It's recommended to use https://github.com/fannheyward/coc-pyright if you're using Python 3, or use https://github.com/pappasam/coc-jedi if you're using Jedi.

Looks like you don't have the jedi package installed for your python interpreter. I would expect it to work after you run (in your command line)

pip3 install jedi

I have also just seen that I installed the pynvim package in my python environment as well but I don't remember whether you need this.

When I started to edit .py file there were some notification but cause I was typing the notification was skipped and then it showed me [coc.nvim] Jedi error: import Jedi.

It turns out the notification asked me to select a python interpreter (I had two interpreters: one from anaconda and second from python.org). While I installed Jedi to 'python.org' interpreter, I didn't install Jedi to anaconda's python interpreter and hadn't selected which python interpreter to use.

So you should do either:

Select a python interpreter when prompted.
If there's no prompt then manually select python interpreter:

:CocCommand python.setInterpreter "C:\Users\username\AppData\Local\Programs\Python\PythonVersion\python.EXE"
or
:CocCommand python.setInterpreter "/usr/bin/python3"

And don't forget actually install Jedi: pip install jedi

YMMV but I got past that exact error by adding this to my :CocConfig "python.jediEnabled": false

can you still use stuff like go-to definition after doing that? – theonlygusti Oct 18 '20 at 13:39

To solve a similar problem I did the two following actions:

Install the last version of jedi:

pip install jedi --upgrade
Set the Coc Python interpreter to the version of Python I use (and for which jedi is installed)

In the C:\Users\myuser.vim\Coc-Settings.json make sure the following line is present

"python.pythonPath" : "C:\\Python36_x64",

Where "C:\Python36_x64" is the path of my Python interpreter

Remark: The Coc-Settings.json file is not in C:\Users\myuser\vimfiles (gVim) nor in C:\Users\myuser\AppData\Local\nvim (NeoVim) like the :CocConfig command would let you think it is.

One way to do this is by adding "python.pythonPath": "python3" to your coc-settings.json file.

If you are like me and uses lots of python virtual env or conda env then do the following:

Disable Jedi

$ vim ~/.config/coc/extensions/node_modules/coc-python/package.json
"python.jediEnabled": false,

Set following to you :CocConfig to solve the no interpreter issue.

"python", {
\   'jediEnabled': v:false,
\   'pythonPath': split(execute('!which python'), '\n')[-1]
\ }

Hope this helps ~
