Splunk Machine Learning Toolkit: Added CorrelationMatrix algo but cannot import name BaseAlgo

[lloydknight]

Hello,

So I followed this doc below:
http://docs.splunk.com/Documentation/MLApp/2.2.0/API/CorrelationMatrix

Now I am getting this error upon following the example search:

Error in 'fit' command: (ImportError) cannot import name BaseAlgo

Below is the splunkd error in debug mode:
05-12-2017 16:22:38.972 +0800 ERROR ChunkedExternProcessor - stderr: (ImportError) cannot import name BaseAlgo

Things I already checked:
- Installed Python for Scientific Computing properly with respect to its OS architecture and not renamed it.
- Splunk runs with the same user who installed the app.

Any idea guys?

Much appreciated!

Hello @lloydknight

Can you confirm which version of MLTK and PSC you are using? As well as Splunk Version?

While in the MLTK, go up to Help > About:

The custom algorithm documentation you link only applies to version 2.2.

Best,
Xander

CorrelationMatrix is now working. I cannot mark your answer as an answer since you made it a comment.

[aljohnson_splun]

I converted it to an answer - glad to hear that it fixed your issue.

Holy?! Why didn't I check the version requirement! Will execute this later and provide an update. Thank you!
