Official implementation of T2I-Adapter: Learning Adapters to Dig out More Controllable Ability for Text-to-Image Diffusion Models.

Paper

We propose T2I-Adapter, a simple and small (~70M parameters, ~300M storage space) network that can provide extra guidance to pre-trained text-to-image models while freezing the original large text-to-image models.

T2I-Adapter aligns internal knowledge in T2I models with external control signals. We can train various adapters according to different conditions, and achieve rich control and editing effects.

⏬ Download Models

Put the downloaded models in the T2I-Adapter/models folder.

The T2I-Adapters can be download from https://huggingface.co/TencentARC/T2I-Adapter.
The pretrained Stable Diffusion v1.4 models can be download from https://huggingface.co/CompVis/stable-diffusion-v-1-4-original/tree/main. You need to download the sd-v1-4.ckpt file.
[Optional] If you want to use Anything v4.0 models, you can download the pretrained models from https://huggingface.co/andite/anything-v4.0/tree/main. You need to download the anything-v4.0-pruned.ckpt file.
The pretrained clip-vit-large-patch14 folder can be download from https://huggingface.co/openai/clip-vit-large-patch14/tree/main. Remember to download the whole folder!

After downloading, the folder structure should be like this:

🔧 Dependencies and Installation

Python >= 3.6 (Recommend to use Anaconda or Miniconda)
PyTorch >= 1.4

pip install -r requirements.txt

💻 How to Test

The results are in the experiments folder.
If you want to use the Anything v4.0, please add --ckpt models/anything-v4.0-pruned.ckpt in the following commands.

Sketch Adapter

Sketch to Image Transition

python test_sketch.py --plms --auto_resume --prompt "A car with flying wings" --path_cond examples/sketch/car.png --ckpt models/sd-v1-4.ckpt --type_in sketch

Image to Image Transition

python test_sketch.py --plms --auto_resume --prompt "A beautiful girl" --path_cond examples/anything_sketch/human.png --ckpt models/sd-v1-4.ckpt --type_in image

Transition with Anything setting

python test_sketch.py --plms --auto_resume --prompt "A beautiful girl" --path_cond examples/anything_sketch/human.png --ckpt models/anything-v4.0-pruned.ckpt --type_in image

Gradio Demo

You can use gradio to experience all these three functions at once. CPU is also supported by setting device to 'cpu'.

python gradio_sketch.py

Keypose Adapter

python test_keypose.py --plms --auto_resume --prompt "An Iron man" --path_cond examples/keypose/iron.png

Segmentation Adapter

python test_seg.py --plms --auto_resume --prompt "A black Honda motorcycle parked in front of a garage" --path_cond examples/seg/motor.png

Two adapters: Segmentation and Sketch Adapters

python test_seg_sketch.py --plms --auto_resume --prompt "An all white kitchen with an electric stovetop" --path_cond examples/seg_sketch/mask.png --path_cond2 examples/seg_sketch/edge.png

Local editing with adapters

python test_sketch_edit.py --plms --auto_resume --prompt "A white cat" --path_cond examples/edit_cat/edge_2.png --path_x0 examples/edit_cat/im.png --path_mask examples/edit_cat/mask.png

Stable Diffusion + T2I-Adapters (only ~70M parameters, ~300M storage space)

The following is the detailed structure of a Stable Diffusion model with the T2I-Adapter.

🚀 Interesting Applications

Stable Diffusion results guided with the sketch T2I-Adapter

The corresponding edge maps are predicted by PiDiNet. The sketch T2I-Adapter can well generalize to other similar sketch types, for example, sketches from the Internet and user scribbles.

Stable Diffusion results guided with the keypose T2I-Adapter

The keypose results predicted by the MMPose. With the keypose guidance, the keypose T2I-Adapter can also help to generate animals with the same keypose, for example, pandas and tigers.

T2I-Adapter with Anything-v4.0

Once the T2I-Adapter is trained, it can act as a plug-and-play module and can be seamlessly integrated into the finetuned diffusion models without re-training, for example, Anything-4.0.
