# SVDQuant ComfyUI Node
**Note**: This node is **deprecated**! Please check **[ComfyUI-nunchaku/](https://github.com/mit-han-lab/ComfyUI-nunchaku/)** for the latest version.
![comfyui](../assets/comfyui.jpg)
## Installation
Please first install `nunchaku` following the instructions in [README.md](https://github.com/mit-han-lab/nunchaku?tab=readme-ov-file#installation). Then just install `image_gen_aux` with
```shell
pip install git+https://github.com/asomoza/image_gen_aux.git
```
### ComfyUI-CLI
```shell
pip install comfy-cli # install the comfyui-cli
comfy node registry-install svdquant
```
### ComfyUI-Manager (Experimental)
1. Install [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager) with the following commands then restart ComfyUI:
```shell
cd ComfyUI/custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Manager comfyui-manager
```
2. Open the Manager, search `svdquant` in the Custom Nodes Manager and then install it.
### Manual Installation
1. Install dependencies needed to run custom ComfyUI nodes:
```shell
pip install git+https://github.com/asomoza/image_gen_aux.git
```
2. Set up the dependencies for [ComfyUI](https://github.com/comfyanonymous/ComfyUI/tree/master) with the following commands:
```shell
git clone https://github.com/comfyanonymous/ComfyUI.git
cd ComfyUI
pip install -r requirements.txt
```
3. Navigate to the root directory of ComfyUI and link (or copy) the [`nunchaku/comfyui`](./) folder to `custom_nodes/svdquant`. For example:
```shell
# Clone repositories (skip if already cloned)
git clone https://github.com/comfyanonymous/ComfyUI.git
git clone https://github.com/mit-han-lab/nunchaku.git
cd ComfyUI
# Add SVDQuant nodes
cd custom_nodes
ln -s ../../nunchaku/comfyui svdquant
```
## Usage
1. **Set Up ComfyUI and SVDQuant**:
* SVDQuant workflows can be found at [`workflows`](./workflows). You can place them in `user/default/workflows` in ComfyUI root directory to load them. For example:
```shell
cd ComfyUI
# Copy workflow configurations
mkdir -p user/default/workflows
cp ../nunchaku/comfyui/workflows/* user/default/workflows/
```
* Install missing nodes (e.g., comfyui-inpainteasy) following [this tutorial](https://github.com/ltdrdata/ComfyUI-Manager?tab=readme-ov-file#support-of-missing-nodes-installation).
2. **Download Required Models**: Follow [this tutorial](https://comfyanonymous.github.io/ComfyUI_examples/flux/) and download the required models into the appropriate directories using the commands below:
```shell
huggingface-cli download comfyanonymous/flux_text_encoders clip_l.safetensors --local-dir models/text_encoders
huggingface-cli download comfyanonymous/flux_text_encoders t5xxl_fp16.safetensors --local-dir models/text_encoders
huggingface-cli download black-forest-labs/FLUX.1-schnell ae.safetensors --local-dir models/vae
```
3. **Run ComfyUI**: From ComfyUI’s root directory, execute the following command to start the application:
```shell
python main.py
```
4. **Select the SVDQuant Workflow**: Choose one of the SVDQuant workflows (workflows that start with `svdq-`) to get started. For the FLUX.1-Fill workflow, you can use the built-in MaskEditor tool to add mask on top of an image.
## SVDQuant Nodes
* **SVDQuant Flux DiT Loader**: A node for loading the FLUX diffusion model.
* `model_path`: Specifies the model location. If set to the folder starting with `mit-han-lab`, the model will be automatically downloaded from our Hugging Face repository. Alternatively, you can manually download the model directory by running the following command example:
```shell
huggingface-cli download mit-han-lab/svdq-int4-flux.1-dev --local-dir models/diffusion_models/svdq-int4-flux.1-dev
```
After downloading, specify the corresponding folder name as the `model_path`.
* `cpu_offload`: Enables CPU offloading for the transformer model. While this may reduce GPU memory usage, it can slow down inference. Memory usage will be further optimized in node v0.1.6.
* `device_id`: Indicates the GPU ID for running the model.
* **SVDQuant FLUX LoRA Loader**: A node for loading LoRA modules for SVDQuant FLUX models.
* Place your LoRA checkpoints in the `models/loras` directory. These will appear as selectable options under `lora_name`. Meanwhile, the [example Ghibsky LoRA](https://huggingface.co/aleksa-codes/flux-ghibsky-illustration) is included and will automatically download from our Hugging Face repository when used.
* `lora_format` specifies the LoRA format. Supported formats include:
* `auto`: Automatically detects the appropriate LoRA format.
* `diffusers` (e.g., [aleksa-codes/flux-ghibsky-illustration](https://huggingface.co/aleksa-codes/flux-ghibsky-illustration))
* `comfyui` (e.g., [Shakker-Labs/FLUX.1-dev-LoRA-Children-Simple-Sketch](https://huggingface.co/Shakker-Labs/FLUX.1-dev-LoRA-Children-Simple-Sketch))
* `xlab` (e.g., [XLabs-AI/flux-RealismLora](https://huggingface.co/XLabs-AI/flux-RealismLora))
* `svdquant` (e.g., [mit-han-lab/svdquant-lora-collection](https://huggingface.co/mit-han-lab/svdquant-lora-collection)).
* `base_model_name` specifies the path to the quantized base model. If `lora_format` is already set to `svdquant`, this option has no use. You can set it to the same value as `model_path` in the above **SVDQuant Flux DiT Loader**.
* **Note**: Currently, **only one LoRA** can be loaded at a time.
* **SVDQuant Text Encoder Loader**: A node for loading the text encoders.
* For FLUX, use the following files:
- `text_encoder1`: `t5xxl_fp16.safetensors`
- `text_encoder2`: `clip_l.safetensors`
* `t5_min_length`: Sets the minimum sequence length for T5 text embeddings. The default in `DualCLIPLoader` is hardcoded to 256, but for better image quality in SVDQuant, use 512 here.
* `t5_precision`: Specifies the precision of the T5 text encoder. Choose `INT4` to use the INT4 text encoder, which reduces GPU memory usage by approximately 15GB. Please install [`deepcompressor`](https://github.com/mit-han-lab/deepcompressor) when using it:
```shell
git clone https://github.com/mit-han-lab/deepcompressor
cd deepcompressor
pip install poetry
poetry install
```
* `int4_model`: Specifies the INT4 model location. This option is only used when `t5_precision` is set to `INT4`. By default, the path is `mit-han-lab/svdq-flux.1-t5`, and the model will automatically download from our Hugging Face repository. Alternatively, you can manually download the model directory by running the following command:
```shell
huggingface-cli download mit-han-lab/svdq-flux.1-t5 --local-dir models/text_encoders/svdq-flux.1-t5
```
After downloading, specify the corresponding folder name as the `int4_model`.
* **FLUX.1 Depth Preprocessor**: A node for loading the depth estimation model and output the depth map. `model_path` specifies the model location. If set to [`LiheYoung/depth-anything-large-hf`](https://huggingface.co/LiheYoung/depth-anything-large-hf), the model will be automatically downloaded from the Hugging Face repository. Alternatively, you can manually download the repository at `models/checkpoints` by running the following command example:
```shell
huggingface-cli download LiheYoung/depth-anything-large-hf --local-dir models/checkpoints/depth-anything-large-hf
```
