⚙️ Setup Environments

For this project, we used python/3.8.5, cuda/11.0.3.

Repository

git clone https://github.com/yurujaja/DGInStyle-SegModel.git
cd DGInStyle-SegModel

Dependencies

export SegModel_PATH=/path/to/venv/segmodel # change this
python3 -m venv ${SegModel_PATH}
source ${SegModel_PATH}/bin/activate

# use --ignore-installed to override pytorch installation
pip install --ignore-installed -r requirements.txt -f https://download.pytorch.org/whl/torch_stable.html
# requires the other packages to be installed first
pip install mmcv-full==1.3.7  

📂 Setup Datasets

In domain generalization scenario, semantic segmentation models are trained exclusively with synthetic datasets and tested on target (real-world) datasets.

Synthetic Datasets:

• DGInStyle Datasets: Please put the DGInStyle produced dataset into data/dginstyle_gen.
• GTA: Please download all image and label packages from here and extract them to data/gta. Then run the following scripts to generate rare classes related files and sample GTA subsets based on rare class sampling.

  cd tools
  python convert_datasets/gta.py data/gta --nproc 8   # generate rare classes related files
  python rcs_sample_gta.py   # sample GTA subsets
  

Real-World Datasets:

Only evaluation datasets are essential for the real-world datasets.

• Cityscapes: Please download leftImg8bit_trainvaltest.zip and gt_trainvaltest.zip from here and extract them to data/cityscapes.

• BDD100K: Please download the 10K Images and Segmentation from here and extract it to data/bdd100k.

• Mapillary: Please download the mapillary-vistas-dataset_public_v1.2.zip from here and extract it to data/mapillary.

• ACDC: Please download rgb_anon_trainvaltest.zip and gt_trainval.zip from here and extract them to data/acdc. Further, please restructure the folders from condition/split/sequence/ to split/ using the following commands:

  rsync -a data/acdc/rgb_anon/*/val/*/* data/acdc/rgb_anon/val/
  rsync -a data/acdc/gt/*/val/*/*_labelTrainIds.png data/acdc/gt/val/

• Dark Zurich: Please download the Dark_Zurich_val_anon.zip from here and extract it to data/dark_zurich.

⚖️ Training

Use the following script to automatically generate and train the configs:

python run_experiments.py --exp <ID>

The training configs, logs and checkpoints are saved in work_dirs/. More information about the available experiments and their assigned IDs, can be found in experiments.py.

🪝 Testing & Predictions

To evaluate the model saved in work_dirs/your_exp/, run the following script:

sh test.sh work_dirs/your_exp/

To specify the dataset or visualizations, please refer to tools/test.py for further instructions.

Provided checkpoints

We provide the checkpoints, training logs and evaluation files for two DG models with MiT-B5 backbone: DAFormer and HRDA.
