Numpy/MatPlotLib reported as missing, but code works

Question

I am trying to swap to VS for my Python work, rather than PyCharm, as I use it for everything else.
Going through the VS/Python tutorials ( i.e. in the https://learn.microsoft.com/en-us/visualstudio/python/tutorial-working-with-python-in-visual-studio-step-05-installing-packages?view=vs-2022 series)

I can run the program in the screenshot, but Numpy & MatPlotLib come up with the green squiggly line:

As I said, the program runs fine, so I guess that this isn't a problem, but I'm generally paranoid about warnings that I don't understand
I've tried swapping the default environment to Anaconda and creating a new project, uninstalling and reinstalling the two packages and creating a new environment with just the two packages with no change.

What exactly is the problem here?
Cheers for any advice

Answer 1

Hi @Andrew Milburn

As your running this on your local machine you simply need to install the required libraries

In you code install numpy and matplotlib

To Install python libraries https://docs.python.org/3/installing/index.html

Use the following command above the current code

pip install numpy
pip install matplotlib

in the code before your load the libraries

@Andrew Milburn

Ok so check the environment is the actual activated environment

See https://learn.microsoft.com/visualstudio/python/selecting-a-python-environment-for-a-project?view=vs-2022

Answer 3

Hi @Andrew Milburn ,

Welcome to Microsoft Q&A forum.

If you try to reopen/reload your project, will it work?

Reopen: File > Close Solution > select this Python project and reopen it.

Reload: right-click this Python project > Unload Project > Right-click it again > Reload Project.

• Update:

Sometimes, resetting VS, restarting VS or repairing VS may work.
