How to fix "Error: Direct kernel connection broken"?

Question

I've been using Jupyter notebooks in VSCode and it has worked fine for several months. Yesterday, I cleaned out a ton of my storage because it was cluttered and overfilled. Now my VSCode will either return an "Error: Direct kernel connection broken" or it will not install any of my previous packages. Can anybody help me fix this issue?

Answer 1

Switch kernel from .venv to default then switch it back again. then run all cells, not the current cell.

Answer 2

I also stuck with the same problem :

1. Try to do this

pip install ipython

pip install ipykernel

2. If you already have a kernel installed, upgrade it

pip install --upgrade ipython

pip install --upgrade ipykernel

It works for me
