Custom algorithms and PSC libraries version dependencies
Running version 5.3.3 or higher of the MLTK requires Splunk Enterprise 8.1.x or higher or Splunk Cloud Platform.
The Splunk Machine Learning Toolkit requires installation of the correct version of the Python for Scientific Computing (PSC) add-on from Splunkbase.
Version 4.0.0 of the PSC add-on is only available for MLTK version 5.3.3. Users upgrading to version 4.0.0 of the PSC add-on must follow some additional installation steps. See Install version 4.0.0 of the Python for Scientific Computing add-on.
Before you upgrade to a new version
Any algorithms that have been imported from the PSC add-on into the Machine Learning Toolkit are overwritten when the MLTK app is updated to a new version. Prior to upgrading the MLTK, save your custom algorithms and re-import them manually after the upgrade.
If you have written 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.
Algorithms are stored in $SPLUNK_HOME/etc/apps/Splunk_ML_Toolkit/bin/algos
on Unix-based systems and %SPLUNK_HOME%\etc\apps\Splunk_ML_Toolkit\bin\algos
on Windows systems.
