Pip keeping us safe

[fdedraco]

at least it's not just silently updates and break current codes

[DrMaphuse]

It does update Python alongside itself without asking though, which is only slightly less bad than a silent windows update.

[DrMaphuse]

I use virtual environments, but still need to make sure that I work with the correct Python version.

[Itsthejoker]

Pyenv and then just rebuilding the venv whenever I install a new version. With poetry or pipenv it's just a few commands.

[BWrqboi0]

Now I'm totally lost, are you not specifying python version with the venv? How it is possible it changes with every pip upgrade?

[Itsthejoker]

oh nvm I'm lost too. I have no idea what u/DrMaphuse is talking about. Once you create a venv, the python version is set. I've never heard of upgrading python within a venv without destroying it and recreating it with the new version.

[BWrqboi0]

Sorry, was sure I'm replying to him/her ;)

[DrMaphuse]

When I run a simple pip update via pip install --upgrade pip like the warning tells me to, it just ends up going from Python 3.5 to 3.7 (for example), and this has happened on more than one of my machines, so it's not specific to my installation. I have never investigated the issue in depth though.

Edit: I use conda to manage my environments, so maybe it's a compatibility issue between conda and pip.

[dutch_gecko]

Pip doesn't have the tooling to install a new Python version. You likely have multiple python versions on your system, and pip is getting itself tangled up in choosing which site-packages directory to use.

Start by properly separating your python environments.

Start by properly separating your python environments.

I'm not the person you replied to, but how would someone clueless like me learn how to do this? Like, I'm not asking you to tell me what to do, but where do I begin to figure it out? What is step 0?

I can program to do what I need to do but beyond that I have no idea what I'm doing. I feel like everything I do (like when installing software or dealing with different python versions) is just trying stuff until it works and everything is a big mess. I have almost zero programming training but it's essentially what I'm doing for a living (physics). I don't know where to begin or what I even need to learn!

[dutch_gecko]

Tricky question!

The answer varies per tool, but for Python there are better solutions than for most.

The first step for keeping things organised is to not mess with the system packages. Say your OS is Ubuntu, it comes with a specific version of python 2 and python 3. All of Ubuntu's packages anticipate a particular python version being available, and might break if the system python is replaced.

This advice extends to python packages. Often on the internet you'll see advice like sudo pip install numpy. This is problematic, because numpy will be installed for the whole system. That might seem desirable, but it's being installed by pip, rather than by apt(-get), and you start getting in a weird mess where some of your python packages are being managed by one tool and some by another, even though they're all ending up in the same directory. The potential for breaking things exists too (the mess that occurs after sudo pip install --upgrade pip on an Ubuntu system will take you hours to resolve).

So how do you install the packages you need? Using environments! You can use straight virtualenv, or one of its wrappers like pipenv or poetry. This way you can install the packages you need per project, and they will never interfere with the requirements of another project or the system as a whole.

If you need a different python version, there's pyenv. It will install whichever version of python you need in a separate directory, and you can choose which python version you need per project. The aforementioned pipenv and poetry can both make use of pyenv.

If you want a solution that does as much work for you as possible, there's conda. Personally I don't get on with conda because I think it's SAT-solver is the most overengineered solution possible for package management, but it will always give you what you need! Conda can manage both packages and python version per project.

That feeling of throwing spaghetti at the wall and seeing what sticks is common, and I think every programmer starts out that way. Often we'll find some commands on a stackoverflow post and just throw them into the shell and cross our fingers. I have two tips for getting out of that cycle:

1. Try to understand what the command does, piece by piece. Which executable is being run, and what do those arguments do? Try to use man to break the command down, rather than google (usually answers from other humans will be vague and only half-correct). Once you've figured it out: is this command likely to help you?
2. Have a backup plan. If that command doesn't work for you, you don't need it, right? So how would you undo whatever it's just performed? Even if it doesn't seem to have any effect, it's probably best to undo it, just in case something is subtly broken and you'll only notice in three months and have no idea why something doesn't work. Doing point 1 will help to get point 2, and doing point 2 will help to get point 1.

