ade2732c82 Transfer learning for styleSR 
This is a concept from "Lifelong Learning GAN", although I'm skeptical of it's novelty -
basically you scale and shift the weights for the generator and discriminator of a pretrained
GAN to "shift" into new modalities, e.g. faces->birds or whatever. There are some interesting
applications of this that I would like to try out.

8f18b2709e Get rid of CUDA_VISIBLE_DEVICES 
It is not clear to me what the purpose of this is, but it has recently
started causing failures.

1de1fa30ac Disable refs and centers altogether in single_image_dataset 
I suspect that this might be a cause of failures on parallel datasets.
Plus it is unnecessary computation.

e7aeb17404 ImageFolder dataset: allow intermediary downscale before corrupt 
For massive upscales (ex: 8x), corruption does almost nothing when applied
at the HQ level. This patch adds support to perform corruption at a specified
intermediary scale. The dataset downscales to this level, performs the corruption,
then downscales the rest of the way to get the LQ image.

4328c2f713 Change default ReLU slope to .2 BREAKS COMPATIBILITY 
This conforms my ConvGnLelu implementation with the generally accepted negative_slope=.2. I have no idea where I got .1. This will break backwards compatibility with some older models but will likely improve their performance when freshly trained. I did some auditing to find what these models might be, and I am not actively using any of them, so probably OK.

44a19cd37c ExtensibleTrainer mods to support advanced checkpointing for stylegan2 
Basically: stylegan2 makes use of gradient-based normalizers. These
make it so that I cannot use gradient checkpointing. But I love gradient
checkpointing. It makes things really, really fast and memory conscious.

So - only don't checkpoint when we run the regularizer loss. This is a
bit messy, but speeds up training by at least 20%.

Also: pytorch: please make checkpointing a first class citizen.
