Import PMML model to Model Manager

valengvz — Thu, 26 Aug 2021 16:08:44 GMT

Hi there, I'm working with migration from R to SAS, the company currently has a model in R which has written with the h2o package. I know for experience that Model Manager accepts PMML models so I already did the conversion from MOJO(type of file that h2o's model export) to PMML.

When I imported to SAS I had the following message error:

This is how the PMML file looks like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<PMML xmlns="http://www.dmg.org/PMML-4_4" xmlns:data="http://jpmml.org/jpmml-model/InlineTable" version="4.4">

I don't know how can I fix this error because when I tried to load the PMML model to python the model works fine and I even made predictions.

Does someone know how can I deal with this error or if there is another alternative to work with h2o models from R in SAS?

We faced a similar issue and found out that SAS Viya only supports PMML v4.2, not PMML v4.4. The following community link discussed how to create a properly formatted PMML 4.2 for R, though you might find that PMML 4.2 might not support the model you're trying to deploy.

If this doesn't work, your options would be to

recreate your model using SAS code and deploy that
publish your R package to a supported container service

more details on the PMML implementation are in the SAS Model Manager documentation

Best of luck!

I already did that, that works with other models but not with gradient boosting or random forest. I does SAS support ensemble models via pmml?
