💡 Note: You can compute the conditioning map using the NormalBaeDetector from the controlnet_aux library

python

from controlnet_aux import NormalBaeDetector
from diffusers.utils import load_image 

normal_bae = NormalBaeDetector.from_pretrained("lllyasviel/Annotators")

normal_bae.to("cuda")

# Load an image
im = load_image(
  "https://huggingface.co/jasperai/Flux.1-dev-Controlnet-Surface-Normals/resolve/main/examples/output.jpg"
)

surface = normal_bae(im)

Training

This model was trained with surface normals maps computed with Clipdrop's surface normals estimator model as well as an open-souce surface normals estimation model such as Boundary Aware Encoder (BAE).

Licence

This model falls under the Flux.1-dev model licence.
