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......
今天，当我尝试编写一个对 ipython 脚本进行半自动编辑的脚本时，我遇到了同样的问题。
您可以在 python 中逐行读取文件，然后执行 str.replace('"execution_count": "null"', '"execution_count": null') 并将输出写入新文件。
然后您可以在 ipython 笔记本中打开新文件。它为我解决了问题。毕竟，ipython 笔记本文件只是一个 json 文件（只不过是一堆嵌套的字典和列表）。
