hi @nasosev - sorry about this. This is because the current docs reflect marvin==2.x, which is a miss on our part. You can install the prerelease now with pip install marvin==2.0.1a1 or we will be releasing marvin 2 soon.

closing this as marvin 2.x has been released, which does not include prompt_fn
