E:\anaconda\lib\site-packages\nbformat\__init__.py:129: MissingIDFieldWarning: Code cell is missing an id field, this will become a hard error in future nbformat versions. You may want to use normalize() on your notebooks before validations (available since nbformat 5.1.4). Previous versions of nbformat are fixing this issue transparently, and will stop doing so in the future.
validate(nb)

validate_nb(model['content'])
请问这应该怎么解决？
我检查了端口是否占用，显示没有，更新了jupyter，仍然这样。
