inputs):
+ # your necwork forward
+ y = self.conv(inputs)
+ return y
+```
+
+3. Import the added module in the [ppocr/modeling/backbones/\__init\__.py](../../ppocr/modeling/backbones/__init__.py) file.
+
+After adding the four-part modules of the network, you only need to configure them in the configuration file to use, such as:
+
+```yaml
+Architecture:
+ model_type: rec
+ algorithm: CRNN
+ Transform:
+ name: MyTransform
+ args1: args1
+ args2: args2
+ Backbone:
+ name: MyBackbone
+ args1: args1
+ Neck:
+ name: MyNeck
+ args1: args1
+ Head:
+ name: MyHead
+ args1: args1
+```
+
+## Post-processing
+
+Post-processing realizes decoding network output to obtain text box or recognized text. This part is under [ppocr/postprocess](../../ppocr/postprocess).
+PaddleOCR has built-in post-processing modules related to algorithms such as DB, EAST, SAST, CRNN and Attention. For components that are not built-in, they can be added through the following steps:
+
+1. Create a new file under the [ppocr/postprocess](../../ppocr/postprocess) folder, such as my_postprocess.py.
+2. Add code in the my_postprocess.py file, the sample code is as follows:
+
+```python
+import paddle
+
+
+class MyPostProcess:
+ def __init__(self, *args, **kwargs):
+ # your init code
+ pass
+
+ def __call__(self, preds, label=None, *args, **kwargs):
+ if isinstance(preds, paddle.Tensor):
+ preds = preds.numpy()
+ # you preds decode code
+ preds = self.decode_preds(preds)
+ if label is None:
+ return preds
+ # you label decode code
+ label = self.decode_label(label)
+ return preds, label
+
+ def decode_preds(self, preds):
+ # you preds decode code
+ pass
+
+ def decode_label(self, preds):
+ # you label decode code
+ pass
+```
+
+3. Import the added module in the [ppocr/postprocess/\__init\__.py](../../ppocr/postprocess/__init__.py) file.
+
+After the post-processing module is added, you only need to configure it in the configuration file to use, such as:
+
+```yaml
+PostProcess:
+ name: MyPostProcess
+ args1: args1
+ args2: args2
+```
+
+## Loss
+
+The loss function is used to calculate the distance between the network output and the label. This part is under [ppocr/losses](../../ppocr/losses).
+PaddleOCR has built-in loss function modules related to algorithms such as DB, EAST, SAST, CRNN and Attention. For modules that do not have built-in modules, you can add them through the following steps:
+
+1. Create a new file in the [ppocr/losses](../../ppocr/losses) folder, such as my_loss.py.
+2. Add code in the my_loss.py file, the sample code is as follows:
+
+```python
+import paddle
+from paddle import nn
+
+
+class MyLoss(nn.Layer):
+ def __init__(self, **kwargs):
+ super(MyLoss, self).__init__()
+ # you init code
+ pass
+
+ def __call__(self, predicts, batch):
+ label = batch[1]
+ # your loss code
+ loss = self.loss(input=predicts, label=label)
+ return {'loss': loss}
+```
+
+3. Import the added module in the [ppocr/losses/\__init\__.py](../../ppocr/losses/__init__.py) file.
+
+After the loss function module is added, you only need to configure it in the configuration file to use it, such as:
+
+```yaml
+Loss:
+ name: MyLoss
+ args1: args1
+ args2: args2
+```
+
+## Metric
+
+Metric is used to calculate the performance of the network on the current batch. This part is under [ppocr/metrics](../../ppocr/metrics). PaddleOCR has built-in evaluation modules related to algorithms such as detection, classification and recognition. For modules that do not have built-in modules, you can add them through the following steps:
+
+1. Create a new file under the [ppocr/metrics](../../ppocr/metrics) folder, such as my_metric.py.
+2. Add code in the my_metric.py file, the sample code is as follows:
+
+```python
+
+class MyMetric(object):
+ def __init__(self, main_indicator='acc', **kwargs):
+ # main_indicator is used for select best model
+ self.main_indicator = main_indicator
+ self.reset()
+
+ def __call__(self, preds, batch, *args, **kwargs):
+ # preds is out of postprocess
+ # batch is out of dataloader
+ labels = batch[1]
+ cur_correct_num = 0
+ cur_all_num = 0
+ # you metric code
+ self.correct_num += cur_correct_num
+ self.all_num += cur_all_num
+ return {'acc': cur_correct_num / cur_all_num, }
+
+ def get_metric(self):
+ """
+ return metircs {
+ 'acc': 0,
+ 'norm_edit_dis': 0,
+ }
+ """
+ acc = self.correct_num / self.all_num
+ self.reset()
+ return {'acc': acc}
+
+ def reset(self):
+ # reset metric
+ self.correct_num = 0
+ self.all_num = 0
+
+```
+
+3. Import the added module in the [ppocr/metrics/\__init\__.py](../../ppocr/metrics/__init__.py) file.
+
+After the metric module is added, you only need to configure it in the configuration file to use it, such as:
+
+```yaml
+Metric:
+ name: MyMetric
+ main_indicator: acc
+```
+
+## 优化器
+
+The optimizer is used to train the network. The optimizer also contains network regularization and learning rate decay modules. This part is under [ppocr/optimizer](../../ppocr/optimizer). PaddleOCR has built-in
+Commonly used optimizer modules such as `Momentum`, `Adam` and `RMSProp`, common regularization modules such as `Linear`, `Cosine`, `Step` and `Piecewise`, and common learning rate decay modules such as `L1Decay` and `L2Decay`.
+Modules without built-in can be added through the following steps, take `optimizer` as an example:
+
+1. Create your own optimizer in the [ppocr/optimizer/optimizer.py](../../ppocr/optimizer/optimizer.py) file, the sample code is as follows:
+
+```python
+from paddle import optimizer as optim
+
+
+class MyOptim(object):
+ def __init__(self, learning_rate=0.001, *args, **kwargs):
+ self.learning_rate = learning_rate
+
+ def __call__(self, parameters):
+ # It is recommended to wrap the built-in optimizer of paddle
+ opt = optim.XXX(
+ learning_rate=self.learning_rate,
+ parameters=parameters)
+ return opt
+
+```
+
+After the optimizer module is added, you only need to configure it in the configuration file to use, such as:
+
+```yaml
+Optimizer:
+ name: MyOptim
+ args1: args1
+ args2: args2
+ lr:
+ name: Cosine
+ learning_rate: 0.001
+ regularizer:
+ name: 'L2'
+ factor: 0
+```
