iPython笔记本错误 - Notebook JSON无效:u'execution_count'是必需属性

我在运行我的iPython笔记本时遇到以下错误,并且想知道是否有人可以提供帮助.

我曾尝试浏览以前的帖子,但找不到答案.noteboook最终在Web浏览器上运行,但错误仍然出现.

控制台出错:

有任何想法吗？谢谢!

更新

实际上这个错误只发生在我从PyCharm编辑器运行jupyter/ipython笔记本时.如果我在网络浏览器上运行它,错误就会消失.看起来PyCharm的笔记本兼容性仍然存在问题......

在笔记本上使用PyCharm后我遇到了同样的问题.

我可以通过简单地重新启动内核,清除所有输出并保存笔记本来使错误消失在浏览器中.

(内核/重启和清除输出)
