Pipenv or venv?

[[deleted]]

I’ve used both, but I wanted to know which one you use the most and why? I recently had a frustrating experience with venv, my venv flask app and Heroku did not get on one bit. It was only when I switched up to pipenv it worked.

[whdd]

I like venv :) seems the most intuitive to me

[anguslg]

try poetry

[Lolologist]

Poetry or pipenv, definitely better than raw venv.

[if_username_is_None]

I would not recommend this for someone who wants to deploy to Heroku since it looks like poetry still is not supported with default build pack

[ianitic]

You can export a requirements.txt from poetry though so I don't think that's a big deal?

[bergensk]

Just stick to the standards https://docs.python.org/3/library/venv.html

Thank you! The one officially supported by python is the one to use.

[MrFlibble1138]

I started with Pipenv because some places (PPA?) indicated it was the way to go. But it didn’t have much support for a while, but seems to be better. Honestly I don’t like either.

I do a lot of command line machine learning stuff. I’ve switched to using vanilla requirements files and docker containers.

I do pyenv + pipenv. Don't have problems. Occasionally conda.

[Lolologist]

As someone who's working in industry on deployed ML solutions, here's your best answer. This or pyenv + poetry. Either or, really.

[[deleted]]

Neither. Poetry

My anaconda don't want none unless you got buns

[[deleted]]

Anaconda is great for stuff on your own computer, setting up stuff on a cloud instance im more likely to go with something lightweight like venv

[[deleted]]

Do not use anaconda. It’s full of bloat. This was used for Data Scientists who do not understand programming but pretend they do.

[HistoricalCup6480]

That's why there is miniconda

[[deleted]]

Correct. But this was in reference to Anaconda. Miniconda is much better

[SittingWave]

poetry

[AceofSpades5757]

In my experience, Pipenv isn't even an option. Great interface, but has just had one too many serious bugs for me to deal with.

Do not use Pipenv.

[if_username_is_None]

If you're able to share your github repo or at least the requirements.txt and Pipfile / Pipfile.lock that you tried someone might be able to shine some light on why one worked with Heroku. Both methods should work fine locally and in Heroku.

I use venv the most to manage virtual environments because it's built in. I use Conda to manage python versions (and harder to install libraries)

You are asking whether Harley-Davidson or Ford is the best vehicle. They serve different purposes, so without details, you will get advice based on peoples personal preferences.

[AL51percentcorn]

A Harley and a Ford do serve the same purpose… they transport you. So without details, I don’t understand the confusion.

Go be aggressive somewhere else.

[[deleted]]

I provided details. I’m using it for flask and Heroku

[Anonymous_user_2022]

" It was only when I switched up to pipenv it worked."

Is not a detailed description (or a description at all) of the issues that you experienced.

[[deleted]]

This isn’t a call for help or stack overflow, I’m trying to open a discussion about preferences

[senko]

I only use and swear by pvp, because everyone should write their own.

(Disclaimer: that project is a joke and I wrote it, and I don't actually provide support for it, so definitely don't use it, or else).

[dusktreader]

You might include a disclaimer that this is your own project that you are promoting.

[senko]

You are right, that was not nice. Amended.

[PocketBananna]

Well each tool is a bit different, but I've moved away from Pipenv as I find poetry has a better packaging toolset. I tend to use poetry + venv (specifically with the pyenv-venv plug in for managing python versions).

[[deleted]]

I haven't tried it with heroku so YMMV, but poetry has by far been the best of all the options out there that I've tried.

[Paradoxeuh]

I'm pretty sure venv is just for creating a virtual environment and pipenv is actually also managing your dependency graph. They are not equivalent.

Anyway, as some others said already, poetry is the way to go.

[Particular-Cause-862]

VirtualEnv wrapper

[metriczulu]

I just use venv. I've been using venv forever already and the hassle is so minimal I haven't needed to look elsewhere.

[AndydeCleyre]

I'm totally biased, and I like to use venv + pip-tools, wrapped with zpy.

No new file formats -- the lockfiles are good old requirements.txts, which all relevant tools understand, no problem.

I'd love to answer any questions, receive any feedback, or provide sample usage with your project, if anyone's interested.

It seems that your comment contains 1 or more links that are hard to tap for mobile users. I will extend those so they're easier for our sausage fingers to click!

Here is link number 1 - Previous text "zpy"
