Train

python main.py --phase train --dataset summer2winter --concat True

Test

python main.py --phase test --dataset summer2winter --concat True --num_attribute 3

Guide

python main.py --phase guide --dataset summer2winter --concat True --direction a2b --guide_img ./guide.jpg

Tips

• --concat
  • True : for the shape preserving translation (summer <-> winter) (default)
  • False : for the shape variation translation (cat <-> dog)
• --n_scale
  • Recommend n_scale = 3 (default)
  • Using the n_scale > 1, a.k.a. multiscale discriminator often gets better results
• --n_dis
  • If you use the multi-discriminator, then recommend n_dis = 4 (default)
  • If you don't the use multi-discriminator, then recommend n_dis = 6
• --n_d_con
  • Author use n_d_con = 3 (default)
  • Model can still generate diverse results with n_d_con = 1
• --num_attribute (only for the test phase)
  • If you use the num_attribute > 1, then output images are variously generated
