About Intel® Extension For Scikit-Learn*

Designed for data scientists, Intel® Extension for Scikit-Learn* is a seamless way to speed up your Scikit-learn applications for machine learning to solve real-world problems. This extension package dynamically patches scikit-learn estimators to use Intel® oneAPI Data Analytics Library (oneDAL) as the underlying solver, while achieving the speed up for your machine learning algorithms.
Previously, these scikit-learn patch optimizations were available through daal4py, the Python API for Intel® oneAPI Data Analytics Library. All future updates for these patches for scikit-learn* will be available only in Intel® Extension for Scikit-learn. We recommend you to use Intel® Extension for Scikit-Learn* instead of daal4py.

Before You Begin

Please note that if you already have one of the latest versions of the scikit-learn* package installed, you do not need to remove or re-install it. Once enabled, Intel® Extension for Scikit-Learn* will seamlessly accelerate your existing scikit-learn* package.

If you do not already have scikit-learn* installed with your setup, upon installation Intel® Extension for Scikit-Learn will install a compatible version of scikit-learn* that can be used along with it.
For more information on which versions of scikit-learn* support Intel® Extension for Scikit-Learn, please review the Intel® Extension for Scikit-Learn* patching documentation.

Supported Installation Options

Install via Intel® oneAPI AI Analytics Toolkit

Intel® oneAPI AI Analytics Toolkit includes Scikit-Learn* alongside Intel® Extension for Scikit-Learn*. There are multiple ways to get the toolkit and its components. It is distributed through several channels – Anaconda, Docker containers, Package managers (Yum, Apt, Zypper) and an online / offline installer from Intel. To download Intel® Extension for Scikit-Learn* from the Intel® oneAPI AI Analytics Toolkit, visit here and choose the installation method of your choice. You can find more detailed information about the toolkit here.

Install via Individual Component

There are multiple options to only install Intel® Extension for Scikit-Learn*.
Linux*, Windows*, and MacOS* are supported (x86 architecture only). Refer to system requirements and supported configurations for details.

Install from Anaconda:

• Conda-Forge channel (recommended for users by defaut):
сonda install scikit-learn-intelex -c conda-forge
• Intel channel (recommended for Intel® Distribution for Python users):
conda install scikit-learn-intelex -c intel
• Defaults channel (recommended for users that prefer the main channel):
conda install scikit-learn-intelex

Install from PyPI:

pip install scikit-learn-intelex

Install from Container:

Note that a DockerHub account is required to properly access the links.

In order to install the latest Intel® Extension for Scikit-Learn as a Docker container, please use the following command:

docker pull intel/intel-optimized-ml:scikit-learn

Visit the Intel Optimized ML DockerHub* scikit-learn* container search list to see other available Intel containers that include Intel® Extension for Scikit-Learn and commands on how to pull them.

More containers, can be found on the Intel Optimized ML page on DockerHub*.

Build From Source

To build Intel® Extension for Scikit-Learn* from source, see the "Build From Source" instructions from the Intel® Extension for Scikit-Learn* documentation.

Getting Started with Intel® Extension for Scikit-Learn*: Usage and Sanity Check

There are a few ways to enable the Intel® Extension for Scikit-Learn* Optimizations:

• Command line:
python -m sklearnex my_application.py
• Or from your Python* script by patching Scikit-Learn* dynamically:
from sklearnex import patch_sklearn
patch_sklearn()

• To patch individual Scikit-Learn* algorithms, just import the specific Scikit-Learn* estimator you would like to optimized and use it
# from sklearn.svm import SVC
from sklearnex.svm import SVC

# normal code without any more changes

These methods can also be used as a sanity check that Intel® Extension for Scikit-Learn* is properly installed, as a warning should generate after usage telling the user that Intel® Extension for Scikit-Learn* accelerations have been enabled.

Support

If you have further questions or need support on your workload optimization, please submit your queries to the Intel® AI Analytics Toolkit Forum or Intel Extension for Scikit-Learn* GitHub, on the Issues or Discussions pages depending on the type of support required.
