WARNING: it's recommended to use coc-pyright if you're using python3 or use coc-jedi if you're using jedi, the code of coc-python is too hard to maintain!
Python extension for coc.nvim, fork of vscode-python from commit 16899f6b13477786212f29eb3cb7a459b5ebf0a4.
Built with rich support for the Python language (for all actively supported versions of the language: 2.7, >=3.5), including features such as linting, IntelliSense, code navigation, code formatting, refactoring, snippets, and more!
关于 VS Code 中 python 的智障补全的解决方案，以 pytorch 为例
In your vim/neovim, run command:
:CocInstall coc-python
- To use Microsoft Python Language Server, add
"python.jediEnabled": falsein your settings file, coc-python would download latest stable MPLS for you. - Checkout
:h coc-statusto have statusline integration with coc.nvim, so you can get download status. - When jedi is not enabled, the language server will be downloaded. Make sure you have coc statusline integrated, check out
:h coc-status. - Install a linter to get errors and warnings -- you can further customize linting rules to fit your needs.
- Select your preferred Python interpreter/version/environment using the
python.setInterpretercommand.- Note the autoselected python interpreter could be wrong, make sure select the right one for you.
- Install
ctagsfor Workspace Symbols, from here, or usingbrew install ctagson macOS.
Open the Command List (use :CocCommand command in vim) and type in one of the following commands:
| Command | Description |
|---|---|
python.setInterpreter |
Switch between Python interpreters, versions, and environments. |
python.startREPL |
Start an interactive Python REPL using the selected interpreter in the VS Code terminal. |
python.execInTerminal |
Runs the active Python file in the VS Code terminal. |
python.setLinter |
Switch from PyLint to flake8 or other supported linters. |
python.upgradePythonLanguageServer |
Upgrade MPLS to latest daily version. |
To see all available Python commands, open the Command Palette and type Python.
Note: to enable multiple linters, edit the configuration file instead of use python.setLinter command.

Q: "python.linting.enabled": false not work when jedi disabled.
A: That setting only works when python files are used, not MPLS, you have to use "python.analysis.diagnosticEnabled": false to disable diagnostics from language server.
Q: MPLS using too much memory and CPU.
A: It's bug of MPLS, checkout microsoft/python-language-server#832.
Q: MPLS doesn't work with unsaved buffer.
A: Yes, it's not. You have to save your buffer to make it work.
Q: Get unable to find document error from MPLS.
A: Some filename would cause MPLS throw this error.
