@DN6 a friendly ping here.
@sayakpaul Just for my reference could you point me to some Pixart Single File checkpoints that are widely used?
Yeah when I added it I mistakenly thought a community uploaded checkpoint to be a single-file one. But it turned out to be diffusers and they didn't upload the config.json 🤷
Sorry for the trouble. I will close it but will keep the branch alive so that it can be revisited later if need be.
