Description
- I have checked that this issue has not already been reported.
- I have confirmed this bug exists on the latest version of pytask.
- (optional) I have confirmed this bug exists on the
main
branch of pytask.
Hey,
I again tried to use the functional interface. Actually, I wanted to use pytask for the very same task as last time when I failed to get it working with pytask (#625). I tested the latest version from pip (5.1.0) and today's main branch (https://github.com/pytask-dev/pytask/tree/5804f526e01ed1d7a262a43a0dbff8d9aed06e15) with the following code from https://pytask-dev.readthedocs.io/en/stable/how_to_guides/functional_interface.html:
from pathlib import Path
from typing import Annotated
import pytask
from pytask import task
def task_create_first_file() -> Annotated[str, Path("first.txt")]:
return "Hello, "
task_create_second_file = task(
name="task_create_second_file", produces=Path("second.txt")
)(lambda *x: "World!")
def task_merge_files(
first: Path = Path("first.txt"), second: Path = Path("second.txt")
) -> Annotated[str, Path("hello_world.txt")]:
return first.read_text() + second.read_text()
session = pytask.build(
tasks=[task_create_first_file, task_merge_files, task_create_second_file]
)
And I got the following result:
(bestofbothworlds) mnoppel@gpu08:~/bestofbothworlds$ python demo.py

Exit: pytask tried to launch a second live display which is impossible. the issue occurs when you use pytask on
the command line on a task module that uses the programmatic interface of pytask at the same time. Use either
the command line or the programmatic interface.
Collected 3 tasks.

So, for some reason it starts two sessions. But my code only starts one and is equivalent to the example.
Problem description
Mainly, it is a display bug again, similar to #621.
Expected Output
I was expecting only one pytask session to show up.
