Known issues

The following are known issues in the Splunk Machine Learning Toolkit version 5.2.0.


Date filed Issue number Description
2020-12-22 MLA-3965 Error in 'fit' command: Error while fitting "DensityFunction" model: Domain error in arguments.
2019-12-17 MLA-3701 Search bars in Assistants will not display more than approximately 500k rows

Workaround:
This is mostly a visual issue - the actual number of results the Assistant will use when fitting a model is not affected.
2019-12-11 MLA-3686 MLTK Assistants do not support quote characters in field names

Workaround:
Use the "rename" or "eval" command to rename the field prior to using it.
2019-10-09 MLA-3559 Loading settings from experiment history while in the Learn stage will lead to warnings, even when inputs are correct
2019-08-30 MLA-3423 Add a warning message when kfold_cv is set to number greater than half of the datasize
2019-07-12 MLA-3237 Anova table does not allow some special characters in formula so in field names also

Workaround:
Rename your field names before running "score anova" if they include one or more of those special characters:

 (r'[&%$#@!`\|";<>^]')

 

 

2019-03-28 MLA-2965 "Edit Job Settings" does not work in Assistants
2018-09-24 MLA-2547 Experiments can't be renamed until they have been filled and saved

Workaround:
Load the Experiment, fill all necessary fields, and save it. You'll be able to rename the Experiment in the Save dialog.
2018-06-12 MLA-2258 TFIDF returns a vague error message when the "token_pattern" parameter is invalid
2018-04-18 MLA-2147 search.log does not show tracebacks on Windows on Splunk 7.1

Workaround:
The user can still look at the logs on windows in mlspl.log which captures the traceback. However, many users may not have access to mlspl.log (as it is indexed in the _internal index which normal users don't have by default). If this is the case, they will need to ask their Splunk administrators for access to this index.
2017-08-25 MLA-1916 Uncaught StatsModels error with ARIMA order=0-2-0
2017-02-28 MLA-1670 "Outliers Over Time" plot doesn't display any data if the _time field does not contain a Unix timestamp.
2016-12-13 MLA-1485 In the Forecast Time Series assistant, forecasting a very large number of points may cause the browser to crash.
