As you can see on the left of the screen, i have a python venv, but i can't get the jupyter notebook to select that venv. What can I do? The kernel button on the top-right (where it says "Python 3.12.7") doesn't detect it either

when you click on the button in the top-right, what happens?
errant hedge
when you click on the button in the top-right, what happens?
it asks whether i want to use a python kernel or jupyter server, and if i select the first, then it just asks me to either create a new .venv or select a default global installation
west jasper
🤔
I chose the top option (I forget what it was), then it gave me the chance to choose an existing virtualenv, and the relevant one was at the top
errant hedge
if it just allowed me to place a certain one, it would be doable
maybe it has to do with how i created the env? with the terminal command?
west jasper
why not choose the one that it shows as "Recommended"?
That's what I did, and it worked fine
errant hedge
id rather not use a global one, and instead have a venv for each project... At least that's what out teacher told us is best
west jasper
but
errant hedge
and the recommended one doesnt even exist lol
west jasper
if you choose the recommend one you will not be using "a global one"
what happens when you click that line anyway?
errant hedge
it selects the kernel, but when i try any cells it says that "it failed to start as the environment isn't available"
west jasper
🤔
errant hedge
but thats okay
lemme jsut restart the notebook
now there isnt even a recommended one xD
west jasper
so, I've created an empty folder. I copied some random notebook into it. I "pointed" VSC at that notebook, and now I see this
which seems reasonable.
errant hedge
thsi is what appears for me
west jasper
Yeah "Create Python Environemnt" sounds like the right choice
errant hedge
so i must use the env it forces me to...
west jasper
🎉
west jasper
so i must use the env it forces me to...
dunno what you mean by that
when you choose "Create Python Environment", it ... creates a virtual environment, and then uses that.
which is a good thing.
errant hedge
yeah
but then i cant move that one around? I dont want it to stay where it did, although when i move it around it says it no longer exists
west jasper
yeah you shouldn't move virtualenvs around. But why do you want to? Just create it where you actually want it.
[I'm not sure that you can't move virtualenvs around; I've just never done it]
errant hedge
yeah you shouldn't move virtualenvs around. But why do you want to? Just create...
it automatically creates it on the bigger folder, when i want it on the one holding the notebook, but it seems vsc just detects the one in the immediate folder
this does work:
but it didnt when i had the big folder opened
west jasper
big folder?
no idea what that means
when I did it, it created the virtualenv exactly where I'd expect: in the folder that I had open in vsc (which was the folder with the notebook in it)
errant hedge
sorry im not explaining myself that well. I mean the folder containing the folder that has the notebook
errant hedge
when I did it, it created the virtualenv exactly where I'd expect: in the folder...
yeah, i had a full university folder opened, so it created it somewhere else
west jasper
I'm so confused
here's what you should do
- figure out where you want the venv
- get the notebook, and whatever else you want, into that folder
- open vsc in that folder
- have vsc create the venv there
errant hedge
yeah me too... Ignoring that, now with the .venv working somewhat properly, it says that i cant pip install cause "externally-managed-environment"
errant hedge
here's what you should do
* figure out where you want the venv
* get the noteboo...
thank you

sounds like you're using Debian
errant hedge
sounds like you're using Debian
yeah, ubuntu
west jasper
ok well that's normal
errant hedge
is that aproblem?
west jasper
that's a sign that you're not using a virtualenv
errant hedge
but... it says its using one?
west jasper
I didn't know VSC ran on ubuntu though
errant hedge
west jasper
your images aren't showing up 😐
errant hedge
oh
west jasper
just piles of poo 🙂
west jasper
I'd type type -a pip at that terminal
the presence of (.venv) in the prompt isn't a guarantee that everything is properly set up (although it'd have fooled me, too)
:-) 2025-02-13T12:29:39-0800 [x]$ source .venv/bin/activate
(.venv) :-) 2025-02-13T12:29:44-0800 [x]$ type -a pip
pip is /private/var/folders/b0/_p0c_57s5n90cy4njdgd8vhw0000gq/T/x/.venv/bin/pip
that output is correct
errant hedge
ill try it after dinner, thank you
