Wetlands
Wetlands lets a Python application run functions in separate Pixi environments.
This is useful when one application needs libraries whose dependencies cannot be installed together. Wetlands creates the environments, keeps worker processes ready for repeated calls, and transfers ordinary Python values between the application and workers.
Wetlands is intended for code you trust. Environments prevent dependency conflicts, but they do not restrict what code can access on your computer.
Install
pip install wetlands
Install the optional NumPy support when arrays cross the worker boundary:
pip install "wetlands[shared-memory]"
Run a task
from wetlands import EnvironmentManager, EnvironmentSpec
with EnvironmentManager(root="wetlands") as manager:
environment = manager.provision(
"first-example",
EnvironmentSpec(python="3.12.*"),
).wait_for()
with environment.start() as workers:
result = workers.execute_import(
"builtins:sum",
args=([20, 22],),
)
print(result) # 42
The first run may download Pixi and Python packages and can take several minutes.
Continue with the first-task tutorial or browse the complete documentation. Existing Wetlands 1 users should read the migration guide.
Development
Install the development environment:
uv sync --frozen --group dev --extra shared-memory
Run the fast tests and static checks:
uv run --extra shared-memory pytest -m "not integration and not compat and not manual"
uv run ruff check
uv run ruff format --check
uv run mypy src/wetlands
Start with the contributor setup and validation guide. The architecture guide explains the runtime design. Maintainers should follow RELEASING.md when publishing a release.
Wetlands is licensed under the MIT License. Read the security policy before executing third-party worker code or post-install commands.
