You may search for settings about additional import search resolution paths:

"python.analysis.extraPaths": [
    "path1",
    "path2",
],

Please have a try.

More information view Pylance Settings and Customization.

That is a Pylance error.

You can create a pyrightconfig.json file at the root of your workspace and define the files to be exclude-d from analysis or completely ignore-d:

{
    "ignore": [
        "**/*.ipynb",
    ],
}

You can even list up specific filenames:

{
    "ignore": [
        "notimportant.ipynb",
        "test.ipynb",
    ],
}

Historical Notes:

It initially didn't work for Jupyter Notebooks (.ipynb):
https://github.com/microsoft/pylance-release/issues/2135

This happens because pyright doesn't see the file as a "*.ipynb". The file is being preprocessed (to combine all of the cells) in the notebook by the VS Code Python extension, and the resulting combined file is then passed to pyright for analysis.

The pylance team is actively working on changing the way this works. I'm going to transfer this bug to the pylance-release repo so it gets the attention it deserves.

That Github issue has since been resolved the fix was deployed as part of pylance 2022.8.51: https://github.com/microsoft/pylance-release/blob/main/CHANGELOG.md#2022851-31-august-2022-prerelease

Notable changes:

• ...
• Bug Fix: Ignoring *.ipynb files does not work (pylance-release#2135)

If it somehow still does not work, check the version of pylance on your VS Code.

1. Find the error-message you want to modify/disable in the Pylance's Diagnostic Severity Rules (in my case "reportMissingImports")
2. Modify settings.json with "reportMissingImports": "none" (see diagnosis reporting levels in Pylance's Settings and Customization)

The entire JSON-code to be inserted into the settings.json is:

"python.analysis.diagnosticSeverityOverrides": {
    "reportMissingImports": "none"
}

As an aside, if you want to be at least informed about unused imports, you can use:

"python.analysis.diagnosticSeverityOverrides": {
    "reportUnusedImport": "information",
    "reportMissingImports": "none"
}

PS: regarding the settings.json - location

Along with the global settings.json there are also local versions in your VS-Code-projects' parent directories. In the following, example paths are provided based on my Windows 10 - OS:

• global: C:\Users\user.name\AppData\Roaming\Code\User\settings.json
• local: .vscode/settings.json

These local project settings override the global ones, if desired.
