Prepare ViT Pre-trained and HRNet Pre-trained Models

mkdir data

The ViT Pre-trained model can be found in ViT_Base, The HRNet Pre-trained model can be found in HRNet, please download it and put in the './weights' dictory.

Training

We use One GeForce GTX 1080Ti GPU for Training Before train the model, please modify the parameters in config file, please refer to Arguments in TransReID

python occ_train.py --config_file {config_file path}
#example
python occ_train.py --config_file 'configs/OCC_Duke/skeleton_pfd.yml'

Test the model

First download the Occluded-Duke model:Occluded-Duke

To test on pretrained model on Occ-Duke: Modify the pre-trained model path (PRETRAIN_PATH:ViT_Base, POSE_WEIGHT:HRNet, WEIGHT:Occluded-Duke) in yml, and then run:

## OccDuke for example
python test.py --config_file 'configs/OCC_Duke/skeleton_pfd.yml'

精度达不到论文里面的数据

作者您好，我在1501上测试了一下就改了 /home/zqx_3090/PersonReID/PersonReID2/PFD_Net-master/configs/Market1501/skeleton_pfd.yml 这个文件，里面的参数并没有改动改了权重的路径，和文件夹的路径其他都没变，如何训练300轮次后我选择最高300轮的 /home/zqx_3090/PersonReID/PersonReID2/PFD_Net-master/logs/Market/pfd_net/skeleton_transformer_300.pth 去测试结果是： 2021-12-28 18:23:39,417 PFDreid.test INFO: Validation Results 2021-12-28 18:23:39,417 PFDreid.test INFO: mAP: 88.2% 2021-12-28 18:23:39,418 PFDreid.test INFO: CMC curve, Rank-1 :94.8% 2021-12-28 18:23:39,418 PFDreid.test INFO: CMC curve, Rank-5 :98.3% 2021-12-28 18:23:39,418 PFDreid.test INFO: CMC curve, Rank-10 :99.0% 达不到论文的95.5 甚至不如TransReID的精度？？？您能看看是为什么嘛？

使用您的Occluded-Duke的预训练模型达不到文中的结果

作者您好：感谢你做出如此优秀的工作，我按照reademe的要求在使用您的Occluded-Duke的预训练模型时，发现达不到文中所说的结果，下图是我测试的结果：跟论文中的结果大约相差2%，我使用的时pytorch1.7.1, cuda10.2, python3.7.13;所以我想知道这是什么原因造成的呢？期待您的回复。

There is no Occlude-REID data loader

Good work! I respect your contributions!

I want to testing Occluded-REID dataset in your code, but there is no loader. In your code, dataset.make_dataloader.py, line 14 "from .occ_reid import Occluded_REID"

Would you share this code?

thank you
