Prerequisites

  • Python 3.6
  • GPU Memory >= 11G
  • Pytorch 1.0.0

Getting started

The data folder is structured as follows:

├── data/
│   ├── Cityscapes/     
|   |   ├── gtFine/
|   |   ├── leftImg8bit/
│   ├── GTA5/
|   |   ├── images/
|   |   ├── labels/
│   ├── SYNTHIA/ 
|   |   ├── RAND_CITYSCAPES/
│   └── 			
└── model/
│   ├── DeepLab_resnet_pretrained.pth
...

Train

CUDA_VISIBLE_DEVICES=0 python CLAN_train.py --snapshot-dir ./snapshots/GTA2Cityscapes

Evaluate

CUDA_VISIBLE_DEVICES=0 python CLAN_evaluate.py --restore-from  ./snapshots/GTA2Cityscapes/GTA5_100000.pth --save ./result/GTA2Cityscapes_100000

Our pretrained model is available via Google Drive

Compute IoU

python CLAN_iou.py ./data/Cityscapes/gtFine/val result/GTA2Cityscapes_100000

Tip: The best-performance model might not be the final one in the last epoch. If you want to evaluate every saved models in bulk, please use CLAN_evaluate_bulk.py and CLAN_iou_bulk.py, the result will be saved in an Excel sheet.

CUDA_VISIBLE_DEVICES=0 python CLAN_evaluate_bulk.py
python CLAN_iou_bulk.py
