Jupyter notebook python3内核仅连接某些文件

Question

我刚刚重新安装了 anaconda。

当我尝试打开一个新的空白文件时，内核连接并且没有出现导入错误。 但是当我尝试打开一个其他人可以打开的更大文件时，内核永远无法连接，我尝试通过 anaconda 终端启动它，这是我收到的错误消息：

ImportError: cannot import name 'Pdb' from 'IPython.core.debugger' (/Users/pierre/opt/anaconda3/lib/python3.7/site-packages/IPython/core/debugger.py)

在一个空白的新笔记本中，我可以正确地从 IPython.core.debugger 导入 Pdb，同时还可以导入标准的 python pdb。

规格： 我在更新的 MAC os-x 和 Windows 10 上有这个错误，jupyter notebook python 3 内核在我的 mac 上工作，直到我尝试为 vsc python 代码单元安装内核。 我使用 seaborn 作为附加库。

首先检查它打开的环境是否正确（通常当你打开一本新的空白书时，它打开的环境是base），是否安装了该库的所有模块。
