issues about CycleGAN

[IPNUISTlegal]

i can't find that how long is it spent on CycleGAN training to generate distorted images in your paper.
Does GTX 1080 have the ability to train CycleGAN?cause i found CycleGAN has nine residule_blocks!
I am not sure about what CycleGAN input is? distortion images and clear images？Where do these distortion images come from?
I just started learning GAN, thank you very much for replying！

Hi, how is your learning going?
I just read the paper. I think the authors wrote that they collected the images from ImageNet and visually classified the images into distorted images vs. non-distorted images.

@Xiaodong-Bran a little difficult，i am noob in python and deeplearning.
to my best knowledge， distorted images and non-distorted images were trainded by CycleGAN.
