Need help with downloading python packages to a venv

[fresh locust]

I downloaded the packages to a venv and it shows up in the Lib folder but when I try to import it, it marks it as not found, I have the environment set to the right python version

[bronze anchor]

Are you sure you activated the venv and/or selected the venv in your ide?

If you want to use the venv in when running the code, you need to activate the venv with this command:

# windows (bash)
venv\Scripts\activate.bat

# windows (powershell)
.\venv\Scripts\Activate.ps1

# macos/linux
source myfirstproject/bin/activate

As for the IDE, it's generally located in the bottom right. You will see the enviroment its using. You should see something like that:

Python 3.13.5 (venv)

[signal jacinth]

just use uv

[bronze anchor]

I don't think it's the issue

I feel like their IDE is not set to the right environment

[signal jacinth]

yea just use uv lol it'll auto pick up the right venv

or just uv run like everyone else

[bronze anchor]

Most text editor should auto select the right venv too. And activating it isn't super complicated

[fresh locust]

I did activate my venv and set the environment to that venv but when I open a python file and import things I downloaded in the venv it won’t show up and labeled not found

I don’t know if it had to do something with the directory I’m downloading it onto

[bronze anchor]

No you don't really have to do anything, pip should download it at the right place. Did you run pip install <your package> beforeyou enabled you venv? You need to activate it first then run pip install

[fresh locust]

I downloaded my packages with pip and it did download in the right place which is the Lib file of the venv

[bronze anchor]

Can you send a screenshot of the error you're getting and your editor's settings where you get that error?

[fresh locust]

Yeah sure let me get my vs studio up

[bronze anchor]

Visual Studio or VS Code? If you're going to write something in Python I strongly suggest VS Code over Visual Studio. I know it's confusing but there's a difference

Also, when I think about it, did you put your venv folder in your project folder? It generally needs to be within your project folder

[fresh locust]

Visual studio

It’s weird becuase I did it on another pc and it worked but not for mine

[bronze anchor]

[fresh locust]

Also when you run the tes.Python file it shows up the right errors

[bronze anchor]

It's hard to say, I would checkout this https://code.visualstudio.com/docs/python/environments

[fresh locust]

But it dosent show that langchain is imported

[bronze anchor]

It's hard to read, can you send a screenshot plz https://www.take-a-screenshot.org/

[fresh locust]

Here wait I just snipped it from my pc

[bronze anchor]

Mmh try re-running pip install langchain.

[fresh locust]

Ok lemme try

[bronze anchor]

If you look correctly at the error, it's langchain_anthropic that's missing

Are you sure you're installing the right package?

[fresh locust]

It says that all of it is satisfied

I only need langchain for this, the Anthropic is another model

[bronze anchor]

Also again, send me screenshots. Photo of screens are horrible to read.

[fresh locust]

Sorry bout that

[signal jacinth]

the anthropic stuff is in a different package

[fresh locust]

When I run the file it has the right errors showing that it is detecting the packages but it won’t detect it when editing the file

[bronze anchor]

What where's saying is that you're missing another package. The module that cannot be imported is called langchain_anthropic which is a different package. I believe you need to install the langchain-anthropic package

pip install langchain-anthropic

[fresh locust]

Yes but I’m using langchain.agents, the packages are installed it’s just it isn’t detecting it in the file but when ran it detects it

[bronze anchor]

It's likely because you didn't set up the correct venv in your ide. Go through this (https://code.visualstudio.com/docs/python/environments) and if it doesn't fix the issue we can look at it more with you

[bronze anchor]

Did it work? If it works you should see the correct venv path when you over over the python environment at the bottom right

[fresh locust]

Ok so I just deleted the venv and setup a new venv environment but now when I’m downloading langchain it says error externally managed environment

[bronze anchor]

You probably forgot activate it before running pip install

[fresh locust]

It’s already activated

Should I use pipx?

[bronze anchor]

You don't have too. I'm pretty sure that you just didn't activate the venv

[fresh locust]

It’s activated it has the .venv next to my name

I don’t know why it keeps showing as externally managed

[bronze anchor]

This shows that you created it not that you activated it

python -m venv .venv
source .venv/bin/activate
pip install ...

[fresh locust]

I used vs studio create virtual enviorment next to select interpreter

Also I’m using WSL for the terminal, I don’t know if this affects anything when downloading packages

[bronze anchor]

Look at the error message. It gives you step to fix it

Also, I indeed just realized that you're on windows and using WSL

[fresh locust]

So should I just create a python virtual environment?

[bronze anchor]

Do you need wsl? If you don't need it don't use it

[fresh locust]

I do need it since I don’t use windows at all and it’s just easier to use

Power shell

I’m try making another venv using python venv .venv1 outside of my current venv

I will see if that works

[bronze anchor]

Anyway, the fact that you've been using wsl and windows at the same time and specially using the ide to generate the venv is your problem

[fresh locust]

Ok so I can download langchain using python venv but can’t using vs studio venv?

[bronze anchor]

Your ide is running on your windows and when you click on generate venv it generates a venv for windows. But, you're trying to use it from wsl which is linux

[fresh locust]

I don’t know why this is

[bronze anchor]

You can you just need to generate the venv through wsl and not the ide

[fresh locust]

Oh ok so my vs studio venv is connected to my windows

[bronze anchor]

try that in your wsl terminal

[fresh locust]

I tried that and downloaded langchain and it worked

[bronze anchor]

It shouldn't throw any erros

[bronze anchor]

Okay but did you install the other dependencies? Earlier we told you that you had other missing packages

[fresh locust]

So I’m guessing when I make a venv through my wsl it stays on the Linux folder and when I try doing the same thing with the IDE venv it stays on my windowsnfolder

[fresh locust]

The other packages were just add ons, the reason why it didn’t work is becuase they were requesting a llm, I did that on purpose becuase I don’t want to mix up stuff and I just wanted to see if the correct errors showed

Ok lemme try importing the langchain now

[bronze anchor]

You might want to check this out too https://code.visualstudio.com/docs/remote/wsl-tutorial

Also, next time you ask for help it's a good idea to mention things like "I'm using wsl"

[fresh locust]

Yooooo it worked thank you very much, that article was rlly helpful, I got the imports in and everything is right as it should be, I didn’t know that wsl wouldn’t automatically connect to vs studio but I live and learn. Thanks very much!!!

[bronze anchor]

Awesome, well done!

PS. As I said, next time you ask for help don't forget to include those kind of details, it would have saved us a lot of time : ) I recommend that you take a minute to read #📄・posting-guidelines. They are not just for the server but to ask good questions in general.

[fresh locust]

I will make sure next time, thanks for the help
