How Can I get the cluster number or class for an specific data point?

[bennsandoval]

After:
som = somoclu.Somoclu(n_columns, n_rows, data=data, maptype="toroid", initialization="pca")
som.train()
som.cluster()
som.view_umatrix(bestmatches=True)

How Can I get the cluster number or class for an specific data point like data[0]?

After calling som.cluster, the 2D array som.clusters holds the cluster information for each node. Match that with som.bmu, and you have the cluster number for each data point. Something like this:

k = 0  # The data instance you are interested in 
som.clusters[som.bmus[k, 1], som.bmus[k, 0]]

Awesome!! Thanks.
