[Help] Auto completion only working in some of the editor tabs

[tddschn]

I had ~10 python files opened in different tabs in VS Code, and auto completion only worked in some of them, and sometimes none of them, which happens more often. Workplace symbols were not built.

Let's say two of the tabs are named tab A and tab B, auto completion works in tab A but not in B. When I switched to tab B and Reload Window, auto completion worked in tab B but stopped working in tab A, while auto formatting on save was working in both of the tabs.

I tried reloading window and restarting VS Code but the problem remained, and I couldn't find anything useful in the extension outputs.

What's your language server set to? And is there any helpful information in the Output panel for the language server you are using? And are you using a single workspace or a multi-root workspace? And I assume the files are marked as being of the type "Python" in the right side of the status bar?

What's your language server set to?

Microsoft.

And is there any helpful information in the Output panel for the language server you are using?

This is the full output of the language server after reloading the window and editing python files for a few hours:

And are you using a single workspace or a multi-root workspace?

It's a multi-root workspace with 2 root dirs, and some of the files I opened are outside of these 2 dirs.

And I assume the files are marked as being of the type "Python" in the right side of the status bar?

Yes, they were :) (And syntax highlighting and auto formatting all worked great.)

I would get off of MPLS as your language server. I would switch to Pylance or Jedi as there's going to be better support for multi-root workspaces.

If you're still having trouble after that then let us know.
