Seems there isn't a build for ARM. Turning on Jedi vs Language server makes a language server available. Ideal would be to not have to search and find this after a while (when not an expert, it might take some time :)).

(see issue 1884 on python-language-server)

Karthik Nadig (@karthiknadig) This was opened on the vscode repo, as it's an extension issue that it's downloading the LS on an unsupported platform. See microsoft/python-language-server#1884.

[jakebailey]

Moving this back; the issue here is that the platform checks aren't applying and the LS is being downloaded on an ARM system (when it should prevent MPLS from running and default back to jedi). IIRC the extension should have these checks, but maybe remote changes that dynamic.

We have recently released a new and more performant language server called Pylance which likely solves these issues you are reporting. You can download Pylance from the marketplace and install it alongside the core Python extension. Because our team's development efforts have shifted to support the new language server, we'd encourage you to try it out.
