|

Add the model used for inference. Use the Safetensors file as is. VAE, LoRA, and Textual Inversion are also configurable.
|
||||
|
||||
```
|
||||
```yml
|
||||
# ex)
|
||||
model:
|
||||
name: stable-diffusion-2-1
|
||||
repo_id: stabilityai/stable-diffusion-2-1
|
||||
name: stable-diffusion-1-5
|
||||
url: https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/v1-5-pruned.safetensors # Specify URL for the safetensor file.

|
||||
controlnets:
|
||||
- name: control_v11f1e_sd15_tile
|
||||
repo_id: lllyasviel/control_v11f1e_sd15_tile
|
||||
```
|
||||
|
||||
Use a model configured for Diffusers, such as the one found in [this repository](https://huggingface.co/stabilityai/stable-diffusion-2-1). Files in safetensor format shared by Civitai etc. need to be converted (you can do so with a script in the diffusers official repository).
|
||||
If you want to use LoRA and Textual Inversion, configure as follows.
|
||||
|
||||
[https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py](https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py)
|
||||
|
||||
```
|
||||
# Example of using conversion script
|
||||
python ./diffusers/scripts/convert_original_stable_diffusion_to_diffusers.py --from_safetensors \
|
||||
--checkpoint_path="Write the filename of safetensor format here" \
|
||||
--dump_path="Write the output path here" \
|
||||
--device='cuda:0'
|
||||
```
|
||||
|
||||
LoRA and Textual Inversion don't require any conversion and can directly use safetensors files. Add the download link to config.yml as below.
|
||||
|
||||
```
|
||||
```yml
|
||||
# Example
|
||||
loras:
|
||||
- name: lora_name.safetensors # Specify the LoRA file name. Any name is fine, but the extension `.safetensors` is required.
|
||||
download_url: download_link_here # Specify the download link for the safetensor file.

||||
