How to export and use a trained outmodel in Proc NNET for later use

William29 — Fri, 30 Aug 2024 02:42:03 GMT

I have used to following code to train a neural net model:

I then exported the model so that I can use it in a different sas file to score data using the following code which is part of the same file as the code above:

In a different file, I then import the model and use it to score new data using the following code:

However this generates the following error:

I have the feeling that you cant simple export and import a model generated by the inmodel statement like a normal dataset. So how do I export and import it. Different model types have a SAVESTATE statement that can be used with PROC ASTORE to properly IMPORT and EXPORT the model but PROC NNET does not have the option for a SAVESTATE statement so how can this be done?

Tell us about the SAS version you are using.
Submit

%PUT &=sysvlong4;

... and tell us what's in the log-screen.

If I look at the latest 2024.08 documentation
(https://go.documentation.sas.com/doc/en/pgmsascdc/v_054/casml/casml_nnet_syntax12.htm) , there is a

SAVESTATE Statement (to create an analytic store) and a
CODE Statement (that returns the SAS score code)

Both ways can be used to score data similar to the input data.

When i put in that code i get the following:
