Reshaping a Pandas dataframe into a sparse matrix

	import pandas as pd
	import scipy.sparse as sps

	df = pd.DataFrame({'tag1': ['sean', 'udi', 'bogdan'], 'tag2': ['sean', 'udi', 'udi'], 'freq': [1,2,3]})
	# tag1 -> rows, tag2 -> columns
	df.set_index(['tag1', 'tag2'], inplace=True)

	mat = sps.coo_matrix((df.freq, (df.index.labels[0], df.index.labels[1])))
	print(mat.todense())