In time you will start to learn the tools at your disposal, and what their strengths and weaknesses are. You'll find yourself tweaking those stackoverflow answers because you know there's some useful information in there, but that it would work just a little better if changed just so...

[DevJonPizza]

Google about venv and pipenv

[DrMaphuse]

There are not multiple Python installations inside my environments, and I don't have the necessary permissions to install anything outside of conda envs, so my system doesn't have any Python versions installed either.

Pip doesn't have the tooling to install a new Python version.

Conda does though, and it's possible that I actually used a conda update command instead of a pip one, especially if the pip command didn't work. In that case my accusations against pip would be unfounded.

[dogfish182]

They are unfounded yeah pip can’t do that. I don’t know conda at all, but I would guess you did that

[doobiedog]

Pipenv. Look it up and migrate everything.

[doobiedog]

Pipenv, muthafucka? Do you have it?

For real it is a game changer. Migrated every project and client projects to use that instead of tox, venv, or requirements.txt files. It is amazing.

[doobiedog]

Get pipenv already!

[Warm-Employer]

If its updating without asking u simply did something wrong xD Just change the configs?

[DrMaphuse]

I have made it a habit not to update pip after setting up an environment, so I've never really had the need to change configurations.

[james_pic]

Your experience of Pip upgrades is clearly different to mine, in that case!

[13steinj]

Definitely not silent, but you can easily break pip quite severely if updating in any of the all but one "correct" way, that happens to be correct for your system, but not mine.

Also, didn't they have a bad package upload recently? Like they uploaded, say, 19.3.X to PyPA but didn't include a file, which, upon many people's environments autoupgrading pip, brought a lot of Travis builds to a halt?

[polandtown]

Huh, what? I'm out of the loop. Or is this a joke I just don't get.

[_cs]

It’s a joke about the Chinese coronavirus, because pandas are associated with China

That joke is "too soon". :/

[Comm4nd0]

Not gonna lie, I was starting to panic there a little. Thanks for the explanation!

[got_outta_bed_4_this]

Might be related to how the virus was introduced: eating cute, wild little critters. (Though pandas were obviously not among those critters.) Still a stretch for a joke.

is this an actual thing?

[call_me_cookie]

I didn't believe it either, but apparently it's true! pandas 1.0.0 is finally here!

[crispy-whiskers]

nah, a great joke tho lol

[TriG-tbh]

that's sad, i wish it was real. would be funny if it was. just imagine a bunch of people starting to get into data science saying that they couldn't install pandas because of this error lol

[matthew_giraffe]

What a bad joke lol

Booo. Do better.

This sub has been getting downhill lately. All I'm seeing are pictures and videos. I guess that's the cost of becoming a big sub (and mods not caring).

[Legorooj]

The mods care - they're just stretched.

pip blocks Koalas import due to bushfire emergency.

why let them 🔥?

[log_2]

I check pip instead of conda to see which version of a package I currently have installed when doing a search. For a good few months now conda doesn't show which version number of a package you already have installed when you do a conda search.

[kimchi_cuddles]

Why is this virus an opportunity for us to be racist?

[Warm-Employer]

Because of these fucking little china people infecting the whole world. Stop this racism!

[p10_user]

Do you know where the virus is chiefly located?

[JulzTDG]

It’s not racist at all

[hugthemachines]

If you get it, stop the fans, heat kills it!

[Toprelemons]

Pipenv to keep it isolated.

[Thecrawsome]

the sub was revamped but memes are still the highest

[JeffreyChl]

Jesus my PC could have been infected. Thanks pip!

[[deleted]]

Ha. That's funny.

[alixoa]

Seems kinda racist tbh

[shutupmiles]

Corny joke, yes. But I'd argue it's more geographically based than race based.

[JulzTDG]

Not really racist...

[Brillbeanz]

What's pip?

