ok this issue is definitely with the chose python interpreter.
- check what is the version of python you are using
- check whether you are using wsl on windows or linux or command prompt
now in my case choose the interpreter was not solving the issue. I even tried the virtual environment and giving a path. but python by default was installing the .exe in a hidden folder and i couldn't find the files in the env folder
i was using wsl on windows and visual studio code.
so i ran pip installed outside the env. and also on the powershell/cmd and the terminal. and the error went away.
Hi, my Oobabooga installation suddenly stop working today. It was working fine yesterday and today I am getting this error:
ImportError: cannot import name 'Undefined' from 'pydantic.fields' E:\Oobabooga\installer_files\env\lib\site-packages\pydantic\fields.py)
I am on windows and don't know much about linux or python. I already tried update a couple of times and it's saying I am up to date. Any idea for a quick fix?
This is a common problem with binary/C extensions. For further details, check here: (Pylint & C extensions)
To fix it, you need to add the following to .pylintrc file (You can add this file to your current project folder if you like)
[MASTER]
extension-pkg-allow-list=pydantic
Note that switching to mypy (as suggested by another answer here) is not the right approach since pylint & mypy are two different things (the former is a linter while the latter is sort of a type checker)
The first thing that you noticed
pydantic BaseModel not found in Fastapi
is related to your linter.
I got the same warning when my linter was pylint, so I changed the linter from pylint to mypy and the problem disappeared.
Install mypy via pip
pip install mypyOpen the command palette in VScode
Ctrl+Shift+PType this in command palett:

What i have done Migration Guide
pip install pydantic-settings
I replaced in my code:
# from pydantic import BaseSettings # OLD
from pydantic_settings import BaseSettings # NEW
In pydantic-V2, Settings management has been moved to a separate package named pydantic-settings.
You can install it by pip install pydantic-settings.
If you still want to have V1-style settings management in V2, you can import it like:
from pydantic.v1 import BaseSettings
