Issue downloading Stable Diffusion 3.5 Medium

[mihok]

This model was released yesterday, so I imagine it may have something to do with that?

Running the following command:

python -m python_coreml_stable_diffusion.torch2coreml --convert-unet --chunk-unet --convert-text-encoder --convert-vae-encoder --convert-vae-decoder --convert-safety-checker --model-version stabilityai/stable-diffusion-3.5-medium -o models/

After downloading all of the necessary files, the following error happens:

Yeah I'm getting the same error, but calling diffusers directly (on amazon linux boxes):

import torch
from diffusers import StableDiffusion3Pipeline

pipe = StableDiffusion3Pipeline.from_pretrained("stabilityai/stable-diffusion-3.5-medium", torch_dtype=torch.bfloat16)
pipe = pipe.to("cuda")

ValueError: Cannot load /home/coder/.cache/huggingface/hub/models--stabilityai--stable-diffusion-3.5-medium/snapshots/b940f670f0eda2d07fbb75229e779da1ad11eb80/transformer because transformer_blocks.0.norm1.linear.bias expected shape tensor(..., device='meta', size=(9216,)), but got torch.Size([13824]).

Might not be an issue specifically with this repo

[fibrous-tendencies]

I was able to get the quantized version running after updating diffusers to the latest version.

Upgrade to the latest version of the 🧨 diffusers library pip install -U diffusers this solves my problem
