Question

我创建了一个简单的内核，用于包装单元格的内容，并在jupyter上的特定数据库中将其作为SQL执行。

当我在安装了jupyter笔记本并执行任务的jupyter笔记本上打开内核时，内核完全可以正常工作。

但是当我尝试使用nbconvert执行笔记本时，它会引发以下有关内核在响应之前死亡的错误。

Exception in thread Thread-31:
Traceback (most recent call last):

    raise RuntimeError('Kernel died before replying to kernel_info')
RuntimeError: Kernel died before replying to kernel_info

关于什么可能导致这种情况或我可以从哪里开始寻找答案的任何想法？

Jupyter内核死于nbconvert，但不是死在jupyter上
