[D] Where can I find pre-trained GANs for TensorFlow? • r/MachineLearning

I'm finding it very hard to find online any GAN model source code which comes with pre-trained parameters. Specifically, I'm interested in image generation (from random noise input), trained on a "challenging" data set such as ImageNet (even if downsampled...) (I'm less interested in MNIST...) Also, I'm wondering why is this so? So many papers appear with amazing results, and some of them share their code. Why don't they share their pre-trained models also? It would be very helpful for the community.
