Developer-friendly port of the T2I-Adapter, Paper to diffusers. As a result, you are able to use all the pipelines at diffusers. You can also use my LoRA.
pip install git+https://github.com/cloneofsimo/t2i-adapter-diffusersExample code Using all of the adapters is at test_all.py. In short, you need to substitute UNet2DConditionModel to T2IAdapterUNet2DConditionModel. This can be done with patch_pipe.
Example with keypose adapter:
from t2i_adapters import patch_pipe, Adapter
# 1. Define model and patch to t2i-adapter
model_id = "runwayml/stable-diffusion-v1-5"
pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16).to(
device
)
patch_pipe(pipe)
# 2 Extract features with adapter
adapter = Adapter.from_pretrained("keypose").to(device)
# 2.1 prepare condition image
cond_img = Image.open(f"./contents/examples/{ext_type}_0.png").convert("RGB")
cond_img = np.array(cond_img)/255.0
cond_img = torch.from_numpy(cond_img).permute(2, 0, 1).unsqueeze(0).to(device).float()
# 2.2 prepare feature
with torch.no_grad():
adapter_features = adapter(cond_img)
# 3. set condition statefully. You can also call unet and make your own sampler. In that case, adapter feature attribute will be ignored.
pipe.unet.set_adapter_features(adapter_features)
# sample...
