Here is a script to apply a pix2pix model to facade label maps (stored in the directory `facades/testB`). ``` bash #!./scripts/test_single.sh python test.py --dataroot ./datasets/facades/testB/ --name facades_pix2pix --model test --which_model_netG unet_256 --which_direction BtoA --dataset_mode single ``` +Note: We currently don't have pretrained models using PyTorch. This is in part because the models trained using Torch and PyTorch produce slightly different results, although we were not able to decide which result is better. If you would like to generate the same results that appeared in our paper, we recommend using the pretrained models in the Torch codebase. + +### Apply a pre-trained model (pix2pix) + +Download the pre-trained models using `./pretrained_models/download_pix2pix_model.sh`.

You need a large batch size (e.g. `--batchSize 32`) to benefit from multiple GPUs. |
