Why do you want to convert libsvm to another structure?
I don't quite get it.
If you want to use examples: scikit learn has included datasets that can
be directly loaded. I think this section should help:

The problem is that I tried using load_svmlight_file with in particular RBF
parameters example

and I get a lot of
That uses the Boolean indexing function of numpy arrays iirc

Suppose you have
x = np.array([1, 2, 3, 4])
Then
x 2 = [False, False, True, True]
Using boolean indexing
x[x 2] = [3, 4]

Thank you guys it makes more sense now.
I slightly changed the code to fit my data ( I have 6 features)
I got then an error message saying :
File plot_rbf_parameters.py, line 109, in module
Z = clf.decision_function(np.c_[xx.ravel(), yy.ravel()])
File
X_2d = X[:, :6] if the data is formatted correctly. Its rows by cols and
then slicing. The numpy docs should help

Ronnie,
This is exactly what I did and that's what shows in the error message saying
X.shape[1] = 2 should be equal to 6, the number of features at training time
The training was made successfully, best parameters sent to output successfully
but then I think it is a bug when rendering the
could you by chance upload a part of your data if not all of it / a
representation or the like?