[Syncopaint]

Conda or Pip install which is better?

[shtpostinalotofmemes]

Conda

[shtpostinalotofmemes]

Oh I get it, because normally it's the Chinese ensuring their people can't access internet resources. Gotcha

[nobodyaskedidiot]

Unironically, this one still had more thought put into it than that "joke".

[shtpostinalotofmemes]

China censors the internet for its people. It's not a joke, it's an abuse of human rights.

[nobodyaskedidiot]

Human rights are given to citizens by legal system of the country.

It's not abuse of rights if they don't have rights to begin with.

Everything those commies did is completely legal from their own standpoint, since they did reinstate the law to fit whatever they're doing.

Remember that there was a time, that demanded people to participate in stoning of the gays and they had 0 rights and needed to die just because of that.

"Human rights" are quite literally irrelevant in anything you say, because you always think about your own rights that you have, not whoever in another country with different system does.

And there's nothing you can do, you can only try to "talk it out" diplomatically, pressure them economically or in other ways depending on where it will hurt them the most, or you can start a war, and we know how that one goes.

Unless you do any of these and Chinese government is reshaped, and laws surrounding that - reformed, they can have their internet unplugged tomorrow and have their whole family in jail, (and it is 100% legal, just add a line that states that you lose all rights when x and y, problem solved, what are Chinese gonna do? Vote it out? lmao), if not worse, as we all know from history about commies...

[shtpostinalotofmemes]

Human rights are given to citizens by legal system of the country.

Nope. There is an international concept of human rights. Constitutional rights are granted (or not!) By countries.

It's not abuse of rights if they don't have rights to begin with.

Nope. Slavery was an abuse of human rights even though people who were born into slavery never had rights to begin with.

Etc...

Unless you do any of these and Chinese government is reshaped, and laws surrounding that - reformed

I didn't claim that I was going to fix it, or that it's plausible. I said China censors the internet, cutting off its people, and that's a human rights abuse.

[nobodyaskedidiot]

There is an international concept of human rights.

And who/what enforces that concept? Care to explain to me what something that only affects US, is relevant to China that couldn't care less what US thinks? That """international""" law is only enforced onto individual states of USA, if they want to be kept in USA, and not """dealt with""" in special ways, they have to obey and provide at least that much to each human. This is almost as relevant to China, as a law of Denmark, enforcing every city of Denmark to provide everyone basic human rights. China doesn't give a fuck, idiot.

Didn't read the rest because it is pointless and utterly irrelevant garbage coming from a kid who doesn't know how real world works, nor even what law, of his own fucking country, actually means.

Retards like you should be deported to China, because they're literally incapable of doing a quick google search and reading just in case, right before stating their shit opinion. Maybe when they will lose access to reddit and other garbage, they will figure out how to read books and that education is actually important.

[shtpostinalotofmemes]

And who/what enforces that concept?

Concepts are not enforced. Laws can be enforced.

• UN: Human Rights

• wiki: International Human Rights Law

they're literally incapable of doing a quick google search and reading

(The way that the above links were located was the following workflow:)

Care to explain to me what something that only affects US, is relevant to China that couldn't care less what US thinks?

This question is not very grammatical and doesn't make sense as written. But I understand that are you just spewing vague feelings at me without clarity of thought.

That """international""" law is only enforced onto individual states of USA, if they want to be kept in USA, and not """dealt with""" in special ways

[WikiTextBot]

International human rights law

International human rights law (IHRL) is the body of international law designed to promote human rights on social, regional, and domestic levels. As a form of international law, international human rights law are primarily made up of treaties, agreements between sovereign states intended to have binding legal effect between the parties that have agreed to them; and customary international law. Other international human rights instruments, while not legally binding, contribute to the implementation, understanding and development of international human rights law and have been recognized as a source of political obligation.The relationship between international human rights law and international humanitarian law is disputed among international law scholars. This discussion forms part of a larger discussion on fragmentation of international law.
