Net 7.0

Hi.

I have download Your example and works like a charm.
But, copyng and paste the code into a wpf net 7.0 app

Microsoft.ML.Probabilistic.Compiler.CompilationFailedException
HResult=0x80131500
Message=MessageTransform failed with 1 error(s) and 0 warning(s):
Error 0: This model is not supported with ExpectationPropagation due to Factor.GaussianFromMeanAndVariance(double sample, double mean, double variance). Try using a different algorithm or expressing the model differently in

Any hint?

I know it is an old example, but is the onlyone i have find.

TIA

Hi Arnh!

The reason my project runs is probably it pulls the older Infer.NET framework. Once you use the my Infer.NET model code with newer Infer.NET framework, the code might break. Try locally to use up to date Infer.NET framework and see if the error is still there.

I also encourage to post this question (provide model) in issues in the official dotnet/infer repo. People there have been very responsive and helpful.
