Unable to Import in VS Code

问题:

I'm new to python and I've been using VS code. Right now I'm working on a Thompson Sampling problem that requires numpy and matplotlib. I've imported both libraries but VS code is giving the error unable to import. I know I have to install with PIP, and I have seen other solutions about changing the Python path through the json. but I'm afraid to do that because I don't want to mess up my text editor. Can someone walk me through what I am supposed to do? I haven't seen any simple tutorials on setting up VS Code for python. I'm hoping this will help other people too! I have the extensions Python and CodeRunner installed in VS code. Thank you!

6.type pip install python.
7.type pip install numpy.
8.type pip install matplotlib.

If you're using Python 3, the issue is most likely that when you installed numpy and matplotlib you used the pip command, which will only install them for Python 2. To install the libraries for Python 3 just use the pip3 command in place of pip.

this happened to me when installing numpy but after i restarted VScode it fixed it's self. if that didn't work check that the package is installed with: pip list in the command prompt.
