 # FastDeploy集成新模型流程
 
-进行中...
+在FastDeploy里面新增一个模型，包括增加C++/Python的部署支持。 本文以torchvision v0.12.0中的ResNet50模型为例，介绍使用FastDeploy做外部[模型集成](#modelsupport)，具体包括如下3步。
+
+| 步骤 | 说明                                | 创建或修改的文件                            |
+|:------:|:-------------------------------------:|:---------------------------------------------:|
+| [1](#step2)    |  在fastdeploy/vision相应任务模块增加模型实现       | resnet.h、resnet.cc、vision.h                     |
+| [2](#step4)     | 通过pybind完成Python接口绑定 | resnet_pybind.cc、classification_pybind.cc |
+| [3](#step5)     | 实现Python相应调用接口    | resnet.py、\_\_init\_\_.py                        |
+
+在完成上述3步之后，一个外部模型就集成好了。
+<br />
+如果您想为FastDeploy贡献代码，还需要为新增模型添加测试代码、说明文档和代码注释，可在[测试](#test)中查看。
+## 模型集成     <span id="modelsupport"></span>
+
+### 模型准备  <span id="step1"></span>
+
+
+在集成外部模型之前，先要将训练好的模型（.pt，.pdparams 等）转换成FastDeploy支持部署的模型格式（.onnx，.pdmodel）。多数开源仓库会提供模型转换脚本，可以直接利用脚本做模型的转换。由于torchvision没有提供转换脚本，因此手动编写转换脚本，本文中将 `torchvison.models.resnet50` 转换为 `resnet50.onnx`， 参考代码如下：
+
+```python
+import torch
+import torchvision.models as models
+model = models.resnet50(pretrained=True)
+batch_size = 1  #批处理大小
+input_shape = (3, 224, 224)   #输入数据,改成自己的输入shape
+model.eval()
+x = torch.randn(batch_size, *input_shape)	# 生成张量
+export_onnx_file = "resnet50.onnx"			# 目的ONNX文件名
+torch.onnx.export(model,
+                    x,
+                    export_onnx_file,
+                    opset_version=12,
+                    input_names=["input"],	# 输入名
+                    output_names=["output"],	# 输出名
+                    dynamic_axes={"input":{0:"batch_size"},  # 批处理变量
+                                    "output":{0:"batch_size"}})
+```
+执行上述脚本将会得到 `resnet50.onnx` 文件。
+

+    * FastDeploy/fastdeploy/vision/classification/contrib/resnet.h (FastDeploy/C++代码存放位置/视觉模型/任务名称/外部模型/模型名.h)
+  * 创建内容
+    * 首先在resnet.h中创建 ResNet类并继承FastDeployModel父类，之后声明`Predict`、`Initialize`、`Preprocess`、`Postprocess`和`构造函数`，以及必要的变量，具体的代码细节请参考[resnet.h](https://github.com/PaddlePaddle/FastDeploy/pull/347/files#diff-69128489e918f305c208476ba793d8167e77de2aa7cadf5dcbac30da448bd28e)。

+  * 创建内容
+    * 在`resnet.cc`中实现`resnet.h`中声明函数的具体逻辑，其中`PreProcess` 和 `PostProcess`需要参考源官方库的前后处理逻辑复现，ResNet每个函数具体逻辑如下，具体的代码请参考[resnet.cc](https://github.com/PaddlePaddle/FastDeploy/pull/347/files#diff-d229d702de28345253a53f2a5839fd2c638f3d32fffa6a7d04d23db9da13a871)。
+
+```C++
+ResNet::ResNet(...) {
+  // 构造函数逻辑
+  // 1. 指定 Backend 2. 设置RuntimeOption 3. 调用Initialize()函数
+}
+bool ResNet::Initialize() {
+  // 初始化逻辑

+  return true;
+}
+bool ResNet::Preprocess(Mat* mat, FDTensor* output) {
+// 前处理逻辑
+// 1. Resize 2. BGR2RGB 3. Normalize 4. HWC2CHW 5. 处理结果存入 FDTensor类中  
+  return true;
+}
+bool ResNet::Postprocess(FDTensor& infer_result, ClassifyResult* result, int topk) {
+  //后处理逻辑
+  // 1. Softmax 2. Choose topk labels 3. 结果存入 ClassifyResult类
+  return true;
+}
+bool ResNet::Predict(cv::Mat* im, ClassifyResult* result, int topk) {
+  Preprocess(...)

+  Postprocess(...)

+### 为代码添加注释
+为了方便用户理解代码，我们需要为新增代码添加注释，添加注释方法可参考如下示例。
+- C++ 代码
+您需要在resnet.h文件中为函数和变量增加注释，有如下三种注释方式，具体可参考[resnet.h](https://github.com/PaddlePaddle/FastDeploy/pull/347/files#diff-69128489e918f305c208476ba793d8167e77de2aa7cadf5dcbac30da448bd28e)。
+
+```C++
+/** \brief Predict for the input "im", the result will be saved in "result".
+*
+* \param[in] im Input image for inference.
+* \param[in] result Saving the inference result.
+* \param[in] topk The length of return values, e.g., if topk==2, the result will include the 2 most possible class label for input image.
+*/
+virtual bool Predict(cv::Mat* im, ClassifyResult* result, int topk = 1);
+/// Tuple of (width, height)
+std::vector<int> size;
+/*! @brief Initialize for ResNet model, assign values to the global variables and call InitRuntime()
+*/
+bool Initialize();
+```
+- Python 代码
+你需要为resnet.py文件中的函数和变量增加适当的注释，示例如下，具体可参考[resnet.py](https://github.com/PaddlePaddle/FastDeploy/pull/347/files#diff-a4dc5ec2d450e91f1c03819bf314c238b37ac678df56d7dea3aab7feac10a157)。
+
+```python  
+  def predict(self, input_image, topk=1):
+    """Classify an input image
+    :param input_image: (numpy.ndarray)The input image data, 3-D array with layout HWC, BGR format
+    :param topk: (int)The topk result by the classify confidence score, default 1
+    :return: ClassifyResult
+    """
+    return self._model.predict(input_image, topk)
+```
+
+对于集成模型过程中的其他文件，您也可以对实现的细节添加适当的注释说明。
