Updates

• Aug 16, 2019

  • The codes of training and testing for our ICCV19 paper are released.
  • We have cleared up and tested the codes on Market, Duke datasets, the expected retrieval performances are as follows:

  Market	R@1	R@5	R@10	mAP	Reference
  IDE+ERA	89.9%	96.4%	97.6%	75.6%	train_ide.py
  IDE+MHN6	93.1%	97.7%	98.7%	83.2%	train_ide.py
  PCB+ERA	91.7%	97.4%	98.3%	76.4%	train_smallPCB
  PCB+MHN4	94.3%	98.0%	98.8%	83.9%	train_smallPCB
  PCB+MHN6	94.8%	98.3%	98.9%	85.2%	train_smallPCB_multiGPU.py

  Duke	R@1	R@5	R@10	mAP	Reference
  IDE+ERA	82.7%	91.8%	94.1%	68.1%	train_ide.py
  IDE+MHN6	87.8%	94.2%	95.8%	74.6%	train_ide.py
  PCB+ERA	82.9%	91.7%	93.8%	67.7%	train_smallPCB
  PCB+MHN4	88.5%	94.5%	96.1%	76.9%	train_smallPCB
  PCB+MHN6	89.5%	94.7%	96.1%	77.5%	train_smallPCB_multiGPU.py

Files

• train_ide.py test_ide.py

  • files for training and testing on IDE framework

• train_smallPCB.py test_smallPCB.py

  • files for training and testing on PCB framework, when using MHN, the maximized order is limited to 4 due to the GPU memory.

• train_smallPCB_multiGPU.py test_smallPCB.py

  • files for training, if you want to test MHN6, please use this file for training with multi gpus. The testing file is also test_smallPCB.py

• auto_test.sh

  • auto-testing code.

Prerequisites

• Pytorch(0.4.0+)
• python3.6
• 2GPUs, each > 11G

Train_Model

1. Clone our code.
2. Download the training images {google drive, baidu}, including Market1501, DukeMTMC, CUHK03-NP.
3. Go into the MHN/ dir and mkdir datasets/, then unzip the downloaded datasets.zip to datasets/
4. Run prepare.py to preprocess the datasets.
5. Then you can try our methods

IDE+ERA

python3 train_ide.py --gpu_ids 0 --name ide --data_dir datasets/Market/datasets/pytorch/ --train_all --batchsize 32 --erasing_p 0.4 --balance_sampler

IDE+MHN6

python3 train_ide.py --gpu_ids 0 --name ide_mhn6 --data_dir datasets/Market/datasets/pytorch/ --train_all --batchsize 32 --erasing_p 0.4 --balance_sampler --alpha 1.4 --parts 6 --mhn

PCB+ERA

python3 train_smallPCB.py --gpu_ids 0 --name pcb --data_dir datasets/Market/datasets/pytorch/ --train_all --batchsize 32 --erasing_p 0.4 --balance_sampler

PCB+MHN4

python3 train_smallPCB.py --gpu_ids 0 --name pcb_mhn4 --data_dir datasets/Market/datasets/pytorch/ --train_all --batchsize 32 --erasing_p 0.4 --balance_sampler --alpha 2 --parts 4 --mhn

PCB+MHN6

python3 train_smallPCB_multiGPU.py --gpu_ids 0,1 --name pcb_mhn6 --data_dir datasets/Market/datasets/pytorch/ --train_all --batchsize 32 --erasing_p 0.4 --balance_sampler --alpha 2 --parts 6 --mhn

the trained models are stored in folder "model/($name)".

Evaluation

We provide the auto-testing code in auto_test.sh, you can replace the corresponding code for testing. For example,

For IDE+ERA

python3 test_ide.py --gpu_ids $gpu_ids --name ide --test_dir datasets/Market/datasets/pytorch/ --batchsize 32 --which_epoch $i

For IDE+MHN6

python3 test_ide.py --gpu_ids $gpu_ids --name ide_mhn6 --test_dir datasets/Market/datasets/pytorch/ --batchsize 20 --which_epoch $i --mhn --parts 6

For PCB+ERA

python3 test_smallPCB.py --gpu_ids $gpu_ids --name pcb --test_dir datasets/Market/datasets/pytorch/ --batchsize 32 --which_epoch $i

For PCB+MHN4

python3 test_smallPCB.py --gpu_ids $gpu_ids --name pcb_mhn4 --test_dir datasets/Market/datasets/pytorch/ --batchsize 15 --which_epoch $i --mhn --parts 4

For PCB+MHN6

python3 test_smallPCB.py --gpu_ids $gpu_ids --name pcb_mhn6 --test_dir datasets/Market/datasets/pytorch/ --batchsize 10 --which_epoch $i --mhn --parts 6
