Cela semble être un bug lié à l'utilisation de 'verbose' et' nfolds' en même temps. À court terme, vous pouvez supprimer l'option 'verbose' et suivre la progression en redirigeant votre navigateur vers localhost: 54321 et en utilisant H2O Flow. –

Supprimer le verbose = TRUE a corrigé le bug. Merci –

Pour répondre officiellement à cette question, comme l'a dit Branden ci-dessus, c'est un bug (et peut être évité en ne définissant pas l'option verbose). Le bug est suivi dans le H2O-3 JIRA here et il y a déjà une demande de tirage avec un correctif here.
