[FIXED] Failed to start the Kernel - Jupyter in VS Code

Issue

I am trying to use a Jupyter notebook for some Pandas in VS Code. I set up a virtual environment venv where I installed Pandas and jupyter. I always did it like this and it worked fine. But suddenly it does not work anymore. Code with error message

Solution

Could you try to reinstall the pyzmq module?

pip uninstall pyzmq
pip install pyzmq==19.0.2
