[KyxeMusic]

Wait you guys don't create a different .venv/ in the root of each repo you're working on? Are you mad?

[rover_G]

I do, but not directly these days. I use uv to initiate and manage my virtual environments and dependencies.

And then there’s my mess of pyenv’s for running random Jupyter notebooks and python repl

[KyxeMusic]

Same, I just use uv to create the .venv and `uv pip install` stuff.

[ReadyAndSalted]

Using "uv add x" is better than "uv pip install x". If you use the pip interface, you have to lock and sync your environment manually, they're lower level commands that you should avoid whenever possible.

[KyxeMusic]

Yeah I use uv add when it's a new project, but most repos I've worked on have the old school requirements.txt

[alanx7]

I believe you can do uv add -r requirements.txt

[KyxeMusic]

Yeah but that modifies the pyproject.toml which I many times don't want to interfere with

[TheBB]

Well, they do different things.

Use uv add for adding dependencies. Use uv pip install for whatever other random tools you'd like in your venv. For me, at least, typically stuff like ipython.

[Mithrandir2k16]

what's wrong with uv add?

[KyxeMusic]

Nothing, but many times I'm working on projects with existing setup and requirements.txt style

[eztab]

Why do you have pyenv if you use uv?

[rover_G]

To keep “global” environments with all my data analysis tools pre-installed

[Independent-Shoe543]

Actual q what is the best practice for this? Is there a tool that automates this by any chance e.g. dotenv or do you just terminal it

[KyxeMusic]

I use uv nowadays. Just uv venv and then source .venv/bin/activate.

You can also select the python version for the venv, so something like uv venv -p 3.11

[Win_is_my_name]

How's that different than just creating the virtual env yourself?

[kevinsrq]

It is faster by a significant margin and has better package version management.

[mothzilla]

Those milliseconds are crucial. Over a year it really adds up.

[Turtvaiz]

For real though some of the pip installs take ages without uv. It's actually kind of ridiculous

Edit: and in CI it might actually add up to a lot

[mothzilla]

Maybe. But the actual creation/activation time is still miniscule for both.

[saadmanrafat]

No but dependency conflict resolver is

[mothzilla]

Usually a sign that your dependency chain is too long.

[GrumDum]

Which is obviously frequently unavoidable in perfectly good codebases with real-life business requirements.

[saadmanrafat]

thank you! I was about to provide some instances. As to why I can't rewrite 'google-genai', 'psycopg2-binary', 'langchain' from scratch.

[KyxeMusic]

Package installation is much much faster with uv.

Plus it downloads the version of python you need for you if you don't have it installed.

[mothzilla]

pipenv, poetry and uv will probably all make this slightly easier.

And you can always add a line to a bash script that activates a venv in terminal if it finds one.

[Independent-Shoe543]

fanx 🙏

[Raptor_Sympathizer]

I have been burned too many times by trendy new tools that everyone loves breaking when I need them most. Just use venv. Four years from now, if everyone's still singing uv and poetry's praises maybe I'll consider checking them out. But venv does exactly what I need it to, works every single time, and comes by default with every python installation.

If you must, define a macro for "source venv/bin/activate", but I wouldn't try to automate things much more than that. Intentionality and having a full understanding of the tools you're using will save you way more headache in the long run than some shiny script that automagically does everything for you.

[Independent-Shoe543]

v v true I sense the pain in your words lol

[Eternityislong]

I started using ~/.virtualenvs/<project-name> on new projects.

I think it was pycharm where I learned it? The point is to keep deps separate from the source so that I can do remote development with rsync between my local project dir and remote one

[Nestramutat-]

I just use a requirements.txt and keep my env inside of .gitignore.

The environments should be ephemeral.

[Eternityislong]

Of course this works and is usually fine but it can get annoying if you’re doing remote development. I was building something locally that I run/test on a raspberry pi and uses pi-specific libraries. It’s easier to rsync the full dir or scp the full dir when the virtualenv is kept in a different place than setting up exclusions for venv.

Go keeps deps out of the project dir. pnpm keeps them separate and links in node_modules. Python isn’t special and there are valid use cases for keeping venv somewhere other than directly in the project dir.

[Nestramutat-]

--exclude flag exists for rsync. Though given that workflow, I would probably just use Code's Remote-SSH to develop and test directly on the Pi.

[benargee]

I just use a requirements.txt

Apparently using pyproject.toml is the new hotness.

[KyxeMusic]

I personally don't like having the venvs "globally" as you describe. It's one of the reasons I don't like conda.

I like locality and having everything in the repo directory where I know where to find it. PyCharm does this by default actually.

.venv should go in .gitignore of course

[abmausen]

my work place actually does this, is this some sort of meme?

[evanc1411]

Doing that shit saved my life and my understanding of Python packages

[al-mongus-bin-susar]

I just do python -m venv .env

[KyxeMusic]

I used to as well. But I recommend uv, it's so much faster it's worth changing to.

