TooManyLevelsError: Relative import with too many levels (n) for module

[NikolayVasilyev]

Reproduce

1. Use Sublime Text editor, install Anaconda package, install pylint and astroid with pip3
2. Write code with relative imports, like ("from .my_submodule import stuff")
3. Open the file with ST3

Current behavior

When I open sublime text editor with a python code with relative import, I see the following traceback from linter:

Traceback (most recent call last):

    sys.exit(run_pylint())

    raise TooManyLevelsError(level=level, name=self.name)
astroid.exceptions.TooManyLevelsError: Relative import with too many levels (1) for module 'rating'

Notes

If I manually change file: /usr/local/lib/python3.9/dist-packages/astroid/scoped_nodes.py from this:

724             if level and self.name.count(".") < level:
725                raise TooManyLevelsError(level=level, name=self.name)

to this:

724            if level and self.name.count(".") < level:
725                pass

Than everything goes fine, but linter says:
Unable to import '<cur_file>.<module>' (import-error)
But should be: `<top_level_dir_name>.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

~$ python3 -c "from astroid import __pkginfo__; print(__pkginfo__.version)"
2.6.5

Thanks.

It seems like the bug is in pylint. I've created an issue here: pylint-dev/pylint#4775

This was fixed in pylint in pylint-dev/pylint#4848
