Hi @grechasneak, a NotImplementedError indicates that the functionality does not exist for the type of Copula you're using.

I would recommend referring to the API docs for Vine Copulas. In the docs, I don't see any method called probability_density. Did you meant to use a different method such as get_likelihood?

Alternatively, if you think probability density is something that's missing, we could turn this into a feature request for adding such functionality. We prioritize feature requests based on demand and the importance to your projects. So any other information about your project will be useful. For example, what is the goal of the project? Are you trying to predict something for the selected weather?
