while using vscode, I noticed that pylance wasn’t running even after forcing pylance server restart. I checked the output logs and it was stuck at this line:

(10968) Searching for source files

solution

add pyrightconfig.json on project root dir.

Here is a link to github explaning about what this file is.

populate exclude field with directories that contain large, non source, etc files that you don’t want pylance to look into.

in my case, I had a directory that had no python files but a large dataset file. Adding these dirs to exclude immediately solve my issue.
