Problem description

Tried to use this plugin with pylint to check my project.

this exception occurs:

Traceback (most recent call last):
  File "C:\Program Files\Python310\lib\site-packages\pylint_plugin_utils\__init__.py", line 44, in augment_visit
    checker = get_checker(linter, checker_method.__self__.__class__)
AttributeError: 'function' object has no attribute '__self__'. Did you mean: '__call__'?

During handling of the above exception, another exception occurred:

Steps to reproduce the problem

add this plugin name to the pylint rcfile to the variables defining plugins to load and extension whitelists

Specifications like the version of the project, operating system, or hardware

• pylint version: 3.0.3
• pydantic version: 2.5.2
• python version: 3.10.11

I can't repeat this issue. Please more information, like

def list_dependencies():
    import json
    import sys
    from importlib.metadata import version
    dependencies = ["pylint", "pylint_plugin_utils", "astroid", "pydantic", "pylint_pydantic"]

    return json.dumps({i: version(i) for i in dependencies} | {"python": sys.version}, indent=4)

print(list_dependencies())

And had load any other plugins?
