Weakly Supervised Text-based Person Re-Identification

Note: We have open-sourced the trained model and the code necessary to the inference part, based on which you can easily reproduce the performance reported in the paper under a weakly supervised setting.

Retrieval Results on the CUHK-PEDES dataset

Requirement

• Python 3.5
• Pytorch 1.0.0 & torchvision 0.2.1
• numpy
• scipy 1.2.1

Data Preparation

• For downloading the CUHK-PEDES dataset, please follow link.
• Following CMPL, download the pre-computed/pre-extracted data from GoogleDrive.

Testing

1. Download the trained model from Google Drive.

2. Conduct the blow command:

sh scripts/run_test_res.sh

The result should be around:

top-1 = 57.10%
top-5 = 78.14%
top-10 = 85.23%
