How to modify the configuration file when using styleganv2 to generate a single-channel 800x800 SAR image?

[19990101lrk]

I want to use the styleganv2 model to generate SAR images as a data enhancement method for other tasks. I have a single-channel 800x800 SAR image. How to modify the configuration file to generate the same single-channel SAR image. I am currently modifying the configuration file. The image size can only be 512x512 or 1024x1024 and the image is three-channel RGB.
