如何让python识别安装在虚拟环境中的模块？

Question

I'm having trouble getting python in vs code to work properly. There were problems for a while (i dove right in with a workspace folder) so I decided to set up everything from scratch by starting a new project/workspace folder.

so far I've been having a few issues. The latest is this: despite creative a virtual environment as instructed on the vs code website, I can't get python to recognize that I've already installed the modules I want to use.

How do I fix this? (please see attached picture.

towards the bottom you can see that the virtual environment already has matplotlib, but python wouldn't recognize the module anyway

Answer 1

1. Create your virtual environment (eg I used venv module to create a virtual env called TEST : $python3 -m venv TEST
2. From VS code go to Command Palette and type Python: Select Interpreter

And then you can choose the location of the desired interpreter (in my case the one from TEST virtual environment

3. You can always test your virtual environment from the terminal, eg TEST env

Bash

From Cmd/Powershell normally you should run:

TEST\Scripts\activate.bat
