There are links on the readme there, or you can run:
> wandb artifact get --root=./pretrained/dalle_bart_mini dalle-mini/dalle-mini/mini-1:v0
and select option (3)
any way to download a pretrained dalle-mega model this way?
EDIT: wandb artifact get --root=./pretrained/dalle_bart_mega dalle-mini/dalle-mini/mega-1-fp16:v14
Note, it is a 4938MB download
