pydantic BaseModel E0611

[vainaixr]

Bug description

I do

from pydantic import BaseModel

pylint says

E0611: No name 'BaseModel' in module 'pydantic' (no-name-in-module)

plus I do,

class UserModel(BaseModel):
    name: str
    age: int

it says R0903, too few public methods

Configuration

No response

Command used

pylint file_name.py

Pylint output

E0611: No name 'BaseModel' in module 'pydantic' (no-name-in-module)
R0903: Too few public methods (too-few-public-methods)

Expected behavior

there should be no issue with importing BaseModel from pydantic
if you see the way pydantic is used, both the issues should not be there

Pylint version

pylint 2.15.2
astroid 2.12.9
Python 3.11.0rc2

OS / Environment

No response

Additional dependencies

No response

Thank you for the report @vainaixr.

Using the following option suppresses both issues reported by your example:

pylint  --extension-pkg-whitelist='pydantic' example.py

[vainaixr]

even SQLModel uses similar class attributes convention, do I keep adding all libraries to whitelist.
the whitelist solution is a workaround, could the first one that is no name in the module be solved?
the second one is related to creating a class with only class attributes in it, I think so, that should also be allowed, considering even more libraries use a similar convention.

the whitelist solution is a workaround

You can also use --unsafe-load-any-extension=y. Be aware though that using this flag means that extensions are loaded into the active Python interpreter and may run arbitrary code, which you may not want. This is the reason why we disable by default loading C extensions.

You can disable too-few-public-methods if you don't like it, we're also going to make it optional in #3512
