Upgrade the Machine Learning Toolkit

The Machine Learning Toolkit (MLTK) regularly releases new features and enhancements. To learn about features and enhancements by released version, see What's new.

Requirements

Running version 5.0.0 or higher of the MLTK requires Splunk Enterprise 8.0 or higher or Splunk Cloud Platform.

The Machine Learning Toolkit requires the Python for Scientific Computing (PSC) add-on. Version 5.3.1 of the MLTK requires version 3.0.0, 3.0.1, or 3.0.2 of the Python for Scientific computing add-on.

Upgrading to a 5.3.x version of MLTK from a 5.2.x version of MLTK requires the retraining of any old models.

About the PSC add-on

Version 3.0.0 of the Python for Scientific Computing (PSC) add-on brings updates to several libraries in the package. In particular, Numpy, Scipy, scikit-learn, Statsmodels, and Networkx are upgraded to their latest available versions.

Version 3.0.1 of the Python for Scientific Computing (PSC) add-on is limited to configuration updates for deployment on Splunk Cloud Platform. Version 3.0.2 of the Python for Scientific Computing (PSC) add-on is limited to bug fixes only.

If you have any custom algorithms that rely on the PSC libraries, upgrading the PSC add-on will impact those algorithms. You must re-train any models (re-run the search that used the fit command) using those algorithms after you upgrade the PSC add-on.

Versions 2.0.2 and 2.0.1 of the PSC add-on are limited to minor library upgrades from version 2.0.0. There are no differences in functionality to version 2.0.0 of the PSC add-on.

On some Windows installations, installing PSC through the Splunk Manage Apps user interface results in an error. This error is usually benign and can be ignored. In some cases it is necessary to manually unpack the package in the apps directory to get past the error.

Splunk Cloud Platform deployments

For Splunk Cloud Platform trial and Splunk Cloud Platform, open a ticket with support and request an upgrade to the latest version of the Python for Scientific Computing add-on and Machine Learning Toolkit app.

Splunk Enterprise single instance deployments

Follow these directions for single instance deployments.

Upgrade the Machine Learning Toolkit app on your single instance Splunk Enterprise

If a newer version of the Python for Scientific Computing add-on is required for the newer version of the Machine Learning Toolkit, a message will display when you run the Machine Learning Toolkit after the upgrade instructing you to install a newer version of the Python for Scientific Computing add-on.

Update an app or add-on in Splunk Web

In Splunk Web, click the Update option on the app icon in the left-hand Apps bar.
The Update option appears when a new version of an app is available on Splunkbase.

Alternatively, you can perform the following steps:

  1. Download the latest version of the app from Splunkbase.
  2. In Splunk Web, click on the gear icon next to Apps in the left navigation bar.
  3. On the Apps page, click Install app from file.
  4. Click Choose File, navigate to and select the package file for the app or add-on, then click Open.
  5. Check the Upgrade app box.
  6. Click Upload.

Update an existing app on your Splunk instance using the CLI

Run the command line that corresponds to your operating system:

Operating system Command line
Unix/Linux ./splunk install app <app_package_filename> -update 1 -auth <username>:<password>
Windows splunk install app <app_package_filename> -update 1 -auth <username>:<password>

Alternatively, unpack/unzip the file then copy the app directory to $SPLUNK_HOME/etc/apps on Unix based systems or %SPLUNK_HOME%\etc\apps on Windows systems.

Splunk Enterprise distributed deployments

In a distributed deployment of Splunk Enterprise, update the Machine Learning Toolkit, and Python for Scientific Computing add-on if necessary, on every Splunk instance where the application is installed. The Python for Scientific Computing and the Machine Learning Toolkit should be installed on all search heads where the Machine Learning Toolkit is used.
