say "Train dimensions: $rows, $cols";
my $booster = XGBoosterCreate([$dtrain]);
for my $iter (0 .. 10) {
XGBoosterUpdateOneIter($booster, $iter, $dtrain);
}
my $predictions = XGBoosterPredict($booster, $dtest);
# say join "\n", @$predictions;
XGBoosterFree($booster);
XGDMatrixFree($dtrain);
XGDMatrixFree($dtest);DESCRIPTION