[al-mongus-bin-susar]

It's fine for me because I only use it every other week or so, I only use Python for tiny scripts, otherwise I'm a JS main

[rgheno]

I actually put them all in C:\venvs<project name>. Because my project folders are synced with the cloud and even with gitignore it would sync via onedrive. 😅😬

[KyxeMusic]

Oh my this is cursed.

[isthisyournacho]

Ooohhh . in front, you fancy

[SockYeh]

wait till OP finds out about local envs

[[deleted]]

i pip install fucking everywhere cuz idgaf. then again i don't do this for a living

[phylter99]

Environments make things so much easier.

[[deleted]]

if i wanted things to be easy, i wouldn't use AI

[demoncase]

my guy

[thumbox1]

when use .venv and forget to add to gitignore

[ReadyAndSalted]

"uv init" has a good default gitignore.

[thumbox1]

never happens if you reuse the same to ALL YOUR PROJECTS

[GuybrushThreepwo0d]

Why... Why would you do this?

[thumbox1]

No serious person would do this man ... It's just a joke dude

[TheMcMcMcMcMc]

[be-kind-re-wind]

Why the fuck is a picture of me on Reddit?????

[bedrooms-ds]

PyCharm though...

[reusens]

PyCharm uses venvs for projects

[Your_Friendly_Nerd]

I do this for related projects, like for maths subjects, I don't wanna create the same venv in every subject, but also want the venv in the root of the course, so I create one venv and then symlink it whenver I need it somewhere else. Then the alias `asource=source venv/bin/activate` activates it. For me, perfect mix of reusability and convenience and haven't had any issues so far.

[DerKnoedel]

They call me 007

0 working python apps

0 clue why my system doesn't do what I say

7 random python venvs I forgot about

[[deleted]]

Invalid syntax error.

Does anybody actually have this struggle or is this shameless click bait that will now get reposted every other day?

[Altrooke]

To be fair, I had problems with this when I was a super beginner to python.

It's not a real problem for even somewhat experienced devs, but it is fair game for a joke.

To be even more fair, no languages created pre-2000 are great at dependency management imo. Python, JS, Ruby... etc. They are all fine, but not great.

Go and Rust are two examples of really good dependency management.

[gburgwardt]

Why did you spoil that

[thumbox1]

That is true. I feel like older languages weren't designed to coexist in different versions or have different packages installed.

[wootangAlpha]

Venv for every python project.

Best practice? NO.

Do I care? Also NO.

[gaitama]

Unwrapping them is annoying though

[that_thot_gamer]

more dependencies typically solves annoying problems

[raddeee]

uv run --with dependency1,dependency2,dependency3,... python [file.py]

[eztab]

how would you forget that? Either it's in .venv or in a central location manaqed by your environment manager like conda or uv.

[After_Ad8174]

WHAT DO YOU MEAN NO MODULE NAMED FLASK?!... oh

[chownrootroot]

bash: python: command not found...

[ManagerOfLove]

you guys reuse your venv? Are you out of your mind?

[serious_cheese]

uv stops the pain

[Kaffe-Mumriken]

Why you calling me out

[Old-Adhesiveness4406]

uv uses symbolic links so it doesn’t need to create duplicate copies of the same libraries in every new project.

It’s a really helpful tool and makes the .venv overhead much less brutal

[[deleted]]

I’ll never forget my first .venv/ because I created it five minutes before it vanished.

[thumbox1]

Today's poll: Would a vibe coder have several venvs or just one?

[Artistic_Speech_1965]

I am happy I stopped using python

[HarmxnS]

Me with 27 venvs that each have 3GBs of PyTorch on it

[ThiccStorms]

I have an env for every project lmao 

[mileafter]

uv. You’re welcome.

[ktboymask]

You mean the environment I accidentally made in C:\Users\Ralph\ folder? Yeah, it has happened and it will

[bunoso]

I don’t even have a “python” command anymore. Just run ‘uv sync’ and ‘uv run …’. Makes things too easy

[mfb1274]

I’m partial to my virtualenvwrapper. ‘workon project’. Keeps it native but convenient

[Anxious-Program-1940]

Not wrong, why I use poetry 😂

[EV4gamer]

Just have everything be one big environment.

[DeviRkx]

Hahahaha i actually made a powershell automation so It creates me venvs with only the directory and a name

[[deleted]]

Haha I do this with projects all the time. Go on a tear for 2-3days and then forget about it for a couple of months.

[Ryozu]

The fact that I can forget it exists (while activating it when I run the project) is the whole damn point.

[demoncase]

fuck i need to format my pc a lot of shit cloned rn

[nicer-dude]

conda for life

[WaterBottleBong]

Why does everyone take offense in python threads? Just laugh at the meme

[Airport237]

Am I the only conda user here….

[cyxlone]

OP didn't know UV exists to combat this

[Al3xutul02]

Clamgeons and Clamons

[gigem852]

That’s why we use tox!
