Installing mlxtend

---

Using uv

To add mlxtend to a uv-managed project, run

uv add mlxtend

For a one-off command without changing your current project, run

uv run --with mlxtend python -c "import mlxtend; print(mlxtend.__version__)"

Upgrading via uv

To upgrade an existing uv project dependency, run

uv add -U mlxtend

This updates the dependency in your project and syncs the environment.

Installing mlxtend from the source distribution

In rare cases, users reported problems on certain systems with the default binary distribution from PyPI. If you encounter a similar problem, try installing mlxtend from the source distribution instead:

uv add --no-binary-package mlxtend mlxtend

Also, I would appreciate it if you could report any issues that occur when installing mlxtend so we can fix these in future releases.

Dev Version

The mlxtend version on PyPI may always be one step behind; you can install the latest development version from the GitHub repository by executing

uv add "mlxtend @ git+https://github.com/rasbt/mlxtend.git"

Or, you can fork the GitHub repository from https://github.com/rasbt/mlxtend and run mlxtend from your local checkout via

git clone https://github.com/<your_username>/mlxtend.git
cd mlxtend
uv sync --group dev
uv run python -c "import mlxtend; print(mlxtend.__version__)"
