# Latent Consistency Model (LCM) LoRA: SSD-Tiny
|
| 12 |
+
|
| 13 |
+
Latent Consistency Model (LCM) LoRA was proposed in [LCM-LoRA: A universal Stable-Diffusion Acceleration Module](https://arxiv.org/abs/2311.05556)
|
| 14 |
+
by *Simian Luo, Yiqin Tan, Suraj Patil, Daniel Gu et al.*
|
| 15 |
+
|
| 16 |
+
It is a distilled consistency adapter for [`segmind/SSD-Tiny`]("https://huggingface.co/segmind/SSD-1B") that allows
|
| 17 |
+
to reduce the number of inference steps to only between **2 - 8 steps**.

## Usage
|
| 26 |
+
|
| 27 |
+
LCM-LoRA is supported in 🤗 Hugging Face Diffusers library from version v0.23.0 onwards. To run the model, first
|
| 28 |
+
install the latest version of the Diffusers library as well as `peft`, `accelerate` and `transformers`.
|
| 29 |
+
audio dataset from the Hugging Face Hub:
|
| 30 |
+
|
| 31 |
+
```bash
|
| 32 |
+
pip install --upgrade pip
|
| 33 |
+
pip install --upgrade diffusers transformers accelerate peft
|
| 34 |
+
```
|
| 35 |
+
|
| 36 |
+
### Text-to-Image
|
| 37 |
+
|
| 38 |
+
Let's load the base model `segmind/SSD-Tiny` first. Next, the scheduler needs to be changed to [`LCMScheduler`](https://huggingface.co/docs/diffusers/v0.22.3/en/api/schedulers/lcm#diffusers.LCMScheduler) and we can reduce the number of inference steps to just 2 to 8 steps.
|
| 39 |
+
Please make sure to either disable `guidance_scale` or use values between 1.0 and 2.0.
|
| 40 |
+
|
| 41 |
+
```python
|
| 42 |
+
import torch
|
| 43 |
+
from diffusers import LCMScheduler, AutoPipelineForText2Image
|
| 44 |
+
|
| 45 |
+
model_id = "segmind/SSD-Tiny"
|
| 46 |
+
adapter_id = "segmind/lcm-lora-ssd-tiny"
|
| 47 |
+
|
| 48 |
+
pipe = AutoPipelineForText2Image.from_pretrained(model_id, torch_dtype=torch.float16, variant="fp16")
|
| 49 |
+
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
|
| 50 |
+
pipe.to("cuda")
|
| 51 |
+
|
| 52 |
+
# load and fuse lcm lora
|
| 53 |
+
pipe.load_lora_weights(adapter_id)
|
| 54 |
+
pipe.fuse_lora()
|
| 55 |
+
|
| 56 |
+
|
| 57 |
+
prompt = "Self-portrait oil painting, a beautiful cyborg with golden hair, 8k"
|
| 58 |
+
|
| 59 |
+
# disable guidance_scale by passing 0
|
| 60 |
+
image = pipe(prompt=prompt, num_inference_steps=4, guidance_scale=0).images[0]
|
| 61 |
+
```
