.arff files with scikit-learn?

Question

I would like to use an Attribute-Relation File Format with scikit-learn to do some NLP task, is this possible? How can use an .arff file with scikit-learn?

Answer 1

Solution with scipy.arff

Code:

from scipy.io import arff
import pandas as pd

data = arff.loadarff('file.arff')
df = pd.DataFrame(data[0])
df.head()

Answer 2

I really recommend liac-arff. It doesn't load directly to numpy, but the conversion is simple:

import arff, numpy as np
dataset = arff.load(open('mydataset.arff', 'rb'))
data = np.array(dataset['data'])
