I am trying to get the Machine Learning toolkit (and of course Python tools for machine learning) installed on our clustered instance. I have gotten both the apps distributed to the search heads using our deployment server. I am trying to get Python tools for machine learning distributed to the indexes. I got the app installed on our cluster master and moved a copy of the app to the master-apps folder, but when I go to Validate and Check restart in the UI it fails validation. Any help or insight in to this would be very helpful. I have apps in master-apps for all of our iis, sql, windows, and custom logs but adding the python tools invalidates the package.
