converting CSV dataset to LIBSVM format

Hi,

I have tied the “save as” option but the new version of weka 3.60 doesn’t have the option to save as LIBSVM.

How is it possible to convert a comma separated value dataset to LIBSVM format using WEKA?

Kind Regards

I assume that you're talking about the "save as" option in the Explorer.

Not all savers support all attribute types. The LibSVM saver only
supports nominal and numeric attributes (and needs a class attribute
set). If your dataset contains string attributes or has no class
attribute set, you won't be able to save it with this saver.

Cheers, Peter
