@ -1120,11 +1120,6 @@ def typename(obj: _Any, /) -> str:
def is_tensor(obj: _Any, /) -> _TypeIs["torch.Tensor"]:
r"""Returns True if `obj` is a PyTorch tensor.
Note that this function is simply doing ``isinstance(obj, Tensor)``.
Using that ``isinstance`` check is better for type checking with mypy,
and more explicit - so it's recommended to use that instead of
``is_tensor``.
Args:
obj (object): Object to test
Example::
