Transfer multiclass question to regression question

[BrunoQin]

Recently I have read the paper and do some experiment by convgp. This is an excellent repo and I have learned much from here. I have such a challenge when I use this:

I have a lot of ocean data which is 2D, which is from Jan. and Dec., and I want to use these dataset to build a regression model, for example, I use the 2D data from Jan. to predict an index calculated by 2D data from Dec. such as Nino Index.

I know that there is a complete task named GPflowRegressionTracker, and I just modified the code from other script, transfer GPflowMultiClassificationTracker to GPflowRegressionTracker, by the way, I also changed some parameter name making it be able to trained.

I don't know whether I get the right way, because I cannot find any examples about regression in repo, and could you give me some advice?
