Are you looking to enhance the performance of your diffusion models? Welcome to the world of OneDiff, an out-of-the-box acceleration library designed specifically for diffusion models. This guide is tailored to help you install and utilize OneDiff seamlessly, making your AI projects more efficient and powerful.

What is OneDiff?

OneDiff is a library that automatically accelerates popular diffusion models using just one line of code. It ensures compatibility with popular libraries like HF diffusers and ComfyUI. Additionally, it incorporates PyTorch code compilation tools and optimized GPU kernels, making it the ideal choice for AI enthusiasts.

Installation Steps

Follow these simple steps to get OneDiff up and running:

0. OS and GPU Compatibility

• Operating System: Supports Linux. For Windows users, it can be run under WSL (Windows Subsystem for Linux).
• GPU Requirements: Make sure you have NVIDIA GPUs for optimal performance.

1. Install PyTorch and Diffusers

Before you can use OneDiff, you’ll need to install the base libraries:

python3 -m pip install torch transformers==4.27.1 diffusers[torch]==0.19.3

2. Install a Compiler Backend

You have the option to install either Nexfort or OneFlow. Choose based on your model requirements:

• Nexfort: Recommended for DiT structural models or H100 devices.
• OneFlow: Recommended for all other cases, with ongoing optimizations transitioning to Nexfort.

Install Nexfort:

python3 -m pip install -U nexfort

Install OneFlow:

python3 -m pip install -U --pre oneflow -f https://github.com/siliconflow/oneflow_releases/releases/expanded_assets/community/cu118

3. Install OneDiff

Now that all prerequisites are in place, install OneDiff using either PyPI or from source:

• From PyPI:

python3 -m pip install --pre onediff

• From Source:

git clone https://github.com/siliconflow/onediff.git
cd onediff
python3 -m pip install -e .

Understanding OneDiff: An Analogy

Imagine you are a chef preparing gourmet meals. In the past, you had to use many intricate appliances and tools, all requiring your personal attention. This cooking process could take hours. Now, imagine a magical kitchen appliance that allows you to prepare entire meals by just pushing a single button. This is what OneDiff does for diffusion models. It simplifies complex acceleration processes into a streamlined tool, maximizing output while minimizing the time and effort required.

Troubleshooting

If you encounter any issues while installing or using OneDiff, consider the following troubleshooting steps:

• Ensure that your NVIDIA GPU drivers are up to date.
• Check compatibility with your OS and GPU specifications.
• If you face dependency issues, try installing the libraries in a new virtual environment.
