The current version can handle importing pydantic without error just fine, but it probably can't find your virtualenv, so it doesn't know what third-party dependencies you have installed. Ty will discover your venv if it is in `.venv` in the project directory; otherwise you can help it out with the `--python` CLI flag.
We'll also discover your venv if you:
- Activate it manually (`source .venv/bin/activate`, etc.)
- Set the `VIRTUAL_ENV` environment variable
- Or use a command such as `uv run` or the equivalent from pdm/poetry/hatch to run ty (these project managers usually implicitly set the `VIRTUAL_ENV` variable to point to the project's virtual environment before executing any commands)
