Extracting the updated prior parameter values

[Mojo_ild]

Also, another question, in the second error,

@Mojo_ild

I know the error is caused by the random definition but what could be my mistake here?

Side question:

With regards to the naming in the priors, is there a way when you get to S2_P_Bayesian_Interface you can rename the variable name of the priors from e.g. sigma_0 to sigma_P after the from_posterior ?

I looked at the code again and looked at the link that you sent. I found out could it be because of the naming it caused this error (Am I right)? I vaguely remember that either trace or tensor can be used to rename the variable.
