Error while loading Lora

### Describe the bug

`Error(s) in loading state_dict for UNet2DConditionModel`. I have uploaded the model on hugging face. Error appears on load_lora_weights() function.

### Reproduction

```

from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0")
pipe.load_lora_weights("D1-3105/lora_bug-1")

prompt = "abstract portrait of 1girl,undefined gender,fragmented visual style,red and black color palette,evokes feelings of rebellion,passion,and freedom,blurred boundaries,high resolution,aesthetic,"
image = pipe(prompt).images[0]

```

### Logs

```shell

### Who can help?

Commencez par exécuter la reproduction fournie de DiffusionPipeline et examinez le point d’entrée load_lora_weights() avec les incompatibilités signalées dans le state-dict de UNet2DConditionModel. Comparez les formes des tenseurs du checkpoint avec les formes attendues par le modèle actuel ; l’issue est terminée lorsque le LoRA référencé se charge correctement et que le prompt s’exécute sans ces erreurs.

Rédigé par le modèle d'indexation à partir du texte de l'issue.
