pyppeteer.errors.TimeoutError：超过导航超时：超过 30000 毫秒尝试将 jupyter 笔记本转换为 pdf 时

如何解决pyppeteer.errors.TimeoutError：超过导航超时：超过 30000 毫秒尝试将 jupyter 笔记本转换为 pdf 时

我使用 nbconvert 使用以下代码将笔记本转换为 pdf：

(base) C:\Users\25470\Desktop\Data Projects\Quantium Virtual Internship\Assingment 2>jupyter nbconvert task2.ipynb --to webpdf

我得到以下输出：

[NbConvertApp] Converting notebook task2.ipynb to webpdf
[NbConvertApp] Building PDF

然后这个错误：

什么意思？其他文件转换正常。 Myb 文件大小是问题，文件是 2.5mb。
