Installing mlxtend


To install mlxtend, just execute

pip install mlxtend  

Alternatively, you download the package manually from the Python Package Index, unzip it, navigate into the package, and use the command:

python install
Upgrading via pip

To upgrade an existing version of mlxtend from PyPI, execute

pip install mlxtend --upgrade --no-deps

Please note that the dependencies (NumPy and SciPy) will also be upgraded if you omit the --no-deps flag; use the --no-deps ("no dependencies") flag if you don't want this.

Installing mlxtend from the source distribution

In rare cases, users reported problems on certain systems with the default pip installation command, which installs mlxtend from the binary distribution ("wheels") on PyPI. If you should encounter similar problems, you could try to install mlxtend from the source distribution instead via

pip install --no-binary :all: mlxtend

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


The mlxtend package is also available through conda forge.

To install mlxtend using conda, use the following command:

conda install mlxtend --channel conda-forge

or simply

conda install mlxtend

if you added conda-forge to your channels (conda config --add channels conda-forge).

Dev Version

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

pip install git+git://

Or, you can fork the GitHub repository from and install mlxtend from your local drive via

python install
