DreamBooth is a method to personalize text2image models like stable diffusion given just a few(3~5) images of a subject.
The training script in this repo is adapted from ShivamShrirao's diffuser repo. See here for detailed training command.
Docker file copy the ShivamShrirao's train_dreambooth.py to root directory. Replace any train_dreambooth.py in original doc with /train_dreambooth.py. Eg, if you want to run accelerate launch train_dreambooth.py you need to run following
sudo docker run -it --gpus=all --ipc=host -v $(pwd):/train -e HUGGING_FACE_HUB_TOKEN=$(cat ~/.huggingface/token) smy20011/dreambooth:latest \
accelerate launch /train_dreambooth.py (your arguments here)You need to install WSL with docker support. For linux users, make sure you have NVIDIA driver installed and have latest docker installed. If you still cannot access GPU, make sure you have nvidia container toolkit installed.
For Windows users, follow the guide here and here. You don't need to do the "CUDA Support for WSL2 section". You can also follow this Youtube video for reference as well.
Open the WSL terminal in Windows or open the terminal in Linux. Makesure you have huggingface-cli installed.
You need to accept the model license before downloading or using the weights. In this example we'll use model version v1-4, so you'll need to visit its card, read the license and tick the checkbox if you agree.
You have to be a registered user in 🤗 Hugging Face Hub, and you'll also need to use an access token for the code to work. For more information on access tokens, please refer to this section of the documentation.
Run the following command to authenticate your token
huggingface-cli loginNow let's get our dataset. Download images from here and save them in a directory. This will be our training data.
cd to the directory in your terminal. Run following command
export MODEL_NAME="CompVis/stable-diffusion-v1-4"
export INSTANCE_DIR="path-to-instance-images"
export OUTPUT_DIR="path-to-save-model"
sudo docker run -it --gpus=all --ipc=host -v $(pwd):/train -e HUGGING_FACE_HUB_TOKEN=$(cat ~/.huggingface/token) smy20011/dreambooth:latest \

According to the paper, it's recommended to generate num_epochs * num_samples images for prior-preservation. 200-300 works well for most cases.
