Pylint complains about "No name 'SecretStr' in module 'pydantic'"

Bug

Pylint complains about missing pydantic data types but they can be used without problems.

I see this problem inside this Docker image: tiangolo/uvicorn-gunicorn-fastapi:python3.7. It does not occur in my dev environment under MacOS.

Please complete:

• OS: Linux
• Python version import sys; print(sys.version): *3.7.4
• Pydantic version import pydantic; print(pydantic.VERSION): 0.32.2

Where possible please include a self contained code snippet describing your bug

Put this content into app.py:

"""app.py"""
from pydantic import SecretStr

SECRET = SecretStr('ab')

Then install pylint with pip install pylint and run pylint app.py

--extension-pkg-whitelist=pydantic solves this.

Just for the sake of completeness, here is the explanation to why this option is required: http://pylint.pycqa.org/en/latest/technical_reference/c_extensions.html
