Atria is a monorepo of local packages managed with uv. The packages are not published to PyPI — installation is from source.

From source (recommended)

git clone https://github.com/atriaml/atria
cd atria
uv sync

uv sync reads the workspace pyproject.toml, resolves all local packages (atria_registry, atria_types, atria_datasets, etc.) from their subdirectories, and installs them as editable packages into the project's virtual environment.

Activating the environment

# activate the uv-managed venv
source .venv/bin/activate

# or run commands directly through uv
uv run python -c "import atria_registry"

Individual packages (from their subdirectory)

If you only need one module, you can install it in isolation from its own directory:

cd atria_registry
uv sync

Note that most modules depend on atria_registry and atria_types at minimum, so their own pyproject.toml will pull those in automatically.

Requirements

• Python 3.11
• uv (pip install uv or curl -Ls https://astral.sh/uv/install.sh | sh)
