I am using pylance for vs code and it works really nice, except that since I use it, when I try to check code from an installed library, I can get only to the stub, I think generated by pylance.
For example, the information shown about the function:

Or, crtl + click on the function brings me to the .pyi stub, which at
~/.vscode-server/extensions/ms-python.vscode-pylance-2020.11.0/dist/bundled/stubs/pandas/io/parsers.pyi
I can't find a way to navigate to the actual code (of pandas in this case).
If I deactivate Pylance and use Microsoft as language server by setting "python.languageServer": "Microsoft", in setting.json, the navigation to the library works fine.
Is it possible to navigate to the actual code with pylance active?
OS: Ubuntu 18.04
Visual Studio Code: Version: 1.50.1
Pylance: v2020.11.0
I had the same issue and realized I was using Docker. So I set up virtualenv and installed Django using pip. Then I switched Python interpreter in the bottom-left corner of VS Code and it started working.
I know this is a specific case but I hope this answer helps someone in the same problem.
