Bug

Output of python -c "import pydantic.utils; print(pydantic.utils.version_info())":

             pydantic version: 1.9.0
            pydantic compiled: True
                 install path: /home/slado122/Programming/Tests/test_pydantic_mypy/.venv/lib/python3.10/site-packages/pydantic

Pydantic’s mypy plugin doesn’t work for me. The command to reproduce:

python -m venv .venv && source .venv/bin/activate && pip install pydantic && echo "[mypy]\nplugins = pydantic.mypy" > mypy.ini && touch a.py && mypy .

Output:
