Hi,

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:  
 ![image](https://global.discourse-cdn.com/julialang/original/3X/3/c/3c0032e173788ad7908588a6d3bb15f34e5e63a2.png)  
When I click “Install” a lot of text comes up in my VS Code terminal, but it seems to fail. It includes a message:

```julia
  ----------------------------------------
  Failed building wheel for pyzmq
  Running setup.py clean for pyzmq
Failed to build pyzmq

```

and ends with

```julia
    ************************************************
    Fatal: Cython-generated file 'zmq/backend/cython/_device.c' not found.
                    Cython >= 0.29 is required to compile pyzmq from a development branch.
                    Please install Cython or download a release package of pyzmq.

```

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

```julia
PYTHON=“” julia 

```

Which disables your environment’s Python, and causes Julia to install its own conda virtual environment when required by [PyCall](https://github.com/JuliaPy/PyCall.jl)

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 🙂
