A suggested fix to #2550.
The proposed solution adds a
_transformed_
buffer to all of the priors ofTransformedDistributions
(LogNormal, HalfNormal, HalfCauchy), as their original parameters cannot be saved tostate_dict
. Thus these parameters will be saved and loaded from state_dict, and sets the value of the parameters of the corresponding base distributions.Added some tests for these methods as well, hopefully they are sufficient.
