Gaussian Mixture Model Enumeration in Guide with New Data

I’ve tried to follow the procedure of the GMM Example and wanted to evaluate Classification of new-data by the learned GMM model, using Enumeration in the full_guide() described in the tutorial.

I obtained an error, which I have raised as a github-bug, though I’m not certain if its truly a bug, or if I have missed out on something.

I would really appreciate it if you could guide me on using the Enumeration in Guide methodology for a new-dataset.
