Blaze with Scikit Learn K-Means

Question

I am trying to fit Blaze data object to scikit kmeans function.

from blaze import *
from sklearn.cluster import KMeans
data_numeric = Data('data.csv')
data_cluster = KMeans(n_clusters=5)
data_cluster.fit(data_numeric)

Data Sample:

A  B  C
1  32 34
5  57 92
89 67 21

Its throwing error :

I have been able to do it with Pandas Dataframe. Any way to feed blaze object to this function ?

Answer 1

I think you need to convert your pandas dataframe into an numpy array before you fit.

from blaze import *
import numpy

from sklearn.cluster import KMeans
data_numeric = numpy.array(data('data.csv'))
data_cluster = KMeans(n_clusters=5)
data_cluster.fit(data_numeric)
