IndependentMultiVariateDistribution and serializing models

[Amanda-MCN]

When using IndependentMultivariateDistribution for the roi priors, I am getting and error when trying to save the model usingthe serialisation rather than pickle. The save as .binpb works fine when I use the same distribution type (i.e. LogNormal) for all priors. I can save it as a pickle without any issue. (These screen shots are from a modified Colab for Meridian Getting started). Am I building the priors ok as the model builds ok and using the priors.

Hi @Amanda-MCN ,

Thank you for contacting us!

We've identified the root cause of the serialization issue when saving models with IndependentMultivariateDistribution priors as .binpb and have implemented a fix. This fix will be included in our upcoming release. You can track its status in the CHANGELOG.md under the [Unreleased] section.

Hope this helps.

Thank you,
