CORR_MATRIX() error

edited October 2019 in General Discussion

Hi,
I'm trying to use CORR_MATRIX (simplified example, I realize CORR would work for just 2 columns) as follows:
select CORR_MATRIX("hour_7", "drops") OVER () from (
select * from (select apply_one_hot_encoder(* using parameters model_name='test_encoder', drop_first='false') from test) as Q1
) as Q2;

but getting this error:
ERROR 3457: Function CORR_MATRIX(int, int) does not exist, or permission is denied for CORR_MATRIX(int, int)
I'm running
vsql version 09.02.0007, built for Linux64
From JB Favre's vertica docker container
https://hub.docker.com/r/jbfavre/vertica/
The docs say CORR_MATRIX is a 9.2.x feature, but I can't find details more granular than that.
Any ideas?
Thanks,
Michael

  • But as you indicated, just use CORR(), since you're just analyzing two columns.

  • I have this error too:
    Vertica 9.3
    variant1. SELECT corr_matrix(prescr_amount,total_pat_flow,target_pat_flow) OVER() FROM Baikal_Progressa_table;
    ERROR: Function corr_matrix(float, float, float) does not exist, or permission is denied for corr_matrix(float, float, float)

    variant2.
    SELECT corr_matrix("prescr_amount","total_pat_flow","target_pat_flow") OVER() FROM Baikal_Progressa_table;
    ERROR: Function corr_matrix(float, float, float) does not exist, or permission is denied for corr_matrix(float, float, float)

    variant3.
    SELECT corr_matrix('prescr_amount', 'total_pat_flow', 'target_pat_flow') OVER() FROM Baikal_Progressa_table;
    ERROR: Function corr_matrix(unknown, unknown, unknown) does not exist, or permission is denied for corr_matrix(unknown, unknown, unknown)

    Where my mistake??

  • Your first option should run.
    SELECT CORR_MATRIX(Sepal_Length, Sepal_Width, Petal_Length, Petal_Width) OVER() FROM iris;
    Perhaps it's a problem with the function. You might need to reinstall the packages associated with that function (probably the machine learning package). https://www.vertica.com/docs/9.3.x/HTML/Content/Authoring/InstallationGuide/Upgrade/PostUpgrade/UpgradingandReinstallingPackages.htm?zoom_highlight=uninstall package

  • Thanks!
    What is the name of the machine learning package? Where can I see it?
