I had this problem recently and after trying many solutions, what worked for me was a combination of

"python.analysis.exclude": [
        "**/site-packages/**",
        "**/data/**"
    ],

and

"files.watcherExclude": {
        "**/.git/objects/**": true,
        "**/.git/subtree-cache/**": true,
        "**/node_modules/*/**": true,
        "**data": true,
    },

Not sure which of the two was required, but finally my laptop stopped hyperventilating for no reason. In case it is useful to anyone

Here is how I solved this issue:

Go to File > Preferences > Settings > TYPE "python.language server"

If set to 'Microsoft' change your language server to 'Pylance'

Python: Language Server
Define Type of the Language Server
SELECT: Pylance

Reload your Visual Studio Code Try importing your libraries causing the issues again:

import numpy as np
import pandas as pd

I had the same issue; the only solution that worked for me was to open settings.json (ctrl + Shift + P) and change

"python.languageServer": "Microsoft"

to

"python.languageServer": "Pylance"

Then one gets a pop-up that asks whether one wants to reload the window which one should confirm by pressing "OK".

Then everything works normally again (IntelliJ, autocomplete etc).

As @Vasco pointed out in the comments Microsoft is no longer supported as explained in this thread.

Can solve this by either disabling the extension as suggested in previous answers, or excluding large directories (e.g. containing data) from its search path, by adding to your workspace settings an python.workspaceSymbols.exclusionPatterns key, like so:

settings.json:

{
    "python.workspaceSymbols.exclusionPatterns": [
        "**/site-packages/**",
        "your_pattern_or_directory_to_exclude"
    ]
}

See also the vscode extension docs.

High memory usage： https://github.com/Microsoft/python-language-server/issues/832 Jedi is an autocompletion tool for Python that can be used in IDEs/editors. Jedi works. Jedi is fast. It understands all of the basic Python syntax elements including many builtin functions. So you can switch Jedi instead of Python Language Server.

Process:

  1. set "python.jediEnabled": true

  2. disable the Visual Studio IntelliCode plugin

  3. delete the .vscode directory

This seems to have fixed it for me: https://github.com/Microsoft/vscode-python/issues/4990#issuecomment-477628947

You can disable the new Python Language Server by opening settings in VSCode (Ctrl+, ) and set "python.jediEnabled": true. Then reload the window and/or restart VSCode.
