# 🛠️ Contributing to FastVideo
|
||
|
||
Thank you for your interest in contributing to FastVideo. We want the process
|
||
to be smooth and beginner‑friendly, whether you are adding a new pipeline,
|
||
improving performance, or fixing a bug.
|
||
|
||
## Quick prerequisites
|
||
|
||
- **OS**: Linux is the primary development target (WSL can work).
|
||
- **GPU**: NVIDIA GPU recommended for inference and training workflows.
|
||
- **CUDA**: Use a recent CUDA 12.x toolchain (see the installation guide for
|
||
the current recommendation).
|
||
|
||
For a full install checklist, see `docs/getting_started/installation/gpu.md`.
|
||
|
||
## Local development (Conda + editable install)
|
||
|
||
Install Miniconda:
|
||
|
||
```bash
|
||
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
|
||
bash Miniconda3-latest-Linux-x86_64.sh
|
||
source ~/.bashrc
|
||
```
|
||
|
||
Create and activate a Conda environment:
|
||
|
||
```bash
|
||
conda create -n fastvideo python=3.12 -y
|
||
conda activate fastvideo
|
||
```
|
||
|
||
Install `uv` (optional, but recommended):
|
||
|
||
```bash
|
||
curl -LsSf https://astral.sh/uv/install.sh | sh
|
||
# or
|
||
wget -qO- https://astral.sh/uv/install.sh | sh
|
||
```
|
||
|
||
Clone the repo:
|
||
|
||
```bash
|
||
git clone https://github.com/hao-ai-lab/FastVideo.git && cd FastVideo
|
||
```
|
||
|
||
Install FastVideo in editable mode and set up hooks:
|
||
|
||
```bash
|
||
uv pip install -e .[dev]
|
||
|
||
# Optional: FlashAttention (builds native kernels)
|
||
uv pip install flash-attn --no-build-isolation
|
||
|
||
# Linting, formatting, static typing
|
||
pre-commit install --hook-type pre-commit --hook-type commit-msg
|
||
pre-commit run --all-files
|
||
|
||
# Unit tests
|
||
pytest tests/
|
||
```
|
||
|
||
If you are on a Hopper GPU, installing FlashAttention 3 can improve
|
||
performance (see `docs/inference/optimizations.md`).
|
||
|
||
## Docker development (optional)
|
||
|
||
If you prefer a containerized environment, use the dev image documented in
|
||
`docs/contributing/developer_env/docker.md`.
|
||
|
||
## Testing
|
||
|
||
See the [Testing Guide](testing.md) for how to add and run tests in FastVideo.
|
||
|
||
## Attention backend development
|
||
|
||
If you are adding a new attention kernel or backend, follow
|
||
[Attention Backend Development](attention_backend.md).
|
||
|
||
## Contributing with coding agents
|
||
|
||
For a step‑by‑step workflow on adding pipelines or components with coding
|
||
agents, see `docs/contributing/coding_agents.md`.
