Unfortunately libsvm does not provides this in its public API (svm_train). However it is computed internally in the SolverInfo structure which is allocated by the svm_train_one function. It should be printed on stdout using the info function at the end of the fitting process though. By reading the wrapper code I cannot find where the libsvm info output is disabled in scikit-learn. It would be great to be able to turn it on using a verbose flag for instance.
