missing kernel

[janxkoci]

I want to learn Julia, but she ain't making it easy.

I thought I finally set up a working Julia environment - I finally have working IJulia installation that can successfully connect to a kernel and open notebooks. The problem is, the notebooks are always starting in my home directory, instead of my working directory in terminal / Julia REPL, from which I start IJulia. This is kind of useless for any workflow.

I installed Julia as follows:

mamba create -n julia -c https://prefix.dev/julia-forge julia notebook jupyterlab catppuccin-jupyterlab
mamba activate julia

Then, in Julia REPL, I added IJulia:

] add IJulia

which worked fine (no more ZMQ compilation errors as when I used unofficial packages, great).

But when I try to start notebook() or jupyterlab(), it opens the interface in a browser tab, but shows my home directory instead of my current working directory, where I want to have the notebook files. The REPL says the following:

julia> notebook()
notebook = `/home/jena/miniforge3/envs/julia/bin/jupyter notebook`
[ Info: running `/home/jena/miniforge3/envs/julia/bin/jupyter notebook`
Process(setenv(`/home/jena/miniforge3/envs/julia/bin/jupyter notebook`; dir="/home/jena"), ProcessExited(0))

julia> jupyterlab()
[ Info: running `/home/jena/miniforge3/envs/julia/bin/jupyter lab`
Process(setenv(`/home/jena/miniforge3/envs/julia/bin/jupyter lab`; dir="/home/jena"), ProcessExited(0))

julia> pwd()
"/home/jena/Dropbox/Science/code/codes-for-life"

The Process(setenv(/home/jena/miniforge3/envs/julia/bin/jupyter notebook; dir="/home/jena"), ProcessExited(0)) lines appear after I shut down the notebook / jupyterlab, i.e. only the Info: lines are visible while the notebook is running.

Any idea why IJulia is switching my directories, and how do I stop it / stay in current dir?

After posting, I realized that maybe the notebook() and jupyterlab() functions take a dir argument - and they do! So after a few attempts I finally got what I want with:

wd = pwd()
jupyterlab(; dir = wd)

PPPS: Better yet:

jupyterlab(dir=".")

So I guess I can close this now. PS: actually nope, I see the wrong kernel, see bellow 👇

One more question, if I may - why do I not see my IJulia kernel when I just start jupyter-lab in terminal (with active env)? With R I can always just start jupyter directly, without going through REPL.

Could it be because I have another Julia installed globally from Manjaro repos? (This one is visible in jupyter, but some packages cannot be installed there, because again - unofficial. So I'd like to see the official one from julia-forge instead.)

PPS: I removed the globally installed Julia and now jupyterlab says I have no kernel, even when I start it with IJulia as above 😕 I'm lost..

Okay, I fixed everything by rebuilding IJulia, which was added to the environment toml by some previous installation. Still new to all of this, sorry for the spam.
