Python script is keep running on global environment in linux even the virtual environement is active

[niranjan-pattanaik]

I have installed fastapi with in my new virtual environment which i can confirm with pip list but when i try to import fastapi with from fastapi import FastAPI it shows module not found error. Where as i have checked my python interpreter path with which python which again redirects to the same correct virtual environment path and again to confirm with pip list it also shows module name but somehow while running it keeps running on the global environment.
Installed packages in my virtual environment :

Did you select the virtual environment in VS Code itself? And when you run which python and pip list, are you doing that from the terminal within VS Code and after we have activated the terminal for you, or are you doing it separately from VS Code?

Yes I have selected the virtual environment itself. I can change my virtual environment also i can check and confirm the environment i am running with which python and pip list without any issue. But when i run my script in my selected virtual environment it will show ModuleNotFound Error as it is for some reason being running in my global environment. Even when i change my interpreter manually this issue persist and i am not able to run my script in desired environment.

Unfortunately that doesn't guarantee anything if activation didn't work out. It also doesn't necessarily align with what's been selected in the extension itself.

Can you run the below script from the extension (you can use the run button or however you're running your code) and verify it matches what you expect?

import sys
print(sys.executable)

And how are you running your code? Are you using the run button? And I assume you don't have the Code Runner installed?

A screenshot of the exact results would probably be helpful at this point.
