isort can be configured using several configuration files, of which .isort.cfg and pyproject.toml are preferred, according to isort’s documentation. These are both recognised by mllint, although we recommend centralising tool configurations in your project’s pyproject.toml

Since mllint also recommends using Black, you should configure isort to be compatible with Black. This is done by putting the following in your pyproject.toml

[tool.isort]
profile = "black"
