this error does not occur in terminal, but only in vscode pylint extension.

[Pierre-Sassoulas]

What are the versions used in the vscode extension ? You also need to check if you're in the same virtual environnement.

More detailed results were reported in the first comment.

I also checked that the selected virtual environment settings are the same as terminal and vscode selected interpreter.

Any progress? (Same issue here)

I'm experiencing the same problem, but I'm guessing it's an issue with the VSCode Extension (https://github.com/microsoft/vscode-pylint) and perhaps not specific to pylint-django. Seemingly the VSCode extension is (as of recently) failing to load the pylint-django plugin properly, regardless of whether I specify it with the pylint.args setting or in my .pylintrc. I'm not sure where to dig in further.

For what it's worth, I do see this near the top of the VSCode Pylint logs:
