# kt-legacy — Legacy import names for Keras Tuner

License: permissive · Maintenance: abandoned · Downloads: 158.0K/mo

## What it is and what it does

kt-legacy is a compatibility shim for Keras Tuner that restores the old `kerastuner` import name. The main Keras Tuner repository changed its import name to `keras_tuner`, breaking code that relied on the older `kerastuner` name. This package exists solely to bridge that gap, allowing legacy code to continue importing under the old name without rewriting imports.

It has no runtime dependencies and installs as a pure Python wheel, making it lightweight. However, the package has been abandoned, with no maintenance since its latest release on 2023-04-12. It is a narrow-purpose tool—useful only if you have existing code that cannot be updated to use the new import name.

Use it for:

- Maintaining legacy code that imports Keras Tuner as `kerastuner` without refactoring imports
- Running older hyperparameter tuning scripts that depend on the deprecated import name
- Bridging a temporary gap during migration from old to new Keras Tuner import conventions

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides the deprecated `kerastuner` import name for Keras Tuner, allowing code written for older versions to continue working without modification.

Yes, but only if you have legacy code that cannot be updated to use `keras_tuner` and you need the old `kerastuner` import name to work. The package is abandoned and unmaintained, so it will not receive bug fixes or updates. For new projects, use the current Keras Tuner package with the `keras_tuner` import instead.

## Install

pip install kt-legacy
uv add kt-legacy
poetry add kt-legacy

## Installing kt-legacy

Before you install: No runtime dependencies and low install friction, but the package is abandoned—last release was 1220 days ago with no recent activity.

License in practice: Licensed under Apache License 2.0 (permissive), so you can use, modify, and distribute it freely with minimal restrictions.

Quickstart:

pip install kt-legacy

import kerastuner

Verify before relying:

- Whether this package actually re-exports Keras Tuner or merely provides an import shim
- What version(s) of Keras Tuner this package is compatible with
- Whether installing this alongside the current keras_tuner package causes conflicts
