IntelliJ IDEA says "unresolved reference" on everything (Python, virtual environment)

Question

How can I get IntelliJ IDEA to recognize common Python modules? IntelliJ IDEA is complaining "unresolved reference" on everything despite that I have added my virtual environment as a "Python interpreter" and invalidated caches. These (1)(2) related questions did not help resolve the issue.

I marked my root folder as "sources", but I couldn't find any place where I could check a box that says "add source roots to pythonpath". — Atte Juvonen, Mar 06 '18 at 22:25
@AtteJuvonen , Could you fix the issue? I've been trying to fix it for a couple of days. — ipeluffo, Apr 10 '18 at 09:38
No, I moved from IDEA to PyCharm because of this. Good luck! — Atte Juvonen, Apr 10 '18 at 15:54
@AtteJuvonen , today a new version of IntelliJ and Python plugin were released and they fixed the issue to me. Just give a try — ipeluffo, Apr 11 '18 at 09:22
@y.bedrov I did and it worked for a while but at some point the problem reappeared — Alvin, May 09 '18 at 15:44

The errors are caused by wrong source roots configuration. Your project doesn't know where to locate the reference.

Add a new content root From the main menu, select File | Project Structure⌘; and click Project Settings | Modules.

Select the necessary module and then open the Sources tab in the right-hand part of the dialog.

Click Add Content Root and specify the folder that you want to add as a new content root.

IntelliJ support discussed the same issue at here.

you can try this :

Project Structure -> SDKs -> "+" -> Python SDK

Project -> Project SDK -> Python 2.7.10 #Choose the python version that you want

I still have the same issue. – Houda M Dec 19 '19 at 11:24
which Python version are you using and on which OS – v015h3bn1k Dec 22 '19 at 17:06
I'm using Ubuntu 19.04, Python 3.8 and python 3.7 – Houda M Dec 31 '19 at 10:18
Solved it for me, seems like a restart of the IDE was necessary before the changes took effect. – Paul M. May 19 '23 at 14:22

This fixed for me when I setup the Python interpreter again. Apparently the problem was that the Python SDK's classpath was empty.
