I ran tito setup with Python version 3.9.6 but I got the following error.

(.venv) karthik@Karthiks-Mac-mini tinytorch % tito setup

Traceback (most recent call last):

  File "/Users/karthik/tinytorch/.venv/bin/tito", line 3, in <module>

    from tito.main import main

  File "/Users/karthik/tinytorch/tito/main.py", line 42, in <module>

    from .commands.update import UpdateCommand

  File "/Users/karthik/tinytorch/tito/commands/update.py", line 17, in <module>

    class UpdateCommand(BaseCommand):

  File "/Users/karthik/tinytorch/tito/commands/update.py", line 50, in UpdateCommand

    def _get_current_version(self) -> str | None:

TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

The install.sh requires 3.8+ but the Python pipe operator seems to have been introduced in 3.10, please update the script for checking version comptibility :)

I've been searching such a thing since years and now I have it. Consider me I love this initiative, thank you very much.

Best,
Karthik.
