Welcome to the fascinating world of Custom Diffusion 360! This innovative solution allows you to revolutionize the way you customize images by enabling precise control over the camera viewpoint in text-to-image diffusion models like Stable Diffusion. In this article, we will walk you through the steps needed to get started with this powerful tool, explain how it works, and provide troubleshooting tips to assist you along the way.

How It Works: The Analogy of a Photographer’s Lens

Imagine you’re a professional photographer eager to showcase your collection of stunning landscapes. Instead of relying solely on a static image taken from one angle, you have a special camera that can capture the same scene from different viewpoints—this is akin to what Custom Diffusion 360 achieves.

• Camera Viewpoint: Just like adjusting your camera to a desired angle or zoom level, Custom Diffusion 360 fine-tunes models based on a ~50 images multiview dataset to produce images from specific camera perspectives.
• FeatureNeRF Blocks: These are like specialized lenses in our analogy. They modify the output by conditioning the generation on specified camera poses, ensuring your images are tailored to reflect your vision.
• Stable Diffusion: Think of this as your camera body, the framework that holds everything together while allowing the attached lenses (FeatureNeRF blocks) to enhance image quality and specificity.

Getting Started with Custom Diffusion 360

Ready to dive in? Follow these steps to set up Custom Diffusion 360:

git clone https://github.com/customdiffusion360/custom-diffusion360.git
cd custom-diffusion360
conda create -n pose python=3.8
conda activate pose
pip install torch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 --index-url https://download.pytorch.org/whl/cu118
pip install -r requirements.txt

You will also need to install PyTorch3D. You can find the installation instructions here, or follow the steps below to install from the source:

conda install -c conda-forge cudatoolkit-dev -y
export CUDA_HOME=$CONDA_PREFIX
pip install git+https://github.com/facebookresearch/pytorch3d.git@stable

Downloading Models for Inference

Proceed to download the pretrained models by following these commands:

mkdir pretrained-models
cd pretrained-models
wget https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors
wget https://huggingface.co/stabilityai/sdxl-vae/resolve/main/sdxl_vae.safetensors

Inference with Provided Models

To explore your customized models, execute the following command:

python sample.py --custom_model_dir pretrained-models/car0 --output_dir outputs --prompt "a new car beside a field of blooming sunflowers."

Training with Custom Datasets

If you’re eager to train your models with your own data, you can use the provided datasets or create your own multi-view images. Make sure to use the following command:

python main.py --base configs/train_co3d_concept.yaml --name car0 --resume_from_checkpoint_custom pretrained-models/sd_xl_base_1.0.safetensors --no_date --set_from_main --data_category car --data_single_id 0

Troubleshooting

Like any tech journey, you may encounter bumps along the way. Here are some common issues and solutions:

• Installation Issues: Ensure your Conda and package versions are up to date. Consider reinstalling any failing packages.
• Data Download Problems: If you experience trouble with the wget commands, ensure you’re properly connected to the internet and try again.
• Model Loading Errors: Check the compatibility of your environment and ensure all dependencies are appropriately installed.
• Unexpected Output: If generated images aren’t meeting expectations, revisit the prompt or dataset quality. Sometimes, the difference in viewpoints can significantly alter results.
