[pymvpa] LinearSVM Classification Warning

[Yaroslav Halchenko]

it means that 

 Classifier LinearCSVMC(kernel_type='linear', svm_impl='C_SVC')
 wasn't trained to classify labels Set([3.0]) present in testing
 dataset. Make sure that you have not mixed order/names of the
 arguments anywhere

Also test if you don't have a mix of float and int labels in your
datasets (as I remember you are manually composing those).
