이것은 'verbose'와 'nfolds'를 동시에 사용하는 것과 관련된 버그 인 것 같습니다. 단기적으로 브라우저를 localhost : 54321로 지정하고 H2O Flow를 사용하여'verbose' 옵션을 제거하고 진행 상황을 추적 할 수 있습니다. –

verbose = TRUE를 제거하면 버그가 수정되었습니다. 감사 –

브랜든이 말했듯이이 질문에 공식적으로 대답하려면 버그입니다 (verbose 옵션을 설정하지 않으면 피할 수 있습니다). 버그가 H2O-3 JIRA here에서 추적되고 이미 수정 요청 here이있는 풀 요청이 있습니다.
