<string>:68: SetuptoolsDeprecationWarning: Access to implementation detail
!!

        ********************************************************************************
        The function `convert_path` is not provided by setuptools itself,
        and therefore not part of the public API.

        Its direct usage by 3rd-party packages is considered improper and the function
        may be removed in the future.

        By 2023-Dec-13, you need to update your project and remove deprecated calls
        or your builds will no longer be supported.
