# Aligned Diffusion Model via DDPO |
|
|
|
Diffusion Model aligned with the following reward models and Denoising Diffusion Policy Optimization (DDPO) algorithm |
|
``` |
|
close-sourced vlm: claude3-opus gpt-4o gpt-4v |
|
``` |
|
|
|
## How to Use |
|
|
|
You can load the model and perform inference as follows: |
|
```python |
|
from diffusers import StableDiffusionPipeline, UNet2DConditionModel |
|
|
|
pretrained_model_name = "runwayml/stable-diffusion-v1-5" |
|
pipeline = StableDiffusionPipeline.from_pretrained(pretrained_model_name, torch_dtype=torch.float16) |
|
|
|
lora_path = os.path.join(""path/to/checkpoint"") |
|
pipeline.sd_pipeline.load_lora_weights(lora_path) |
|
pipeline.sd_pipeline.to("cuda") |
|
|
|
generator = torch.Generator(device='cuda') |
|
generator = generator.manual_seed(1) |
|
|
|
prompt = "a pink flower" |
|
|
|
image = pipeline(prompt=prompt, generator=generator, guidance_scale=5).images[0] |
|
``` |
