Upgrade Scikit-Learn on Linux

scikit-learn can be easily installed on Linux using pip, the standard package installer for Python.

pip is included by default with Python 2 starting with version 2.7.9, and with Python 3 starting with version 3.4. This installation procedure will work on most Linux distributions, assuming Python and pip are already installed.

To install or upgrade scikit-learn, simply run the following command in your terminal:

pip install -U scikit-learn

To confirm that scikit-learn was successfully installed, you can import it in a Python script or interactive shell and print out the version number:

import sklearn
print(sklearn.__version__)

Running the example gives an output like:

1.5.0

• The first code block shows the pip command to install or upgrade scikit-learn to the latest version. The -U flag specifies to upgrade the package to the newest available version.

• The second code block imports the installed sklearn library and prints its version number using sklearn.__version__.

• This is a quick way to verify that scikit-learn was properly installed and is available for use in your Python environment.
