How many data was need to train a realistic generator?

Hi,

I'm trying to train a GAN by myself. Could you please tell me how many images are needed to get a realistic generator?

Also, I found that all of the links about VGGFace2 I can search from google are unavailable. Could you please where to find the VGGFace2 dataset?

I suggest you look into academic torrents if the dataset has been removed from the main page. The dataset contains around 3.3 million facial image. I randomly sample target/source pairs during training by shuffling the file_path order along with a shuffle buffer. I deemed FaceDancer finished training after 300k iterations (using batch size 10).
