layered-config-tree 4.2.0

Renamed to vivarium-config-tree; this package is a redirect. See README.

NOTE: This repository has been archived.

The layered_config_tree package has been renamed and migrated into the vivarium-suite monorepo.

What changed

• PyPI distribution: layered_config_tree -> vivarium-config-tree

• Import path: layered_config_tree -> vivarium.config_tree

• Source: ihmeuw/layered_config_tree (archived) -> ihmeuw/vivarium-suite (under libs/config-tree/)

• Docs: https://vivarium-config-tree.readthedocs.io/

What this last release (v4.2.0) is

A backward-compatibility shim; installing it pulls in:

• vivarium-engine>=5.0.0 - the real implementation under the new import path.

• vivarium-compat>=0.6.0 - an import hook that lets import vivarium continue to work, emitting a DeprecationWarning. Update your imports before the hook is removed.

If you depend on a specific pre-rename version (e.g. vivarium==4.1.5), pin to that version - those earlier releases still ship the original module and continue to install standalone.

To migrate fully to the new package

Install:

pip install vivarium-engine  # was: pip install vivarium

Import:

import vivarium.engine  # was: import vivarium

Note

The class rename is a two-step migration when consumed through the import shim: from layered_config_tree import LayeredConfigTree still works because LayeredConfigTree is kept as a deprecated alias on the new module. To clear the deprecation warnings entirely, update both the import path and the class name to their new forms above.
