+1 - I have the same problem with

VS Code 1.29.1 Microsoft Python Language Server version 0.1.65.0 Python Extension 2018.11.0 Python 2.7.15 (venv-based environment)

My python.autoComplete.extraPaths setting is also []. I tried to disable Jedi and Linting. I keep killing the process to keep my Macbook’s fans from spinning, but it always respawns at 100% CPU usage.

Is there any way to disable the language server? I believe my only option right now is to disable the python extension completely.

This happens for me too. Python 2.7 with a moderately big project. What Info can I provide to help debug this?
