作者以普遍使用的基于 ResNet50 的行人重识别模型为基础，探索并总结了以下几种有效且适用性较强的优化方法，大幅度提高了在多个行人重识别数据集上的指标。
1. Warmup：在训练一开始让学习率从一个较小值逐渐升高后再开始下降，有利于梯度下降优化时的稳定性，从而找到更优的参数模型。
2. Random erasing augmentation：随机区域擦除，通过数据增强来提升模型的泛化能力。

6. Center loss：给每个类别一个可学习的聚类中心，训练时让类内特征靠近聚类中心，减少类内差异，增大类间差异。
7. Reranking：在检索时考虑查询图像的近邻候选对象，根据候选对象的近邻图像的是否也含有查询图像的情况来优化距离矩阵，最终提升检索精度。
#### 2.1b 快速体验
快速体验章节主要以`softmax_triplet_with_center.yaml`配置和训练好的模型文件为例，在 Market1501 数据集上进行测试。
1. 下载[Market-1501-v15.09.15.zip](https://pan.baidu.com/s/1ntIi2Op?_at_=1654142245770)数据集，解压到`PaddleClas/dataset/`下，并组织成以下文件结构：

```
2. 下载 [reid_strong_baseline_softmax_with_center.epoch_120.pdparams](reid_strong_baseline_softmax_with_center.epoch_120.pdparams) 到 `PaddleClas/pretrained_models` 文件夹中
```shell

3. 使用下载好的 `softmax_triplet_with_center.pdparams` 在 Market1501 数据集上进行测试
```shell
python3.7 tools/eval.py \
-c ppcls/configs/reid/strong_baseline/softmax_triplet_with_center.yaml \

1. 下载[Market-1501-v15.09.15.zip](https://pan.baidu.com/s/1ntIi2Op?_at_=1654142245770)数据集，解压到`PaddleClas/dataset/`下，并组织成以下文件结构：

2. 执行以下命令开始训练
注：上述参考指标由使用作者开源的代码在我们的设备上训练多次得到，由于系统环境、torch版本、CUDA版本不同等原因，与作者提供的指标可能存在略微差异。
```shell
python3.7 tools/train.py -c ./ppcls/configs/reid/strong_baseline/softmax_triplet_with_center.yaml
```
接下来主要以`softmax_triplet_with_center.yaml`配置和训练好的模型文件为例，展示在 Market1501 数据集上进行训练、测试、推理的过程。
##### 2.1.2 数据准备
下载 [Market-1501-v15.09.15.zip](https://pan.baidu.com/s/1ntIi2Op?_at_=1654142245770) 数据集，解压到`PaddleClas/dataset/`下，并组织成以下文件结构：
```shell

├── bounding_box_test/

├── gt_query/
├── query/
├── generate_anno.py
├── bounding_box_test.txt
├── bounding_box_train.txt
├── query.txt
└── readme.txt
```
##### 2.1.3 模型训练
1. 执行以下命令开始训练
```shell
python3.7 tools/train.py -c ./ppcls/configs/reid/strong_baseline/softmax_triplet_with_center.yaml
```
注：单卡训练大约需要1个小时。
2. 查看训练日志和保存的模型参数文件
注：单卡训练大约需要1个小时。
训练过程中会在屏幕上实时打印loss等指标信息，同时会保存日志文件`train.log`、模型参数文件`*.pdparams`、优化器参数文件`*.pdopt`等内容到`Global.output_dir`指定的文件夹下，默认在`PaddleClas/output/RecModel/`文件夹下
- 模型测试
##### 2.1.4 模型评估
假设需要测试的模型文件路径为 `./output/RecModel/latest.pdparams` ，执行下述命令即可进行测试
准备用于评估的`*.pdparams`模型参数文件，可以使用训练好的模型，也可以使用[2.2 模型训练](#22-模型训练)中保存的模型。
- 以训练过程中保存的`latest.pdparams`为例，执行如下命令即可进行评估。
```shell
python3.7 tools/eval.py \
......@@ -138,57 +102,104 @@
-o Global.pretrained_model="./output/RecModel/latest"
```
注：`pretrained_model` 后填入的地址不需要加 `.pdparams` 后缀，在程序运行时会自动补上。
- 模型推理
- 以训练好的模型为例，下载 [reid_strong_baseline_softmax_with_center.epoch_120.pdparams](https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/reid/pretrain/reid_strong_baseline_softmax_with_center.epoch_120.pdparams) 到 `PaddleClas/pretrained_models` 文件夹中，执行如下命令即可进行评估。
1. 下载 inference 模型并解压：[reid_srong_baseline_softmax_with_center.tar](https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/reid/inference/reid_srong_baseline_softmax_with_center.tar)
```shell

tar xf reid_srong_baseline_softmax_with_center.tar
```
2. 修改 `PaddleClas/deploy/configs/inference_rec.yaml`。将 `infer_imgs:` 后的字段改为 Market1501 中 query 文件夹下的任意一张图片路径（下方代码使用的是`0294_c1s1_066631_00.jpg`图片路径）；将 `rec_inference_model_dir:` 后的字段改为解压出来的 reid_srong_baseline_softmax_with_center 文件夹路径；将 `transform_ops` 字段下的预处理配置改为 `softmax_triplet_with_center.yaml` 中`Eval.Query.dataset` 下的预处理配置。如下所示
```yaml
Global:

默认评估日志保存在`PaddleClas/output/RecModel/eval.log`中，可以看到我们提供的 `reid_strong_baseline_softmax_with_center.epoch_120.pdparams` 模型在 Market1501 数据集上的评估指标为recall@1=0.94270，recall@5=0.98189，mAP=0.85799
##### 2.1.5 模型推理
###### 2.1.5.1 模型导出
可以选择使用训练过程中保存的模型文件转换成 inference 模型并推理，或者使用我们提供的转换好的 inference 模型直接进行推理
- 将训练过程中保存的模型文件转换成 inference 模型，同样以`latest.pdparams`为例，执行以下命令进行转换
```shell
python3.7 tools/export_model.py \
-c ppcls/configs/reid/strong_baseline/softmax_triplet_with_center.yaml \
-o Global.pretrained_model="output/RecModel/latest" \
-o Global.save_inference_dir="./deploy/reid_srong_baseline_softmax_with_center"
```
- 或者下载并解压我们提供的 inference 模型
```shell
cd PaddleClas/deploy
wget https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/reid/inference/reid_srong_baseline_softmax_with_center.tar
tar xf reid_srong_baseline_softmax_with_center.tar
cd ../
```
###### 2.1.5.2 模型推理
