I have tried to match official implementation as close as possible,
but maybe there are some details I missed. So please use this
implementation with care.
This will convert images to jpeg and pre-resizes it. This
implementation does not use progressive growing, but you can create
multiple resolution datasets using size arguments with comma separated
lists, for the cases that you want to try another resolutions later.
To match FID scores more closely to tensorflow official implementations, I have used FID Inception V3 implementations in https://github.com/mseitzer/pytorch-fid
