How to score data using a modelStore model with code?

1dsspntdSSsr — Mon, 21 Mar 2022 19:59:18 GMT

I want to reference a model that exists in mu modelStore library but I can't get it to work. I'm using the model name taken from model manager AstoreMetadata.json as shown on the picture below. The code I'm trying is shown below the picture.

Viya version 2021.2

Release 20220317

proc gradboost data = caslib.casdata
	inmodel=ModelStore.modelname noprint;
	output out=caslib._scored_gbm;
run;

proc astore;
   score data=caslib.dataset
         rstore=ModelStore.modelname
         out=caslib.astore_out;
quit;

The error I get is that modelStore has more than 8 characters.

Is there a way to reference the model saved in ModelStore to score data?

Hello,

You can have CASLIBs with a name exceeding 8 characters in length, but it's not very practical !

See here :

CASLIB= data set option for caslibs longer than 8 characters

Good luck,

According to the documentation, RSTORE points to a CAS libref, I'm missing a libname statement in your code.

As @sbxkoenk states you can have CASlibs with longer names than 8 chars, but SAS librefs are limited to 8 chars.

Thank you for your suggestion. ModelStore is a default caslib, I wouldn't have created a libname that is obscurely supported but the SAS folks thought this was somehow helpful.

In any case, I had seen the post you referenced and that option doesn't work on what I'm intending to do. That is why I shared my code. I'd appreciate if suggestions are not just a quick google search but a thought out and tried response. I have done the google searches already.

Same response as above as your suggestion was already placed.

OK.

You can always reach out to SAS Technical Support in your country if the "communities" do not help you fast enough or well enough.

SAS complains about exceeding 8 positions, but I am wondering if the underlying reason is not << 'ModelStore' not being known as CASLIB >>.

See :

Add ModelStore and ModelPerformanceData Caslibs to a CAS Server

Good luck,

Thank you again for your reply. As the picture I posted shows the model is already registered in the ModelStore caslib. Thus showing that ModelStore is in fact a caslib and that I had access as I registered the model there.

I think you want to do this:

libname mycas cas caslib=ModelStore;

Then use mycas where you have caslib and ModelStore in the proc gradboost/astore calls.

Thanks @WendyCzika .

It's probably as simple as that indeed. This is one to remember !

@1dsspntdSSsr : I hope you haven't given up yet and that this suggestion / solution will still come in handy.

Thanks,

Koen
