Training (Tesla V100, 16GB)

• Train CycleGAN using the official experimental settings, or download our pretrained models.

• Train F_t

python train.py --model ft --gpu_ids 0 --batchSize 8 --loadSize 256 1024 --g_tgt_premodel ./cyclegan/G_Tgt.pth

• Train F_s

python train.py --model fs --gpu_ids 0 --batchSize 8 --loadSize 256 1024 --g_src_premodel ./cyclegan/G_Src.pth

• Train GASDA using the pretrained F_s, F_t and CycleGAN.

python train.py --freeze_bn --freeze_in --model gasda --gpu_ids 0 --batchSize 3 --loadSize 192 640 --g_src_premodel ./cyclegan/G_Src.pth --g_tgt_premodel ./cyclegan/G_Tgt.pth --d_src_premodel ./cyclegan/D_Src.pth --d_tgt_premodel ./cyclegan/D_Tgt.pth --t_depth_premodel ./checkpoints/vkitti2kitti_ft_bn/**_net_G_Depth_T.pth --s_depth_premodel ./checkpoints/vkitti2kitti_fs_bn/**_net_G_Depth_S.pth 

Note: this training strategy is different from that in our paper.

Test

MODELS.

Copy the provided models to GASDA/checkpoints/vkitti2kitti_gasda/, and rename the models 1_* (e.g., 1_net_D_Src.pth), and then

python test.py --test_datafile 'test.txt' --which_epoch 1 --model gasda --gpu_ids 0 --batchSize 1 --loadSize 192 640
