Numpy/MatPlotLib reported as missing, but code works

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://video2.skills-academy.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:

207204-2022-05-31-19-26-27-pythonapplication2-microsoft-v.png

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

    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

    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.

    Best Regards,
    Tianyu
