code: def instantiate(__path: str, __mode: str, **kwargs: Any) -> Any:
      """
      Create an object instance or call a callable object from a class or function represented by ``_path``.
      `kwargs` will be part of the input arguments to the class constructor or function.
      The target component must be a class or a function, if not, return the component directly.
  
      Args:
          __path: if a string is provided, it's interpreted as the full path of the target class or function component.
              If a callable is provided, ``__path(**kwargs)`` or ``functools.partial(__path, **kwargs)`` will be returned.
          __mode: the operating mode for invoking the (callable) ``component`` represented by ``__path``:
  
              - ``"default"``: returns ``component(**kwargs)``
              - ``"partial"``: returns ``functools.partial(component, **kwargs)``
              - ``"debug"``: returns ``pdb.runcall(component, **kwargs)``
