🪄ACE

ACE is a unified foundational model framework that supports a wide range of visual generation tasks. By defining CU for unifying multi-modal inputs across different tasks and incorporating long-context CU, we introduce historical contextual information into visual generation tasks, paving the way for ChatGPT-like dialog systems in visual generation.

ACE Models

Model	Status

ACE-0.6B-1024px
ACE-12B-FLUX-dev	Coming Soon

ACE Training

We offer a demonstration training YAML that enables the end-to-end training of ACE using a toy dataset. For a comprehensive overview of the hyperparameter configurations, please consult scepter/methods/edit/dit_ace_0.6b_512.yaml.

Prepare datasets

Please find the dataset class located in scepter/modules/data/dataset/ms_dataset.py, designed to facilitate end-to-end training using an open-source toy dataset. Download a dataset zip file from modelscope, and then extract its contents into the cache/datasets/ directory.

Should you wish to prepare your own datasets, we recommend consulting scepter/modules/data/dataset/ms_dataset.py for detailed guidance on the required data format.

Prepare initial weight

The ACE checkpoint has been uploaded to both ModelScope and HuggingFace platforms:

• ModelScope
• HuggingFace

In the provided training YAML configuration, we have designated the Modelscope URL as the default checkpoint URL. Should you wish to transition to Hugging Face, you can effortlessly achieve this by modifying the PRETRAINED_MODEL value within the YAML file (replace the prefix "ms://iic" to "hf://scepter-studio").

Start training

You can easily start training procedure by executing the following command:

# ACE-0.6B-512px
PYTHONPATH=. python scepter/tools/run_train.py --cfg scepter/methods/edit/dit_ace_0.6b_512.yaml
# ACE-0.6B-1024px
PYTHONPATH=. python scepter/tools/run_train.py --cfg scepter/methods/edit/dit_ace_0.6b_1024.yaml

ACE Chat Bot

We have developed a chatbot interface utilizing Gradio, designed to convert user input in natural language into visually captivating images that align semantically with the specified instructions. You can easily access this functionality by launching Scepter Studio with the following command:

PYTHONPATH=. python scepter/tools/webui.py --cfg scepter/methods/studio/scepter_ui.yaml --language zh --tab chatbot

Upon starting, you will find a "ChatBot" tab within the Gradio application, which serves as a chat-based interface to handle any requests related to image editing or generation.

🖥️ SCEPTER Studio

Launch

To fully experience SCEPTER Studio, you can launch the following command line:

pip install scepter
python -m scepter.tools.webui

or run after clone repo code

git clone https://github.com/modelscope/scepter.git
PYTHONPATH=. python scepter/tools/webui.py --cfg scepter/methods/studio/scepter_ui.yaml

The startup of SCEPTER Studio eliminates the need for manual downloading and organizing of models; it will automatically load the corresponding models and store them in a local directory. Depending on the network and hardware situation, the initial startup usually requires 15-60 minutes, primarily involving the download and processing of SDv1.5, SDv2.1, and SDXL models. Therefore, subsequent startups will become much faster (about one minute) as downloading is no longer required.

Modelscope Studio & Huggingface Space

We deploy a work studio on Modelscope that includes only the inference tab, please refer to ms_scepter_studio and hf_scepter_studio

⚙️️ ComfyUI Workflow

We support the use of all models in the ComfyUI Workflow through the following methods:

1. Automatic installation directly via the ComfyUI Manager by searching for the ComfyUI-Scepter node.
2. Manually install by moving custom_nodes from Scepter to ComfyUI.

git clone https://github.com/modelscope/scepter.git
cd path/to/scepter
pip install -e .
cp -r path/to/scepter/workflow/ path/to/ComfyUI/custom_nodes/ComfyUI-Scepter
cd path/to/ComfyUI
python main.py

Note: You can use the nodes by dragging the sample images into ComfyUI. Additionally, our nodes can automatically pull models from ModelScope or HuggingFace by selecting the model_source field, or you can place the already downloaded models in a local path.
