• OS and version: 10.14

• Relevant/affected Python packages and their versions: N/A

Actual behavior

I have a list of Python packages that are not installed in site-packages under python.autoComplete.extraPaths. Jedi uses those paths to provide completions. The new LS does not seem to recognise them. I also get IntelliSense linter warnings when importing those packages, which doesn't happen with Jedi.

Expected behavior

The LS should treat the packages under python.autoComplete.extraPaths as if they were normally installed libraries.

Can you provide more details on repro and what is expected? Thanks

[albireox]

Sorry, I think I talked too fast. The path for one of the packages I keep in my python.autoComplete.extraPaths had changed and although I fixed it, it seems VSCode needed to be restarted for the change to register. The LS seems to be correctly autocompleting the packages in python.autoComplete.extraPaths.

I think this can be closed, although it would be nice if changes to python.autoComplete.extraPaths don't require a restart to take effect.

Ah, that is true. LS needs to be restarted when search paths change (Reload Window command is sufficient). I will rename the issue instead.

This is actually the behaviour I am currently seeing.
Use Jedi - packages in python.autoComplete.extraPaths have completions provided
Use LS without changing any other settings - packages referenced in extraPaths do not have completions provided.

Hello,

Is it possible to make this dynamic behaviour not only for searching for paths in the settings, but also for checking for any changes in tha packages specified by python.autoComplete.extraPaths? So if I do some changes in the package, the intellisense/autocomplete would mirror these updates dynamically and suggest for example for newly added modules and basically correspond to the newest version?

This behaviour is normal in the namespace of the project (it checks any changes in the current package and updates dynamically), is it possible to extend this functionality to the packages defined in the python.autoComplete.extraPaths?

Or just have some command to "refresh" the informations for selected packages, since the reloading whole vscode takes too long?

I hope I made myself clear, feel free to ask any additional questions if you didn't understand me what I've meant exactly.

Thank you very much

Should be addressed by microsoft/python-language-server#1492

Closing as this has been resolved upstream.
