MLTK published models differ from SPL created models

[joshiro]

On Splunk Enterprise on prem 9.0.1, after using Smart Forecasting (MLTK 5.3.1), and publishing the recently created model, the apply command returns error "Error in 'apply' command: list assignment index out of range".

But the same model created using SPL with fit command works fine.

Here is the traceback:

Anyone managed to get the publish option in MLTK working?
