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
Could you try to reinstall the pyzmq module?
pip uninstall pyzmq
pip install pyzmq==19.0.2
I got the same error message because the jupyter package was missing in my selected environment.
pip install jupyter
resolved the problem for me.
From the official VS Code documentation:
To work with Python in Jupyter Notebooks, you must activate an Anaconda environment in VS Code, or another Python environment in which you've installed the Jupyter package.
A workaround would be to run the kernel in a separate terminal (using the jupyter notebook command), and to connect to that kernel from VS Code (Click on "Jupyter Server: local" and choose the kernel running on localhost from the list).
