Training & Testing

Train the source-only model

• Train with a pretrained ResNet model:

python so_run.py

where all the configs are in the ./config/so_config.yml file.

Train the value net model

• Train with selected source checkpoint:

python rl_run.py

where all the configs are in the ./config/rl_config.yml file.

Target adaptation

• Train with seg model + value net checkpoint:

python adaptive_target_run.py

where all the configs are in the ./config/adaptive_target_config.yml file.

To use multiple GPU:

Modify your GPU id in xx_run.py file. (replace xx with the corresponding training process)

e.g., os.environ["CUDA_VISIBLE_DEVICES"] = '0,1,2'

some important config in xx_config.yml:

• init_weight: initial weight from ResNet101 pretrained model
• restore_from: restore from a specific epoch address, e.g., epoch1.pth
• snapshot: the address you want to save your checkpoint.
• rl_restore_from: restore the seg model + value net checkpoint.
• plabel: your pseudo label path.

Note: run this experiment requires Weights & Biases to log the performance. Please install it in your own environment: pip install wandb
