Generation quality of the nuimages-model

[zhangxiao696]

hello,
when I follow your codes train nuimages dataset, the clarity of image generation is very low

@zhangxiao696 Actually, I would say these demo images demonstrate quite good quality :), considering the default setting we provide is based on 256x256 resolution, which is significantly lower than the original 1600x900 real images.

I do recommend you increase the image resolution to 512x512 or even larger. What you need to do is simply modify the image resolution in the data config file and scale your learning rate linearly with you batch size. Consider adopting the gradient accumulation via the --gradient_accumulation_steps argument if necessary for your GPU resources.
