how can I disable pylance analysis in vscode?

[alita-moore]

I don't need the pylance error analysis in my vscode project, I only want pylance enabled for linting of the currently edited file, how can I do this?

This setting will only provide errors for 'open' files:

"python.analysis.diagnosticMode": "openFilesOnly"

But I assume that's not good enough as it's the default.

This setting will force errors off for all files that match the glob pattern:

"python.analysis.ignore": ["./**/*.py"]

But then that would ignore the open file. You'd have to modify the ignore path to include your file instead.

Here's some more information on ignore:

That would match what the profile shows. The foreground thread is just busy reading thousands and thousands of files. And it looks like as a result of changing a setting.

If your venv was part of what it thought was the workspace, that would explain the problem.

yeah seems that was the issue, I'll update this if it turns out to not be the case. I think it's quite unintuitive / should be addressed. I was setting the exclusions to **/.venv which I would expect to match all the .venv folders in the packages but ti seems pylance was still indexing / reading those packages

[alita-moore]

also it would be really helpful potentially as a debug option if pylance gave a list of files that were being indexed (in some way that was possible to understand / visualize i.e. not just a giant log). It would have highlighted this issue immediately.

Hi @rchiodo
I found this thread while trying to debug why my pylance was hanging / unresponsive (even hovering a symbol in my code was just showing a wait message indefinitely). All resolved after disabling the analysis. Not sure which folder exactly caused this, but I assume it was either .venv (where I keep my virtual environment), or joblib cache (the latter containing hundreds of thousands of sub-directories for various cached calls from my code). Since both of these were in my .gitignore, I think pylance would benefit from also ignoring everything specified there.
