One of your options is not recognized. There's nothing to change in your code, but your pylint configuration or the way you launch pylint needs to be modified.
For example, this message would be raised when invoking pylint with
pylint --unknown-option=yes test.py. Or you might be launching
pylint with the following toml configuration:
[tool.pylint] jars = "10"
When the following should be used:
[tool.pylint] jobs = "10"
This warning was released in pylint 2.14: bad options were silently failing before.
