Description

As reported on otb-users:

Hi,

Since OTB 6.6.0-Win64 release, the app Train Vector Classifier seems to have a bug when running with libSVM classifier and especially when options "Paramaters optimization" and "Probability estimation" are enabled.

With previous version (6.4.0), the algorithm works properly (it displays the confusion matrix and performance index) but since last version 6.6.0, the optimization process runs infinitely without stopping and without displaying performance index. I suspect an issue because if I disable those options, the app properly works.

But I really need those options to classify my orthotoplans though an automated processings chain. Awaiting a fix, I continue to use OTB 6.4.0.

Sincerely, Etienne.

Steps to reproduce
