Oracle DVD Machine Learning error

Content

Hi everyone,

I have just upgraded my Oracle Data Visualization Desktop to the latest version to make use of the new 'Machine Learning' option. After the installation of Oracle Data Visualization Desktop I installed DVML.

If I follow this video now:

If I want to execute the data flow, I get the following error message:

Traceback (most recent call last):

File "C: \ Users \ USER \ AppData \ Local \ Temp \ 2 \ DVDesktop \ servers \ obis1 \ tmp \ nQS_PAF_8996_3_44714521.TMP", line 91, in <module>

model = obi_create_model (dat, columnMetadata, args)

File "C: \ Users \ USER \ AppData \ Local \ Temp \ 2 \ DVDesktop \ servers \ obis1 \ tmp \ nQS_PAF_8996_3_44714521.TMP", line 48, in obi_create_model

model = obipy.tools.linear_regression.create_model (dat, target, args)

File "C: \ Program Files \ Oracle Data Visualization Desktop \ Oracle BI1 \ bifoundation \ advance

Does anyone know a solution here?

I installed DVML in \DVML folder and was able to use ML model

you have to install DVML first,  you can search "DVML" in start menu.

Yes, we did install DVML. Question, did you have to install Advanced ANalytics for this or not? If you will notice, the last line mentioned something about Advanced Analytics.

Hi,

I am also getting the same error. Anybody find a solution?

I suspect you're actually getting a different error as you're using a different model ( naive bayes and not linear regression).  My advice is the same though - to look at the full error message in the logs.

Hi,

That's just because the actual error message is truncated in the viewer and so you are not seeing the actual reason.  You will find that full dump in the log files - and I think the one you'll want is the obis1-diagnostic.log

I have installed AA and then DVML.  Please try installing AA first and then DVML.  Hope it should help fix this.

I got the same error today.

I uninstalled the DV, deleted all the files in the tmp directory location, and did a fresh install of the DV. Once that completes, re-install the DVML, and it should execute. Your install  is still referencing the old PAF file from the prior one. Somehow these are left orphaned out with the upgrade.

Hope this helps! Good luck!!
