Thanks for sharing this, absolutely amazing!
Tried running on:
MacBook Air M1 16GB
MacOS Ventura 13.0 (22A380)
Xcode 14.0.1 (14A400)
And got this error:
maple_diffusion/MapleDiffusion.swift:18: Fatal error: Unexpectedly found nil while unwrapping an Optional value

(lldb)
Seems like the files where generated on the bin folder:
Any idea what could be wrong?
Cheers from Stockholm!
Additional info...
The .ckpt file is a model created with StableDiffusion DreamBooth.
Would this be different than StableDiffusion?
Update...
Doing this hack, fixed my issue:
#18
Probably because it added the model files missed... But could this extra files somehow Messe my model inference?
I just pushed the missing file (alphas_cumprod.bin) directly to the repo, and I think Dreambooth models should load without crashing now. AFAIK all Stable Diffusion-derived models use the same alphas_cumprod, so it should be safe to include for everyone.
I tested converting moDi-v1-pruned.ckpt and it seems to load now.
