Work done when Can Qin was an intern at Salesforce AI Research.
We introduce UniControl, a new generative foundation model that consolidates a wide array of controllable condition-to-image (C2I) tasks within a singular framework, while still allowing for arbitrary language prompts. UniControl enables pixel-level-precise image generation, where visual conditions primarily influence the generated structures and language prompts guide the style and context. To equip UniControl with the capacity to handle diverse visual conditions, we augment pretrained text-to-image diffusion models and introduce a task-aware HyperNet to modulate the diffusion models, enabling the adaptation to different C2I tasks simultaneously. Experimental results show that UniControl often surpasses the performance of single-task-controlled methods of comparable model sizes. This control versatility positions UniControl as a significant advancement in the realm of controllable visual generation.

There are more than 20M image-prompt-condition triplets here with total size > 2TB. It includes all 12 tasks (Canny, HED, Sketch, Depth, Normal, Skeleton, Bbox, Seg, Outpainting, Inpainting, Deblurring, Colorization) which are fully released.
Setup the env first (need to wait a few minutes).
conda env create -f environment.yaml
conda activate unicontrol
The checkpoint of pre-trained UniControl model is saved at ./ckpts/unicontrol.ckpt.
cd ckpts
wget https://storage.googleapis.com/sfr-unicontrol-data-research/unicontrol.ckpt
You can also use the latest trained model (ckpt and safetensors)
wget https://storage.googleapis.com/sfr-unicontrol-data-research/unicontrol_v1.1.ckpt
wget https://storage.googleapis.com/sfr-unicontrol-data-research/unicontrol_v1.1.st
If you want to train from scratch, please follow the ControlNet to prepare the checkpoint initialization. ControlNet provides a simple script for you to achieve this easily. If your SD filename is ./ckpts/v1-5-pruned.ckpt and you want the script to save the processed model (SD+ControlNet) at location ./ckpts/control_sd15_ini.ckpt, you can just run:
python tool_add_control.py ./ckpts/v1-5-pruned.ckpt ./ckpts/control_sd15_ini.ckpt
Please download the training dataset (MultiGen-20M) to ./multigen20m. Please:
cd multigen20m
gsutil -m cp -r gs://sfr-unicontrol-data-research/dataset ./
Then unzip the all the files.
Training from Scratch:
python train_unicontrol.py --ckpt ./ckpts/control_sd15_ini.ckpt --config ./models/cldm_v15_unicontrol_v11.yaml --lr 1e-5
Model Finetuning:
python train_unicontrol.py --ckpt ./ckpts/unicontrol.ckpt --config ./models/cldm_v15_unicontrol.yaml --lr 1e-7
For different tasks, please run the code as follows. If you meet OOM error, please decrease the "--num_samples".
If you use safetensors model, you can load the model following ./load_model/load_safetensors_model.py

Gradio Demo (App Demo Video, CUDA 11.0 and Conda 4.12.0 work)
We have provided gradio demos for different tasks to use. The example images are saved at ./test_imgs.
For all the tasks (Canny, HED, Sketch, Depth, Normal, Human Pose, Seg, Bbox, Outpainting, Colorization, Deblurring, Inpainting) please run the following code:
python app/gradio_all_tasks.py
We support the direct condition-to-image generation (as shown above). Please unmark the Condition Extraction in UI if you want to upload condition image directly.

Negative prompts are very useful sometimes:
monochrome, lowres, bad anatomy, worst quality, low qualityare example negative prompts. -
UniControl can work well on some tasks (ie, Colorization and Deblurring) without ANY text prompts.
-
If OOM, let
--num_samples 1may be helpful
