Description

I fitted the mediterranean data set ``ds = argo_loader.region([-6, 35, 30, 46, 0, 1000, '2012', '2013']).to_xarray()`` to a model using k=8 and temperature as feature and I obteined the following spatial distribution of classes:

![ArgoMed_map_labels_EX](https://user-images.githubusercontent.com/59824937/87797689-5907b080-c84b-11ea-956d-76d5c13cf339.png)

Some minutes ago I fitted the model again with the same dataset and the same model inputs and I obtained a different result:

![ArgoMed_map_labels_EX(2)](https://user-images.githubusercontent.com/59824937/87797885-9a985b80-c84b-11ea-9d8f-c36480ecf8a9.png)

The spatial distribution of classes is different: in the fist example we have 2 classes in the western basin and in the second example there is only one class in the western basin.

Why using the same dataset and the same model the results of fitting are different? Is it related to the convengence of the model?
