Cannot run Notebook from within VS Code "Running cells with 'Python 3.8.0 64-bit' requires notebook."


I have a VS Code installation where I open a jupyter notebook I have previously created in jupyter lab. When I opened it I needed to install a python extension. I can edit cells, but when I try to run anything I get an error message:
When I click “Install” a lot of text comes up in my VS Code terminal, but it seems to fail. It includes a message:

  Failed building wheel for pyzmq
  Running clean for pyzmq
Failed to build pyzmq

and ends with

    Fatal: Cython-generated file 'zmq/backend/cython/_device.c' not found.
                    Cython >= 0.29 is required to compile pyzmq from a development branch.

I really don’t know what this means.
(I could include more if useful, but there’s a lot of it)

Either way, this process seems to fail, and when I try to run something again, the result is similar. Clicking “Change interpreter” gives me various python options, but none seem to help. There is some indicator suggesting I am running the notebook in Julia 1.6.1.

I run VS Code 1.59, and have the Julia, Jupyter, and Python extensions isntalled.

Some suggestions.
Create a blah.jl file to trigger vs-code to fire-up Julia. It then may know enough to find the Julia kernel for the notebook.

Or, exit vs-code and start the REPL from the command-line like

PYTHON=“” julia 

Which disables your environment’s Python, and causes Julia to install its own conda virtual environment when required by PyCall

Activate a local environment from the package manager
] activate .
Within the REPL package manager

] add PyCall, IJulia

If you exit the REPL and then, from the command line, start vscode local to your working directory
% code .
I think it will activate the environment you created above, which should have everything.

This is a bit of a thought experiment, and I’m not at a terminal, so no guarantees

Unfortunately it didn’t work, but thanks for the help still :slight_smile:
