Is there a way to get IJulia to work with a poetry environment?

Question

I have a local Poetry .venv with Jupyter already installed. I am trying to get IJulia to work with this Jupyter installation as opposed to installing it through Conda. But I am not having much success.

This is what I've tried so far:

$ poetry shell
$ julia
julia> ]
pkg> activate MyEnv
julia> ENV["JUPYTER"]=".venv/bin/jupyter"
julia> ]
pkg> add IJulia
julia> using IJulia
julia> notebook()

Then it still asks me if I want to install Jupyter with Conda. And I do not. What am I missing here?

Answer 1

I tested on Ubuntu running on WSL2 and the following works for me.

1. Have poetry along jupyter installed

2. Check that whereis python resolves to poetry Python installation

3. Start Julia:

    $ poetry shell
    $ julia
   

4. Run the following code:

    using Pkg
    pyt = split(read(`whereis python`, String))[2]
    ENV["PYTHON"]=pyt;
    Pkg.build("PyCall")
    Pkg.build("IJulia")
   

5. Now you are done so you can do:

    julia> ENV["JUPYTER_TOKEN"]="mysecret";  # Jupyter password
    julia>  notebook(dir=".")
    [ Info: running `/home/ubuntu/.cache/pypoetry/virtualenvs/ubuntu-zk_aSFMD-py3.10/bin/jupyter notebook`
   

Here is my installation:

Answer 2

Just launch the notebook separately from the command line.

You don't need the notebook() function in Julia to do it — that's only there as a convenience for people who installed Jupyter through IJulia, and will only work if you told IJulia where Jupyter was (via an environment variable) when IJulia was built (via build IJulia at the pkg> prompt).

(PyCall has nothing to do with this.)
