博主自己也在github上提供了一个极好的行人重识别库，大家可以看看并下载和使用：

HJL-re-id

详细内容参见Readme部分

一、介绍

二、依赖项

一、介绍

Open-ReID是一个轻量级的行人重识别库，用于研究目的。

它旨在为不同的数据集提供统一的界面，一整套模型和评估指标，以及再现（接近）最新结果的示例。

二、依赖项

安装PyTorch（版本≥ 0.2.0）。

虽然Open-ReID同时支持python2和python3，但建议使用python3以获得更好的性能。

三、下载

1.下载地址为：https://cysu.github.io/open-reid/

2.我们下载它，并解压，如下：

四、安装

1.可以使用cmd运行：


  
   
    
     
    
    
     
      cd open-reid
     
    
   
    
     
    
    
     
      python setup.py install

2.使用IDE运行，可以debug得快一些，博主使用vs2019：

关于如何使用vs2019运行Python程序，详情请看博主博客：vs2019 开始自己的第一个Python程序——九九乘法表

（1）脚本参数就是install

（2）运行结果

（3）查看项目文件夹，可以看到多了3个文件夹：

bulid
dist
open_reid.egg-info

五、使用前的注意事项

1.期间会下载VIPeR数据集，该数据集包含632个行人图像对，每个图像已缩放为128x48像素大小。

Downloading http://users.soe.ucsc.edu/~manduchi/VIPeR.v1.0.zip to D:\vs2019_project\datasets\open-reid-master\examples\data\viper\raw\VIPeR.v1.0.zip

分为2个文件夹：

cam_a
cam_b

打开这2个文件夹，可以看到cam_a主要拍摄的是行人的正面照，cam_b主要拍摄是行人的侧身和背身照

（1）cam_a：

（2）cam_b：

2.此外，使用python3的用户需要更改reid文件夹底下的trainers.py文件的第33行，将

losses.update(loss.data[0], targets.size(0))

改为

losses.update(loss.data.item(), targets.size(0))

如下

六、快速开始（训练+测试）

参数解释：

-d：dataset，设置为viper
-b：batch size，设置为64
-j：workers，设置为2（可根据cpu内核线程数而定）
-a：arch，设置为resnet50（模型名称，可选'inception'， 'resnet18'， 'resnet34'， 'resnet50'， 'resnet101'，和 'resnet152'）

1.cmd运行examples文件夹底下的softmax_loss.py文件

python examples/softmax_loss.py -d viper -b 64 -j 2 -a resnet50 --logs-dir logs/softmax-loss/viper-resnet50

2.IDE运行，vs2019中设置softmax_loss.py文件为启动文件

3.运行程序：

训练，默认50个epoch

最后进行测试

4.此外，还会生成logs文件夹，如下：

5.我们的实验记录在logs\softmax-loss\viper-resnet50可以看到：

有每次训练的checkpoint
最好的checkpoint
实验记录log.txt（记录了控制台打印的实验信息）

是不是很好用呢~
