Hi Sheila.
It would help if you could say what the difference between the two
datasets is.
Given the name "iris.scale" I would assume that it is somehow scaled,
either using zero mean, unit variance, between 0 and 1 or l2 normalized.
Have you tried using Scaler on the data to see what you get?
Cheers,
Andy

Hi all,
I am trying to read libsvm format data 'iris.scale' (from
http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/multiclass/iris.scale
<http://www.csie.ntu.edu.tw/%7Ecjlin/libsvmtools/datasets/multiclass/iris.scale>
) as
from sklearn.datasets import load_svmlight_file
X_train, y_train = load_svmlight_file('iris.scale')
I thought this will give same format as
from sklearn import datasets
iris = datasets.load_iris()
Though y_train is same format as iris.target but X_train is not in
same format as iris.data !!!
How can I read a libsvm format file same as datasets.load_iris()
Thanks
